The Koenigsegg CCX is powered by a hand built, Koenigsegg designed, twin supercharged, all aluminum and carbon fiber, eight cylinder engine.
Its pure racing performance power and torque have been achieved whilst maintaining the low weight and superb drivability of the car. The CCXR version is the most powerful production engine in the world and only weighs 198 kg.
It is a state-of-the-art DOHC semi-stressed V8 construction with a 4.7 litre displacement and 32 valves, with drysump lubrication. The CCX is boosted to its extreme power output by a unique Bi-compressor Supercharging system, which employs twin centrifugal compressors to enable a 1.6 bar maximum boost pressure at 7000 RPM. This system significantly increases power and torque across a broad rev band, and it also includes the revolutionary Koenigsegg RBC-System (Response Boost Control) (patented), which takes out on-off throttling lag time.
Koenigsegg also has developed its own proprietary Catalytic converter systems, which enables the cars to met even the stringent California emission regulations. The Catalytic converter sits very close to engine, for early light of and has a special blend of precious metals and cell structure that reduces back pressure while maintaining full catalytic effect over a long period of time. This technological feat cannot be overstated; no competitor has come close of creating an engine configuration with a power output of as much as 1018 Hp, yet still keep exhaust gas emissions below certifiable levels.
