This specs are based on insider-informations, that the M3-Testmules are also used for development of the N55 succesor - for the M Performance Automobile F3x and later the .35is. So also the "F80M3" fueled with E85 in sweden could be one of this engine-test-cars. The use of the "F80" body was logical because the N55 succesor is/was for sure one candidate for the M3/M4 engine - in its highest developed form ... but it didn´t says for 100% that this engine was also really choosen.

This let german forums speculate that there is already an chance that the new M3/M4 gets an other engine than the "here confirmed" I6 - also BMW/M-GmbH insiders considers other possible F8x engine variants ... for me this are good news.

The M3/M4-engine is already the biggest BMW secret until now ... only time will tell us the truth.

Well now Uli look back at this thread... it looks like we now know the leaked photo of the M3/M4 engine was indeed that of the next M3/M4. Twin turbo inline six producing around 420 PS and 550Nm of Tq.

We also know that the current M235i/3erGT/F3x/F2x engine produces 320 HP while the PPK versions produce 340 HP.
