Audi A8 L Hybrid

The Audi A8 hybrid, which debuts spring 2012, is the world's most efficient luxury-class hybrid sedan and also the only European full hybrid in the segment. It has an all-electric range of up to three kilometers.

The Audi A8 hybrid combines the performance of a six-cylinder with the fuel economy of a four-cylinder model. With 180 kW (245 hp) of system power, the 2.0 TFSI and the electric motor deliver powerful thrust, yet the brand's flagship consumes just 6.3 liters of fuel per 100 km (37.34 US mpg). The ultra lightweight aluminum body plays a major role in this efficiency.

The Audi A8 hybrid is a parallel hybrid - a high-efficiency concept. Its 155 kW (211 hp) 2.0 TFSI and the electric motor are mounted one directly behind the other and are linked by a clutch to work together, when necessary. System output is 180 kW (245 hp) and peak system torque is 480 Nm (354.03 lb-ft). The power is delivered to the front wheels via a highly modified eight-speed tiptronic. The lithium-ion battery in the rear provides 1.3 kWh of energy, and its sophisticated air cooling system switches between two stages as needed.

The Audi A8 hybrid combines the performance of a six-cylinder with the fuel economy of a four-cylinder model. The sprint from 0 to 100 km/h (62.14 mph) takes just 7.7 seconds, and top speed is 235 km/h (146.02 mph). In the standard cycle, the large sedan consumes just 6.3 liters of fuel per 100 km (37.34 US mpg) on average - a CO2 equivalent of 147 grams per km (236.57 g/mile), and easily the best in its class.

In all-electric mode, the Audi A8 hybrid can cover roughly three kilometers (1.86 miles) at a speed of 60 km/h (37.28 mph). Top speed in this mode is 100 km/h (62.14 mph). The driver can choose between three driving programs, on the basis of which the hybrid manager - the control unit in the drivetrain - selects the best suited of five operating modes.

With a curb weight of 1,870 kg (4,122.64 lb), the Audi A8 hybrid is by far the lightest hybrid sedan in its class. This top value is due in part to the fact that the additional components weigh in at only around 130 kilograms (286.60 lb) and also to the ultra lightweight body. Featuring an aluminum Audi Space Frame (ASF), it tips the scales at just 231 kilograms (509.27 lb).

The chassis of the A8 hybrid also benefits from Audi's expertise in ultra lightweight construction, combining excellent ride comfort with sporty handling. The links are made of a lightweight alloy; the power steering uses a special electromechanical drive. The Audi drive select dynamic handling system and adaptive air suspension with damping control are standard. The large 19-inch wheels sport a special hybrid design.

Timeless and distinctive: the design

The exterior design of the large sedan is one of timeless elegance. The standard LED headlights give the front end an unmistakable expression. The Audi A8 hybrid is 5.14 meters (16.86 ft) long; the long-wheelbase Audi A8 L hybrid is 13 centimeters (5.12 in) longer.

The interior features sporty and lightweight lines, simple controls and a finish of handcrafted quality. The driver can read all key information about the hybrid drive on special displays. The seats are available with optional ventilation and massage functions, while the ambient lighting package uses LEDs to set subtle accents. Other features include a continuous center console and a folding table.

Audi offers a wide range of infotainment systems for the A8 hybrid. The Bose surround sound system is standard, with a high-end system from Bang & Olufsen available as an option. The optional navigation and infotainment system MMI navigation with MMI touch includes a touchpad for entering letters and numbers.

The ideal complement to this media center is the online Bluetooth car phone, which connects to the Internet via UMTS. Passengers can use its integrated WLAN hotspot to surf and e-mail. For the driver, the system delivers the services of Audi connect to the vehicle, including up-to-the-minute Audi traffic information online.

The assistance and safety systems that Audi offers in the A8 hybrid are also state of the art. These include the night vision assistant with highlighting of detected pedestrians and a parking system that supports the driver with four small cameras. The safety system Audi pre sense basic is also standard.

The Audi A8 hybrid will launch in Europe in May 2012. The standard-wheelbase version has a base price of €77,700, while the long version lists for €85,400.

Drivetrain

The Audi A8 hybrid is designed as a parallel hybrid - a straight-line concept with high efficiency. Its combustion engine and the electric motor are located one directly behind the other and are linked by a clutch to work together, when necessary. The interplay between the combustion engine and the electric motor briefly results in a peak system output of 180 kW (245 hp) and a maximum system torque of 480 Nm (354.03 lb ft).

The Audi A8 hybrid combines the performance of a six-cylinder with the fuel economy of a four-cylinder model. The sprint to 100 km/h (62.14 mph) takes 7.7 seconds, and top speed is 235 km/h (146.02 mph). In the standard cycle, the luxury sedan consumes just 6.3 liters of fuel per 100 km (37.34 US mpg) on average - a CO2 equivalent of 147 grams per km (236.57 g/mile) and easily the best in its class. For the Audi A8 L hybrid, these figures (all figures provisional) are 7.9 seconds, 228 km/h (141.67 mph), 6.4 liters per 100 km (36.75 US mpg) and 149 grams of CO2 per km (239.79 g/mile). The 75 liter (19.81 US gallon) tank gives both versions a long range.

The 2.0 TFSI displaces 1,984 cc and produces 155 kW (211 hp). Its maximum torque of 350 Nm (258.15 lb-ft) is available between 1,500 and 4,200 rpm. The four-cylinder engine, which has been chosen as Engine of the Year five times in a row, combines gasoline direct injection with turbocharging - typical for the Audi philosophy of downsizing, which replaces displacement by forced induction.

The Audi valvelift system (AVS) further increases power, torque and efficiency by switching the stroke of the exhaust valves between two stages depending on the load and engine speed.

The 2.0 TFSI has been overhauled in some respects for use in the Audi A8 hybrid. The mechanical belt drive for the auxiliaries was eliminated; it was electrified for the hybrid. A secondary air system at the cylinder head makes sure that the exhaust gas treatment cuts in particularly fast after cold-starting.

Quiet on board: Active Noise Control

The Audi A8 hybrid comes standard with Active Noise Control (ANC). This innovative system eliminates intrusive engine noise by broadcasting a precise antiphase sound to the cabin through the sound system's speakers. This principle is known as interference: If two waves of the same frequency are superimposed, their amplitudes cancel each other out provided that they are equal and 180 degrees out of phase from one another.

A highly modified eight-speed tiptronic transfers the power to the front wheels. Instead of a torque converter, it includes the disk-shaped electric motor, which is combined with a multi-plate clutch operating in an oil bath. The clutch connects and disconnects the electric motor and the TFSI very precisely and gently.

With its eight widely spaced gears, the comfortably and fast-shifting hybrid transmission contributes significantly to the efficiency of the Audi A8 hybrid. When the 2.0 TFSI is deactivated, an electric pump maintains the oil pressure in the hydraulic system to safeguard the convenient start-stop feature.

The power electronics, connected to the battery and the electric motor by high-voltage cabling, are located in the plenum chamber of the engine compartment. They serve as a controller between the battery, which outputs direct current, and the electric motor, which operates on alternating current. Innovative technologies keep the volume and weight of the component low, with cooling provided by a separate water-filled circuit. The power electronics include a DC/DC converter that connects the consumers in the 12 V electrical system to the high-voltage network.

Electric drive is a permanent magnet synchronous machine; it serves as an electric motor, as a starter and - during deceleration - as a generator. The electric motor, which delivers up to 40 kW (54 hp) of power and 210 Nm (154.89 lb ft) of torque, is integrated into the engine's cooling system.

Energy is stored in a lithium-ion battery system weighing a mere 38 kg (83.78 lb). It is located in a crash-safe area of the trunk and protected by a separate housing. The battery consists of 72 cells; at 266 volts its normal energy is 1.3 kWh and its power 39 kW.

The lithium-ion battery is cooled by air in two ways. At low-temperature load, it draws temperature-controlled air from the vehicle interior by way of a fan. If its temperature exceeds a certain limit, a separate refrigerant circuit is activated. It is coupled to the main climate control system of the vehicle and uses a separate evaporator. This powerful active cooling makes Audi A8 hybrid superior to many other hybrid vehicles.

