Più due estratti interessanti, anche se un pelo discordanti, sul cambio anteriore:

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.

Ah, you’re thinking, how can a two-speed gearbox in the front work with a seven-speed gearbox in the rear? Well, front first is geared six percent longer than rear second, and front second is geared six percent longer than rear fourth (reverse is geared the same). Got that? So the front transmission’s first gear covers the rear’s first and second, and its second gear covers the rear’s third and fourth.
