Well I think mclaren made the decision to make this a close fight and maybe too close.. All they needed to do is add 20-30hp and torque (zero cost for this engine), make steering and engine response a bit faster (again zero cost), and put an lsd (heavier but with sports seats u can negate most of it) and it would have blown the 458 out of the sky. But they needed to leave space for upcoming s models.
I guess it is how you dial in the comfort vs sportiness compromise. I think with the active suspension perhaps it would have been possible to sacrifice 10% of "everydayness and accessibilty to everyones driving skill" to get 30% more in perceived "driver involvement". But strictly speaking the car would have been more fun but not better really (only faster)..
The journalists have a point. They do blow it out of proportion of course to sell more magazines.
Maybe the AMS test with a NBR faster time of 20+ seconds will set things right.
