VW and Audi also uses a similar electronic system ( Haldex ) in many cars but this acts as an FWD when grip is good. I think the T-egg and Q's uses the same type of Torsen system as the the base diesel. All has dumped the low range transfer case. The diesels manual lock is for the center diff, something that as i understand it the gassers system handles automatically.
Does the Porsche uses electronic locking differential like BMW X5 or does it uses a mechanical system like the X6 for side to side?
