Ferrari FF, how the four-wheel drive

Piero Ferrari said that the new Ferrari FF his father would have liked. It is certainly a model that creates a groove with the past and that the Maranello, the 599 Hybrid with a year ago, draw a line on the state of the art achieved by the technology. Ferrari has changed the interpretation of the theme that concerns sports coaches.

The FF (Four-Four-wheel drive and four-seater) is released from the deep past being able to combine extreme performance with good usability and design with highly innovative and personal. The 4WD system (4WD) has been patented directly by Ferrari. The couple is always supplied to the rear wheels and, thanks to PTU (Power Transfer Unit), part of it is transferred to front axle in the amount and limited to the time needed to address low-grip surfaces.

This transfer is done through a special torque clutches included in the PTU. This is connected to the crankshaft through a system of sprockets and his sudden activation is ensured by a hydraulic control device. The FF manages the torque moment by moment and as a percentage variable to each wheel by integrating into a single unit of all vehicle dynamics controls installed: E-Diff electronic differential, traction control and precisely the F1-Trac PTU.

The sporty dynamics is ensured by the architecture with a transaxle (front mid-engine, gearbox and rear by the axis) and the weight distribution with 53% of the weight on the rear. Among other technical innovations, please note the new V12 with direct fuel injection mated to the F1 double-clutch gearbox with seven gears.

Maximum output of 660 hp at 8000 rpm with maximum torque of 683 Nm at 6000 rpm, of which 500 Nm at 1000 rpm available. Acceleration 0-100 km / h is 3.7 seconds and a top speed of 335 km / h. Consumption amounted to 15.4 liters per 100 km and CO2 emissions to 360 g / km, 25% less than the previous V12 also thanks to the Hele (High-Low Emissions emotions) which also includes the Stop & Start .

Thanks to the painstaking weight reduction, the FF has a power to weight ratio of 2.7 kg / hp.
