DEVELOPMENT CHASSIS

Predictive Chassis Concept

for Passenger Cars

© ZF

The chassis has consistently played a key role in the future of the
automobile. End customers want a dynamic driving experience without
forgoing dependability. However, at the same time, automated functions
increase demand for comfort, which car manufacturers and suppliers
must in turn satisfy. Individual components can no longer satisfy these
varied tasks alone. ZF therefore relies on the optimized combination of
chassis systems.
