That's the one I point out when people say that an M3 cab is a waste of money and a 335i cab would be just as fast. M3 cab kills the 335i coupe so we don't even need to look at the 335i cab numbers - no comparison really.
In fact, the M3 cab is faster than the 335i coupe by a lot more than the M3 coupe is faster than the M3 cab. In other words, if you take an E92 M3 and are wondering which will make the car slowest - chopping off the roof and adding 500 lbs, or replacing the drivetrain, suspension, brakes, etc. with 335i components, well here's your definitive answer.
I couldn't have said it better - if there was that much of a difference vs. The 335 coupe, I don't see how people can argue you're better off with the 335 'vert. I've driven loaner 335xi sedans - and there is no way that car compares to the E93 in terms of acceleration or otherwise - so the slim paper difference between their respective acceleration numbers is clearly due to BMW's overly-conservative performance numbers for its M cars... I'd be willing to bet that anyone who has driven the E93 and a non-chipped 335 would agree...
