The Koenigsegg CCX is a mid-engined roadster from Swedish car manufacturer Koenigsegg. The CCX has been engineered to comply with the U.S. regulation and market demands and is a newer design that replaced the Koenigsegg CCR.
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 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 main 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 CCX.
Koenigsegg began the CCX project with the aim of entering the world market, though particularly the United States car market. Development engineer Magnus Jaasund said “We wanted to go into the world market, but we couldn’t do it with the old car.” To sell cars to the North American market 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 front bumper of the CCX is designed to be safer in low speed collisions than previous Koenigseggs and the whole body is 3.46 in (88 millimeters) longer to comply with the United States’ rear impact regulations. Additionally the CCX can display United States or European number plates.
The CCX is 1.6 in (41 mm) taller than the CCR and, combined with the carbon fiber reinforced plastic sports seats by Sparco, the CCX allows for 2 in (51 mm) of extra headroom that Autoweek reviewer Mark Vaughn hypothesizes is “to accommodate U.S. NBA stars.” The electronic control unit has also received an upgrade over the CCR meaning that the CCX is without physical fuses and it is lighter than the previous system.
-Acceleration: 0-100 km/h (62 mph) in 3.2 seconds, 0-200km/h (124 mph) in 9.8 seconds
-Top speed: over 395 km/h (245 mph)
-Braking distance: 100–0 km/h (62–0 mph) in 32 m
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.
