Self Study Program 331 – Variable Anti-roll Bars on the Touareg

VAG SSP 331. The running gear is a key component of the entire vehicle. It transmits all the forces acting between the road surface and the body. It therefore has a direct effect on driving comfort and driving safety. The Touareg is a sporty SUV off-road but also a sporty, safe car on the road, with firm suspension, stiff dampers and rigid anti-roll bars.

The best tuning for optimum off-road mobility, however, requires soft suspension with low damping factor and less rigid anti-roll bars. To solve this conflict of requirements, ThyssenKrupp has developed a variable anti-roll bar.

It consists of split anti-roll bars which are an optimal compromise between dynamic andling characteristics, driving comfort and off-road mobility – it is a coupling that is also switchable under load.
