Konigsegg CCXR


CCXR - THE FIRST GREEN SUPERCAR
The CCXR will take you to an entirely new level of performance. It is a derivative of the CCX, with a highly modified engine that can run on E85 and E100 Biofuel as well as normal 98 octane petrol (Europe). When run on regular petrol, the 4.7 litre twin-supercharged Koenigsegg engine delivers 806 Bhp, but this figure rises to an astonishing 1018 Bhp when the car is run on E85 Biofuel. The CCXR is the first green supercar in the world and thereby sets a great example for others to follow. Since the ethanol in E85 fuel has a much higher octane rating and internal cooling capacity, the engine can run with higher compression, boost pressure and more spark advance compared to the normal petrol-fuelled CCX, whilst still maintaining the same exhaust temperature.
