Agreed. I find them practically interchangeable with a slight added "sharpness" in Sport. My Bimmer feels like night and day between the modes. Even Eco Pro and Comfort have a bigger difference than M-B's "Economy" and "Sport". In Sport Mode I describe my car feeling like a growling feline with its claws out and fur puffed out. The Merc's simply feel like you got 1st gear added and that's that. I won't even get into the paddles and how BMW's shifts feel almost like an instantaneous F1 shifter to me, while M-B's paddles take a day and a half to shift, and make it impossible to actually manually shift while driving without getting interrupted (BMW's will let you hit the rev limiter and sit on it if you wanted to, full control). Not to mention M-B's paddles are a cheapy feeling little plastic duo while BMW's SAT's get these high quality matte black/aluminum substantial pieces.

DavidNJ: The F10's also get steering affected when in Sport. At higher speeds around turns you'll notice a more weighted and direct steering feel.
