434 kilowatts (590 metric horsepower)
434 kilowatts (590 metric horsepower) of system power – that is an impressive figure for the potential of the all-electric drive. Separate electric motors are fitted to the front and rear axles. In both cases these are permanently excited synchronous motors. They put down the torque onto the road via all four driven wheels – naturally the new Audi e-tron GT concept is also a genuine quattro. An electric quattro to be precise, since there is no mechanical link between the front and rear axle. The electronic control system coordinates the drive between the axles as well as between left and right wheels. That means optimum traction and just the desired amount of slip.
In the future, the vehicle should accelerate from 0 to 100 km/h in around 3.5 seconds before going on to 200 km/h in just over 12 seconds. The top speed is regulated at 240 km/h to maximize the range.
The range of the concept car will be over 400 kilometers, determined according to the new WLTP standard. The required drive energy comes from a lithium-ion battery with an energy content of more than 90 kWh, which takes up the entire underfloor area between the front and rear axle with its flat design. The decisive advantage of this design is the car’s extremely low center of gravity – comparable with that of the Audi R8 – which in turn decisively benefits dynamic handling. All-wheel steering translates this into a perfect synthesis of sports car-like agility and precision, augmented by superb directional stability.
The recuperation system increases the range by up to 30 percent on Audi electric vehicles – this is essential even with such a sporty car as the Audi e-tron GT concept. The recuperation involves both the two electric motors and the electrohydraulically integrated brake control system. Different recuperation modes are combined: manual coasting recuperation using the shift paddles, automatic coasting recuperation via the predictive efficiency assist, and brake recuperation with smooth transition between electric and hydraulic deceleration. Up to 0.3 g, the Audi e-tron GT concept recuperates energy solely via the electric motors, without using the conventional brake – that covers over 90% of all decelerations.
