Four titles in three years. The vehicle designation BMW M4 DTM stands for big success. In keeping with this, BMW Motorsport has a lot planned for the new season of the DTM, which starts on May 5, 2017. This year marks the dawn of a new era. A change in regulations led to an overhaul and significant new developments for the successful model BMW M4 DTM. Distinctly modified aerodynamics and an enhanced performance of over 500 hp provides for even more excitement and attraction at the race.
50 times 15: that’s the formula which the BMW Motorsport aerodynamics engineers were working with when they developed the new BMW M4 DTM before the 2017 season. 50 days in the wind tunnel were allowed, at a maximum of 15 hours per day. Not a minute more. The parameters were set by the German Motorsport Association for all manufacturers. Every minute counted. This made preparations all the more important. Before it went into the BMW Aero Lab, the aerodynamics experts ran through the effects of changes on the individual components – even before a component was built. The Computational Fluid Dynamics (CFD) already used up to 600 high-performance computers in almost a full day.
