As a true supercar the R8 not only offers blistering speed but awe-inspiring handling. Featuring the legendary quattro all-wheel drive system, the R8 inspires driver confidence, giving you traction when you need it, where you need it, regardless of road conditions. To accommodate the extreme performance of the R8, quattro utilizes a continuously variable torque distribution, dynamically adjusting power to the wheels with the best traction.

With a significant 85% rear torque bias and up to 30% available for the front wheels as needed, this highly specialized quattro system provides the R8 with a balanced driving experience unlike any car on the road.
