The BMW M GmbH is currently preparing the generation change for the iconic sports cars. With driving dynamics tests performed under racetrack conditions, the series development process for the new BMW M3 Sedan and new BMW M4 Coupé (fuel consumption combined: 10.9 – 10.5 l/100 km [25.9 – 26.9 mpg imp]; CO2 emissions combined: 249 – 239 g/km, preliminary data) is entering its crucial phase. With a significant increase in performance vs. the predecessor models and an M-specific suspension setup, newly developed straight six-cylinder engines once again set benchmarks in the segment of high-performance sedans and coupés of the premium midrange class. Comprehensive innovations in the areas of drive, wheel suspension, springs, dampers and braking technology require thorough testing on public roads at the BMW Group testing centres in Miramas, Southern France, in the Swedish town of Arjeplog as well as on a number of different racetracks.
