3.3 liter triple turbo inline 6 cylinder confirmed for next generation F30 M3 - Motor to possibly power X3 M as well
Looks like those triple turbo rumors
6 cylinder rumors for the X3 M were true. Auto Express
reports they confirmed the triple turbo 3.3 liter with head of M Dr. Nitschke. 450 horsepower is the expected output with 2 turbos fed by gasoline and 1 that is electric. How would this work? We aren't entirely sure how BMW plans to arrange them but the attached diagram may help resolve how the turbos could be positioned with an inline 6 with the electric turbo in the middle working as a sort of quasi-compound turbo setup.
