New pictures of the Ferrari Cars
So what about the four-wheel drive, then? Uniquely, power is also taken off the front of the engine, which is behind the front wheel centres. It's fed to a compact lightweight unit containing a set of clutches that can progressively feed in torque to a tiny integrated gearbox and front diff. It has only two gears, roughly the equivalent of third and seventh in the main box. How can this be? Because the clutches are always slipping under electronic control, and the front tyres would never be able to make use of all the V12's torque in first or second.
What this means is the car's electronics can smoothly dial up a portion of drive to the fronts if they predict a loss of traction at the back. Yes, they're predictive as well as reactive. And they only do this in the road and slippery-road settings of the steering-wheel manettino. In the more hardcore modes, you can still run it as pretty well entirely rear-drive.
