Personal preferences can account for much of that. So many people diefy the Veyron and gush about how it is the all time king of super cars. I have trouble liking any sports car that weighs more than an F-150, regardless of what else it an do.
I for one was expecting much more from a RWD version in the stats department and it leaves me wondering what it would be like to drive with a little less enthusiasm than I had previously felt for the concept. Did they decide not to increase the power because they were worried about percieved 'safety'? If so, that would kind of be a downer. When it comes down to it loving a car is about passion and passion is highly subjective and can be influenced by little details like that.
