The Koenigsegg CCX
The Koenigsegg CCX started off with in a small factory somewhere in the middle of Sweden and it was a project which was from the start seeking for the world to take notice. The guys at Koenigsegg knew that they had to take hold of the US car market and as a result the car was designed based on this basis. From the onset the car had a focus on this market and did everything to make sure that the regulations for them to be able to sell in the US were met.
The inner workings of the CCX
Although the car had been in development for a long time the unveiling of the car only came in 2006 at the Geneva Motor show. The car had a very performance based body shape that was specifically designed to meet US regulations and it also had an in house built engine. The motor was a huge 4.7 liter twin supercharged V8 which reved like a smaller engine but had enough torque to pull a truck. The big V8 produced 795 hp and it was capable of speed that were just too dangerous to the point that the car was electronically limited.
When it came to power the designers at Koenigsegg could not get enough of it and as a result they simply could not use anyone else's motor. They ended up custom building their own motor which was constructed from an all aluminum composite. The block was heat treated to ensure that it could withstand the massive amount of heat and pressure from those twin superchargers and still be able to keep its integrity. The power plant is built and tested off site and goes through stringent tests that are akin to F1 testing procedures for engines. The cars dry sump system enables the octane fuel that it uses to become more economical and as a result on the open road this car is capable for 18 mpg, and for a car this powerful this is a massive achievement. To deal with this amount of power the car had to have a torque sensitive limited slip differential to counteract the likeness for the wheels to spin in flat out turning situations.

As the car needed to be as light and as strong as possible there was only one material that would suffice for the designers at Koenigsegg and thats carbon fiber. No only was the chassis made for the lightest/strongest material put on a road going vehicle the carbon fiber itself was reinforced to make it stronger with kevlar and aluminum honeycomb composites to ensure that the body could withstand the punishment that the car would go through. The car also featured a very lean and low slung double bubble roof which improved aerodynamic efficiency. Multiple air intakes helped to keep the engine cool as it was mid engined layout. To improve upon the already aerodynamic body there was a smooth finish applied to ever CCX which allowed the car to create a drag coefficient of only 0.30, this aerodynamic efficiency was only spoilt by the need and application of the rear spoiler which allowed car be somewhat controllable at high speed in the corners.
With all the speed that the CCX commands it would not have been cleared to be sold in most countries without the brakes being on point. The car offers carbon fiber wheels as an option with this option being around 5 kgs lighter than standard alloy wheels. The brakes themselves are carbon ceramic brakes which means that the material that they're made out of will make it virtually impossible for them to fade under heavy use.
After the success of the reveal in 2006 there began works to have another more aggressive version of the CCX this was to be powered by the same engine. Although the power plant was the same the car did not only run on the standard octane petrol but it was also able to burn ethanol fuel. The car burned fuel more economically due to its modified fuel injectors and upgraded piston rings which helped increase the power to a 1000 horsepower. This amount of power is only available if the car is running on the ethanol fuel. Although there were some minor differences between the CCX and the CXXR , most of it was virtually the same to its predecessor.
Motorsport and Legacy
A track version of the CCX was made to compete in the FIA GT Championship the car that resulted was named the CCGT. Although it was based on the CCX the car had been changed to further suit the needs of racing conditions. The car featured a bigger engine and as result of trying to stamp out flat spots in the rev range the cars superchargers were removed. The weight of the car was already very low and due to this the car easily met weight regulations. Unfortunately for Koenigsegg the rules for competing in GT1 changed and as a result the CCGT was not able to compete in races.
