The award winning V10 engine will be replaced with a twin-turbo V8. This is going against M-sport tradition because all M’s have big engines and this will be the first to get a smaller engine size. Don’t be disappointed though look at how great the twin-turbo is in the 335i and it’s really fast and I didn’t feel any lag when I drove it. The twin-turbo V8 will be obviously amazing and won’t be loud as a V10 but still a really fast car and should output the horse power somewhere close to the 572hp found in the Audi RS6.
