Traction on a high level:
quattro drive with crown gear centre differential and torque vectoring

As with every RS model, the Audi RS 5 ’10 and the Audi RS 4 Avant ’13 employ the quattro full-time all-wheel drive to put the power from the 331 kW (450 HP) engine down onto the
road. Both models have identical drivelines. An evolutionary version of the centre differential is utilised – the so-called crown gear centre differential.

This compact and lightweight component has the ability to distribute power flow between the front and rear axles instantaneously, homogeneously and over a broad range; up to 70 percent can flow to the front axle and up to 85 percent to the rear axle.

The crown-gear limited slip differential works in conjunction with the torque vectoring system, which acts on all four wheels. If a wheel on the inside of the curve loses too much traction under dynamic driving conditions, the torque vectoring system brakes the wheel before unwanted levels of slip occur. Audi also offers the sports differential option, a mechanism that uses two overlapping ratios to actively distribute the power between the rear wheels.

Power transmission is provided by the sporty 7-speed dual clutch gearbox 0B5 S tronic. In the case of the Audi RS 5 ’10 and Audi RS 4 Avant ’13, this gearbox has special characteristics which are explained in this Self Study Programme.
