Ferrari FF 4RM All-Wheel Drive System Explained [Video]

Ferrari FF 4RM All-Wheel Drive System Explained [Video]

Unveiled last week at the Geneva Auto Show, Ferrari has just released a video detailing the sophisticated AWD system used in its new FF model.

The 4RM system (as it’s called) delivers RWD driving dynamics in regular conditions, only sending power to the front wheels when slip is detected. To do this, Ferrari uses a Power Transfer Unit (PTU), that delivers torque directly from the crankshaft to each of the front wheels individually. As a result, power can be distributed individually between left and right sides on both the rear and front axle for maximum grip.

Weighing 50 percent less than a conventional AWD system, it helps keep the car’s overall curb weight down, while maintaining a weight distribution of 53/47.
