i believe this video, and thats what i would expect from the 335.
i think BMW underrated the 335 because there has to be a gap between the top level 3er, and the M3. otherwise, whats the point of the M3?
lets look at the numbers, just stock numbers too. the N54 makes 300hp near the top of the tach, but it makes 300 lb/ft of torque steadily from below 2k all the way past 5k. the S54 (and believe me, i love this engine) makes 333hp. its only slightly better, but it makes less torque and its a peaky curve. 262 lb/ft with a peak, vs steady 300 lb/ft torque?
completely believable. in fact, i bet a tastefully done 335i will give the E92 M3 a run for its money. . .
