Rumors can finally be put to bed today, as the next-generation BMW M3 will run using a turbocharged inline six-cylinder engine.
The current M3 uses a 4.0-liter V8 that makes 414 hp, stats that will be outdone by the new engine despite having fewer cylinders. Photos of the engine have surfaced online which confirm the presence of only two turbochargers, but a third electric turbo may be hidden somewhere underneath cover. The tri-turbo setup looks to eliminate turbo lag, improve fuel efficiency and provide smooth acceleration and even power at low RPMs as well as high revs.
Displacement for the new M3 engine has been rumored at 3.3-liters, though BMW is moving towards a standardized 500cc cylinder size, which if used would put the engine displacement at 3-liters. Power figures are still a mystery, but should be close to the 450 hp mark.
Natural improvements on the next-generation M3 include lighter weight components, helping it shave a few more pounds, and a possibility of electric power steering. Transmission options should comprise of a seven-speed dual clutch transmission, while a six-speed manual might be available.
