The CCGT came about as side project for Christian and the engineers at Koenigsegg. When Christian started to build and design the first CC prototype, racing was always part of the larger picture. Hence Christian studied the ACO Le Mans regulation and made sure that his car would fit the regulation for one for the most interesting racing categories at the time – the GT1 Class. Here the regulation stated that the car is not allowed to be wider than 2 meters and that the cockpit has to have at least 70% of the width of the car. So Christian designed the car to these exact measurements so that the road car would be a perfect basis for a GT1 car.
The few people that have driven the CCGT state it handles like a dream and that it would have been very competitive. – The reason why it never went racing? Two months after Koenigsegg started the first shake down runs of the first CCGT, ACO and FIA changed regulations for the GT1 class. Carbon monocoques were no longer allowed and minimum production numbers went from a total of 20 cars over several years to 350 cars per year! Good night! The CCGT is truly one of the rarest most exiting Koenigsegg cars ever made and the sound is just fantastic.
