Quad tail pipes have been a signature element of BMW M cars which was found missing in the spy pictures of the M2 prototypes. But, not anymore, a BMW M2 test mule was spotted with quad tail pipes, indicating at development moving to the next phase.
According to the source it looks identical to the prototypes spotted earlier except this change. There were rumours about BMW working on a four-cylinder engine, for its M range of vehicles. With the availability of the M235i, it is unlikely that the M2 will get a four-cylinder mill. Instead it will get the turbocharged 3.0-litre, straight-six engine used in the now extinct M3 and the M4 tuned to produce 374bhp.
If BMW gets this car right, it can be the spiritual successor to the now defunct M3. The 2 Series has many won many accolades for its handling already and who knows this might turn out to be the best variant in the range.
