- Limited-production, top-of-the-line version of the high performance sports car
- 100 pounds lighter, the carbon body parts
- V10 FSI with 412 kW (560 hp), 0-100 km / h in 3.6 seconds
Ingolstadt, now even stronger, lighter and faster: displays the version of the Audi R8's limited production high performance sports cars, GT R8. Output from the 5.2-liter V10 has been increased to 412 kW (560 hp), vehicle weight has been reduced by approximately 100 kilograms (£ 220.46). GT R8 accelerates from zero to 100 km / h (62.14 mph) in 3.6 seconds and reaches a top speed of 320 km / h (198.84 mph).
The R8 high-performance sports cars have a winner from scratch. This applies to both the production model, winner of the "World Performance Car" Award in 2008 (R8) and in 2010 (R8 V10), and racing cars, with the LMS R8, which won 23 races in his first season and claimed three championships. The genes from the version now comes to road races - the GT R8. Exclusive series limited to 333 units. Every GT R8 has a badge with a production number on the shift key lever.
Consistent use of lightweight construction: 100 kilograms (220.46 pounds), trimmed
production R8 5.2 FSI quattro has been a successful example of Audi's lightweight construction philosophy. Its aluminum Audi Space Frame (ASF) body weighs just 210 kilograms (462.97 pounds). aluminum body panels joined to the frame with extruded profiles and cast nodes through a positive and frictional connection. Machine framework is made of ultra lightweight magnesium.
ASF body largely hand-built at the Neckarsulm factory complex in the manufacturing process. Very high strength body is the basis for the proper handling of high-performance sports cars, and also offer good comfort and safety first class crash vibration.
Thanks to ASF body, the production R8 5.2 FSI quattro weighs only 1625 kilograms (3,582.51 lb) - with all-wheel drive quattro permanent and optional R Tronic transmission. This makes it all the more difficult for the engineers to once again achieve substantial weight savings. They took a complicated approach that involves every aspect of vehicle, and eventually came to rest in the scales 1 525 kilograms (3,362.05 lb).
R8 GT windshield made of thinner glass, while the cell bulkhead between the passenger and engine compartments, and windows in the rear doors are made of strong, lightweight polycarbonate. All three modifications are saved nine kilograms (19.84 pounds). Rear wing is still good for an additional 1.2 kilograms (2.65 pounds); thin sheets of metal and pieces of shaved additional 2.6 kilograms (5.73 pounds) of aluminum hatch for containers 100 liters (3.53 cubic feet) baggage at the front of the car.
Long rear hatch is made of carbon fiber reinforced plastic (CFRP) - a gain of 6.6 kilograms (14.55 pounds). And the rear bumper of the same material sideblades save an additional 5.2 and 1.5 kilograms (11.46 and 3.31 pounds), respectively. With minimal weight and high strength, CFRP is an ideal material for a high-performance sports car, and Audi has extensive expertise in its use.
The engineers are also striving to shave every possible gram of weight of the technical components of R8. They shaved one kilogram (2.20 pounds) from the power brake system, four kilograms (8.82 pounds) of aluminum cap from the brake discs and 9.4 kilograms (20.72 pounds) of batteries. The engineers also found 2.3 kilograms (5.07 pounds) of air intake modules and 2.8 kilograms (6.17 pounds) in isolation of the engine compartment.
interior is also great potential to save weight-savings. The new, lightweight carpets account for 7.9 kilograms (17.42 lb) bucket seats with a chassis, glass reinforced plastic (GRP) account for 31.5 kilograms (69.45 pounds). Detailed a number of additional steps that targeted the interior, exterior and technology, such as a higher class, for mild steel exhaust system tailpipes.
Even sharper and more effective: design
Audi R8 GT design is an expression of concentrated power - a beautiful, technical statue measuring 4.43 meters (14.53 feet) long, 1.93 meters (6.33 feet) wide and only 1.23 meters (4.04 feet) high . It suffered a lot of exterior modifications that further refine the appearance. Many of them also reduce weight and improve aerodynamics. R8 generates more downforce GT when compared with the rapid production model driven - without an increase in the value of Cd (0.36) or the frontal region (1.99 m2) (21.42 square feet).
From single-frame grille frames, struts and blades in the air intake finished in matt titanium gray; matt black painted grille. The splitter below the bumper has a double lip and made of carbon. Slender, curved flics on the corner of the nose to increase downforce on the front axle and also made of carbon fiber composites.
