I posted this on the other thread but: That would be AWESOME! I'd love a 360-400bhp I4.
Here's the issue. The m235i is already confirmed to have an N55 engine. Would they dare to put a smaller engine in the M over a regular production car? Why introduce a M235i at all? Is it going to be a "1 year only" deal like the 1M was?
That's quite confusing.
A high output I4 is definitely possible because MB just made one and BMW did buy off some MB heads, right?
