Cornering is fun with all-wheel drive, but toss in an elevation change and the tire's contact patch to the pavement becomes very small. The 2017 R8 uses the Huracan's electronic center differential to instantly transfer power front to rear. But the first generation models used a viscous coupling similar to the Diablo VT (Viscous Traction). It relies on clutch plates suspended in thick oil that are activated when the rear tires lose traction. While it might not respond as quickly as the new model, this video is proof that all-wheel Drive can be the difference between a soiled seat and a hospital bill.