One highlight of the R8 GT is standard LED lamps, the use of light emitting diodes for all functions. They produce bright, uniform light, has a long service life and low energy consumption. Lighting also has an attractive and distinctive appearance. Daytime running lights each consist of 24 LEDs and appear as a continuous band. The reflectors are reminded open clam shells.
Defining element of the display is sideblades, which direct air to the engine in the R8 and GT also made of carbon matte. The same materials used for housing to reduce the size of the side mirror mounted on aluminum base. 19-inch wheels feature an exclusive design of twin five-spoke Y in titanium-look finish. Sport front fender "GT" badges.
Modifications to the back of the car is very obvious, beginning with a fixed-wing carbon matte. ventilation curtains at either side of the rear door and bumper CFRP, which integrates a large circular tailpipes, and vents to the wheel wells, have been redesigned. Larger diffuser is made of carbon fiber composites, panels and license plates in the back of the blade width in matte gray titanium. Its tail lights, which also uses LED technology, has been housing the dark with clear glass panels.
Audi R8 GT offers a choice of four body colors: Orange Metallic Samoa, Suzuka Gray Metallic, Silver Ice Metallic Phantom Black pearl effect and
Breathtakingly powerful: with 412 kW (560 hp), 5.2 FSI
The V10 is modified, which includes the cylinder head is painted red, Audi R8 provides the GT performance of the heart. The sprint GT R8 from start up to highway speed in 3.6 seconds and from zero to 200 km / h (124.27 mph) in 10.8 seconds. And encourages not leave until the top speed of 320 km / h (198.84 mph) is reached.
Changes to the electronic engine coaxed an extra 26 kW of cylinder-ten, which now produces 412 kW (560 hp) from a displacement of 5204 cc. Torque curve peaks at 540 Nm (398.28 pounds-ft) at 6,500 rpm, 10 Nm (£ 7.38-ft) is more than the production version. This V10 has a specific power output of 79.2 kW (107.6 hp) per liter displacement. power-to-weight ratio is 3.70 kilograms (8.16 pounds) per kW, or 2.72 kg (6.00 pounds) per-hp. The engine redlines at 8700 rpm.
Long-stroke engine (bore x stroke 84.5 x 92.8 mm [3.33 x 3.65 in]), which was built in hand-factory in Győr, Hungary, features crankcase made of aluminum-silicon alloys are lightweight and excellent strength. A bedplate - a frame for the crankshaft bearing bridge - further increase its stiffness. Complete engine weighs just 258 kilograms (568.79 pounds). This is marked with a cylinder angle of 90 degrees and dry lubrication-bah, which uses a highly efficient oil pump module. Both solutions reduce the center of gravity and thus improve driving dynamics.
crankshaft is designed as a pivot pin general. Which connects the piston rod opposite the crankpin involving public, resulting in the firing intervals alternately 54 and 90 degrees. This unique rhythms provide an attractive V10 sound - music, very technical grand like that in racing. Two flaps in the exhaust system and tone adjust the volume as a function of engine speed and load.
Normally aspirated engines consume an average of 13.7 liters of fuel per 100 km (17.17 U.S. mpg) - fuel economy very good given extraordinary powers. FSI petrol direct injection system injects fuel into the combustion chamber up to 120 bar pressure. Turbulent mixture cool the cylinder wall, allowing the compression ratio of 12.5:1. A variable intake manifold and continuous adjustment of the chain-driven camshaft ensures that the combustion chamber is fully filled. Flaps in the intake ports to facilitate the formation of the mixture by pushing the movement in the air falling revenues.
The drivetrain: uncompromising traction
Gear changes in the GT R8 is handled by the R Tronic sequential manual transmission. Electrohydraulic clutch and switching units receive their orders electronically. It changes gear faster than the six-skilled driver can - in a tenth of a second at high loads and engine speeds.
