Crossflags's 2008 Koenigsegg CCX

ONE BAD AZZ RIDE

About this Dream Vehicle:

Specifications

Performance
The CCX can accelerate from 0–100 km/h (62 mph) in 3.2 seconds and from 0–200 km/h (124 mph) in 9.8 seconds.[1][9] According to Koenigsegg it has a top speed in excess of 395 km/h (245 mph), although this has not been officially verified.[1] On 15th June 2008, a standard fully equipped CCX was independently timed by SportAuto in achieving a record 0–300–0 km/h (0–186–0 mph) in 29.2 seconds, beating SLR McLaren 722, Lamborghini Murcielago LP640, Porsche 997 GT2, Alpina B6 S, Corvette Z06.[10][11]


Engine

The engine of a Koenigsegg CCX at the 2006 Geneva Motor ShowWhile 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.[8][12] The engine is a 4.7litre 4,712 cc (288 cu in) V8, with dual overhead camshafts and 4 valves per cylinder.[1][8][13] The engine block is made of 356 Aluminium that has undergone a T7 heat treatment, a form of accelerated precipitation strengthening.[8][14] 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 increase the compression to 17.5 psi (121 kPa) with an 8.2:1 compression ratio. The engine produces 806 bhp (601 kW) at 6900rpm and 678 lb·ft (919 N·m) of torque at 5700rpm on 91octane (U.S. rating) gasoline.[1][9] 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.[1] The CCX engine burns 14 mpg–U.S. / 17 mpg–imp (17 Liters per 100 kilometers).


Exterior

A CCX at the 2006 SEMA car show in Las VegasThe 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.[1][7] The body, made of pre-impregnated carbon fibre and Kevlar, is 4,293 mm (169.0 in) long, 1,996 mm (78.6 in) wide and 1,120 mm (44 in) tall with a ground clearance of 100 mm (3.9 in).[1] 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.[15]

The CCX has a frontal area of 1.867 m² (2,894 sq in) and a drag coefficient of just 0.3.[1] It also has a flat underside with venturi tunnels at the rear and an optional rear spoiler to improve aerodynamics.[1] 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.[8] At 200 km/h (124 mph) there is 60 kilograms (132 lbf) of downforce over the front axle and 65 kilograms (143 lbf) over the rear.[13]


Transmission
The CCX has a six speed manual gearbox made for Koenigsegg by Cima with a twin plate clutch of diameter 215 millimetres (8.5 in) as default but a sequential manual transmission option is available. The power is fed to the wheels through a torque sensitive, limited slip differential.[1] The option to select gear ratios is available, but the default ratios of the 2007 CCX can be seen in the table below.[6]

Gear 1 2 3 4 5 6 Reverse Final Drive
Ratio[16] 2.875:1 1.652:1 1.125:1 0.865:1 0.711:1 0.604:1 3.000:1 3.545:1


Wheels and brakes

The standard magnesium-alloy rear wheel of a CCXThe standard CCX wheels are Koenigsegg's magnesium alloy wheels, though the option to upgrade to carbon/magnesium wheels which each weigh 3 kilograms (6.6 lb) less than the standard wheels is available.[8] The front wheels have a diameter of 480 millimetres (19 in) and the rear, 510 millimetres (20 in). Each of the wheels is attached by center locking wheel nuts.[1] 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.[1]

The front and rear cast iron disc brakes are 362 mm (14.3 in) across with 32 millimetres (1.3 in) of contact at any point and have 6 piston callipers. The brakes can be upgraded to carbon ceramic brakes which weigh 2 kilograms (4.4 lb) less per wheel, a diameter of 380 mm (15 in) with 34 mm (1.3 in) of contact and eight piston brake callipers.[1][8]
