POTENTIAL Leaked engine specs:

OK guys, I was hesitant to post this because I could not verify it myself. Seems a bit fishy. However, I have seen the same data posted here, m3post.com and elsewhere. However no sign of it at the Road and Track website. It is also hard to believe that this was pulled from an off the shelf magazine and someone does not already have it scanned and posted here. Anyway the post here claims that R&T claims the info is straight from BMW. OP makes some very nice analysis vs. RS4, 335i, E46 M3 and E60 M5 power plants as well.

420 bhp @ 8300 rpm
295 ft*lb (400 Nm) @ 3900 rpm
compression ratio: 12:1
redline: 8400 rpm