Electronic management system offers automatic with Sport mode and the characteristics of Normal, and two manual level. This is controlled using the gear selector lever briefly about the central tunnel and two paddles in the steering wheel. Maximum thrust when the launch is guaranteed by the Launch Control - a program that manages a full engine acceleration at high speed and minimum wheel slip when starting.
permanent quattro all-wheel-drive is an ideal technology for a high-performance sports car. Viscous clutch located in front of the center sends 15 percent of the difference in power to the front axle and 85 percent to the rear wheels during normal driving. This split harmonizes perfectly with 43:57 weight distribution which Audi R8 GT's per cent. clutch send as many as 30 percent of power to the front wheels in milliseconds, if necessary. A mechanical locking differential on the rear axle further improve traction. This provides a restriction to 25 percent when the acceleration and up to 40 percent in the attack.
Even tauter chassis and more precise
The Audi R8 high-performance GT sports car driving machine with a heart of lateral acceleration and lightning-fast, almost instantaneous reaction. mid-mounted engine is close to the vertical axis; mass almost negligible during the change of direction quickly. GT R8 is a dynamic, precise and stable in almost every situation.
This followed the racing chassis design classic - double wishbones made out of aluminum to find wheels. That is, hydraulic power-assisted rack-and-wing has a ratio 16.3:1 steering wheel connects the driver directly and intimately and exactly the road. A manually adjustable coilover suspension, which lowers the body as much as 10 millimeters (0.39 in), is standard. a higher front and rear wheel camber make the level of infestation is more agile handling than the standard model.
Forged 19-inch wheels 8.5 J x 19 front and 11 J x 19 at the rear, and shod with size 235/35 and 295/30 tires, respectively. Audi 305/30 tires will increase along with the optional wheels on the rear axle on demand. Cup tires, which offer the ultimate in performance on dry roads, is available for race fans.
Audi mountain internally ventilated, carbon fiber ceramic brake discs standard. They are extremely durable and abrasion resistance and especially light. Together they weight nine kilograms (19.84 pounds) less than their steel counterparts of the same size. They measure 380 mm (14.96 in) in diameter in front and 356 mm (14.02 in) at the rear. Who fled to the friction ring helmets through elastic elements. Red brake calipers anodized aluminum - with six pistons at the front - which is exclusive to the GT R8.
ESP stabilization program specifically for the GT R8 and can switch to Sport mode simply by pressing a button to allow spectacular, but safe, oversteer when accelerating out of corners. The driver can deactivate the system fully for the trip to the race track.
Exclusive and dynamic: the interior and equipment
At Audi, reducing weight means better performance and efficiency, but does not sacrifice. The Audi R8 GT, which sells Audi in Germany for € 193,000, is equipped with automatic climate control system and power windows, navigation system with MMI operating logic and a powerful sound system.

The new, lightweight carpets account for 7.9 kilograms (17.42 lb) bucket seats with a chassis, glass reinforced plastic (GRP) account for 31.5 kilograms (69.45 pounds). Detailed a number of additional steps that targeted the interior, exterior and technology, such as a higher class, for mild steel exhaust system tailpipes.
Even sharper and more effective: design
Audi R8 GT design is an expression of concentrated power - a beautiful, technical statue measuring 4.43 meters (14.53 feet) long, 1.93 meters (6.33 feet) wide and only 1.23 meters (4.04 feet) high . It suffered a lot of exterior modifications that further refine the appearance. Many of them also reduce weight and improve aerodynamics. R8 generates more downforce GT when compared with the rapid production model driven - without an increase in the value of Cd (0.36) or the frontal region (1.99 m2) (21.42 square feet).
From single-frame grille frames, struts and blades in the air intake finished in matt titanium gray; matt black painted grille. The splitter below the bumper has a double lip and made of carbon. Slender, curved flics on the corner of the nose to increase downforce on the front axle and also made of carbon fiber composites.
One highlight of the R8 GT is standard LED lamps, the use of light emitting diodes for all functions. They produce bright, uniform light, has a long service life and low energy consumption. Lighting also has an attractive and distinctive appearance. Daytime running lights each consist of 24 LEDs and appear as a continuous band. The reflectors are reminded open clam shells.
Defining element of the display is sideblades, which direct air to the engine in the R8 and GT also made of carbon matte. The same materials used for housing to reduce the size of the side mirror mounted on aluminum base. 19-inch wheels feature an exclusive design of twin five-spoke Y in titanium-look finish. Sport front fender "GT" badges.
Modifications to the back of the car is very obvious, beginning with a fixed-wing carbon matte. ventilation curtains at either side of the rear door and bumper CFRP, which integrates a large circular tailpipes, and vents to the wheel wells, have been redesigned. Larger diffuser is made of carbon fiber composites, panels and license plates in the back of the blade width in matte gray titanium. Its tail lights, which also uses LED technology, has been housing the dark with clear glass panels.
