Facts from our own UCP:
Noble:
With a power to weight ratio of 400bhp per tonne, the Noble M400 is by far the most powerful car in the M12 range, hitting 60mph from standstill in 3.5 seconds and 100mph in just 8.0 seconds. At the heart of the M400 is the same twin-turbocharged 3.0-litre V6 engine found in the standard M12, but thanks to high-lift camshafts, larger turbochargers and revised fuel injection, power has been increased by 21 per cent to 425bhp, while torque is up by 11 per cent to 390lb ft.
Power to weight ratio 0.4 bhp / kg
Corvette:
The new Z06 achieves 500 horsepower in an approximately 3130-pound (1419.7 kg) package and is expected to deliver 0-60 performance of less than 4 seconds, eclipse the quarter-mile in less than 12 seconds and deliver a top speed of more than 190 mph on a race track.
(for some reason UCP don't have the exact figures and only your site says the 3.4 which was done by an independant Magazine).
Power to weight ratio 0.35 bhp / kg
And power to weight ratio shows that the Z06 would get Pwn3d on a track.
