2007 Koenigsegg CCX
Although the looks is the same, the CCX is essentially a new car as it has been redesigned to comply to all U.S. regulations. CCX stands for Competition Coupe X and commemorates the 10 year anniversary of the first CC prototype. The CCX features a new front bumper designed to perform better in crash tests as well as provide enhanced brake cooling. New side skirts have been added to increase downforce by increasing underbody area.
The Engine in the CCX retains the incredible performance and power of the CCR engine, while running on US 91 octane fuel and complying with California emission regulations. In order to reach this challenging goal, extensive rework had to be done to emission related items, such as new cylinder heads with larger valve area and more optimally flowing cylinder head ports. Dual smaller injectors per cylinder were integrated, as well as new camshafts, a new carbonfiber individual runner intake plenum, a new engine management system, updated fuel and EVAP system. New exhaust system where the catalytic converters are moved closer to the engine for earlier light-off time. A returnless fuel system has also been implemented with pumps integrated into the new fuel tank. All in all, a heavy rework in order to retain the unique performance of the CCR engine and at the same time comply with the strictest emission regulations in the world.
As expected, the CCX keeps the same great performance as the CCR including a 0-62MPH time of 3.2 seconds, 1/4 mile time of 9.9 seconds @146MPH and top speed over 245MPH.