Audi R8 GT offers a choice of four body colors: Orange Metallic Samoa, Suzuka Gray Metallic, Silver Ice Metallic Phantom Black pearl effect and
Breathtakingly powerful: with 412 kW (560 hp), 5.2 FSI
The V10 is modified, which includes the cylinder head is painted red, Audi R8 provides the GT performance of the heart. The sprint GT R8 from start up to highway speed in 3.6 seconds and from zero to 200 km / h (124.27 mph) in 10.8 seconds. And encourages not leave until the top speed of 320 km / h (198.84 mph) is reached.
Changes to the electronic engine coaxed an extra 26 kW of cylinder-ten, which now produces 412 kW (560 hp) from a displacement of 5204 cc. Torque curve peaks at 540 Nm (398.28 pounds-ft) at 6,500 rpm, 10 Nm (£ 7.38-ft) is more than the production version. This V10 has a specific power output of 79.2 kW (107.6 hp) per liter displacement. power-to-weight ratio is 3.70 kilograms (8.16 pounds) per kW, or 2.72 kg (6.00 pounds) per-hp. The engine redlines at 8700 rpm.
Long-stroke engine (bore x stroke 84.5 x 92.8 mm [3.33 x 3.65 in]), which was built in hand-factory in Győr, Hungary, features crankcase made of aluminum-silicon alloys are lightweight and excellent strength. A bedplate - a frame for the crankshaft bearing bridge - further increase its stiffness. Complete engine weighs just 258 kilograms (568.79 pounds). This is marked with a cylinder angle of 90 degrees and dry lubrication-bah, which uses a highly efficient oil pump module. Both solutions reduce the center of gravity and thus improve driving dynamics.
crankshaft is designed as a pivot pin general. Which connects the piston rod opposite the crankpin involving public, resulting in the firing intervals alternately 54 and 90 degrees. This unique rhythms provide an attractive V10 sound - music, very technical grand like that in racing. Two flaps in the exhaust system and tone adjust the volume as a function of engine speed and load.
Normally aspirated engines consume an average of 13.7 liters of fuel per 100 km (17.17 U.S. mpg) - fuel economy very good given extraordinary powers. FSI petrol direct injection system injects fuel into the combustion chamber up to 120 bar pressure. Turbulent mixture cool the cylinder wall, allowing the compression ratio of 12.5:1. A variable intake manifold and continuous adjustment of the chain-driven camshaft ensures that the combustion chamber is fully filled. Flaps in the intake ports to facilitate the formation of the mixture by pushing the movement in the air falling revenues.
The drivetrain: uncompromising traction
Gear changes in the GT R8 is handled by the R Tronic sequential manual transmission. Electrohydraulic clutch and switching units receive their orders electronically. It changes gear faster than the six-skilled driver can - in a tenth of a second at high loads and engine speeds.
Electronic management system offers automatic with Sport mode and the characteristics of Normal, and two manual level. This is controlled using the gear selector lever briefly about the central tunnel and two paddles in the steering wheel. Maximum thrust when the launch is guaranteed by the Launch Control - a program that manages a full engine acceleration at high speed and minimum wheel slip when starting.
permanent quattro all-wheel-drive is an ideal technology for a high-performance sports car. Viscous clutch located in front of the center sends 15 percent of the difference in power to the front axle and 85 percent to the rear wheels during normal driving. This split harmonizes perfectly with 43:57 weight distribution which Audi R8 GT's per cent. clutch send as many as 30 percent of power to the front wheels in milliseconds, if necessary. A mechanical locking differential on the rear axle further improve traction. This provides a restriction to 25 percent when the acceleration and up to 40 percent in the attack.
Even tauter chassis and more precise
The Audi R8 high-performance GT sports car driving machine with a heart of lateral acceleration and lightning-fast, almost instantaneous reaction. mid-mounted engine is close to the vertical axis; mass almost negligible during the change of direction quickly. GT R8 is a dynamic, precise and stable in almost every situation.
This followed the racing chassis design classic - double wishbones made out of aluminum to find wheels. That is, hydraulic power-assisted rack-and-wing has a ratio 16.3:1 steering wheel connects the driver directly and intimately and exactly the road. A manually adjustable coilover suspension, which lowers the body as much as 10 millimeters (0.39 in), is standard. a higher front and rear wheel camber make the level of infestation is more agile handling than the standard model.

