Hi, I am just curious if anybody with the 730/735/740s would like to do a little test for me. I am wondering at what RPM does your great BMWs work at the following speeds (IŽd guess all would be in 4th gear or O.D. if auto, and 5th if manual? But you can specify) 50mph (80km/h) = ? RPM 60mph (100km/h) = ? RPM 75mph (120km/h) = ? RPM 100mph (160km/h) = ? RPM Ok, not all of you want to break the speedlimits so I am not encouraging to speeding here ;) Just want to compare the V12s to the other ones, wondering if they work at the same low RPMs.
