It is the same physical engine, the only difference is in the ECU.

P.S. on our 335is the letters are in lower case.
agree I should have said 335is. I think what you mentioned in regards to performance makes it different than the 335i doesn't it? The new 335i does not have the N54 engine, it has N55 which is different. Also on the exterior is different, like the exhaust system, mirrors, front grill. All of these makes it different, at least to me
