I apologize, lacking performance is not correct. Out of the 3 X5's the diesel is the "slowest". Looks like 0-60 7.2 and 1/4 mile around 15.2 seconds.
Am I correct in thinking that the X5d does better once its moving (highway speeds) rather then off the line acceleration?
I don't plan on doing any pulling unless you consider a 5 year and newborn towing. This will be my vehicle for work/day care duty. Just need some get up and go for merging on to car pool and every once in a while pass a slow car.
