2006 Champ Car World Series

The 2006 Bridgestone Presents the Champ Car World Series Powered by Ford was the 28th season of the Champ Car World Series, the third season of the series under the sanctioning of Open Wheel Racing Series, and encompassed the 95th season of premier American open-wheel car racing alongside the rivaling 2006 IRL IndyCar Series. The season spanned 14 races, beginning in Long Beach, California on April 9 and ending in Mexico City, Mexico on November 12. The Drivers' Championship was won by Sébastien Bourdais and the Nations' Cup by France.

Reigning two-time champion Bourdais won the series championship for the third consecutive time with Newman/Haas Racing, becoming the first driver to win three American open wheel National Championships in a row since Ted Horn in 1948, and the first non-American driver in history to win three titles. For this season the Lola B02/00 chassis (which the series had introduced under its previous CART identity in 2002 continued as the sole chassis for the series for a second consecutive season in what would prove to be the final season of usage for this particular chassis as Champ Car would replace it with a new spec chassis - the Panoz DP01 for 2007. This was also the last CART/Champ Car season prior to the 2008 re-unification of American open-wheel racing to feature a round held on an oval track as the only round on the 2006 Champ Car schedule held on oval at Milwaukee would be dropped for what would prove to be Champ Cars' final season in 2007.
