Self Study Program 414 – 4MOTION with Four-wheel Drive Coupling Generation IV
VAG SSP 414. Volkswagen has been using Haldex couplings for its 4MOTION four-wheel drive system since 1998. The new generation of four-wheel drive coupling is being used for the first time in the Tiguan.
The new four-wheel drive coupling exclusively uses electronic control so that any amount of torque can be built up at any time regardless of slip. The distribution of the drive power to the axles is variable and depends on the driving situation. The new four-wheel coupling in the 4MOTION system can thus react ideally and extremely fast to all driving situations.
You will find information on the previous generations of the Haldex couplings in self-study programmes:
- SSP206 – Four-Wheel Drive with Haldex Coupling
- SSP333 – 4MOTION with Haldex Coupling, year of models 2004
