Koenigsegg CCXR Edition

Being "green" doesn't come cheap, but for this price you can get an environment-friendly supercar, however incongruous that may seem. Manufactured by Swedish carmaker Koenigsegg, the CCXR is powered by a modified twin-supercharged V8 engine (same as its predecessor the CCX) converted to use E85 or E100 ethanol fuel as well as standard 98 octane petrol. The engine produces 1,064 bhp and the car has a theoretical top speed of 259 mph. Its chassis incorporates carbon fiber technology.