Driving states

The driver of the Audi A8 hybrid can use a button on the center console or the tiptronic selector lever to choose between three driving programs. The EV characteristic map gives priority to the electric drive; the D mode controls both motors efficiently; and the S mode as well as the touch control gate of the 8‑speed tiptronic are designed for a sporty driving style.

The hybrid manager, a proprietary Audi development, is integrated into the control unit of the 2.0 TFSI and manages the transition between the modes. The Audi A8 can be driven in five different modes. Driving with the combustion engine alone, with the electric drive alone or in hybrid mode is possible, as are recuperation and boosting. None of its European competitors in this segment offer such a broad spectrum.

Both drive sources are deactivated when the vehicle is stationary. In this convenient start/stop mode, the automatic air conditioning remains active - its compressor has a high-voltage electric drive and is supported by a separate auxiliary heater.

Once the driver releases the brake, the Audi A8 hybrid starts rolling. It can drive at up to 100 km/h (62.14 mph) in all-electric mode. At a constant 60 km/h (37.28 mph), it has a range of up to three kilometers (1.86 miles) - enough for most residential areas. Top speed with the electric drive is 100 km/h (62.14 mph) - another best.

The TFSI becomes the power source as soon as the driver accelerates further. In many situations, the engine management system increases the load somewhat in order to operate at the ideal point with respect to fuel consumption. The excess energy flows to the electric motor, which uses it to supply on-board consumers and to recharge the battery. When accelerating quickly, or "boosting," the electric motor operates together with the TFSI; at full throttle, the full system output is briefly available. The hybrid drive then supplies the propulsion power of a large, naturally aspirated engine, but with far more efficiency.

When the driver releases the accelerator, the electric motor recovers energy and stores it in the lithium-ion battery. In most situations the TFSI is then decoupled from the drive system and does not cause any drag losses. "Gliding" like this is possible up to 160 km/h (99.42 mph). If the driver only brakes slightly, the electric motor performs the deceleration itself; during more forceful braking, the hydraulic braking system is simultaneously activated. A complex control strategy adapts all braking actions to the conditions of electric driving and energy recuperation.

Well informed: the hybrid displays

The Audi A8 hybrid has a display concept on board for making the driving states of the hybrid drive tangible to the driver. A power meter replaces the rev counter in the instrument cluster; its needle indicates the drive's total output on a scale of 0 to 100 percent. Color segments with green and orange sections show at a glance how efficiently the large sedan is currently operating. An additional instrument displays the charge level of the lithium-ion battery.

At the same time, the energy flow display clearly depicts the current mode of operation and active components of the hybrid drive. It can be called up via the driver information system and the MMI monitor. The large screen shows a bar diagram of the average consumption and presents the amount of energy recovered in five-minute increments.

Chassis

The Audi A8 hybrid combines luxurious ride comfort with sporty handling. Most of the components of its five-link front suspension and the self-tracking trapezoidal-link rear suspension are made of aluminum. The wheel brakes are large. Based on a concept from sports car design, pins connect the internally vented, cast iron friction rings to the aluminum brake caps. The ESC stabilization system offers a sport mode and includes a tire pressure monitoring system.

The adaptive air suspension, which includes controlled damping, is standard. The system modifies the performance of the dampers depending on the condition of the road and the driver's style. It adjusts the body's ride height in multiple steps in line with the car's speed and is also used to level the suspension. Audi also delivers the A8 hybrid with the optional adaptive air suspension sport, which features a standard ride height that is 10 millimeters (0.39 in) lower.

The adaptive air suspension is integrated into Audi drive select. This dynamic handling system enables the driver to switch the function of the engine management system, the hybrid transmission and the power steering between the four modes "comfort," "auto," "dynamic" and "custom." The belt tensioners in the safety system Audi pre sense basic can also be adjusted via Audi drive select.

Anthracite-colored, semi-polished 19-inch wheels of "Turbine" design and fitted with 255/45 R19 tires are standard. Optional 20-inch wheels with a 10 parallel-spoke design and shod with 265/40-series tires provide even greater dynamics.

Two key chassis components have been modified for electric operation. The hydraulic power steering has been replaced by an electromechanical unit that adjusts its level of boost according to the vehicle's speed.

Because it consumes no energy when the car is traveling in a straight line, it saves around 0.3 liters of fuel per 100 km. The electromechanical power steering is designed for a direct, sporty response.

Body

With a curb weight of 1,870 kilograms (4,122.64 lb), the Audi A8 hybrid is the lightest car in its class. It brings the full range of the Audi's ultra lightweight technology expertise to the streets. The special technical components and equipment features for the hybrid drive contribute just 130 kilograms (286.60 lb) of additional weight.

Except for the B-pillars, where hot-shaped, ultra-high-strength steel is used, the luxury sedan's ASF (Audi Space Frame) body is made entirely of aluminum. Weighing just 231 kilograms (509.27 lb), it is roughly 40 percent lighter than a comparable steel construction. The body of the Audi A8 L hybrid, which is 13 centimeters (5.12 in) longer, weighs 241 kilogram (531.31 lb).

The ASF body of the A8 hybrid, assigns a specific task to each material and each component. The cast nodes connect the components, the extruded sections bridge spaces, the aluminum panels close off the spaces and lend rigidity to the framework. The material is used only where necessary and always in a tailored configuration.

The ASF body, for which Audi received the Euro Car Body Award, the world's highest honor for innovative car body design, has other strengths as well. It is very rigid and offers good protection in the event of a collision. The Audi adaptive restraint system also stands guard in the cabin. Both body variants of the A8 hybrid have a drag coefficient of just 0.26, thanks in part to the extensive fine-tuning of the underbody and in the engine compartment.

The ASF design ensures comfortably low levels of vibrations and impressive quietness, with additional noise reduction provided by an acoustically insulated windshield. If desired, Audi can also provide noise-insulating side windows of dual-pane acoustic glass, with tinting optional. A panoramic glass sunroof is available for the long version.

Exterior design

The exterior of the Audi A8 hybrid has a cohesive, homogenous appearance. The coupe-like roofline with the inclined C-pillars makes the silhouette flow. Sculptured surfaces conveying calmness and prestige contrast with sharp lines. The luxury sedan is 5,137 millimeters (202.24 in) long, 1,949 millimeters (76.73 in) wide and 1,460 millimeters (57.48 in) tall; its wheelbase measures 2,992 millimeters (117.80 in). For the Audi A8 L hybrid, these figures are 5,267 millimeters (207.36 in) long, 1,949 millimeters (76.73 in) wide and 1,471 millimeters (57.91 in) tall. The wheelbase measures 3,122 millimeters (122.91 in).

The single-frame radiator grille of the Audi A8 hybrid is three-dimensional and rich in detail. The standard LED headlights use light-emitting diodes for all lighting functions. They give the sedan a distinctive appearance, do an excellent job of illuminating the road and are highly efficient. The integrated high-beam assistant switches automatically between low-beam and high-beam headlights. The rear lights also feature sophisticated LED technology.

Small hybrid badges on the trunk lid and the fenders indicate the new drive concept. 11 paint finishes are available, with Arctic Silver available as an exclusive option. The engine hood and key of the A8 hybrid also feature a unique design.

Interior

Audi has its own unique philosophy when it comes to luxury. Luxury does not mean excess, but rather individual, cultivated style. The selection and workmanship of all materials in the interior of the A8 hybrid are on a hand-built level. The light, elegant interior design conveys the large sedan's athletic character. A large arc - the wrap-around - encircles the cockpit. The front of the instrument panel is in the shape of a gentle wave.

The front seats feature 12-way electric adjustment. Audi also offers a number of seating options up to the comfort sport seats. These can be further upgraded with a ventilation system for the seat surface and backrest, and a massage function with ten air cushions, five programs and five intensities to pamper the back.

The A8 hybrid has clearly structured, intuitive ergonomics. The driver information system with 7-inch screen concentrates all important information and settings in a logical menu structure. The driver can operate it via the leather multifunction steering wheel. The MMI with its elegant, power-retractable 8-inch monitor serves as a second control unit. Its control terminal with the large rotary pushbutton is located on the console of the center tunnel, ideally positioned for the driver's right hand.

