Road Test Simulation

The Road Test Simulation Group has nine Road Simulation development cells to perform durability development for full and half vehicles.  We provide consistent, precise and quick development capability on the performance of the vehicle body, chassis and suspension structures. Vehicle noise and vibration development work is performed in the tire coupled environment test cell. It is also capable of supporting the research of the performance of components made of alternate materials under extreme environmental conditions.
