340 kW of power, from 0 to 100 km/h (62.1 mph) in 3.9 seconds and a driving range of up to 450 km (279.6 mi) – Audi has further developed the R8 e-tron thoroughly. The high-performance sports car combines an all-electric high-powered drive system with radical solutions in lightweight design.

Visually, the 4.40 meter (14.4 ft) long Audi R8 e-tron is recognizable by its unique lighting solutions on the air inlets, front apron and sideblades. Its exterior skin, painted in Magnetic Blue, combines body parts made of aluminum and carbon fiber reinforced polymer (CFRP), such as the front and rear lids. Thanks to aerodynamic modifications to its cooling air inlet, rear spoiler, diffuser, underbody and sideblades, the drag coefficient (Cd) of the R8 e-tron is just 0.28. Its Audi Space Frame (ASF) is based on the multimaterial design of the V10 version, which is extended by a rear body module made of CFRP. Despite its low weight, the corrugated bulkheads that conceal the luggage compartment can absorb a lot of energy in a rear-end collision.

The T-shaped battery is structurally integrated in the middle tunnel and is mounted behind the occupant cell – this location offers a low center of gravity and an axle load distribution of 40:60 (front/rear). The high-voltage battery is based on lithium-ion technology. The liquid-cooled lithium-ion battery consists of 52 modules. Compared to the first e-tron technology platform, the energy capacity of the new 595 kg (1311.8 lb) battery system was boosted from around 48.6 kWh to 90.3 kWh without requiring any package modifications.

Thanks to the high energy density, which was increased from 84 to 152 Wh/kg, the R8 e-tron can be driven up to 450 km (279.6 mi) on just one battery charge – previously it was 215 km (133.6 mi). In the Combined Charging System (CCS) for charging with DC or AC electricity, the battery can be fully charged in well under two hours. The driver can control this process remotely by smartphone, if the user has installed the relevant Audi connect app.

Immense tractive power: 920 Nm (678.6 lb-ft) of torque
The two electric motors on the rear axle each output 170 kW and 460 Nm (339.3 lb-ft) of torque. The R8 e-tron, which weighs just 1,841 kg (4058.7 lb) empty (without driver), sprints from 0 to 100 km/h (62.1 mph) in 3.9 seconds and can accelerate to an electronically governed top speed of 250 km/h (155.3 mph) while developing its unique e-sound. Targeted Torque Vectoring – a need-based distribution of drive power between the rear wheels – gives the car maximum stability and dynamism.

Intelligent energy management and an electromechanical brake system at the rear axle ensure high rates of energy recuperation. The suspension springs consist of glass fiber reinforced polymer (GFRP), and the anti-roll bar is made
of CFRP.

The R8 e-tron rides on aerodynamically optimized, high-gloss 19-inch aero wheels that were specially developed for this car. At the front axle, size 225/40R19 tires enable precise steering response. Size 275/40R19 tires transfer the torque of the electric motors to the road. The tires were specially developed for the requirements of an electric supercar, and they combine sporty driving properties with efficient rolling resistance values. Extremely sporty 20-inch wheels of the production R8 are available via the Audi Genuine Accessories program.

In the finely crafted interior, the R8 e-tron offers illuminated door sill trims, folding bucket seats and a specially configured Audi virtual cockpit. A heat pump removes waste heat from electrical components for thermal management and for interior climate control – an important efficiency module of the overall concept.

Audi also uses the latest development stage of the R8 e-tron as a high-tech laboratory – it also continues to play an important role in developing electric mobility of the future. The R8 e-tron will be produced in the small-scale production facility of quattro GmbH at the Audi Neckarsulm site in the Böllinger Höfe.