The standard three-zone automatic air conditioning enables quiet and low-draft indirect ventilation through a grate on the top of the instrument panel. It controls the temperature of the driver and passenger areas plus the back seat, and offers three climate styles. The ambient lighting, another standard feature, is an artistic overall orchestration of LEDs, light guides and light strips. Many LEDs are two- or three-colored. The driver can use the MMI control system to choose between and make fine adjustments to three different lighting scenarios.

Luxurious: the spacious rear seat

The extended wheelbase of the Audi A8 L hybrid provides for a generous amount of space in the back. Audi offers the option of two power-adjustable and heated individual rear seats. These can also be equipped with optional ventilation and massage functions, and features such as a folding table and a continuous center console make the passengers' journey even more enjoyable.

Audi offers the interior components of the A8 hybrid in a variety of colors. The headlining is available in a choice of three shades. A choice of three grades of leather and a leather/Alcantara combination is available for the seat upholstery. The two-segment decorative inlays are also available in a number of fine materials. The entry sills feature aluminum strips with hybrid logos, and an additional hybrid badge adorns the instrument cluster. A number of additional suggestions for further customization are included in the Audi exclusive program.

The trunk of the Audi A8 hybrid features a luggage capacity of 335 liters (11.83 cu ft) and a low loading lip. As standard, Audi includes a five-piece luggage set designed to optimally fill the available space. The trunk lid opens automatically when unlocked, and a power-assisted function helps to close it. Foot control of the trunk lid is available as an option.

Driver assistance systems

The Audi A8 hybrid can be optionally equipped with a series of assistance systems that make driving even more relaxing and composed. Audi side assist, whose radar sensors monitor what is happening behind the car, warns the driver of critical lane changes. It is activated upon reaching 30 km/h (18.64 mph).

Audi lane assist, which is active at speeds of about 65 km/h (40.39 mph) and above, uses a camera to observe the lane markings. If the driver approaches one of them without using the turn signal, there is an adjustable vibration at the steering wheel. The speed limit display recognizes speed limit signs and presents them on the display of the driver information system and on the MMI monitor. The parking system plus with surround view camera makes parking easier.

Four small cameras monitor the surroundings of the car. A computer combines their images and displays them in a variety of views.

The night vision assistant with highlighting of detected persons uses a far infrared camera that reacts to radiated heat. It displays the information it collects as black-and-white images on the display of the driver information system. The cooler surroundings appear dark, while people and animals are conspicuously bright. The system, which has a visual range of up to 300 meters (984.25 ft), can detect people at up to 100 meters (328.08 ft) away and highlights them with yellow markings. In a hazardous situation, they are marked red and a warning gong sounds.

A standard feature in the A8 hybrid is the safety system pre sense basic. If the ESC sensors report a critical state, the control unit activates the hazard warning lights and closes the side windows and the sunroof, depending on the situation; it also tensions the front seat belts and emits a tone to warn the driver.

If Audi side assist is also on board, then there is also the function pre sense rear, which mitigates the consequences of a rear-end collision.

Infotainment

An attractive lineup of infotainment modules is available for the A8 hybrid. Their centerpiece is MMI navigation plus. The high-end system includes a 60 GB hard disk, a DVD drive and a whole-word voice control. A fast graphics processor generates top-quality, three-dimensional images that are displayed tack sharp in vibrant colors on the 8-inch monitor.

MMI navigation plus also includes MMI touch. The driver enters a destination or the telephone number by drawing the letters and numbers - even using characters from Asian languages - on the touch-sensitive control panel with a finger. The system provides acoustic feedback after each character so that the driver's eyes can stay on the road.

MMI navigation plus works closely together with the other systems in the A8 hybrid. It looks ahead on the route selected and forwards all relevant data to the controllers that, for example, control the headlights and can thus illuminate bends or junctions early on. They also influence the way the hybrid transmission works. This means that these systems can adapt their function precisely to the given conditions.

The Audi A8 hybrid comes standard with the Bose surround system. A digital amplifier drives 600 watts to 14 speakers including a subwoofer to produce a finely balanced and simultaneously powerful sound on a strong base foundation. The system can also play stereo recordings in five-channel surround sound.

The Bang & Olufsen Advanced Sound System is a high-end alternative for hi-fi connoisseurs. It drives 19 active speakers with aluminum grilles via two amplifiers with over 1,400 watts of power. Located in the instrument panel are two acoustic lenses for the high frequencies. They extend outward when the system is switched on.

Upon request, Audi equips the A8 L hybrid with the rear seat entertainment system, which includes a separate DVD drive and a hard disk jukebox.

Mounted on the backs of the driver and front-passenger seats are two 10.2-inch displays that can display different content. Sound is supplied via the audio systems or two sets of Bluetooth headphones. Additional components such as a tuner for digital radio reception and a TV tuner round out the infotainment lineup.

Audi connect

The term Audi connect refers to all applications and developments that connect Audi cars to their owner, the Internet, the infrastructure, and other vehicles. The hardware module for this is the Bluetooth car phone online, an additional component of MMI navigation plus. It connects to the Internet via a UMTS module. Passengers can connect up to the eight mobile terminal devices to the integrated WLAN hotspot.

The Bluetooth online car phone is operated either via the MMI navigation plus terminal, using the multifunction steering wheel or by voice control. Data are encrypted and transferred via the roof antenna at rates of up to 7.2 MB per second. If the A8 hybrid is traveling outside the UMTS network, the system switches to the EDGE standard.

For the driver, the online Bluetooth car phone brings tailored Internet services to the A8 hybrid. These range from navigation using images from Google Earth to voice-controlled Google POI search and Google Street View to Audi traffic information online, which provides a precise, highly differentiated image of the traffic load along the chosen navigation route.

Market

The Audi A8 hybrid will begin start arriving at dealers in Germany and all other European countries in May 2012. The standard-wheelbase version has a base price of €77,700, while the long version, which will follow a short time later, costs €85,400. A large share of the production is intended for export markets, primarily China.

Most of the future customers for the Audi A8 hybrid are relatively young, highly educated and have a high income. They have an open, cosmopolitan lifestyle with strong cultural interests and are striving to bring their economic success into harmony with ecological responsibility.

Audi Q3 Vail Concept

The Audi Q3 Vail represents a new, potential variation on the SUV concept. The themed vehicle has been designed for young fans of winter sports who love skiing or snowboarding. The Audi Q3 Vail is a sporty and robust compact SUV offering many practical attributes, an elegant appearance and individual design highlights.

The themed vehicle is painted in the color developed specially for it - Energy Red. The red paint contains golden pearlescent particles. The add-on body parts are in matt gray quartz-based paint, and underline the vehicle's robust and rugged appearance. The high-gloss package, a characteristic feature of the model line, enhances the area around the windows with eye-catching elements in aluminum and high-gloss black.

Vertical struts made from aluminum are integrated in the single-frame grille. They extend across the full height of the grille. In the area of the horizontal panel, which carries the license plate on series-built vehicles, they are pulled outwards to striking effect.

The struts exhibit the bicolor theme that the Audi designers developed for the Audi Q3 Vail: their lateral edges are painted in matt quartz-based paint, and the slim front faces have a high-gloss finish.

In the headlights the zones in the lower area of the light-guide elements, which generate the daytime running lights, are painted anthracite. The side air inlets further emphasize the themed vehicle's powerful appearance; their top areas are covered by solid aluminum panels. The underbody guard beneath the front end is also made from aluminum.

Eyecatching features on the sides of the Audi Q3 Vail are the flared wheel arches and running boards, which Audi is to incorporate into the extensive range of Q3 accessories. The restyled aluminum roof rails are specially designed for transporting skis and snowboards - these two items of sports equipment are made from carbon fiber.

The front roof-rail support integrates compact, energy-efficient, wide-angled LED lights that illuminate the area around the Audi Q3 Vail. They are controlled via buttons in the roof module.

The Audi Q3 Vail is fitted with five-arm wheels in 8.5 J x 20 format. Mirroring the single-frame grille, their visible edges have a high-gloss finish, while the inside areas feature the same matt quartz-based paint. The off-road tires are size 255/45. Track width has increased 40 millimeters (1.57 inches) at the front and rear compared to series-built models, and the body is 30 millimeters (1.18 inches) higher. The themed vehicle also features unique solutions at the back - the two tailpipes of the dual-branch exhaust system are integrated in the diffuser and underbody guard area.

