Self Study Program 613 – Audi R8 Power Transmission PDF free online

The Audi R8 sees Audi off ering, for the fi rst time, a high-performance sports car based on a mid-engine concept.

The engine positioning fore of the rear axle helps to ensure a balanced weight distribution and a low centre of gravity. This basic confi guration allows a high level of driving stability and good transverse acceleration.

Driving dynamics are further enhanced by the combination of a bespoke mid-engine concept and quattro all-wheel drive, with a strong emphasis being placed on sportiness and driving enjoyment.

Due to the mid-engine concept and the demands on driving dynamics, the quattro full-time all-wheel drive system in the Audi R8 has been implemented in a diff erent way to previous
Audi quattro drive systems.

In the case of the mid-engine concept with quattro all-wheel drive in the Audi R8, drive is transmitted dynamically to the front axle by means of a viscous coupling. Furthermore, a limited slip diff erential in the rear axle drive improves rear axle traction under high
transverse acceleration.

When buying the Audi R8, the customer can elect to change gear manually using the 6-speed manual gearbox with double-plate dry clutch or to drive away and change gear fully automatically using the optional R tronic gearbox.

An innovative selector mechanism allows the driver to make the choice of driving in Automatic mode or changing gears manually. In addition, the driver can select Sport mode.
