When did work begin on the development of the BMW M5 and how many kilometres were covered during testing?
Two to three years must be allowed for testing the development of a BMW M. In some cases predecessor vehicles are used in the first phase, enabling initial engine tests to be carried out, for example. However, this is just a short phase. The fine tuning then involves the latest models. The development departments for engine, electronics, chassis, etc. each have their own test vehicles to enable them to put the latest technology to the test. Approximately 2 million kilometres were covered throughout the world by the new BMW M5 in this way.
