2004 Koenigsegg CCR

CCR is the extreme version of the CC, a supercar made by the Swedish manufacturer, Koenigsegg. Now, ten years after the project’s inception, the CCR exhibits several technological improvements to engine, chassis and body. As a result, the CCR has become the fastest production car ever, as proved by a recent run around Nardo proving grounds.

Record Nardo Run

February the 28th 2005 – Driven by Loris Bicocchi, the Koenigsegg CCR broke the production road car speed record, achieving a new official top speed of 388 (387.87) km/h at Italy’s Nardo Track. Thus, the CCR has broke the official McLaren F1 record of 386.7 km/h, which was set using a prototype called the XP5.

Koenigsegg say the CCR was ‘technically standard’, having tires, ride height, engine configuration, wheel geometries, gearbox, clutch, brakes, boost pressure matching the production car’s specification. The record run was celebrated at the 2005 Geneva Motor Show, where both the record car, joined by a silver counterpart were on display. Since that time, the CCR has been approved for inclusion into the Guinness Book of World Records.

In Brief: The CCR

The CCR’s performance has been increased mainly due the development of the CCR engine, which sports a new Lysholm supercharger and titanium exhaust. These components help engine’s power reach 806 hp (601 Kw), while maintaining a torque curve that has high figures over a broad revolution band.

Power aside, the CCR is distinguished outwardly by its boldly shaped side air apertures and front splitter. Also included are larger brakes, new racing shock absorbers, a monocoque carbonfibre intake plenum, the CCR advanced throttle and the larger 19 inch front wheels. These modifications all contribute to place the CCR at the very top among supercars.

Lysholm Twin-Screw Compressor

The Koenigsegg CCR engine is equipped with a Lysholm Screw Compressor, which has several advantages to the common centrifugal compressor. It creates a higher boost-pressure at lower rpm, thus increasing both acceleration and control at low speed. Lag time during shifts and on-off throttling are reduced to a minimum.

The twin screw principle is also highly energy efficient, which contributes to the extreme power and torque of the CCR machine. Boost-pressure in the CCR carbonfibre plenum reaches levels as high as 1.3 bar, considerably higher than that of any competitor. The Lysholm supercharger is the alone on the market today to combine both a positive displacement design for maximum low-end torque and highly effiecient top-end horsepower output. Also emission levels at high speed and boost are lower than with other turbo- and supercharging systems.

VPS Shock Absorbers

To further enhance the unmatched road holding and handling of the Koenigsegg suspension set-up, the CCR is equipped with new shock absorbers, custom built and developed for the Koenigsegg CCR by VPS, Italy. These shocks are produced only in small series for racing purposes and have the advantage of greater adaptability and lower weight than any other on the market. These superb shocks also allow extensive fine tuning to suit the racetrack or driver preferences. Koenigsegg test driver Loris Biccochi, world-renowned for his expertise in motoring, has personally participated in the development of the CCR shocks. Their appearance is equally striking; all parts are of machined metal, the surface is of titanium coloured anodized aluminium.

CCR Cylindrical Throttle

The Koenigsegg team of engineers has implemented Formula One technology in the construction of the Koenigsegg CCR Cylindrical Throttle. It is a vital part of their effort to optimize intake air flow to the engine and reduce drag to a minimum. The amount of intake air is controlled by the precise rotation of a cylinder, through which an oval channel leads air into the plenum. This unique barrel-design greatly increases the sensitivity and response at low-end throttling, while at the high-end the perfectly unobstructed flow of air generates a higher horsepower output. It has been developed to work in perfect harmony with the Lysholm Screw Compressor, which creates such a high boost-pressure as to make ordinary throttles unstable. The massive metal cylinder is also very effective in dampening the whistle-like sound from the compressor below certifiable levels. For patent reasons we unfortunately cannot exhibit any images of this device.

Carbonfibre Air Intake Plenum

The Koenigsegg CCR engine incorporates an air intake plenum chamber made of carbonfibre. It was designed and modelled by Koenigsegg engineers exclusively for the CCR. It helps to increase the engine’s perfomance in a number of ways; it lowers the weight of the car by around 11 kg, it provides a more aerodynamic flow of air into the engine and moves the pressure centre closer to the cylinders, thus decreasing throttle lag time. The plenum is shaped to allow a stream of cooling air pass between it and the engine block in order to keep the charged intake air as cool as possible.

Titanium Exhaust System

The CCR has a full titanium exhaust system. Besides the aestetic splendour of this multi-coloured shimmering metal, it brings several advantages to this record-braking supercar. Titanium is a material with the strength of steel and the lightness of aluminium, yet it is virtually insensitive to high temperature. Using this exquisite metal enables the construction of an exhaust system out of very thin material without adding extra heat insulation, which adds to the efficiency of the catalytic converters.

The CCR Titanium Exhaust weighs less than half of its stainless steel predecessor. It is also slightly refined both in the design of the manifolds and the position of the cats, in order to further minimize drag. This unmatched exhaust system was designed and developed by Koenigsegg and the titanium parts are custom made exclusively for Koenigsegg in Sweden. The brutal yet sophisticated roar of the CCR ows much to this exhaust, the very hard and thin metal emits a crystal clear interpretation of that wonderful noise.

CCR Brakes

The Koenigsegg CCR brakes are specially developed for the model by AP-Racing. They feature a new technology that ensures perfectly intact braking capacity despite the unavoidable termal shifts in the brake-disc. The discs are not mounted in a fixed position to the wheels, but are allowed to move a fraction of a millimeter in all directions, i.e. what is called floating mount. This serves to absorb any termal shift, which in combination with the Koenigsegg brake ventilation system makes the brakes exeptionally stable at any driving (racing) condition. Koenigsgg has chosen to go against the currently trendy ceramic or ceramic-composite discs. Such materials are new and exiting, but has as of yet not proven neither as reliable nor as subtle as using steel alloy for brake discs.

CCR Aerodynamics

The body of the CCR shows some new features when compared with the CC 8S. Most notable are the redesigned side air intakes and the new headlights. The air intakes’ new shape is an improvement both aestetically and aerodynamically. This design allows more air to be pulled into the cavity and increases the air pressure on the actual cooler, which makes the oil cooler and intercooler work more efficiently.

The CCR is also equipped with a front splitter made of carbon fiber. It funcions as a dividing plane that determines which part of the air-flow that shall pass above or below the vehicle. The purpose is to better define the jetstream that rushes in under the car and builds up the venturi effect, which glues the car to the ground. A fluctuating or turbulent such jet-stream causes the downforce to be unstable, which can result in a loss of road holding during high speed cornering. This discrete splitter is also designed to increase frontal downforce, both by pushing more air upwards and toward the sides and by prolonging the curvature of the integrated wing on the underside of the bumper. Airpressure on the main radiator and brake cooling inlets is also greater,which further enhances the excellent performance of the Koenigsegg CCR.

For racing purposes Konigsegg has developed the Twin Fin Wings, a pair of triangular fin-like wings made of carbon fiber. They are mounted horizontally on the rear hood and leaves a gap between them to allow the driver better rear view. They can easily be removed if the drives so prefers. Their purpose is to increase rear downforce, which is not necessary in other than the extremest of racing circumstances, since the design of the rear hood with its integrated wing in itself provides sufficient downforce. These wings are therefore a customer option, and they are delivered colored or in clear-coat carbon according to the buyer’ s choice.
