Ready for the new season.

The new BMW M4 DTM.Ready for the new season.

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.

Wind tunnel testing.

If the part proved itself during the simulation, variations of it were tested further on the 60-percent model in the wind tunnel.
Of particular focus was the structure of the car model used in the wind tunnel. In comparison to the development of the 2014 BMW M4 DTM, it was constructed modularly in order to permit faster changes to individual aspects of the aerodynamics. For example, the engine bonnet consisted of eight components during the tests, each of which could be swapped out independently.

Even more innovative power.

The DTM regulations for the 2017 season provide for a larger diameter for the air flow limiter, through which the BMW V8 racing engine draws its combustion air. The power pack consists of almost 4,000 individual parts, weighs only 148 kg and now has over 500 hp. For its construction, BMW Motorsport uses resources from BMW AG. The high-tech foundry connected to the BMW factory in Landshut, for example, contributed to the large castings like the cylinder head and crankcase. Even small parts come from innovative manufacturing processes: a water pump wheel made of aluminium alloy comes from a 3D printer and has proven itself to be superior in the world of racing sports since 2015.

The excitement grows day to day.
