As standard, the 4.0 TFSI is coupled to an eight-speed tiptronic with optimized switching times and launch control function. When coasting and rolling out, a clutch in the central transmission opens and interrupts the drive shaft. With its electric oil pump, the tiptronic can nevertheless engage the gear required for restarting while coasting with the engine switched off. Special ventilation allows off-road use.
The V8 power of the 4.0 TFSI goes beyond the permanent all-wheel drive quattro, onto the road. Constructed as a planetary gear, the purely mechanical center differential normally distributes the drive forces to the front axle and rear axle at a ratio of 40:60. In the event of slip, more drive torque automatically goes to the axle with the better traction. Up to 70 percent can be directed to the front wheels or up to 85 percent to the rear wheels.
The wheel-selective torque control perfects the safe and agile handling of the new RS Q8**. During dynamic cornering, the optional quattro sport differential distributes drive torques between the rear wheels as required. This active torque vectoring improves traction, stability and dynamics.
