It ‘s been rumored before but now it would appear Auto Express has come close to actually confirming it. The tri-trubo is rumored to be a 3.3L engine that produces around 450 hp and over 400 ft lbs of torque. Obviously quite a bit different in characteristic than the current M3 ‘s naturally aspirated V8. Now let ‘s take a look at what three turbos actually means.
According to Auto Express (who spoke with BMW’s M Division head, Dr Friedrich Nitschke) two turbos will be powered by exhaust gasses while the third will be powered via electricity. Along with a mix of light weight components this next generation M3 will be dramatically more efficiency than the current car or even it ‘s E46 predecessor.
