ACO and FIA regulations for the GT1 class. The CCGT's engine is based on the unit used in the Koenigsegg CCX with the superchargers removed and the capacity increased to 5.0 L to compensate for the loss of power. The CCGT had over 600 kg downforce and over 600 hp normally aspirated, racing restricted hp. Due to the already lightweight construction of the road-going model it was based on, the weight was easily reduced under the minimum , which means that the Ballast can be placed optimally in order to meet the mandatory weight. Two months after the car completed its first shakedown runs, the FIA GT1 regulations were suddenly changed, according to the altered regulations, carbon monocoques were disallowed and there had to be a minimum of 350 road cars produced per year of the model that was to compete, something that Koenigsegg was unable to achieve, prohibiting the CCGT from racing. Production The CCX was produced between 2006 and 2010 and the total production amounted to 49 cars (30 CCX, 9 CCXR, 6 CCX/CCXR Edition, 2 CCXR Special Edition and 2 CCXR Trevita). One of them was a CCX used for Crash tests and the other was a CCXR which is still a factory test car. Some CCX cars have later been upgraded to CCXR-specifications.

The car originally lapped the circuit in 1:20.4, but was then fitted with an optional rear wing to provide downforce after The Stig spun it off the track at 130 mph due to a power steering failure. The Stig purportedly recommended this modification, predicting that the car would then be the fastest ever round Top Gear's track<ref name="topgear81"> – Jeremy Clarkson: "After the accident, Stig said he reckons this car would be 4 seconds faster than it was if it had a big wing on the back."</ref> but Koenigsegg later stated that the improvement was due to adjustments to the chassis and suspension settings and not the addition of the rear spoiler. Despite this, the Stig's spoiler-idea remained the credited reason for the improved lap time. The name of the car
