Autocar, text says 360bhp, 5sec 0-60 and 175mph top speed, info box says 305bhp, 6.6sec 0-60 and top speed165mph!
Judging by the text, the 55bhp extra horses to 360bhp and lift to 368lb torque makes this a possible M3 beater on the motorway. Sounds a very sorted and potent car over the already very impressive 335i and at £50k loaded up with extras in the Cabrio version Alpina have a very good alternative/addition to the BMW ranges line-up.
