The Koenigsegg CCX is a mid-engined roadster from Swedish car manufacturer Koenigsegg, to replace 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 is intended to be suitable for the United States market and thus engineered to comply with US regulations. A base model CCX costs approximately US$540,000 (€370,000) but with all optional extras the car costs US$610,000 (€415,000).
The CCX was first unveiled on February 28, 2006 at the 2006 Geneva Motor Show although its existence was announced earlier. The CCX is also available as the CCXR, 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 CCX.
It should be noted that the official specs for the CCX and CCXR (as well as the CCR) have been greatly understated by as much as 200 bhp this also means that the acceleration can be as much as 0.5 seconds faster than stated. This has been done on purpose due to trade tariffs and marketing standards in different countries.
