I read a recent mag article on the Saleen S7R (twin turbo 750HP). They specifically stated that Saleen was gunning for the Veyron in regards to top speed. 750HP may not be much, compared to 900+, but the Saleen weighs well under 3000lb. It's power-to-weight ratio is MUCH better, giving it huge potential to dethrone the top speed king. This is speculation on the mag's part, as they haven't had the chance to run the Saleen through their normal testing rigors.
