The division of propulsive power between all four wheels is the basis of the excellent handling and safety of Audi models with quattro drive.
And as if that were not enough: the potential of this drive concept is optimised by a series of control systems for brake and engine management. The Anti-lock Brake System (ABS), Electronic Brake-force Distribution (EBD), Electronic Differential Lock (EDL) and traction control (Anti-Slip Regulation - ASR), for example, increase traction when accelerating or braking.
When cornering, the standard Electronic Stabilisation Program (ESP) increases directional stability by comparing target and actual physical driving forces.
