The folks at BMW’s M division must be wringing their hands with glee at the furore surrounding the choice of engine for its next M3 and M4 coupé spin-off. Speculation ranging from potential V6 set-ups to tri-turbo technology have been flying across the ‘web for a number of months, but it now seems that some of the hearsay can be put to rest thanks to BMW of North America president Ludwig Willisch’s latest statement.
Willisch was quoted on BMW enthusiasts website Bimmerpost.com as saying that despite being considered early in the M3’s development phase, the V6 (as well as a six-cylinder unit based on the current M3’s V8, minus two cylinders) has been ruled out. Beyond this nugget of information, Willisch has not confirmed anything further about the next engine.
Many reports suggest an in-line six engine displacing 3,0-litres and could potentially utilise either a twin-turbo or tri-turbo induction system to produce around 331 kW.
Much like the speculation surrounding the engine, the M3’s official unveiling is also subject to debate, but the general consensus is that it will emerge towards the beginning of 2013.
