March 2nd, 2007 - When thinking about supercars, one of the last things that spring to mind are their environmental friendliness.

Even though the very low and exclusive production volume of Koenigsegg can hardly be considered to have a measurable impact on the Co2 problem that global society is facing, it is an impressive statement that even a small and extreme company like Koenigsegg can afford to develop environmentally focussed solutions.

By following conscientious and forward thinking strategies, Koenigsegg has managed to create the Bio Fuel Powered CCXR - environmentally friendly 1200 with even more spectacular performance than the standard CCX.

These two almost confl icting results are made possible due to the simple fact that the ethanol in biofuel has the positive side effect of cooling the combustion chambers, as well as a higher octane value, well over 100 RON, which gives the high power. Due to the fact that the biofuel has higher octane and cooling characteristics, the power has gone up to 1018 hp at 7200 rpm and the torque to 1060 nm at 6100 rpm.

It is natural to expect a substantial gain in power when optimizing the engine for E85(biofuel) instead of Petrol. Still the actual gain obtained even surprised the enthusiastic engineers at Koenigsegg.

Following the long term strategy of Koenigsegg, all previous CCXs will have the possibility to be converted by the factory to accept the biofuel option and reap the performance and environmental benefi ts of this wonderful and eco friendly fuel.

The CCXR Biofuel upgrade has been developed in-house on the factory's engine dyno by the skilled technicians at Koenigsegg, led by Christian Koenigsegg, Marco Garver and Anders Hoglund from the Koenigsegg partner company Cargine Engineering.

Curiously enough the CCXR is the first homologated car currently in production to reach over 1000 BHP.
