The R8 has Haldex, but it's reversed for a primarily rear-drive car. The previous generation had a basic viscous coupling system.

On the front axle, an electrohydraulic multi-plate clutch replaces the Visco clutch of the predecessor model. The newly developed quattro drive system enables completely unrestricted and fully variable distribution of the drive torque to the front and rear axles depending on the driving situation and weather. In normal operation, up to 100 percent is transmitted to the rear wheels and, if required, the clutch continuously diverts up to 100 percent of this torque to the front wheels. Thanks to the mechanical differential lock on the rear axle, the driver experiences maximum traction without any slip.

Its electro-hydraulically controlled multi-plate clutch is mounted on the rear axle. The special pump design reduces weight by around 1.5 kg (3.31 lb) compared with the previous model. The distribution of drive torque between the axles is controlled electronically within fractions of a second.
The intelligence of quattro drive - in other words, the software that determines precisely the possible torque distribution between the front and rear axles - is a completely new development especially for the TT. The innovative control philosophy continuously senses the ambient conditions, driving status and the driver's wishes. This means that the ideal distribution of torque is calculated and the TT's dynamic drive characteristics enhanced in every situation.
