The early 2000s saw drivers from the rival CART series begin to cross over to compete at the Indianapolis 500. In the 2000 Indianapolis 500, multiple CART champion team Chip Ganassi Racing brought their drivers Juan Pablo Montoya and Jimmy Vasser to Indianapolis. Montoya qualified second, led 167 laps, and won the race convincingly, becoming the seventh Indy 500 rookie to win the race. The next year, Team Penske made its return to the Indianapolis 500 after a five-year absence and was joined by Ganassi, Walker Racing and Michael Andretti, driving for Team Kool Green in a separate effort headed by Kim Green, known as "Team Motorola". For the second straight year, an Indy rookie won the race as Hélio Castroneves took the checkered flag. Roger Penske then elected to move his entire operation over to the IRL beginning in 2002, taking Castroneves and teammate Gil de Ferran with him. After fielding one car in 2002, Ganassi Racing followed Penske to the IRL full-time for the 2003 season. Michael Andretti, who had left his long-time ride at Newman-Haas Racing because he wanted to run the Indianapolis 500 again (something they were not willing to do), bought a majority interest in CART's Team Green, which returned to Indianapolis in 2002 with Dario Franchitti, Paul Tracy and Michael Andretti, and moved it to the IRL that same year as Andretti Green Racing, and in 2004 former CART champion Bobby Rahal's operation moved to the IRL as Rahal Letterman Racing. Castroneves repeated his Indianapolis 500 win in 2002 despite controversial circumstances involving a late-race caution and a pass made by Tracy, and his teammate de Ferran won in 2003.
