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 an in-house developed 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 Coupé 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 in-house developed 4.7 L twin supercharged V8 engine capable of producing 806 PS (593 kW; 795 hp) at 7000 rpm and 920 N⋅m (679 lb⋅ft) at 5700 rpm of torque while running on 91 octane gasoline. 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 the other was a CCXR which is still a factory test car. Some CCX cars have later been upgraded to CCXR-specifications.
The new engine is of all aluminium construction, made out of 356 aluminium with a T7 heat treatment to further enhance block integrity and cylinder bore chill during casting. Specifically created and casted for Koenigsegg by Grainger & Worrall, a casting specialist with F1 experience in drivetrain components, the engine is built, assembled and tested at their Ängelholm production plant The engine is lubricated with a dry sump system with a separate oil pump and the pistons are cooled by means of an internal cooler that sprays oil onto them in order to run high cylinder pressure with 91 octane fuel making it capable of 14 mpg (17 l/100 km) in combined cycle and 18 mpg (13 l/100 km) in highway travel. Available transmissions are a CIMA 6-speed manual and a 6-speed sequential manual transmission. Power is fed to the wheels through a torque-sensitive limited slip differential.
The chassis is made from carbon fibre reinforced with kevlar and aluminium honeycomb like the previous models. 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 patented head lamps, 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 (1.867 m2) and a drag coefficient of 0.30. with a CdA of 0.56 m2 (6.0 sq ft). It also has a flat underside with venturi tunnels at the rear and an optional rear spoiler to improve downforce. 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, there is 51 mm (2 in) of extra headroom as well as specifically designed Sparco carbon fibre seats.
Wheels and brakes
First in the industry carbon fibre wheels are optional equipment, 3 kilograms (6.6 lb) lighter than the standard forged alloy telephone-dial wheels,both using center locking nuts. Diameter is 19 inches at the front and 20 inches at the rear equipped with 255/35 Y19 front, 335/30 Y20 rear Michelin Pilot Sport 2 tires, 8 piston caliper carbon ceramic brakesmeasuring 380 mm (15 in) in diameter at the front and 6 piston caliper 362 mm (14.3 in) at the rear are optional, saving another 2 kilograms (4.4 lb) of unsprung weight.
In order to compete in the FIA GT Championship Koenigsegg created the CCGT race car, based on the production CC model range; making its debut appearance at the 2007 Geneva Motor Show and built to comply with the ACOand 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. Due to the already lightweight construction of the road-going model it was based on, the weight was easily reduced under the minimum 1,100 kg (2,425 lb), which means that the Ballast can be placed optimally in order to meet the mandatory weight.
As the car neared completion, the FIA GT1 regulations were suddenly changed, according to the altered regulations, 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.
Koenigsegg CCX Top Gear
In 2007, the CCX was the fastest car to complete Top Gear's Power Lap with a time of 1:17.6 (until it was beaten by the Ascari A10 with a time of 1:17.3).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 130mph 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 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 on the lap board as "Koeniggggsenisseggsegnignigsegigisegccx2 with the Top Gear wing", reportedly because none of the Top Gear Presenters knew how to spell Koenigsegg, and also poking fun at the long and hard pronunciation of the manufacturer's name.
