My wife has just got a Tiguan, very nice. Just wondering how the 4Motion system works, any help appreciated.+++

Its all computer controlled, the drive is sent to the wheels that need it! when you pull away the drive is split 60-40 front to rear and when you reach a certain speed it goes to 90-10 front to rear! If loss of traction is detected in 1 or 2 wheels it sends drive elsewhere!

:coffee:

Are you sure?... its 60-40 when you pull away? Most Haldex's only distribute a tiny amount to the rear unless slip is detected on the fronts like the 90-10 you mention.

edit: just found this in the VW press release...

As soon as the clutch detects slip at the front axle, more engine torque is applied to the rear axle. Normally, 90 percent of the propulsive force is to the front wheels and ten percent to the rear. In extreme cases, however, nearly 100 percent can be transferred to the rear axle.
