Having said all that. I've seen enough 335i to go limp at the first sight of being driven moderately hard by an instructor to be able to tell you that the N54 engined cars (and to that extent, N52 engined cars as well) are far more vulnerable to heat related issues on the track. Whether you believe it or not, it is up to you. Anecdotal and some empirical data suggest so.
