BMW surprised almost everyone when the M2 race started without S58 of the street car. It had a good reason to install the B48 instead. The smaller 2.0-liter engine causes lower running costs. The reduced drive train also lowers the weight of the car compared to the inline-Six and puts the hardware less loaded. In addition, the four-potter enables the extension machine to qualify for the racing series, which was created for cars with engines with smaller insurance.
Although two cylinders are missing, the M2 race does not lose the audible drama of its 3.0 liter counterpart. In fact, BMW’s new entry -level car was originally too loud for the Nürburgring. MS head of the engineering system told BMWblog The racing car initially did not meet the noise regulations. Here is what Dirk Hückker said:
“We had to reduce the sound for the Nürburgring a little because there are different regulations for noise, but it sounds pretty good.” He explained that additional hardware was installed in the M2 race to make them quieter. Owners can remove it for traces on which the noise regulations are not as strict as in the green.


The M2 racing uses a completely different exhaust gas system than road shipping. It is a motorsport-specific setup with a racing catalyst and an optional adjustable exhaust flap. BMW adapts the pipelines from the exhaust system of the M4 GT4 for the four -cylinder engine to ensure that the car is still roaring.
If you plan to bring your personal car into the famous German race track, you should be aware that the Nürburgring actively monitors the sound levels. In one of the safety regulations applicable to tourists, it says that “the sound performance level of 130 dB (A) must not be exceeded”.
In a related hint, said Häcker, told BMWblog The M2 race in the Nordschleife is actually faster than its six-cylinder predecessor, the M2 CS Racing (F87). At the same time, it is conveniently slower than the more expensive M4 GT4.
