Ford GT90

Leaving aside that dated background, it's hard to tell the space-age Ford GT90 was first revealed to the world more than 17 years ago. Pumping out 720bhp from a quad-turbocharged V12, it could accelerate to 60mph in 3.1 seconds and up to 100mph in 6.2 seconds, before going onto a lightning top speed of 235mph. We're talking Bugatti Veyron performance, but way before it even existed.
Because of the heat spewed out from the V12, the spiritual successor to the GT40 was said to use Space Shuttle ceramic tiles to keep the exhaust from melting body panels.
