Drivetrain

The transmission is a major factor in the efficiency of the new A6. They stand out due to their low internal friction and high efficiency; with their wide gear-ratio spread, they are high geared for high speeds. The automatic transmissions have access to predictive route data from the navigation systems and are integrated into the engine's thermal management system.  When a vehicle turns a corner, the inside wheels cover a shorter distance than those on the outside. Differential is in front of the clutch and immediately behind the engine. Accordingly, the front axle on the A6 is positioned farther forward, making for a long wheelbase and a harmonious axle load distribution.

The new A6 implements the latest development stage of the permanent all-wheel drive with the crown-gear center differential.  To compensate for the different wheel velocities between the front and rear suspensions, quattro® permanent all-wheel drive has an additional center differential between the front and rear suspensions.  Audi's quattro® permanent all-wheel drive, has had over 25-year-long tradition.quattro® permanent all-wheel drive has an additional center differential between the front and rear suspensions.  This system distributes power in an especially flexible, dynamic manner, while also featuring a compact, lightweight construction. The basic ratio of power distribution between the front and rear axle is 40:60 a sporty, rear-biased characteristic.
