The Koenigsegg CC 8S


Koenigsegg is a small Swedish manufacturer that builds some of the most exclusive supercars in the world. It has updated its V8 supercar for 2002. The new CC S8 features lights that are now held in a single unit instead of triple unit clusters compared to the 2002 CC. the rear wing also gone, which is now optional. The first red Koenigsegg CC 8S was delivered to its' owner following the 2002 Geneva Motor Show.

The body and chassis of Koenigsegg CC are made of autoclaved epoxy pre-impregnated carbonfiber. The car is enabled to be extremely strong, lightweight and completely resistant to corrosion through the use of this material. Composite engineers with experience from Formula One racing are the one who designed the chassis. The chassis features a fully semi-monocoque self supporting center unit, which offers both world class rigidity and driver safety. It also has 21 layers of carbonfiber that varies between unidirectional and woven material, with the middle spacing of aluminium honeycomb, as well as the incorporated tool grade solid aluminium joining points. A mere 62 kg is the total weight of the semi-monocoque.

The engine is mounted on the top of a machined aluminium dry sump unit that also acts as a supporting beam for the rear subframe. The Cima gearbox and supports the power transmission and suspension systems are contained in this milled aluminium subframe. The chromemolybdenium rods that are bolted to the chassis kept it rigidly in place. This car has specially developed semi-stressed supercharged and intercooled Quad Cam 4 valve 4.7l V8 engine that delivers 655 smooth horsepowers at 6,800 rpm and 750 nm of torque at 5,000 rpm. Through the use of carbonfiber, titanium and aeroplane specified aluminium alloy it achieved its very low weight of only 240 kg. Compared to conventional materials, the carbonfiber valve and timing covers save about 12 kg. It is ideal for use in a super car when combined with its small outer dimensions.

The centrifugal supercharging system is attached to a large size intercooler, which manages to lower the charged intake air temperature from 150 degrees C to a mere 60 degrees C, allowing for a 1.2 bar boost pressure with a compression ratio of 8.6:1, with lightweight carbonfiber ducts and end-tanks. The gearbox that is specially developed by Cima relies heavily on experience from racing, even Formula One. The strongest and most reliable transaxle gearbox ever built for a mid engine car is probably the 6 speed gearbox. Since it incorporates an internal oil pump for reliable lubrication, and a large oil cooler, the 6 speed gearbox can take the strain from the brutal force of the engine. Close to 400 km/h at 7300 rpm is the calculated speed that the final gear ratio can do to propel the car.

The body of the Koenigsegg CC 8S has been designed for the purpose of incorporating the unique easy access removable and stowable hardtop. The lightweight carbonfiber roof pane is unlocked by pulling two handles from within. The removal of hardtop is now easy and can be placed in the front luggage compartment, where it fits perfectly. The mid engine longitudinal and 6-speed manual Koenigsegg CC 8S is very unique among other supercar. Its appearance is really impressive with its highly advanced opening and closing technology and excellent aerodynamics! However, this car is not anymore in production today.

Wow! Really amazing for me! I can’t really imagine having this super exotic car and driving along the city and countryside with all the people looking at me with surprised messages.