In the interior of the Audi Q3 Vail, three colors offer an ambience of sophistication and sporty elegance - black, gray and red. The headlining is made from titanium gray Alcantara; large parts of the interior, including the carpet, are black. The black, ribbed floor mats are edged with narrow strips of red velvet-finish leather.

An innovative leather/fabric material is used for the upholstery - thin strips of leather just a few tenths of a millimeter wide, are interwoven with yarn. The upholstery features piping with double seams; like the contrasting stitching, the piping is red. Small sections of the upholstery are made from red velvet-finish leather - a hardwearing material that looks similar to nubuck leather at first glance, but in fact has a finer structure. The segments integrated in the door trims are also in red velvet-finish leather, trimmed in steel gray Fine Nappa leather.

The entire instrument panel in the themed vehicle is trimmed in black Fine Nappa leather. Contrasting stitching in titanium gray is an elegant highlight. The leather across the hood of the instrument cluster is steel gray with red contrasting stitching. This color scheme is replicated on the door armrests at the front and rear. The front section of the center tunnel also has a leather trim.

The inlays around the S tronic selector level, at the front of the cockpit and in the doors comprise a three-dimensional stainless steel mesh that requires a complex manufacturing process. The selector lever features a high-gloss black ring and an aluminum badge with a milled "Q3 Vail" signature. The lever gaiter is enhanced by red stitching.

Aluminum takes center stage in the instrument cluster. The most striking elements are the metal dials around the speedometer and rev counter. They were made using a rotary-grinding process. Metal is also used on their rings and around the edges of the control lights. Horizontal bars and small fins give the dials and needle centers a sporty, three-dimensional look. The leather steering wheel features red contrasting stitching and an aluminum trim. Behind it are two large shift paddles for manually controlling the seven-speed S tronic. The footrest and the pedals have thin pads made from rubber. Slits offer a glimpse of the stainless steel beneath the pads.

In some parts of the interior the trims are in high-gloss black - the display and control elements on top of them appear to float. This applies to the area surrounding the driver information system, the zone around the air vents, the periphery of the MMI terminal and the row of switches on the center console. Aluminum inserts give the black switches an air of sophistication. Chrome trims adorn the controls of the air conditioning system; the air vents have black ribs and chrome-trimmed rotary knobs.

The soft keys for the MMI navigation plus system are made from aluminum, while the control terminal benefits visually from narrow strips of the same material. The monitor, which can be folded out manually, has a trim that matches the surface of the instrument panel. The system includes an animation showing the longitudinal and latitudinal tilt angle of the Audi Q3 Vail. In regions that are not included in the map data, the MMI navigation plus system logs the GPS coordinates of the route - for assistance during the return journey.

The interior of the Audi Q3 Vail includes two practical devices for winter sports fans. The side wall of the trunk houses a charging station. It can be used for storing flashlights and charging them inductively at the same time. The same technology is used for the Thermos bottle. It is located in the cup holder between the front seats and is able to chill or warm drinks. Both devices have LEDs that show the current charge level. One attractive extra is that, in addition to LED lighting, the flashlights incorporate an infra-red heating element that can be used for warming your hands or a pair of ski boots.

Another intelligent solution in the themed vehicle is the trunk mat, which has integrated heated seat cushions. The mat can be folded out and laid over the loading lip. This protects the trunk edge while the vehicle is being loaded or unloaded, and also provides a warm area to sit on when putting on or taking off your ski boots. Small LED spotlights on the inside of the tailgate provide light.

The Audi Q3 Vail features a 2.5-liter five-cylinder TFSI engine with direct injection and turbocharging that generates an output of 231 kW (314 hp) and 400 Nm (295.02 lb-ft) of torque from a displacement of 2,480 cc.

The engine's five cylinders are consecutively numbered; red wrinkled-finish paint has been applied to the cylinder head cover. A panel made from carbon-fiber-reinforced polymer (CFRP) partially covers the engine, and the air filter is also protected against dirt. There is a decorative trim made from plastic around the engine compartment. The acoustic mat on the inside of the engine hood has a "Q3 Vail" logo embroidered in dark gray.

The power of the turbocharged five-cylinder unit is transferred to the quattro permanent all-wheel drive system via a seven-speed S tronic transmission. The Audi Q3 Vail accelerates from zero to 100 km/h (62.14 mph) in 5.5 seconds and continues to a top speed of 262 km/h (162.80 mph).

Audi A6 allroad quattro

The new A6 allroad quattro is 4.94 meters (16.21 ft) long, 1.90 meters (6.23 ft) wide and 1.47 (4.82 ft) meters tall, making it a few millimeters bigger than the Avant. It follows the Audi ultra lightweight construction principle familiar from the sedan, with aluminum components making up roughly 20 percent of its body. Total vehicle weight has been reduced by as much as 70 kilograms (154 lb) compared with the previous model.

The Audi A6 allroad quattro has a sportily distinctive road stance. It features balanced proportions, sharp lines delineate taut surfaces and the roof line flows into flat D-pillars. Audi offers progressive LED technology as an option for the headlights and tail lights. The xenon plus headlights can be combined with adaptive light, which ensures that the road is always properly illuminated for the situation at hand.

The body of the new Audi A6 allroad quattro sits six centimeters (2.36 in) higher than that of the A6 Avant. Setting it apart are, in particular, the trim strips on the side sills, the more widely flared fenders and the single-frame grille with vertical slats. Stainless steel covers protect the underbody at the front and rear of the car, and the exhaust system ends in two large, flattened tailpipes. The roof rails are mounted on double bars.

The wheel well edges, the bumpers and the sills are painted in a contrasting color. Audi also offers a full paint finish in combination with the optional aluminum exterior package. The color Java Braun is available exclusively for the new Audi A6 allroad quattro.

Interior and luggage compartment

The interior of the Audi A6 allroad quattro offers plenty of space thanks to the long wheelbase of 2.91 meters (9.55 ft). It features a lean, elegant design, exemplarily clear ergonomics and superior workmanship. A function that depicts the car's pitch has been added to the MMI operating system, the soft keys of which are gleaming aluminum. MMI comes as standard, as does the onboard computer with efficiency program. A comprehensive package of restraint systems helps to mitigate the consequences of an accident.

Visual cues differentiating the Audi A6 allroad quattro include the carpeting and the instrument panel, which are black throughout. Other refined details include the interior color Santos Brown and the optional aluminum inlays. The door sill trims are also made of aluminum and are emblazoned with "allroad."

The luggage compartment of the new Audi A6 allroad quattro has a capacity of 565 liters (19.95 cu ft). Latches in the luggage compartment make it easy to fold down the rear seats, increasing luggage capacity to 1,680 liters (59.33 cu ft). Standard equipment features underscore the practical character of the new model - a rail system with an included load-securing kit for dividing the luggage compartment as needed, tensioning straps on the left wall and a double loading floor.

Equipment and Audi connect

Audi offers a broad choice of options for the new A6 allroad quattro. The head-up display projects important information onto the windshield. Ambient lighting bathes the interior with subtle LED light, and the widely adjustable deluxe front seats are optionally available with a ventilation and massage function. Additional highlights include four-zone automatic air conditioning, a panoramic glass roof and the convenience key, which can stay in the driver's jacket pocket.

Topping the modular range of infotainment options is the hard drive-based navigation system MMI Navigation plus with touchpad operation (MMI touch) and whole-word voice control. Its power-retractable eight-inch monitor displays extremely sharp, high-contrast images. The Bang & Olufsen Advanced Sound System boasts 15 speakers.

The new Audi A6 allroad quattro is also state of the art when it comes to connection technology. The optional Bluetooth car phone online connects it to the Internet via UMTS, and a WLAN hotspot lets the passengers surf and e-mail. Tailored services for the driver, such as the all-new Audi traffic information online or Audi music stream web radio, are delivered right to the car. Attractive services from Google, including Google Earth, Google Street View and voice-activated POI search, are also available.

Driver assistance systems

The Audi assistance and safety systems lend even more confidence to driving. The radar-based adaptive cruise control with stop & go function always keeps the new A6 allroad quattro at the proper distance from the car ahead. At speeds below 30 km/h (18.64 mph), the system initiates maximum braking in the event of an impending collision. ACC stop & go works closely together with the Audi pre sense safety system, which is available in a number of configurations.

