: Peter's video is great. I watched it several times. I noted that the tach stayed buried near the red line in what I assume was 4th for what seemed like a long time (maybe this was just the digitizing effect?). My experiences with my '99 540iA Sport would have suggested the car would have automatically upshifted (this is sometimes annoying; I think it shifts too soon). I have also not seen a definitive answer on top speed for the auto sport. In an earlier post, Lew indicated all autos were mapped to 137, but Peter's video would seem to refute this...could Euro-delivery cars be mapped differently? Also, my '97 540iA would reach about 105 in 3rd, whereas new car with lower (numerically higher) rear axle ratio seems to reach only about 92-94, so it seems 4th gear has a very wide speed band, as it appeared Peter neared 140 in 4th - just the horsepower eventually catching up to the torque??
The car stayed in 4th a little longer than usual because we were coming up a slight hill at the time. When the gas pedal is pushed all the way down, past the detent, it puts the transmission into Please-The-Driver mode-- where it accelerates as hard as it safely can. Under the circumstances, yes, it stayed in 4th gear until about 140 mph. It surprised me too.
I can't comment on previous model years, but the documentation I have, as well as my own experience, says the speed limiter on 1999 540iA Sport and 540i manual cars is set at 250 km/h (according to the German-language brochure) or 155 mph (according to the English-language brochure).