DETROIT, Mi., Jan 11, 2010 - Audi is showing an uncompromising purist compact sports car with all-electric drive at the first major auto show of 2010. The Detroit showcar Audi e-tron is the name of this 3.93 meter (154.72 in) long and 1.78 meter (70.08 in) wide but just 1.22 meter (48.03 in) tall two-seater; just a few months after the debut of the Audi e-tron at the 2009 Frankfurt Motor Show, this is now the second electric concept vehicle from the brand with the four rings.
Coupled with the Detroit showcar Audi e-tron’s low gross weight of around only 1,350 kilograms (2976.24 lb), high-torque power units driving the rear wheels guarantee commensurate road performance. Two electric motors
with a combined output of 150 kW (204 hp) and 2,650 Nm (1954.54 lb-ft) accelerate the coupe with ASF-design aluminum body from 0 to 100 km/h (62.14 mph) in just 5.9 seconds. The Audi e-tron accomplishes the sprint from 60 to 120 km/h (37.28 - 74.56 mph) in a mere 5.1 seconds.
The Detroit showcar Audi e-tron is able to distribute its electric motors’ high torque between the wheels entirely as required. Its “torque vectoring” is the key to a thrilling level of active precision and excellent traction. Thanks also to its low weight, short wheelbase and perfect weight distribution for dynamic handling, the Audi e-tron has all the drivability of a go-kart – agile, good on bends and neutral right up to the very high handling limit.
Lithium-ion batteries, located for an optimal center of gravity behind the passenger compartment and ahead of the rear axle, make an effective energy content of 45 kilowatt-hours available. This makes an operating range of up to 250 kilometers (155.34 miles) realistically possible.
As previously with the first e-tron concept car shown in Frankfurt, Audi again bases all components in this electric vehicle on an integral concept with many revolutionary details: a heat pump as an efficient means of heating up and maintaining the interior temperature. The drive system, power electronics and battery have innovative thermal management – crucial for maintaining a high operating range coupled with outstanding interior comfort.
Design and package
Audi is presenting a further variant of an electric vehicle in the form of the Detroit showcar Audi e-tron. The vehicle body has a powerful, wide and muscular stance on the road, and looks extremely compact and puristic not least thanks to the typically short sports car wheelbase of just 2.43 meters (95.67 in) – a whole 22 centimeters (8.66 in) shorter than the R8.
The sweeping line of the front end and the flat curved roof immediately identify the two-seater as an Audi. The sides reveal familiar contours: The way the dynamic line is tailored above the sill and the prominent wheel arches, as is typical for an Audi R, combine the front, side and rear into a monolithic entity and strongly emphasize the typical Audi feature of round wheel arches enclosing the large 19-inch wheels. The highly tapered front end gives the Detroit showcar Audi e-tron distinctly wedge-shaped basic proportions.
1.78 meters (70.08 in) wide, just 3.93 meters (154.72 in) long and 1.22 meters (48.03 in) tall – those are the classic proportions of a sports car. That leaves space ahead of the rear wheels for the 399 kilogram (879.64 lb) battery unit, with converter and power electronics.
The two electric motors, which have their own cooling system, are mounted on the rear axle. This special package, featuring a 40:60 weight distribution, ensures perfect balance, which contributes to the driving dynamics of the Audi e-tron.
The trapeze of the single-frame grille dominates the distinctly wedge-shaped front end and is flanked by two large air intakes. The top of the grille merges into the flat strips of the adaptive matrix beam headlight modules with their clear glass covers. All light units use ultra-efficient LED technology.
The headlights are the core of a fully automatic light assistance system that reacts flexibly to any situation. The new technology recognizes weather conditions and adapts the illumination to rain or fog. The technology at the heart of the light assistance system is a camera that works together with a fast computer to detect oncoming traffic, recognize lanes and measure visibilities, such as in the event of fog.
If there is oncoming traffic, the high beams are turned off in the corresponding section of the illumination field. The cornering light system analyzes data from the navigation system and illuminates corners before the driver steers into them. The Detroit showcar Audi e-tron does not have conventional fog lamps that consume additional power. It intelligently varies the low beams instead; in fog, for example, it produces a wider, more horizontal illumination field, thus significantly reducing the glare from the car’s own lights.
