in my 135is which 'only' has 320hp I get about 12-15mpg through Brooklyn and Manhattan city driving. On the freeway (most of my commute in and out of NYC every day, if I am VERY relaxed I get 30 mpg. In my normal driving state I get 25mpg on the freeway which also includes some level of stop and go freeway traffic.
I can't imagine the M3 doing better than that.....maybe if they really worked hard they can equal it.