Audi active lane assist helps the driver to maintain the lane; Audi side assist helps when changing lanes. The night vision assistant with marking of detected persons reduces the stress of driving in the dark. The driver information system with rest recommendation function detects when the driver is getting tired and recommends taking a rest.

A variety of high-end systems help take the stress out of parking. The park assist system with 360° display takes over the steering; the parking system plus with 360° camera provides good vision in all directions. Four small wide-angle cameras record images of the vehicle's immediate surroundings, which can then be displayed from a variety of perspectives on the MMI monitor.

Drivetrain

The new Audi A6 allroad quattro is available with a choice of four powerful and highly cultivated V6 engines - one TFSI gasoline engine and three TDI units. All are three-liter engines with turbocharging and direct injection. They make use of important technologies from the Audi modular efficiency platform - the start-stop system and innovative thermal management. Their fuel consumption has been reduced by as much as 20 percent compared with the previous model.

The 3.0 TFSI, which is boosted by a mechanically driven compressor, produces 228 kW (310 hp) and 440 Nm (324.53 lb-ft) of torque. It accelerates the Audi A6 allroad quattro from zero to 100 km/h (62.14 mph) in 5.9 seconds on the way to a electronically limited top speed of 250 km/h (155.34 mph). It consumes 8.9 liters of fuel per 100 km (26.43 US mpg).

The three variants of the 3.0 TDI produce 150 kW (204 hp), 180 kW (245 hp) and 230 kW (313 hp); torque values are 450, 580 and 650 Nm (331.90, 427.79 and 479.42 lb-ft). The entry-level version consumes on average just 6.1 liters of fuel per 100 km (38.56 US mpg), corresponding to 159 g CO2/km (255.89 g/mile). Audi will soon offer a particularly low-emissions clean diesel version of the 180 kW (245 hp) engine. The twin-turbo 3.0 TDI developing 230 kW (313 hp) is a powerful, great sounding engine. It accelerates the A6 allroad quattro from zero to 100 km/h (62.14 mph) in 5.6 seconds; the top speed is an electronically regulated 250 km/h (155.34 mph).

The most powerful TDI delivers its power to a smooth and fast-shifting eight-speed tiptronic transmission. The three other engines are paired with the seven-speed S tronic, a sporty dual-clutch transmission. With their wide ratio spreads, the automatic transmissions are major contributors to the efficiency of the Audi A6 allroad quattro. The driver can operate them manually, including via optional paddles on the steering wheel.

The quattro permanent four-wheel drive system is paired with torque vectoring. During dynamic driving this system brakes the wheels on the inside of the curve, which are under a reduced load, before they can slip. This further enhances traction and handling. The optional sport differential distributes the power in continuously variable proportions between the rear wheels.

Chassis

The chassis of the Audi A6 allroad quattro combines sportiness with comfort. The new electromechanical power steering is sensitive and highly efficient. The optional dynamic steering adjusts the steering ratio to the speed driven.

With the Audi drive select system, the driver can vary the function of the steering, the air suspension, the gas pedal, the automatic transmission, the sport differential, the automatic air conditioning, the lighting and the adaptive cruise control. In Efficiency mode, these systems work as economically as possible; their function can be very freely configured in Individual mode.

The adaptive air suspension, which combines air suspension with controlled damping, comes as standard. It lowers the body by 15 millimeters (0.59 in) at high speed and raises it by 35 millimeters (1.38 in) at the push of a button. This allroad mode is suitable for rough terrain. Furthermore, the driver can select a lift mode at low speeds. An additional ten millimeters (0.39 in) enables the new Audi A6 allroad quattro to also handle major irregularities in the road surface.

The Audi A6 allroad quattro rolls on 18-inch, five-arm alloy wheels and 235/55-size tires. Audi and quattro GmbH offer optional wheels measuring 18, 19 and 20 inches in diameter. The large brakes provide powerful deceleration. The driver can activate a hill descent assist function for steep downhill passages. This limits the speed to between 10 and 20 km/h (6.21 and 12.43 mph), depending on the surface.

The new Audi A6 allroad quattro will be available in Germany from spring 2012. The 3.0 TDI developing 150 kW (204 hp) has a list price of €54,600.

Audi A1 quattro

The Audi A1 quattro is powered by the 2.0 TFSI engine. The 1,984 cc, four-cylinder engine combines gasoline direct injection with turbocharging in the classic Audi manner. Among its highlights are the adjustable intake cam shaft and the two balance shafts, which ensure smooth operation. Maximum torque of 350 Nm (258.15 lb-ft) is continuously available between 2,500 and 4,500 rpm, and peak power (188 kW/256 hp) is developed at 6,000 rpm.

Every detail of the sporty, sonorous four-cylinder engine has been optimized for high performance and low fuel consumption. Common rail injection, a turbocharger with intercooler and a regulated oil pump are just a few examples. The Audi A1 quattro is expected to consume on average less than 8.5 liters of fuel per 100 km (27.67 US mpg). Yet it performs like a top-notch sports car: The standard sprint takes just 5.7 seconds, and top speed is 245 km/h (152.24 mph).

The 2.0 TFSI delivers its power to the quattro permanent all-wheel drive system via a precisely shifting six-speed transmission, bringing Vorsprung durch Technik to the small-car class. The heart of this system is an electronically controlled, hydraulically actuated multi-plate clutch whose package of plates rotates in an oil bath.

During normal driving, the clutch sends most of the engine's power to the front wheels. If traction decreases there, the clutch can transfer torque steplessly to the rear axle in just a few milliseconds by forcing the packages of plates together by a defined amount. A pressure reservoir helps the electric pump to develop the oil pressure. If a wheel on one of the axles should slip, it is braked by the electronic differential lock (EDL).

The placement of the multi-plate clutch at the rear axle provides for a harmonious distribution of the axle loads, and the chassis of the Audi A1 quattro has been adapted to the dynamics of the drivetrain. It is much more tautly tuned than that of the production model. The front suspension is a McPherson construction; a four-link axle is used at the rear. The sensitive and efficient electrohydraulic power steering has a sporty, direct 14.8:1 steering ratio.

The Audi A1 quattro rolls on 8.0 J x 18 cast alloy wheels. They are Glacier White, feature an exclusive turbine design and are fitted with 225/35-series tires. The internally vented front brake discs measure 312 millimeters (12.28 in) in diameter and are gripped by black calipers. The ESP stabilization program includes a sport mode and can be switched off entirely for a trip to the race track, for example.

One look is all it takes to see that the Audi A1 quattro is a very special vehicle. It is available only in Glacier White metallic, and its roof is painted high-gloss black. The front bumper is muscular, the frame and grate of the single-frame grille are high-gloss black. The curved bars in the headlights - the wings - are red. The grille, the roof arch and the rear hatch sport quattro badges.

The rear windows are tinted; the roof flows into a large, two-color wing. The color black accentuates the rear hatch and the diffuser. The LED rear lights are tinted; the rear bumper sports a distinctive look. The exhaust system terminates in two polished dual tailpipes on the left and the right, each measuring 100 millimeters (3.94 in) in diameter. The Audi A1 quattro is 3,987 millimeters (13.08 ft) long, 1,740 millimeters (5.71 ft) wide and 1,416 millimeters (4.65 ft) tall, making it somewhat longer than the model on which it is based. Luggage capacity is 210 liters (7.42 cu ft); folding down the rear seats increases this to 860 liters (30.37 cu ft).

Cool, sporty black dominates the interior of the Audi A1 quattro. The seats and the armrests on the doors are covered in Silk Nappa leather with contrasting red seams. The S sport seats up front have pronounced bolsters, integrated head restraints and a quattro badge on the backrest covers. The seats feature multi-way adjustment. The lower section of the center console shines in high-gloss black; the footrest and the pedal caps are made of brushed stainless steel. Red seams frame the floor mats, and the door sill trims bear A1 quattro badges.

The instrument cluster has a number of eye-catching features, including white needles, a red tachometer, the quattro logo and the color display for the driver information system. The multifunction sport steering wheel is flattened at the bottom, wrapped in leather with contrasting red stitching and sports the car's serial number. The shift lever knob is made of aluminum. Many control elements have an aluminum-look finish.

