ive never had my x5 at wot, but i do flirt with sport mode often as it makes for a more fun drive, until you look at mpg, ive had some 9 mpg weeks in my 48i... but anyway. on my bike, which is almost always at wot lol, how hard it accelerates is dependent upon rpm, which depends on what gear you are in. so with sport mode moving the shift points back, keeping you in a lower gear a little longer, i assume you are taking off from a sweeter spot in the power band. so its kind giving you a headstart. if you werent in sport mode, the car would have to downshift 1st. in sport it just takes off since you are more in the powerband, making it feel faster.... maybe lol
