Maybe the question needs to be changed a bit.

Of late, Lamborghini and Ferrari have essentially said enough is enough...i.e., the HP wars (maybe not said in exactly this way, but idea is there). Suspect that primarily due to increasing demands for increased corporate MPG ratings, they have concluded that the topic is perhaps best resolved via weight reduction (those familiar with Colin Chapman's philosophy @ Lotus can perhaps smile at this). Of course, downside of approach is that HP is relatively cheap to produce as compared to real weight reduction via use of carbon fiber and other exotic, albeit incredibly expensive, material.
