Template:American Championship Car season
The 2005 IRL IndyCar Series 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 IndyCar Series 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. Dan Wheldon also became the first IndyCar driver to win the Indianapolis 500 and IndyCar Series overall driver's title, respectively, in the same season since Jacques Villeneuve in the 1995 PPG IndyCar World Series season and also the first in the Indy Racing League era.
The season was the first to introduce road courses and street circuits when the series held races at the Streets of St. Petersburg, Infineon Raceway and Watkins Glen International, where the series was previously known to have held events exclusively on oval tracks. Wheldon also became the series' first road/street course winner when he won in St. Petersburg.
The season was also the last for Chevrolet in the series, who confirmed in August that they would not return to the IRL (Chevrolet returned in 2012). 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 IRL's only supplier. The IRL announced that they extended their chassis supply contract with Panoz and Dallara through 2006.
Rule changes for 2005
- A mandated switch to the single-point re-fueling systems used by some teams in 2004. The IRL only approved one type of fueling probe and buckeye, and these only work as a single-point system. In the approved system, two hoses coming from the storage tank combined at the fueling mechanism, handled by the fueler. The crew member previously responsible for the operation of the vent and jack was now free to operate only the jack.
- Cars raced on all ovals in the same configuration introduced at the 88th Indianapolis 500 in May 2004 with minimal aerodynamic changes. The changes were limited to specific areas of the underwing and sidepods. The IRL required teams to use the same engine cover as the previous year without modifications.
- Teams were allowed to change engines prior to qualifying without penalty at the following events, which were scheduled to be three-day events: Homestead, St. Petersburg, Motegi, Texas, Milwaukee, Infineon, Watkins Glen, and California.
- The amount of methanol that teams were allowed to have in their trackside tanks was changed. Teams were allowed to carry 85 gallons for 187.5-mile races, 90 gallons for 200-mile events, 100 gallons for 225-mile events, 125 gallons for 260-mile races, 135 gallons for 300-mile events, 175 gallons for 400-mile events and 225 gallons for 500-mile events.
- The mandatory minimum weight of cars was 1,600 pounds, 75 pounds heavier than the oval minimum weight. The additional weight was attributed to the brake system, which consisted of an aluminum brake caliper, steel rotor and pad as specified by the IRL, as well as the limited slip differential in the gearbox.
