Video: Ferrari describes FF’s 4RM four-wheel-drive system
Ferrari has unveiled a video detailing its new 4RM four-wheel-drive system found in the new Ferrari FF. The advanced system delivers torque to the rear wheels – however, 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. During that process, the FF distributes torque to each of the four wheels individually.

The engine is mated to Ferrari’s patented 4RM four-wheel-drive system and a 7-speed transaxle dual-clutch F1 gearbox, allowing the Ferrari FF to go from 0 to 62 mph in 3.7 seconds with a top speed of 208 mph. Fuel-economy wise, the Ferrari FF manages a combined 15 mpg.
