X5Sport, Cole, weasel, anerbe, and bgsquad I agree with all of you. It definately changes shift points and helps acceleration over regular drive as long as "kick-down" isn't depressed in either mode, which over rides it.

Mdorphin, I never said it increases power, but changing shift points can affect acceleration for sure. Like weasel said, you may be confusing it with the sport button in other BMW's.

In the X5, it does not remap the throttle pedal position sensors and no, it does not add any horsepower or increase torque. Of course it takes less pedal input to accelerate. That is because of the transmission holding the gearls longer and keeping the engine at higher RPM's. You are giving the changed pedal feel as a cause, when it is actually the affect of the transmission change. I think that is also where you are a little confused.
