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.