The Audi A1 quattro will be available from the second half of 2012 and will be supplied to customers with a full range of equipment. It includes many features taken directly from the luxury class, including xenon plus headlights, high-beam assistant, adaptive brake lights, LED interior lighting package, light and rain sensor, automatically dimming interior mirror, rear parking system, automatic air conditioning, alarm system, storage package, convenience key and cruise control.

The infotainment equipment likewise leaves nothing to be desired. It includes a CD changer, a digital radio tuner, the Audi music interface and MMI navigation plus. The Bose sound system drives 14 speakers with 465 watts of power; the woofers in the doors are indirectly lit with light guide LEDs. Audi connect uses the Bluetooth online car phone to connect to the Internet and deliver special web services, including Google Earth, to the car. Passengers can also connect their mobile devices to the integrated WLAN hotspot.

Audi A4 Avant

A bestseller has become even more attractive: Audi has updated the A4 series. New solutions for efficiency, driving dynamics and infotainment, along with an even more attractive design, attest the "Vorsprung durch Technik" achieved by the A4 Sedan, the A4 Avant, the A4 allroad quattro and the S4.
Design
The A4 is Audi's bestseller - for 39 years now and in its eighth generation. The brand has sold ten million such models in total. The Audi A4, with its elegance, sportiness and emotional appeal, forms the centerpiece of the Audi brand. And now the design has become even more clearly defined and striking in all models - the Sedan, the Avant, the allroad quattro and the S4.

The new look further accentuates the horizontal lines at the front end. The engine hood is more arched, the upper corners of the single frame grille are tapered, and the cross ribs and the Audi rings are highlighted three-dimensionally. The grille is painted gray, with high-gloss black on the six-cylinder models or in combination with the S line exterior package. The redesigned bumpers are striking with their angular air inlets, their revised grilles and the flat front fog lights. The Audi A4 allroad quattro is distinguished by its grille's horizontal chrome applications and by the round fog lights.

The Audi A4 allroad quattro is distinguished by its grille's horizontal chrome applications and by the round fog lights.
The headlights have also changed, with a slight wave at the bottom edges, and a re-arranged interior. Xenon plus headlights are available from Audi on request. The LED daytime running lights form a narrow, optically homogeneous band that remains open in the vicinity of the xenon lens. The adaptive light together with dynamic and static cornering lights are available on request.
The tail lights reflect the shape of the headlights, and in combination with xenon plus have homogeneous strips of LEDs. The bumper with its diffuser insert has been redesigned, with the exhaust system always terminating in two tailpipes.
There is a selection of 15 paint finishes, including four new tones. The Sedan and the Avant offer the S line exterior package, while the Avant also includes a roof spoiler.
The modifications have changed the dimensions only by a few millimeters. The Audi A4 Sedan and the Avant each have a length of 4.70 meters (15.42 ft), while the A4 allroad quattro and the S4 are 4.72 meters (15.49 ft) long. The wheelbases for all models are 2.81 meters (9.22 ft), and the width is 1.83 and 1.84 meters, respectively (6.0 and 6.04 ft). The height varies between 1.41 and 1.50 meters (4.63 and 4.92 ft) depending on the body version.
Interior
The interior of the Audi A4 models has also been refined. Audi offers a wide selection of new steering wheels with chrome and high-gloss inlays, with the leather sport steering wheel also featuring a flattened lower rim. The steering arm and the ignition key have been modified. High-gloss applications and the slender chrome trim at the controls add elegance to the interior.
The elaborate finish makes operation even simpler and more intuitive. The MMI navigation plus system now features four instead of eight buttons, with a script function integrated in the volume control dial. Other improvements concern operation of the automatic transmission, the efficient air conditioning systems, Audi drive select and the multifunction steering wheel. The seat heating and air conditioning are now directly operated at the respective buttons.

