What is faster ? An AC Cobra replica or a Jaguar XKR-S convertible ?

The XCS Fusion Cobra replica has been design by the team behind the Dax Rush, and features the patented anti-roll system from the aforementioned Caterham Seven clone. It also happens to feature a tubular spaceframe chassis and switchable electrically assisted steering. Oh, and a Chevrolet LS3 V8, which with the aid of a supercharger, develops up to 639bhp. And the car weighs 1080kg, resulting in a Bugatti Veyron-beating 590bhp per tonne. It's quick, certainly, but can it beat the Jaguar XKR-S in a drag race?
