The CCXR is a more "environmentally friendly" version of the CCX, powered by the same engine, but converted to use E85 and E100 ethanol fuel, as well as standard 98 octane petrol [REF].
At the 2008 Geneva Motor Show Koenigsegg presented two special edition models, the CCX Edition and the CCXR Edition, both fitted with a remapped, 4.8 L twin-supercharged V8 engine and limited to 2 and 4 units respectively [REF].
