4RM Four-Wheel-Drive System

Uniquely, the FF also guarantees this exceptional performance on terrain with very low grip coefficients, thanks to Ferrari's own patented 4RM four-wheel drive system. Torque is still delivered by the rear wheels, but the PTU (Power Transfer Unit) ensures that as much as is required is also transferred to the front wheels when necessary on low grip surfaces. The FF intelligently distributes torque to each of the four wheels individually, thanks to the fact that all of the dynamic vehicle controls (E-Diff, F1-Trac and PTU) have been integrated into a single CPU.

Exceptional sporty driving is guaranteed by the FF's transaxle architecture (mid-front engine with gearbox over the rear axle) and the positioning of 53% of weight to the rear of the car. Meticulous attention has been taken in lightening the engine (new castings), bodyshell (new aluminum alloys and production processes) and a host of other components. Third generation Brembo carbon-ceramic brakes are now lighter and longer-lasting, with virtually negligible wear during normal use on the road. All of these innovations have combined to produce an absolutely exceptional weight-power ratio of 2.7 kg/hp, a new benchmark for this kind of car.
