The Koenigsegg CC8S is a mid-engine sports car produced by the Swedish automobile manufacturer Koenigsegg. It was the company's first production car and the first production car to use the company's trademark dihedral-synchro helix actuation doors. At its introduction, it won several awards, including the Guinness World Record for the Most Powerful Production Engine and design awards from both Red Dot in Germany and Utmärkt Svensk Form in Sweden.The CC8S was developed from the CC prototype. It was the culmination of 8 years of research and development. Despite limited resources, the chassis, suspension, brakes, and several other components were designed in-house by Koenigsegg. The pre-production car was shown at the 2000 Paris Auto Show, the public's reaction to the car was favourable and international contacts were made. The car had many unique functions such as the roof, which could be stored in the car's trunk located in the front similar to how a Chevrolet Corvette stores its roof, vertical opening doors dubbed dihedral-synchro helix actuation doors and a central patented free-flowing exhaust system based on the 'Rocket Cat Principle'. These unique features and design received great praise from the spectators, despite large orders, only 6 cars were produced due to high production costs out of which, 2 were right-hand drive. The CC8S was replaced by the more powerful CCR model in 2004.
