BMW UK hosted yesterday an M gathering at their headquarters in London. Among many exciting M models, two of them stood out in particular – the new BMW M2 and M4 GTS.

The guests not only had the chance to inspect from upclose the two track monsters but also to listen to the engine sound of the two.

The M4 GTS features a titanium muffler on the exhaust system helps with weight savings while delivering an impressive growl.


BMW seem to have learned something from the M235i and the new M2’s exhaust comes with special flap system. The traditional twin dual tailpipes are still present – a clear sign this is an M car – with electrically controlled flap delivering the distinctive BMW M engine soundtrack across the entire rev range without pushing volume levels to their stipulated limits.


In addition, drivers can use the Driving Experience Control switch to select a driving mode and a preconfigured sound to go with it.

But which one sounds better? Click below to find out.
