PVT is  a technology of distributing torque across the axles and wheels. 

Some type of electronic differential, I think. The fact that it is optional means that it is not necessary for the functioning of the AWD system but that it is an enhancement.


PVT could be a must. There are some other interesting options as well.

Regarding our discussion about 458 Italia and 997.2 Turbo PDK-here is why I think all different league-new 458 will be faster on all tracks and on the road. BUT, on the road only if 458 driver use all the revs. Why? More on August 7th...Smiley
