The Koenigsegg CCX is a mid-engined roadster from Swedish car manufacturer Koenigsegg. The CCX has been engineered to comply with the US regulation and and is an evolutionary design that replaced the Koenigsegg CCR.
CCX is an abbreviation for Competition Coupe X; the X commemorating the 10th anniversary, (being the Roman numeral for ten), of the completion and test drive of the first CC vehicle in 1996.
The CCX was first unveiled on February 28, 2006 at the 2006 Geneva Motor Show although its existence was announced earlier. A derivative known as the CCXR is available, the difference being that CCXR's engine is tuned to run on biofuel. The different fuel and tune allows the CCXR to produce 25% more power than the CCXThe 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 259 mph (417 km/h), although this has not been officially verified. On 15th June 2008, a standard fully equipped CCX was independently timed by While previous Koenigsegg models were powered by a Ford Modular V8 engine sourced from the U.S., the engine of the CCX was designed by Koenigsegg based on the Ford Modular architecture, and assembled for them by Grainger & Worrall, a British company that produces drivetrain components for Formula One cars. The engine is a 4.7 litre 288 cu in (4,719 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 (121 kPa)of boost with an 8.2:1 compression ratio. The engine produces 806 bhp (601 kW; 817 PS) at 6900rpm and 678 lb·ft (919 N·m) of torque at 5700 rpm on 91 octane (U.S. rating) .The engine is lubricated with a dry sump system with a separate oil pump, the pistons are cooled by oil sprayed onto them and the oil itself has an external cooler.The CCX engine burns 14 mpg-US (17 L/100 km; 17 mpg-imp).SportAuto in achieving a record 0-186-0 mph (0-300-0 km/h) in 29.2 seconds, beating SLR McLaren 722, Lamborghini Murcielago LP640, Porsche 997 GT2, Alpina B6 S, Corvette Z06The CCX is a two-door targa top and the removable roof can be stored under the front trunk meaning that, unlike many of its competitors, it can be changed at any location, not only one where the roof can be safely left.The body, made of pre-impregnated carbon fiber and Kevlar, is 169 in (4,300 mm) long, 78.6 in (2,000 mm) wide and 44.1 in (1,120 mm) tall with a ground clearance of 3.9 in (99 mm). As with all previous Koenigsegg models, the "dihedral synchro-helix" actuation doors rotate forward and upwards similar to scissor doors though the Koenigsegg design avoids the problem of the open door obscuring the passenger's entry or exit.
The CCX has a frontal area of 2,894 sq in (1.867 m2) and a drag coefficient of just 0.30. It also has a flat underside with venturi tunnels at the rear and an optional rear spoiler to improve aerodynamics. Between the 2 speedster humps (humps behind the seats) is a vortex generator used as a ram-air intake that allows higher pressure in the air box without a roof scoop that would increase the frontal area. At 124 mph (200 km/h) there is 132 lbf (60 kilograms) of downforce over the front axle and 143 lbf (65 kilograms) over the rearThe CCX has a six speed manual gearbox made for Koenigsegg by Cima with a twin plate clutch of diameter 8.5 inches (220 mm) as default but a sequential manual transmission option is available. The power is fed to the wheels through a torque sensitive, limited slip differential.The option to select gear ratios is available, but the default ratios of the 2007 CCX can be seen in the table belowThe standard CCX wheels are Koenigsegg's magnesium alloy wheels, though the option to upgrade to carbon/magnesium wheels which each weigh 6.6 pounds (3.0 kg) less than the standard wheels is available. The front wheels have a diameter of 19 inches (480 mm) and the rear, 20 inches (510 mm). Each of the wheels is attached by center locking wheel nuts. The car comes with Michelin Pilot Sport 2 unidirectional tires with asymmetric tread. The front tires have codes of 255/35 Y19 and the rear 335/30 Y20.
The front and rear cast iron disc brakes are 14.3 in (360 mm) across with 1.3 inches (33 mm) of contact at any point and have 6 piston calipers. The brakes can be upgraded to carbon ceramic brakes which weigh 4.4 pounds (2.0 kg) less per wheel, a diameter of 15 in (380 mm) with 1.3 in (33 mm) of contact and eight piston brake calipers.