The high level of workmanship is as much a matter of course for Audi as a sure touch in the range of colors. All interior colors - except black - have been re-coordinated. The upholstery range has also been revised, with Fine Nappa leather replacing Valcona leather. The new, single-part cluster trim has been adapted in color to the interior, while the inlays are available in Aluminum Trigon, walnut dark brown and fine grain ash natural. Especially eye-catching is the Beaufort oak plywood inlay.
The interior of the S line sport package comes in black, refined with high-quality applications. 18-inch wheels or the optional 19-inch wheels and an S line sport suspension that lowers the body by 30 millimeters (1.18 in) complete the package. Audi exclusive and Audi exclusive line offer further individualized options.
The Audi A4 Sedan's luggage compartment still has its 480-liter capacity - 962 liters with the rear seats folded down (16.95 and 33.97 cubic ft). The A4 Avant and the A4 allroad quattro have 490 and 1,430 liters, respectively (17.30 and 50.50 cubic ft), with Audi offering an optional electrically operated tailgate for both models.
Engines
The new Audi A4's drive system sets new standards. The consumption levels have dropped by 11 percent on average, despite the increased power and torque of many of the engines. In the Sedan and the Avant each, Audi offers any of six TDI and four gasoline engines, with 23 possible engine-transmission combinations. All engines are supercharged direct-injection systems; the start-stop system and the recuperation system are standard throughout.
The TDI engines combine pulling power with pioneering efficiency, with the four-cylinder versions presenting extensive modifications. A new centrifugal pendulum-type absorber (in the 2.0 TDI with 100 kW, 120 kW or 130 kW with quattro drive) in the dual-mass flywheel makes engine running even more refined and quieter at low revs, for even earlier upshifting and savings of up to 0.2 liters per 100 km.
The most economical variant in the model family is the Audi A4 2.0 TDI with 100 kW (136 hp). In the Sedan, this engine needs only 4.2 liters of fuel per 100 km (56.0 US mpg) on average - a CO2 equivalent of just 112 grams per km (180.25 g/mile). The new A4 2.0 TDI with 120 kW (163 hp), also optimized for maximum efficiency, manages with 4.4 liters of diesel per 100 km (53.46 US mpg). This equates to 115 grams CO2 per km (185.07 g/mile). Both engines are available for the Sedan and the Avant.
In addition, three other four-cylinder diesel engines are available - with 88 kW (120 hp), 105 kW (143 hp) and 130 kW (177 hp). They can also be ordered for the allroad quattro, apart from the entry-level version. Three V6 TDI units complete the line. The 3.0 TDI with 150 kW (204 hp) (not for the allroad quattro) is the most efficient six-cylinder engine in its class worldwide; in the A4 Sedan it consumes an average of just 4.9 liters of fuel per 100 km (48.0 US mpg). The second variant, the 3.0 TDI, generates 180 kW (245 hp), with an especially clean diesel version.
The Audi A4 series also presents the latest state of the art in gasoline engine technology. A new highlight of the TFSI family is the new 1.8-liter engine, available for the Sedan and the Avant. The four-cylinder engine delivers sporty thrust, with a power output of 125 kW (170 hp) and 320 Nm (236.02 lb-ft) of torque. The average consumption in the Audi A4 Sedan is limited to 5.6 liters per 100 km (42.0 US mpg), or 134 grams CO2 per km (215.65 g/mile). That is a decrease in consumption of 19 percent compared with the predecessor engine.
The new 1.8 TFSI engine features many innovations: in the control of its valves and their lift, in the novel thermal management system, in the fuel injection system, in the turbocharger and in the integration of the exhaust manifold in the cylinder head. The engine weighs 3.5 kilograms (7.72 lb) less and its internal friction has sharply decreased.
The entry-level gasoline engine is the 1.8 TFSI with 88 kW (120 hp). The 2.0 TFSI - as the only spark-ignition engine also available in the Audi A4 allroad quattro - delivers 155 kW (211 hp). At the top of the line is the 3.0 TFSI in two variants. In the Audi A4 the V6, to follow a bit later, affords 200 kW (272 hp). In the sporty Audi S4 top model its power is an impressive 245 kW (333 hp).
Drivetrain
The wide range of drivetrains is typical of Audi. A six-speed manual transmission is standard on the Sedan and Avant models with front-wheel drive; most variants offer continuously variable multitronic as an option. The quattro versions have either the manual transmission or (as of the 2.0 TDI with 130 kW (177 hp)) the seven-speed S tronic on board. The Audi A4 allroad quattro employs a manual transmission or S tronic with all engine versions.
The innovative thermal management system shortens the warm-up phase of the manual transmission, among other things, and thereby reduces friction loss. All transmissions are distinguished by convenient and precise operation, high efficiency and a wide spread of gear ratios - the long ratios in the higher gears reduces fuel consumption, while the short ratios in the lower gears benefit the dynamics.
The quattro permanent all-wheel drive is standard on the Audi A4 allroad quattro, and available in the Sedan and Avant from the 2.0 TDI with 105 kW (143 hp). The A4 family uses the self-locking center differential here. In regular driving operation it primarily transmits the engine torque to the rear wheels in the ratio of 40 to 60. If necessary, redistribution occurs within the shortest possible time. The torque vectoring function supplements the work of the center differential with finely incremented brake applications, to make handling even more precise and safer.
In the V6 quattro variants Audi offers the sport differential as a supplement, lending maximum precision and high traction to the A4 when cornering at the handling limits. The high-end component actively distributes the power between the rear wheels as required.
Chassis
The chassis of the Audi A4 is striking with its sporty precision, high ride comfort and superior safety. The mounts of the rear suspension control arms and the characteristics of the shock absorbers have been even more finely tuned. Most of the components of the five-link front suspension and the trapezoidal-link rear suspension are made of aluminum.
The electromechanical power steering is new in all models of the series. The direct gear ratios convey precise road contact; slight brake applications counteract pulling to the side on unevenly slippery surfaces. The electromechanical power steering requires no energy for straight-ahead motion, thereby reducing fuel consumption by up to 0.3 liters per 100 km. This is equivalent to a reduction in CO2 emissions of up to 7 g/km (11.27 g/mile).
Another high-end feature that gives the Audi A4 a special status in its class is Audi drive select. In the basic package, the driver can switch the characteristic of the accelerator, the shift points of the automatic transmission, the power steering and the automatic air conditioning between the four modes "comfort," "auto," "dynamic" and "efficiency." If there is an onboard navigation system, the additional "individual" mode is also included.
Further modules are optional - adaptive cruise control or the cruise control system, the sport differential, the suspension with damper control and dynamic steering. By means of a superposition gear, the gear ratio is adjusted in a continuously variable manner depending on the driven speed; at the handling limits small interventions compensate for understeering and oversteering.
All front-wheel-drive versions of the Audi A4 feature the electronic stabilization program (ESP) with electronic limited slip differential. In dynamic driving the system further improves handling and safety by initiating minimum brake interventions at the front wheel that is subject to a reduced load on the inside of the curve. The large wheel brakes - with ventilated front and rear disks in many variants - offer excellent stopping power and can be precisely modulated.
All Audi A4 variants roll off the assembly line on elegant aluminum wheels. Depending on the engine version, they are 16 or 17 inches in size; tires with optimized rolling resistance belong to the 205/60 and 225/50 series. The A4 3.0 TFSI has 18-inch wheels with 245/40 series tires. The line of options ranges to 19 inches with 255/35 series tires. Four of the 18 available wheels are new designs. The A4 allroad quattro offers four independent designs.
Assistance systems
Audi offers highly developed assistance systems for the A4 family, for making driving even more relaxed. Standard on all variants is the new driver information system with break recommendation - it detects and draws the driver's attention to deviations from typical driving behavior on the basis of steering motions and other parameters.
The adaptive cruise control assistance system keeps the Audi A4 at a constant distance from the preceding vehicle at speeds between zero and 200 km/h (124.27 mph). If the threat of a rear-end collision becomes imminent at speeds below 30 km/h (18.64 mph), the system will execute a full brake application. Audi active lane assist supports the driver in keeping to his lane. A camera detects the lane markings and the system makes slight corrections to the steering if necessary. Audi side assist monitors the space behind the Audi A4 by radar and detects any vehicles in the blind spot, for example.
Infotainment systemsAudi offers a whole kit of state-of-the-art infotainment systems for its A4 series. The chorus CD radio with eight speakers is standard, while the MMI navigation plus system with large hard disk, color monitor, 3D graphics and DVD player forms the top of the line. Voice control and the optional digital audio broadcasting are further improvements to the system.
The high-end supplement to the MMI navigation plus system is the Bluetooth online car phone. Via Audi connect the system provides special services in the car, such as voice-controlled Google searches for points of interest and navigation with Google Earth pictures, along with Google Street View. Audi online traffic information, another such service, gives the driver the latest news on congestion along the selected route. The WLAN hotspot, another feature of the Bluetooth online car phone, allows passengers in the Audi A4 to surf the internet and send e-mails as they please with their mobile devices.
The Audi S4
The Audi S4, available in the Sedan and Avant versions, employs the most powerful engine in the line - the 3.0 TFSI with 245 kW (333 hp) and 440 Nm (324.53 lb-ft) torque. The Sedan's average fuel consumption is a mere 8.0 liters per 100 km (29.40 US mpg) - with an impressive performance: The Audi S4 accelerates in 5.0 seconds from zero to 100 km/h (62.14 mph) and achieves an electronically limited maximum speed of 250 km/h (155.34 mph).
The modified Audi S4 is identifiable from the changes to the headlights, the bumpers, the air inlets and colors. The interior also contains subtle changes in appearance. The S sport suspension and 18-inch wheels featured on the S4 deliver outstanding road grip.
Prices
The prices of the A4 have changed only slightly, despite the extensive upgrading. For example, the Audi A4 2.0 TFSI costs just 475 euros more - the sporty Sedan is now listed at 35,425 euros.

Audi S4

A bestseller has become even more attractive: Audi has updated the A4 series. New solutions for efficiency, driving dynamics and infotainment, along with an even more attractive design, attest the "Vorsprung durch Technik" achieved by the A4 Sedan, the A4 Avant, the A4 allroad quattro and the S4.

The interior of the Audi A4 models has also been refined. Audi offers a wide selection of new steering wheels with chrome and high-gloss inlays, with the leather sport steering wheel also featuring a flattened lower rim. The steering arm and the ignition key have been modified. High-gloss applications and the slender chrome trim at the controls add elegance to the interior.
The elaborate finish makes operation even simpler and more intuitive. The MMI navigation plus system now features four instead of eight buttons, with a script function integrated in the volume control dial. Other improvements concern operation of the automatic transmission, the efficient air conditioning systems, Audi drive select and the multifunction steering wheel. The seat heating and air conditioning are now directly operated at the respective buttons.
The high level of workmanship is as much a matter of course for Audi as a sure touch in the range of colors. All interior colors - except black - have been re-coordinated. The upholstery range has also been revised, with Fine Nappa leather replacing Valcona leather. The new, single-part cluster trim has been adapted in color to the interior, while the inlays are available in Aluminum Trigon, walnut dark brown and fine grain ash natural. Especially eye-catching is the Beaufort oak plywood inlay.
The interior of the S line sport package comes in black, refined with high-quality applications. 18-inch wheels or the optional 19-inch wheels and an S line sport suspension that lowers the body by 30 millimeters (1.18 in) complete the package. Audi exclusive and Audi exclusive line offer further individualized options.
The Audi A4 Sedan's luggage compartment still has its 480-liter capacity - 962 liters with the rear seats folded down (16.95 and 33.97 cubic ft). The A4 Avant and the A4 allroad quattro have 490 and 1,430 liters, respectively (17.30 and 50.50 cubic ft), with Audi offering an optional electrically operated tailgate for both models.
Engines
The new Audi A4's drive system sets new standards. The consumption levels have dropped by 11 percent on average, despite the increased power and torque of many of the engines. In the Sedan and the Avant each, Audi offers any of six TDI and four gasoline engines, with 23 possible engine-transmission combinations. All engines are supercharged direct-injection systems; the start-stop system and the recuperation system are standard throughout.
The TDI engines combine pulling power with pioneering efficiency, with the four-cylinder versions presenting extensive modifications. A new centrifugal pendulum-type absorber (in the 2.0 TDI with 100 kW, 120 kW or 130 kW with quattro drive) in the dual-mass flywheel makes engine running even more refined and quieter at low revs, for even earlier upshifting and savings of up to 0.2 liters per 100 km.

