Ferrari FF's 4WD system explained [video]

Here's a video that provides more details on Ferrari's new 4RM all-wheel drive system.

The 4RM is the first ever AWD system for Ferrari which the Italian brand debuted in the Ferrari Four concept, or "FF", in Geneva last week.

The 4RM (Ruote Motrici) is 50 percent lighter than a standard all-wheel drive system. The PTU (power transfer unit) takes its torque directly from the crankshaft while two separate multi-plate clutches drive the front wheels independently.

The FF is a luxury cruiser that seats 4 and has a small trunk in the rear - which Ferrari loaded with 2 golf bags while the car wooed the crowds at the Geneva show to demonstrate its (limited) capacity.

The Ferrari Four features a mid-front mounted 6.3 liter V12 engine with an output of 660 PS (485 kW / 651 bhp) and 683 Nm (504 lb-ft) of torque coupled to a seven-speed double-clutch gearbox. 0 to 100 km/h clocks in at 3.7 seconds and top speed is 335 km/h (208 mph).
