2005 IndyCar Series season

IRL Seasons
Current = 2005
Previous = 2004
Next = 2006 The 2005 Indy Racing League IndyCar Series season began on Sunday, March 6 and ended on Sunday, October 16. The season, which consisted of 17 races, was the 10th season of the IRL since it split from CART in 1995.

Dan Wheldon was the dominant driver in the series in 2005, winning six races, including the 89th running of the Indianapolis 500, setting the record for most victories in an IRL season. However, the big story of the season was that of Rahal Letterman Racing's Danica Patrick, the fourth woman to compete in the Indy 500 and the first to lead a lap. She would eventually wind up in fourth. Danica's presence was a boost to the IRL's television ratings. The Indy 500's ratings were up 40% from the year before and subsequent races also saw a boost in ratings.

The season was also the last for Chevrolet in the series, who confirmed in August that they would not return to the IRL. At the start of the season, only Panther Racing's Tomas Scheckter and Tomáš Enge raced Chevrolet powered cars (although A.J. Foyt IV also started racing for Chevy beginning with the AMBER Alert Portal Indy 300 at Kentucky). The manufacturer situation within the IRL was the hot issue during the second half of the season and continued into the off-season. Toyota announced that they would leave the series shortly after the 2005 season ended, leaving Honda as the only remaining manufacturer in the IRL. Honda extended their engine supply contract through 2009 despite expressly saying that they did not wish to be the IRL's only supplier.
