Commercial audi quattro (2006)

On the permanent all-wheel drive quattro® power is distributed as needed to all four wheels. This system provides high levels of active safety, and dependable traction on virtually all surfaces as well as excellent road holding, even in cross-winds. It is superior to manual all-wheel-drive systems because of this "permanent safety advantage". The Audi RS 4 and S4 quattro® drive, with asymmetric/dynamic distribution of torque, transfers up to 100 percent of available driving torque to the front or rear axle if required.
