The Koenigsegg CCX is a mid-engined sports car built by Koenigsegg Automotive AB. The project began with the aim of making a global car, designed and engineered to comply with global safety and environment regulations, particularly to enter the United States car market. To sell cars in the US many alterations were made to the design of the CCR; the previously used Ford Modular engine was replaced by a Koenigsegg engine designed to run on 91 octane fuel, readily available in the United States, and to meet the Californian emission standards. The name CCX is an abbreviation for Competition Coupe X, the X commemorating the 10th anniversary (X being the Roman numeral for ten) of the completion and test drive of the first CC vehicle in 1996. The CCX was unveiled at the 2006 Geneva Motor Show, sporting body modifications to meet US regulations and a new 4.7 L twin supercharged V8 engine capable of producing 795 hp at 7000 rpm. There were 49 CCX-Series cars produced between 2006 and 2010 (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 one is still a factory test car. CCX cars have later been upgraded to become CCXR-spec.

The chassis is made from carbon fiber reinforced with kevlar and aluminum honeycomb like previous models and while the body keeps the targa top body style and the "dihedral synchro-helix" actuation doors, it is completely reworked. There is a new front bumper design, enhanced brake cooling, fog lamps, US position lights, a new fresh air intake on the bonnet that acts as ram air booster, air intakes behind the front wheels to enhance airflow and a glass window over the engine. The CCX has frontal area of 2,894 sq in and a drag coefficient of 0.30. It also has a flat underside with venturi tunnels at the rear and an optional rear spoiler to improve aerodynamics. At 200 km/h (120 mph) there is 60 kg of downforce over the front axle and 65 kg over the rear. The car is 88 mm (3 in) longer to comply with the US rear impact regulations and to free space around the rear muffler. On the interior side, there is 51 mm (2 in) of extra headroom as well as specifically designed Sparco carbon fiber seats. First in the industry carbon fiber wheels are optional equipment, 3 kilograms (6.6 lb) lighter than the standard forged alloy wheels, both using center locking nuts.
