» Koenigsegg Competition Coupe GT Bio-fueled CCXR
(March 2007)

To comply with FIA GT1 series regulations, Koenigsegg were forced to reduce the output of its 806hp CCX to the tune of 600hp. To do this, engineers removed the standard car’s superchargers but bored out the 4.7L V8 engine to 5.0L. Labeled the CCGT, the new race car also undercuts the FIA’s minimum weight restrictions by 100kg thanks to its already super-light structure. Finally, further development of the car’s aerodynamic package was required due to its short overhangs, which are actually worse for generating downforce.

Koenigsegg have also developed a bio fuel powered CCXR with even more performance than the standard CCX. The burning of ethanol in biofuel has the positive side effect of cooling the combustion chambers. This combined with a higher octane rating provides the enviro-friendly supercar with 1018hp at 7200rpm and peak torque of 1060Nm at 6100rpm, making it the first homologated car currently in production to reach over 1000hp.

Previous customers will be able to have their CCXs converted by the factory to accept the biofuel option and reap the performance and environmental gains as well.

Press Release:

Competition Coupe GT
DOWN TUNED TO 600+ HP in order to comply with race regulations.

Koenigsegg has created a new race car - the CCGT, based on the production CC-model range. The CCGT complies with the ACO and FIA GT1 regulations.

The CCGT engine is based on the Koenigsegg CCX production engine with the superchargers removed but enlarged to 5.0 litre.

The reliability of the race engine is expected be exceptional as it is based on the proven strength and durability of the signifi cantly more powerful road car engine.

The minimum weight allowed for a GTI race car is 1,100 kg and most manufacturers struggle to meet this target, having to undergo massive weight saving programs.

Due to the fact the Koenigsegg CC cars are very light and stiff in road confi guration, the racing CCGT weighs in at just under an astounding 1,000 kg. This gives the possibility to place 100 kg of ballast freely within the car structure, still following the set rules. This should give Koenigsegg an interesting advantage over the competition.

The CCGT has very short overhangs, which could be seen as an issue when it comes to generating enough downforce. However, by further developing the clever and "slippery" design concept of the CC range, Koenigsegg believes they have created a unique package incorporating a surprising amount of down-force combined with a very compact package and optimal weight distribution. Since the CCGT has a short overall length and low overall height, whilst still maintaining adequate track width and length, it is thereby gifted with superior agility compared to most of the competition, which should be evident in future heated racing combats.

The Koenigsegg CCGT development team, headed by Dag Bölenius, has done a superb job by refining the CC into the CCGT.

The race engine is being developed in-house in parallel with the production units by Koenigsegg engineers, supported by Anders Hoglund from Cargine engineering and JP Motorsport.

Flower Power
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.
