quattro?, the permanent all-wheel drive
The permanent quattro all-wheel drive gives the R8 Coupé a decisive plus in terms of stability and traction compared to its two-wheel drive competitors. On the front axle an electro-hydraulic multi-plate clutch replaces the viscous coupling unit of the predecessor model. Depending on the driving situation and the weather conditions the newly developed quattro drive allows a completely free, fully variable distribution of the drive torques between the front and rear axle. In normal operation up to 100 percent of the power output is directed to the rear wheels, if required, the clutch will redirect up to 100 percent of this power output to the front axle, increasing it in continuous increments. Thanks to the mechanical, limited-slip differential on the rear axle the driver experiences maximum traction without slippage.
