A previous model manufactured by Koenigsegg is the CCX that succeeds the 806 horsepower (hp) CCR, which held the Guinness World Record for the most powerful streetcar. Though the CCXR and the CCX are similar in some of their performance figures, such as reaching a speed of 100km (62mph) in 3.2 seconds, the new CCXR has a higher top speed.

The CCXR's body is made of pre-impregnated carbon-fibr/kevlar and of lightweight sandwich reinforcements. It is equipped with a Koenigsegg V8 cast aluminum engine, 4 valves per cylinder, and double overhead camshafts. The CCXR's transmission is a 6-speed gearbox that was specially developed by the Italian company Cima. 

According to Keonigsegg, the CCXR's performance is even better than that of the standard CCX thanks to the bio-fuel, "the ethanol in bio-fuel 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." The company explains that for this reason, the power reaches up to 1018 hp at 7200 rpm, and the torque can reach up to 1060 nm at 6100 rpm. 

The company also stated that is will be possible to return all previous CCXs to the factory, where they will be converted to operate on bio-fuel. This will not only upgrade the cars' performance but will also make them more environmentally friendly.

TFOT recently covered Honda's "PUYO" – a car that was designed to be a corner-less, soft box that is both friendly to the environment and pleasant to the touch. Another 'green' vehicle covered by TFOT is the Fusion Hydrogen 999 - Ford's 500-horsepower fuel cell race car, which broke the land speed record at the Bonneville Salt Flats.
