My question was predicated on the difference in driving Normal vs Sport mode.
Is the normal 8 Cylinder X5 in Sport mode (I assume it has one) slower and less responsive than X5M in Normal?
The 5 Series GT that I drove for 2 days as a loaner in Sport mode was quicker and more responsive than the X5M in Normal mode.

I don't believe the non M X5s have the M driving mode, which basically just makes the accelerator more sensitive. They all have "sport" mode transmission which shifts at higher rpms but the "sport" mode in the X5M is tuned completely differently and is VERY aggressive with lightning fast shifts.
