Sorry i didnt know if i should have posted this here or in the e46 thread but i was wondering, are these cars pretty much the same as the e46 models in terms of performance? is it pretty much the same car but just a new body style?

Nope, new car and new engines, practically nothing is the same.

really. hmm so what about the power on them? are they all more than the e46's? example: e46 330i has about 230 hp, what does the e9x 330i have?