The variability of the headlights is also reflected in their design. The LED elements change appearance and thus the character of the front end of the vehicle depending on the speed driven and the ambient conditions. The innovative lighting technology now offers the Audi designers almost as much design freedom as the shape of the body does.
One design element that is specific to electric vehicles developed by Audi – such as the Audi e-tron – are the air intakes in the single-frame grille and behind the side windows on the C-post. They are closed flush under normal circumstances and opened by retracting slats when additional cooling air is required. The slats above the drive unit then also open to provide a better through-flow of air. These measures, too, maximize efficiency – the concept car is outstanding for an already low drag coefficient that is further improved when the flaps are closed.
The ASF body
Systematic lightweight construction is an even more important prerequisite for efficiency and range with electric vehicles than for conventionally powered automobiles. Lightweight construction is moreover the key to thrilling handling characteristics. Audi developers focused on a core competence of the company when creating the Detroit showcar Audi e-tron: The body structure is based on Audi Space Frame technology (ASF), with a hybrid design approach adopted. All add-on parts – doors, lids, sidewalls and roof – are made of a fiber-reinforced plastic.
The combination of aluminum and carbon fiber-reinforced composite material guarantees supreme rigidity coupled with low weight. Audi will soon use this technology in a similar form for future production vehicles. Despite the complex drive system layout with two electric motors and a high-capacity battery system, the total weight of the Audi e-tron showcar on display in Detroit is only around 1,350 kilograms (2,976.24 lb).
Interior and operating concept
Visual and functional references to the new drive concept characterize the purist interior design. They establish a connection between proven Audi genes and new formal hallmarks. Typical for the Audi design idiom is the reduction of the architecture, controls and information output to the essentials in favor of visible lightweight construction and a tidy overall impression.
The slim dash has a curve that extends laterally into the door panels. With no need to allow for a transmission, shifter and cardan tunnel, the designers took advantage of the opportunity to create a particularly slim and lightweight center tunnel and convex, arching center console. The flush gear selector, with which the driver chooses between the modes forward, reverse and neutral, emerges from the tunnel when the vehicle is started.
The Audi e-tron’s cockpit, which represents a further development in an electric vehicle, is also oriented toward the driver – a further characteristic Audi trait. Instead of the classic instrument cluster, the concept car is the first Audi to be equipped with a large built-in central display with integrated MMI functions. It is flanked by two round dials.
The MMI is controlled via a scroll pad with a touch-sensitive surface on the steering wheel (“MMI touch”) – an element inspired by modern smartphones. The steering wheel itself is clearly flattened off at both the top and bottom, in a clear reference to motor sport.
A smartphone that can be integrated into the front section of the center console interfaces between the vehicle, the driver and external information sources. The driver can use a suitably equipped conventional smartphone as a car phone, address database, navigation system and video player. At the same time they can also use it as an operating unit for many specific on-board systems in the Audi e-tron. Many phones that are suitable for these functions are already available from various manufacturers.
The driver can then enter their route plan or adjust the sound system to their individual preferences, all from the comfort of their own home, for example. The Smartphone and vehicle communicate via the mobile communications network, even over considerable distances.
The system also provides a security function for the owner; within the range of the WLAN it can constantly monitor the current status of the vehicle, for instance whether all windows and doors are closed. If the Audi e-tron showcar on display in Detroit is parked at a charging station, for example, it also sends details of the current charge status to the driver’s smartphone.
While an analog speedometer on the driver’s right provides speed information, the instrument dial on their left tells them how much power is being drawn. The central display shows the range in the status bar and presents all key information from the infotainment and navigation systems. It also provides the driver with relevant data from the vehicle’s communication with its surroundings. The instruments combine the analog and the digital worlds into a single unit.
Characteristic for the concept of the Audi e-tron – and therefore also characteristic for a further development in an electric vehicle – is the near total elimination of switches and small components such as the ignition. The climate control unit is located to the right above the steering wheel. The display provides temperature and ventilation information. Again drawing inspiration from a smartphone, the system is controlled by means of a touch-sensitive sliding control.
The equally racing-inspired lightweight bucket seats combine excellent lateral support with comfort. Two contrasting colors delineate the various zones of the interior. The colors and the high-quality materials combine elegance and sportiness.
