The 2005 Bridgestone Presents the Champ Car World Series Powered by Ford season was the 27th overall and the second season of the Champ Car World Series era of American open-wheel racing. It began on April 10, 2005 in Long Beach, California and ended on November 6 in Mexico City, Mexico after 13 races. The Bridgestone Presents the Champ Car World Series Powered by Ford Drivers' Champion was Sébastien Bourdais, his second consecutive championship. The Rookie of the Year was Timo Glock. The season saw the Lola B02/00 (which debuted in 2002) become the sole chassis for the series.
The 2.65 liter turboV8Ford-Cosworth XFE engine continued to be the exclusive power plant for the series. Bridgestone continued on as the exclusive series tire supplier as well. The two companies continued the marketing agreement that branded the series Bridgestone Presents the Champ Car World Series Powered by Ford. All teams ran the Lola B02/00 chassis after the 2002 bankruptcy of Reynard Motorsport prevented further development of their Reynard 02I, causing it to become uncompetitive against the Lola.
Domínguez's former team, which renamed itself HVM Racing from Herdez Competition after the salsa company ended its title sponsorship, began the season with 2003 Formula 3000 championBjörn Wirdheim and Toyota Atlantic driver Ronnie Bremer.[7]
Björn Wirdheim did not complete the season with HVM Racing. Fabrizio del Monte joined the team for the Surfers Paradise round[14] and was slated to drive at the finale in Mexico City but suffered a concussion in a crash in practice at the Autódromo Hermanos Rodríguez and was not medically cleared to race.[15]
Cedric the Entertainer entered into a partnership with HVM Racing in October 2005. The race team was rebranded CTE Racing-HVM from that point forward.[20]
CTE Racing-HVM gave Mexican driver Homero Richards a one-off drive at the race in Mexico City.
The initial 2005 schedule announced by Champ Car included 14 races,[21] but only 13 races actually took place during the season. The 14th race was scheduled to take place at a newly constructed permanent road circuit in the city of Ansan, South Korea on October 16, the week before the race at Surfers Paradise. The race was canceled in September when it was determined that the circuit was not ready to host the race.[22] It was the second year in a row that a race in Korea was canceled, as a street circuit race in the capital of Seoul was removed from the 2004 schedule. A date at the Ansan circuit was placed on Champ Car's initial 2006 schedule but that race would never take place either.
