Drivers can create their own personal driving experience using the standard dynamic handling system. Audi drive select influences the characteristics of both the engine and the steering. What’s more, the system also adapts the characteristic curve for shifting, as well as the exhaust flaps and further optional modules to suit the four modes: auto, comfort, dynamic and individual.
In the induction tract, the intake valves close well before the piston reaches bottom dead center. This very short opening time keeps the fresh gas flow comparatively small. When the piston moves back up again after reaching bottom dead center, the compression phase starts later than usual. This allows a high geometric compression ratio of 10.0:1 - the combustion then takes place in a relatively small volume. In comparison to the short compression phase, the expansion phase is extended, which results in a high level of efficiency.
The bi-turbo‘s power flows through a sportily-tuned, eight-speed tiptronic transmission with optimized shift times and on to the quattro permanent all-wheel drive which features a self-locking central differential. The drive forces are asymmetrically distributed between the axles in the ratio of 40:60. Dynamic handling with optimum traction and the best-possible levels of safety are thus guaranteed. Audi Sport also offers an optional rear sport differential.
