Electronic safety systems

The onboard technologies on Audi vehicles make them some of the safest in the world - especially when road conditions are less than perfect.

ABS

The Anti-lock braking system works by momentarily releasing and then applying the brakes when it detects a skid resulting in reduced stopping distances and the ability to turn under emergency braking.

ASR

Anti-slip regulation - or traction control - reduces power to any wheel that is in danger of spinning. Full power is returned when traction is re-established.

EBD

Electronic brake-force distribution works in conjunction with ABS to ensure an even maximum braking force between the front and rear wheels.

EDL

The electronic differential lock allows a smooth getaway on surfaces with mixed levels of grip.

ESP

Audi’s electronic stability programme uses the four technologies above. It identifies the intended direction and applies braking to individual wheels to help keep the car stable.
