Haldex
Interactive, drive dynamic regulation from MTM.
Designed for vehicles from the VW Group with Haldex Controlled all-wheel-drive systems; the MTM developed system enables a permanent all-wheel-drive by allocating a 50/50 front/rear power distribution. This development is particularly beneficial to the sporty driver on snow, ice, crushed stone and wet roadways. 

The  advantage of the MTM control system

With the drive dynamic regulation from MTM the vehicle tends more to over steer than to under steer, and consequently handles better in curves or driving on snow or loose underground. Secondly it improves the vehicles track constancy with load-cycle changes.
