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.
The 2006 IRL IndyCar Series began on March 26 and concluded on September 10. Sam Hornish Jr. won his third IndyCar Series championship. Hornish also won the 90th Indianapolis 500, passing rookie Marco Andretti on the final lap less than 500 feet (150 m) from the finish line. The title chase was very dramatic between Penske drivers Hornish and Hélio Castroneves battling Ganassi drivers Dan Wheldon and Scott Dixon. The four drivers occupied the first four positions in the final race at Chicagoland Speedway, with Wheldon leading Dixon home for a Ganassi 1–2, but Hornish finishing third, edging out reigning champion Wheldon on a tiebreak. Third would have been enough to catapult fourth-place finisher Castroneves to take the title, but he instead ended up two points behind Hornish and Wheldon. Dixon was also in strong title contention, finishing a mere 15 points adrift of the championship.
Panther Racing was an American open wheel auto racing team. It was one of the oldest continually operating teams in the IndyCar Series.
The 2004 IRL IndyCar Series was dominated by two teams, Andretti Green Racing and Rahal Letterman Racing. While there was great parity in 2003 between Honda and Toyota powered teams, in 2004 Honda began to outshine Toyota bringing their teams Penske Racing and Chip Ganassi Racing down with it, leaving Scott Dixon winless and in 10th place in his attempt to defend his 2003 championship.
The 2000 Indy Racing Northern Light Series was another season that saw a high level of parity, as only one driver, champion Buddy Lazier, won more than a single race. It also saw the beginning of the jump from CART as Al Unser Jr. moved to the series full-time and Chip Ganassi Racing came over to run the Indy 500, which it won with driver Juan Pablo Montoya. It was also the final season for the Riley & Scott chassis, which also saw its first series win in 2000.
The 2001 Indy Racing Northern Light Series saw the addition of five races and loss of one to bring the total to 13. Chip Ganassi Racing returned to the Indy 500 with four cars and were joined on the grid by Penske Racing and Team Kool Green. Sam Hornish Jr. won 3 races on his way to the championship while the less consistent Buddy Lazier won four races on his way to second place in his title defense.
The 2003 IRL IndyCar Series brought some of the biggest changes in its history. The league adopted the name IndyCar Series, after a settlement with CART prohibiting its use had expired. Several former CART teams brought their full operations to the IRL, most notably major squads Chip Ganassi Racing and Andretti Green Racing, as well as former CART engine manufacturers Toyota and Honda, replacing Infiniti who shifted its efforts to the new feeder series Infiniti Pro Series. Many of the IRL's old guard including Robbie Buhl, Greg Ray, and Buddy Lazier had difficulty competing in this new manufacturer-driven landscape. The league also added its first international race this year, taking over the CART date at Twin Ring Motegi.
