An eight-speed tiptronic distributes the power of the enhanced-output V8 engine to the quattro drivetrain with a sport differential. The lower gears of the classic torque converter transmission are tightly spaced for sporty performance, while their high overall gear ratio of 7.0:1 reduces fuel consumption. All gear changes are fast and very flexible. The highly efficient oil pump and the heating of the transmission by the engine coolant during the warmup phase contribute to the high efficiency of the eight-speed tiptronic. A hydraulic accumulator enables the start-stop function.
The Dynamic Shift Program (DSP) is responsible for transmission management. It offers two automatic modes, D and S, and is linked to the route data provided by the MMI navigation plus. The driver operates the eight-speed tiptronic purely electronically, either with the standard shift paddles behind the steering wheel or via the elegant selector lever on the center tunnel console. In both cases, a brief tap initiates gear changes.
With its asymmetric and dynamic configuration, quattro permanent all-wheel drive provides for handling that is both sporty and stable. During normal driving, 60 percent of the power is sent to the rear axle and 40 percent to the front. If one axle slips, the majority of the power goes to the other axle. The standard sport differential provides for even greater dynamics. It uses two superposition gears to steplessly vary the distribution of the power between the rear wheels. In fast curves, the sport differential literally pushes the big sports sedan into the radius.
