M3 Concept: Engine

Under the engine hood, the 8-cylinder power pack is the high-speed S65B40.

With individual throttle butterflies, a generous intake air and exhaust manifold, and many more refined M-specific features such as the MSS60 engine control, the S65B40 is once again an outstanding highlight of the M series.
