The Audi e-tron S Sportback - electric torque vectoring

Source: AutoMotoTV (Glomex)

"As long as the Audi e-tron S and e-tron S Sportback are driving normally, only the rear electric motors work for reasons of efficiency. The front one is activated at lightning speed when the driver demands more power - or predictively before the traction decreases. Electric torque vectoring is added to the electric all-wheel drive: Each of the rear electric motors sends the drive torque directly to the respective wheel via an input gearbox, a mechanical differential No longer exists. The needs-based control only takes milliseconds, and it can manage very high drive torques. Especially when the driver demands the electrically powered S models on a winding route, he experiences their excellent agility and traction. Their character is more rear-oriented and still sportier than with its technical starting point, if the ESC stabilization control is on "Sport" and there s Audi drive select dynamic handling system is set to maximum performance in "dynamic" mode, the drive layout allows high lateral dynamics and, if required, controlled drifts. Near the physical limit, the relieved front wheel on the inside of the bend is slightly decelerated via the wheel brake, which prevents slippage and further refines handling. The sharp dynamics, the high precision and the uncompromising safety are based on the close networking of all control units that manage the drive and chassis systems. "
