In the Audi e-tron, the brand with the four rings introduces a new quattro generation as standard: electric all-wheel drive. It continuously and fully variably regulates the ideal distribution of drive torques between the two axles – within a fraction of a second. In most cases, the Audi e-tron mainly uses its rear electric motor in order to achieve the highest efficiency – the torque is generally distributed with a rear-axle bias. If the driver demands more power than the rear electric motor can supply, the electric all-wheel drive redistributes torque as required to the front axle. This also happens predictively even before slip occurs in icy conditions or when cornering fast, or if the car understeers or oversteers.
A key factor for the sporty character and outstanding transverse dynamics is the low and central position at which the drive components are installed. The high-voltage battery system is optimally matched to the dimensions of the Audi e-tron and is located between the axles in the form of a flat, broad block beneath the passenger compartment. That makes the Audi e-tron’s center of gravity similar to that of a sedan. Axle load distribution is perfectly balanced at almost 50:50.
The long-distance range is due primarily to the innovative recuperation system, which is responsible for up to 30 percent of the range. In well over 90 percent of the time, the electric SUV recuperates solely via the electric motors. In combination with a new electrohydraulic actuation concept, that Audi uses as the first car manufacturer worldwide in a series production vehicle with electric drive, the electric SUV systematically exploits its maximum recuperation potential.
