As for the posted by the 335i, am I not correct in thinking that it has been dyno-ed at 360hp and similar ft/lbs of torque, which is a lot more than it's quoted output. I will be over the moon if my M3 can post a 4.7s 0-100km/h and doubt in my hands this will be possible.
360hp on the dyno! I've never seen or heard that before. I've seen as high as 290+, but that's it. Yes the e46 M3 has recorded 4.5 to 4.9 0-60 times.
