The CCX is the latest vehicle in the Koenigsegg CC range. The Koenigsegg CCX is practically a new car, as its engineering was completely redesigned in many respects to comply with US regulations. This is due to a high demand from that market.
This complex redesign process represented a great challenge for the Swedish brand team, who worked hard to maintain the exterior shape of the car. They considered it extremely important to avoid the change in the aerodynamic silhouette of the CC range.
The acronym CCX stands for “Coupe de Competitions X”. The Koenigsegg CCX commemorates the tenth anniversary of the first test drive of the first CC prototype. This test carried out in 1996 saw the birth of this Swedish car, which today enjoys well-deserved recognition in the environment.
Of course, the CCR also enjoys a Guiness record as the fastest production car in the world, reaching 395 km/h in 2005.
Both the body and the interior of the Koenigsegg CCX contain new parts. With a new front bumper design, designed to pass the rigorous bumper evaluation, the CCx incorporates other modifications including brake cooling, fog lights and side position lights as required by US rules. The front lights have been slightly redesigned to meet the new bumper line.
Side skirting panels allow for greater downforce by increasing the area under the body. The new car exterior has been created using Icem Surf CAD software, industry leading software. With this technology, Koenigsegg tries to ensure the highest level of refinement in details such as the joints between parts.
The car is 88mm long as a result of modifications made to comply with U.S. rear impact regulations. This also served to free up space around the silencer. The engine cover is now actually a glass window over the new impeller.
The Koenigsegg CCX offers as an optional ceramic disc brakes, 382 mm in diameter for the front wheels and 362 mm on the rear wheels. These brakes feature 8-piston jaws at the front and 6 at the rear. Each ceramic brake disc is 2 kilograms lighter than standard ones.
Another innovation that sets a precedent, as its first application in the market, is the optional carbon fibre rims. Again, each carbon rim is 3 kilograms lighter than magnesium alloy. Thus, the CCX saves 5 kilograms per wheel, becoming the super car with the lowest weight leaning on the ground. This is a way to differentiate the suspended mass from it makes contact with the ground.
The semi-monocoque chassis is constructed of pre-impregnated carbon fiber combined with honeycomb and Kevlar. This use of aerospace technology, increasingly applied in cars, allows to maintain low weight, reduce size while maintaining optimum structural rigidity for handling and extremely high impact effectiveness.
In the aerodynamic aspect the advance also surprises. Side air intakes drive the air flow to the center generating a high pressure zone, achieving something that few sportsmen achieve without placing an air intake on the roof.
Perhaps the most shocking thing about the work done on this engine is that they managed to adapt it to 91 octane fuel and California's strict pollution standards without sacrificing their original power. For this purpose, the cylinder heads were redesigned, adding more area for valve actuation.
Other modifications include the new camshafts and the use of smaller double fuel injectors. The fuel tank was also replaced by a new one.
The optimized Koenigsegg V8 engine features two superchargers. It has four valves per cylinder and double camshaft (DOHC). With 4,700 cm3 engine capacity and a compression ratio of 8.2 to 1, the 806 hp impeller accelerates the CCX from 0 to 100 km/h in 3.2 seconds and allows it to develop a top speed of 395 km/h.
+ Central engine V8 4.700 cm3 + 2 twin superchargers (1.2 bar) + 32 valves (DOHC) + Compression ratio: 8.2 to 1 + Power 806 hp at 6.900 rpm + Maximum torque: 678 lbs ft at 5,700 rpm + 6-speed manual gearbox + Automatic clutch + Rear wheel drive
