Progressive and efficient: quattro all-wheel drive

The all-wheel-drive system quattro ultra is available as an option for many engine variants. It flexibly distributes torque to maximize efficiency while also providing all the benefits of quattro for even greater driving safety and dynamics. An electronically controlled multi-plate clutch distributes torque between the front and rear axles over a wide range, as required by the specific driving situation. For excellent fuel efficiency, the rear axle of the quattro ultra is automatically decoupled under partial load insofar as the driving situation allows. When taking corners dynamically, accelerating sharply, or when the friction coefficient of the road surface requires it, the quattro system’s electronically controlled multi-plate clutch connects the front and rear axles and distributes the tractive force flexibly to where it is needed. If you accelerate hard out of a corner, power is distributed more towards the rear. In this driving situation, the power distribution between the front and rear axles is around 30:70.

Another component of the V6 TFSI powertrain is the optional quattro sport differential on the rear axle, which actively and completely variably distributes torque between the rear wheels. Unlike a conventional limited-slip differential, the sport differential can further accelerate the outer wheel when cornering dynamically, meaning it applies more torque to that wheel. This makes the A6 Avant able to turn more precisely into the curve. The sport differential counteracts the tendency to understeer early on and ensures enhanced agility. In the dynamic Audi drive select mode, the handling is more rear-biased.
