I knew it would eventually found it way here, first the bimmerforums, then bimmerfest.
The author has made quite a few mistakes in that article due to limited research and knowledge. "540i is a step above its M counterpart" ??? LOL
LOL, yeah, it's not even close. In fact, it's about the perfect equal of the E90 330i 6MT in terms of acceleration. I bought a 540i/6MT new, took PC delivery, etc, then two years later bought the M5...had them both for a few months. The 540i/6MT is a great car (at least new) but nothing like the M5. Many, many board members back in the old days were 540i/6MT owners; at one time it seemed like a board requirement to have owned one.I still would not believe that the 540i would really come that close to the M5 in a straight line.
