Koenigsegg CCX

Description

The CCX can accelerate from 0--62 mph (100 km/h) in 3.2 seconds and from 0--124 mph (200 km/h) in 9.8 seconds. According to Koenigsegg it has a top speed of approximately 250 mph, although this has not been officially verified. On 15 June 2008, a standard fully equipped CCX was independently timed by sport auto in achieving a record 0-186-0 mph (0-300--0 km/h) in 29.2 seconds, beating the Mercedes-Benz McLaren SLR 722 Edition, the Lamborghini Murciélago LP640, the Porsche 997 GT2, the Alpina B6 S (based on the BMW 6 Series), and the Corvette Z06. While previous Koenigsegg models were powered by Ford Modular V8 engines sourced from the US, the engine of the CCX was thoroughly re-engineered by Koenigsegg themselves and is assembled at the Koenigsegg factory, though it is still based on the Ford Modular architecture. The engine block is cast for them by Grainger & Worrall, a British company that produces drivetrain components for Formula One cars. The engine is a 4.7 liter 288 cu in (4719 cc) V8, with dual overhead camshafts and 4 valves per cylinder. The engine block is made of 356 Aluminium that has undergone a T7 heat treatment, a form of accelerated precipitation strengthening. The aluminium alloy is stronger than the previous engine and allows a thinner, thus lighter, engine block that will withstand higher cylinder pressures. The engine is boosted by two centrifugal superchargers that provide 17.5 psi (1.2 bar) of boost with an 8.2:1 compression ratio. The engine <b>...</b>
