The Ferrari FF has attracted a lot of attention at this year’s Geneva Motor Show, mostly for its shooting-brake shape and top-of-the-range status. But for tech lovers, what really stands out about this car is the four-wheel-drive system under its skin, a first for a series production Ferrari model. Understanding how the system works beats everything else for engineering geeks, so Ferrari has offered us a detailed video on the 4WD system. As the company previously stated, the 4RM configuration weighs 50 percent less than conventional four-wheel-drive systems and doesn’t affect the ideal weight distribution (53/47 rear/front). When grip is high, torque is sent to the rear wheels only, as with any other Ferrari.
