The Touareg 2011
Chassis and Four-wheel Drive Concept
Design and Function
The Touareg 2011 is a completely new development. It combines the sporty performance of a car with improved
off-road capabilities. This makes it a luxury-class off-road vehicle that unites the requirements of on-road and
off-road driving even more perfectly.
The chassis has been optimised not just to improve the performance, but also to reduce the weight of components.
The chassis, which is up to 47kg lighter compared with the previous model, makes a substantial contribution to
reducing fuel consumption and carbon dioxide emissions.
