The same logic goes with the 335i that has been recorded to post 0-60 times of 4.9 and 5.1. so the e92 M3 should be able to do much better and it has at 4.4 secs.
Extra power does not always equal huge improvements, especially when you are only driving the rear wheels, traction is the problem, getting the power down is usually harder with more power.
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.
