As with the coupe and cabrio versions of the Carrera 4(S), power transmission is by all-wheel drive with a Visco multi-plate clutch, which depending on driving conditions applies between five and 40 percent of the driving power to the front axles at all times. The system thereby ensures well-balanced propulsive power in bends when driving to the limit, and improves traction even on wet or slippery road surfaces.