The most economical variant in the model family is the Audi A4 2.0 TDI with 100 kW (136 hp). In the Sedan, this engine needs only 4.2 liters of fuel per 100 km (56.0 US mpg) on average - a CO2 equivalent of just 112 grams per km (180.25 g/mile). The new A4 2.0 TDI with 120 kW (163 hp), also optimized for maximum efficiency, manages with 4.4 liters of diesel per 100 km (53.46 US mpg). This equates to 115 grams CO2 per km (185.07 g/mile). Both engines are available for the Sedan and the Avant.
In addition, three other four-cylinder diesel engines are available - with 88 kW (120 hp), 105 kW (143 hp) and 130 kW (177 hp). They can also be ordered for the allroad quattro, apart from the entry-level version. Three V6 TDI units complete the line. The 3.0 TDI with 150 kW (204 hp) (not for the allroad quattro) is the most efficient six-cylinder engine in its class worldwide; in the A4 Sedan it consumes an average of just 4.9 liters of fuel per 100 km (48.0 US mpg). The second variant, the 3.0 TDI, generates 180 kW (245 hp), with an especially clean diesel version.
The Audi A4 series also presents the latest state of the art in gasoline engine technology. A new highlight of the TFSI family is the new 1.8-liter engine, available for the Sedan and the Avant. The four-cylinder engine delivers sporty thrust, with a power output of 125 kW (170 hp) and 320 Nm (236.02 lb-ft) of torque. The average consumption in the Audi A4 Sedan is limited to 5.6 liters per 100 km (42.0 US mpg), or 134 grams CO2 per km (215.65 g/mile). That is a decrease in consumption of 19 percent compared with the predecessor engine.
The new 1.8 TFSI engine features many innovations: in the control of its valves and their lift, in the novel thermal management system, in the fuel injection system, in the turbocharger and in the integration of the exhaust manifold in the cylinder head. The engine weighs 3.5 kilograms (7.72 lb) less and its internal friction has sharply decreased.
The entry-level gasoline engine is the 1.8 TFSI with 88 kW (120 hp). The 2.0 TFSI - as the only spark-ignition engine also available in the Audi A4 allroad quattro - delivers 155 kW (211 hp). At the top of the line is the 3.0 TFSI in two variants. In the Audi A4 the V6, to follow a bit later, affords 200 kW (272 hp). In the sporty Audi S4 top model its power is an impressive 245 kW (333 hp).
Drivetrain
The wide range of drivetrains is typical of Audi. A six-speed manual transmission is standard on the Sedan and Avant models with front-wheel drive; most variants offer continuously variable multitronic as an option. The quattro versions have either the manual transmission or (as of the 2.0 TDI with 130 kW (177 hp)) the seven-speed S tronic on board. The Audi A4 allroad quattro employs a manual transmission or S tronic with all engine versions.
The innovative thermal management system shortens the warm-up phase of the manual transmission, among other things, and thereby reduces friction loss. All transmissions are distinguished by convenient and precise operation, high efficiency and a wide spread of gear ratios - the long ratios in the higher gears reduces fuel consumption, while the short ratios in the lower gears benefit the dynamics.
The quattro permanent all-wheel drive is standard on the Audi A4 allroad quattro, and available in the Sedan and Avant from the 2.0 TDI with 105 kW (143 hp). The A4 family uses the self-locking center differential here. In regular driving operation it primarily transmits the engine torque to the rear wheels in the ratio of 40 to 60. If necessary, redistribution occurs within the shortest possible time. The torque vectoring function supplements the work of the center differential with finely incremented brake applications, to make handling even more precise and safer.
In the V6 quattro variants Audi offers the sport differential as a supplement, lending maximum precision and high traction to the A4 when cornering at the handling limits. The high-end component actively distributes the power between the rear wheels as required.
Chassis
The chassis of the Audi A4 is striking with its sporty precision, high ride comfort and superior safety. The mounts of the rear suspension control arms and the characteristics of the shock absorbers have been even more finely tuned. Most of the components of the five-link front suspension and the trapezoidal-link rear suspension are made of aluminum.
The electromechanical power steering is new in all models of the series. The direct gear ratios convey precise road contact; slight brake applications counteract pulling to the side on unevenly slippery surfaces. The electromechanical power steering requires no energy for straight-ahead motion, thereby reducing fuel consumption by up to 0.3 liters per 100 km. This is equivalent to a reduction in CO2 emissions of up to 7 g/km (11.27 g/mile).
Another high-end feature that gives the Audi A4 a special status in its class is Audi drive select. In the basic package, the driver can switch the characteristic of the accelerator, the shift points of the automatic transmission, the power steering and the automatic air conditioning between the four modes "comfort," "auto," "dynamic" and "efficiency." If there is an onboard navigation system, the additional "individual" mode is also included.
Further modules are optional - adaptive cruise control or the cruise control system, the sport differential, the suspension with damper control and dynamic steering. By means of a superposition gear, the gear ratio is adjusted in a continuously variable manner depending on the driven speed; at the handling limits small interventions compensate for understeering and oversteering.
All front-wheel-drive versions of the Audi A4 feature the electronic stabilization program (ESP) with electronic limited slip differential. In dynamic driving the system further improves handling and safety by initiating minimum brake interventions at the front wheel that is subject to a reduced load on the inside of the curve. The large wheel brakes - with ventilated front and rear disks in many variants - offer excellent stopping power and can be precisely modulated.
All Audi A4 variants roll off the assembly line on elegant aluminum wheels. Depending on the engine version, they are 16 or 17 inches in size; tires with optimized rolling resistance belong to the 205/60 and 225/50 series. The A4 3.0 TFSI has 18-inch wheels with 245/40 series tires. The line of options ranges to 19 inches with 255/35 series tires. Four of the 18 available wheels are new designs. The A4 allroad quattro offers four independent designs.
Assistance systems
Audi offers highly developed assistance systems for the A4 family, for making driving even more relaxed. Standard on all variants is the new driver information system with break recommendation - it detects and draws the driver's attention to deviations from typical driving behavior on the basis of steering motions and other parameters.
The adaptive cruise control assistance system keeps the Audi A4 at a constant distance from the preceding vehicle at speeds between zero and 200 km/h (124.27 mph). If the threat of a rear-end collision becomes imminent at speeds below 30 km/h (18.64 mph), the system will execute a full brake application. Audi active lane assist supports the driver in keeping to his lane. A camera detects the lane markings and the system makes slight corrections to the steering if necessary. Audi side assist monitors the space behind the Audi A4 by radar and detects any vehicles in the blind spot, for example.
Infotainment systemsAudi offers a whole kit of state-of-the-art infotainment systems for its A4 series. The chorus CD radio with eight speakers is standard, while the MMI navigation plus system with large hard disk, color monitor, 3D graphics and DVD player forms the top of the line. Voice control and the optional digital audio broadcasting are further improvements to the system.
The high-end supplement to the MMI navigation plus system is the Bluetooth online car phone. Via Audi connect the system provides special services in the car, such as voice-controlled Google searches for points of interest and navigation with Google Earth pictures, along with Google Street View. Audi online traffic information, another such service, gives the driver the latest news on congestion along the selected route. The WLAN hotspot, another feature of the Bluetooth online car phone, allows passengers in the Audi A4 to surf the internet and send e-mails as they please with their mobile devices.
The Audi S4
The Audi S4, available in the Sedan and Avant versions, employs the most powerful engine in the line - the 3.0 TFSI with 245 kW (333 hp) and 440 Nm (324.53 lb-ft) torque. The Sedan's average fuel consumption is a mere 8.0 liters per 100 km (29.40 US mpg) - with an impressive performance: The Audi S4 accelerates in 5.0 seconds from zero to 100 km/h (62.14 mph) and achieves an electronically limited maximum speed of 250 km/h (155.34 mph).
The modified Audi S4 is identifiable from the changes to the headlights, the bumpers, the air inlets and colors. The interior also contains subtle changes in appearance. The S sport suspension and 18-inch wheels featured on the S4 deliver outstanding road grip.
Prices
The prices of the A4 have changed only slightly, despite the extensive upgrading. For example, the Audi A4 2.0 TFSI costs just 475 euros more - the sporty Sedan is now listed at 35,425 euros.
