Stuttgart/Friedrichsruhe, Aug 25, 2009 - A car is a highly complex product. Before it can be launched, it has to be subjected to intensive testing. Chassis testing and tuning is a core element of much of the testing. This takes place both on company premises and on public roads. The tester’s ideal was discovered during the 1960s at the small town of Friedrichsruhe, around 30 kilometres from Heilbronn.
