When i test drove the 535xi, it felt quicker than when i test drove the regular 535i. Because, to be honest with you, thats the only reason why i would pick the "xi".

I'm not sure -- my "butt dynamometer" isn't that accurate. Besides, for me, the lack of a clutch pedal makes the xi a non-starter. I drove one (550i, non-sport) when i was considering the car, but not since then.
