Champ Car World Series is an international open-wheel championship based largely in North America. This series was created after split between CART and the IRL.
Most common, Champ Cars are either Fords, Chevrolets, or Honda but the all use a turbocharged 2.56 liter V8 engine with 800 hp. The cars have a 7 speed paddle shifting transmission and they weigh about 1575lbs without the driver. A Champ Car is a single-seat (commonly called open-wheel in the US) racing car. For much of their history Champ Cars have been similar to Formula One cars. Over the years, Champ Cars race schedule included high speed oval tracks. The increased stress and speed of these tracks mean that the cars tended to be heavier and have longer wheelbases than F1 cars (increasing stability but decreasing agility).
Some of the top teams in the Champ Car series are Conquest Racing, Pacific Coast Motors and Haas Racing. Some of the notable current drivers in the series are Sébastien Bourdais, Dan Clarke, and Mario Dominguez. Shinji Nakano is a Japanese driver that once raced in the Champ Series from 2000 to 2002. Born April 1, 1971, he started racing when he was thirteen and moved his way around different race series including Formula 1 and Champ Cars. He has yet to win a race in any series. (Mike)
