The new 2025 BMW M2 Racing is positioned as the grassroots factory race car. And the B48 was the perfect engine choice for that application. The new BMW M2 Racing is affordable and offers race teams and drivers uncompromising performance, durability, and driving pleasure.

At BMW M Motorsport, supporting customer racing with race cars that are maintenance-friendly, cost-efficient, and exciting to drive is of high importance. The four-cylinder in the M2 Racing is derived from BMW's B48 engine family, basically the turbocharged four-cylinders used throughout the brand's lineup. BMW has revealed the M2 Racing, a new race car based on the street legal M2 coupe.

Unlike that car, it uses a turbocharged inline four. The M2 Racing uses a tuned version of BMW's familiar B48 engine, borrowed from the 230i but massaged to make 308 horsepower and 310 lb. Why would BMW, known for its legendary straight-six engines, decide to drop a 2.0-liter B48 four-cylinder engine into a purpose-built race car? What happened to the beloved S58 inline-six found in the road-going M2 and M4?

The main reason is running costs, with the B48 easier and simpler to replace and repair parts compared to the S58. In addition, BMW stands by the fact that the M2 Racing "combines easy operability with low operating costs," and much of that is due to the use of the B48, which is lighter than the S58, a key feature of any true race car. Unknown with races, but newly familiar with the M2 race that has just been published? You are probably wondering why BMW packed the B48-Inline Four with the racing car in contrast to 3.0-liter six from the street M cars.

After all, M stands for motorsport, isn't it? The B48 four. The BMW B48 is a turbocharged inline. Instead, the peeps at BMW M Motorsport decided on the regular production B48 inline.