Drive system and energy supply
Two asynchronous electric motors with a total output of 150 kilowatts (204 hp) give the Detroit showcar Audi e-tron the performance of a genuine sports car. The concept car can accelerate from 0 to 100 km/h (0 – 62.14 mph) in
5.9 seconds if necessary, and goes from 60 to 120 km/h (37.28 – 74.56 mph) in 5.1 seconds. The torque is distributed selectively to the wheels based on the driving situation and the condition of the road surface, resulting in outstanding traction and handling.
The top speed is limited to 200 km/h (124.27 mph), as the amount of energy required by the electric motors increases disproportionately to speed. The range in the NECD combined cycle is approximately 250 kilometers (155.34 miles).
The energy storage unit is charged with household current (230 volts, 16 amperes) via a cable and a plug. The socket is behind a cover at the back of the car. The charging time when the battery is empty is around 11 hours, but heavy current (400 volts, 32 amperes) cuts this to around just two hours.
The battery is charged not only when the car is stationary, but also when it is in motion. The keyword here is recuperation. This form of energy recovery and recharging of the battery is already available on many Audi production models. During braking, the alternator converts the kinetic energy into electrical energy, which it then feeds into the on-board electrical system.
The Detroit showcar Audi e-tron in its further developed version goes one decisive step further into the future; an electro-mechanical brake system means the potential of electric motors for energy recovery can now be exploited. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel, electrically actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire (“brake by wire”). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied.
By virtue of being isolated from the brake pedal, the Audi e-tron’s electric motors can convert the entire deceleration energy into electric current and recover it. The electromechanical brake system is only activated if greater deceleration is required. These control actions are unnoticeable to the driver, who feels only a predictable and constant pedal feel as with a hydraulic brake system.
An automotive first: the heat pump
The heat pump, too – which made its first appearance in an automobile on the Audi e-tron concept car shown in Frankfurt – helps to boost efficiency and range. Unlike a combustion engine, the electric drive system generally does not produce enough waste heat to effectively heat the interior. Other electric vehicles are equipped with electric supplemental heaters, which consume a relatively large amount of energy. The heat pump used by Audi – and commonly used in buildings – is a highly efficient machine that uses mechanical work to provide heat with a minimum input of energy.
A high-efficiency climate control system is used to cool the interior. It works together with the thermal management system to also control the temperature of the high-voltage battery. This is because the battery, power electronics and electric motors must be kept at their respective ideal operating temperatures to achieve optimal performance and range.
As soon as the vehicle is connected to a charging station the vehicle is preconditioned as appropriate by the thermal management and other associated systems. In cold conditions the drive system is preheated, and in hot conditions it is cooled. This preconditioning can also be extended to the interior, if necessary, so that the passengers can step into a cabin that has been heated or cooled as appropriate for their comfort.
Driving dynamics
The drive system’s power is transferred to the road by the rear wheels, reflecting the Audi e-tron’s weight distribution of 40:60.
Both the individual motors, which are installed behind the wheels close to the vehicle’s center line as wheel drives, also enable the Detroit showcar Audi e-tron's lateral dynamics to be intelligently controlled. This also boosts traction. Similar to what the sport differential does in conventional Audi vehicles, torque vectoring – the targeted acceleration of individual wheels – makes the newly developed electric drive of the Detroit showcar Audi e-tron even more dynamic while simultaneously enhancing driving safety.
Understeer and oversteer can be corrected by not only targeted activation of the brakes, but also by precise increases in power lasting just a few milliseconds. The concept car remains extremely neutral even under great lateral acceleration and hustles through corners as if on the proverbial rails.
The chassis has triangular double wishbones made of forged aluminum components at the front and rear axles – a geometry that has proven in motor sports to be the optimal prerequisite for high agility, uncompromising precision and precisely defined self-steering behavior. A taut setup was chosen for the springs and shock absorbers, but it is still very comfortable.
The direct rack-and-pinion steering gives finely differentiated feedback. Its electromechanical steering boost varies with speed, so that the Detroit showcar Audi e-tron only has to provide energy while steering, but not while driving straight ahead.
As befits its status, the Audi concept car rolls on 19-inch wheels of 35-spoke design. 235/35 tires up front and 255/35 tires at the rear provide excellent grip. Another special feature of the tires: Audi designers created the profile specifically for the Detroit showcar Audi e-tron.
