Koenigsegg CCX

Koenigsegg CCX

The Koenigsegg CCX is a mid-engined sports car built by Koenigsegg Automotive AB. The project began with the aim of making a global car, designed and engineered to comply with global safety and environment regulations, particularly to enter the United States car market To sell cars in the US many alterations were made to the design of the CCR; the previously used Ford Modular engine was replaced by a Koenigsegg engine designed to run on 91 octane fuel, readily available in the United States, and to meet the Californian emission standards.The name CCX is an abbreviation for Competition Coupé X, the X commemorating the 10th anniversary (X being the Roman numeral for ten) of the completion and test drive of the first CC vehicle in 1996.


The new engine is of all aluminum construction, made out of 356 aluminum with a T7 heat treat to further enhance block integrity and cylinder bore chill during casting. Specifically created and cast for Koenigsegg by Grainger & Worrall, a casting specialist with F1 experience in drivetrain components, the engine is built, assembled and tested at their Ängelholm production plant. The engine is lubricated with a dry sump system with a separate oil pump and the pistons are cooled by means of an internal cooler that sprays oil onto them in order to run high cylinder pressure with 91 octane fuel  making it capable of 14 mpg (17 l/100 km) in combined cycle and 18 mpg (13 l/100 km) in highway travel. Available transmissions are a Cima 6-speed manual and a 6-speed automated manual. Power is fed to the wheels through a torque-sensitive limited slip differential.


The chassis is made from carbon fiber reinforced with kevlar and aluminium honeycomb like previous models and while the body keeps the targa top body style and the "dihedral synchro-helix" actuation doors it is completely reworked, there is a new front bumper design, enhanced brake cooling, fog lamps, US position lights, a new fresh air intake on the bonnet that acts as ram air booster, air intakes behind the front wheels to enhance airflow and a glass window over the engine.
The CCX has frontal area of 2,894 sq in (1.867 m2) and a drag coefficient of 0.30. It also has a flat underside with venturi tunnels at the rear and an optional rear spoiler to improve aerodynamics. At 200 km/h (120 mph) there is 60 kg of downforce over the front axle and 65 kg over the rear. The car is 88 mm (3 in) longer to comply with the US rear impact regulations and to free space around the rear muffler. On the interior side, there is 51 mm (2 in) of extra headroom as well as specifically designed Sparco carbon fiber seats


The CCXR is a more "environmentally friendly" version of the CCX, powered by the same engine, but converted to use E85 and E100 ethanol fuel, as well as standard 98 octane petrol. The CCXR required modified fuel injectors, upgraded fuel lines and piston rings, and a higher boost setting on the superchargers.When run on ethanol, the power increases to 1,018 PS (749 kW; 1,004 hp) at 7000 rpm and 1,060 N·m (782 lb·ft) of torque at 5600 rpm. This is a direct result of the cooling properties of ethanol in the engine's combustion chambers along with the added boost, made possible by ethanol's higher octane rating when compared to gasoline. Due to the lower specific energy content of ethanol, the CCXR burns slightly more fuel than the CCX with a combined fuel consumption of 22 L/100 km (13 mpg-imp; 11 mpg-US) under the EU cycle.
In March 2009 the CCXR was chosen by Forbes as one of the ten most beautiful cars in history.


At the 2008 Geneva Motor Show Koenigsegg presented two special edition models, the CCX Edition and the CCXR Edition, both fitted with a remapped, 4.8 L twin-supercharged V8 engine and limited to 2 and 4 units respectively. The modifications to the engine increase the power of the CCX Edition to 888 PS (653 kW; 876 hp) and 940 N·m (693 lb·ft) of torque while the CCXR Edition ratings remained largely unchanged over the CCXR. Later Koenigsegg also built 2 CCXR Special Edition cars with compared to the old CCXR Edition had updated aerodynamics and a F1 Paddleshift system.
The Edition models are more track oriented compared to the standard models, being equipped with stiffer springs and anti-roll bars, reset dampers and a lowered chassis and a fully visible carbon body, unique 11 spoke wheels and a large adjustable rear wing, larger front splitter and side strakes capable of producing 350 kg (772 lb) of downforce at 250 km/h (155 mph). The interior is also reworked and features: color matched leather carpets, Koenigsegg Edition side step plates, Edition chronograph instrument cluster, a new Edition only layout for the center console control panels, and features a special version of the Koenigsegg Chronocluster including a redesigned center console. All other extra equipment for the Koenigsegg Edition CCXR and CCX comes as standard: carbon wheels, special interior trim and color, rearview camera, Satnav or Bluetooth, amplifiers, complete Inconell exhaust system.

CCXR Trevita

The CCXR Trevita is a limited edition of the Koenigsegg CCXR Edition featuring a diamond weave carbon fibre finish. Trevita is an abbreviation in Swedish and translates into - three whites. Up until the development of the CCXR Trevita, it has only been possible to utilize the classic black carbon fibres.The Koenigsegg Proprietary Diamond Weave, fully developed by Koenigsegg, is a new and unique method to manufacture the carbon fibre material for the CCXR Trevita. By utilising this new and unique method, Koenigsegg has managed to coat fibres with a diamond finish. The process was fully developed at Koenigsegg headquarters in Ängelholm Sweden, where the fibre treatment is conducted carefully in small quantities, prior to further processing the prepreg material. The car is one of the world's most expensive streetlegal supercar, it has a total price of US $4,850,000 (€3,400,000 or 35,000,000 Swedish krona).Only three CCXR Trevitas were produced, making one of the rarest vehicle manufactured by Koenigsegg. All three cars featured the Koenigsegg Shimmering Diamond Weave bodywork, double carbon rear wing, inconel exhaust system, carbon ceramic brakes with ABS, airbags, paddle-shift, chrono instrument cluster, infotainment system, tire monitoring system and a hydraulic lifting system
