2006 On September 5, 2006, Foyt was tapped by the 2005 IndyCar Championship team,
Andretti Green Racing, to replace injured regular AGR driver
Dario Franchitti. Foyt drove the No. 27 Dallara Honda in the IRL season's final event at
Chicagoland Speedway and finished 14th. in 2007
2007 In January 2007, Foyt signed with
Vision Racing to return to the IRL for the
2007 season as well as drive with the team in the 2007
24 Hours of Daytona. On August 5, 2007, during the
Firestone Indy 400, Foyt was involved in a seven-car accident in which
Dario Franchitti's vehicle was sent airborne and then came down on Foyt's car. While Foyt was uninjured, Franchitti's car left visible tire marks on Foyt's helmet. Foyt's crew was able to repair the car and get him back on the track where he completed enough laps to finish eighth. The following week at the
Meijer Indy 300, Foyt's crew gave him great pit stops which allowed him to take to lead with ten laps remaining. Even though Foyt was passed a few laps later by
Tony Kanaan and
Scott Dixon, he managed to hold on the rest of the way and drive to a career-best 3rd-place finish, the first Top-5 finish of his career. It was also the best finish in Vision Racing's team history, tying
Tomas Scheckter's third-place finish at the
Milwaukee Mile in 2006.
2008 Foyt returned to be one of Vision Racing's drivers in the 2008 24 Hours of Daytona. He returned to the Vision team for the
2008 IndyCar Series driving the No. 2 car that was formerly driven by
Tomas Scheckter. On March 28, Foyt seemed to have earned a career best start for an
IndyCar Series race at
Homestead-Miami Speedway for the
2008 GAINSCO Auto Insurance Indy 300 with the third best qualifying time. His
Vision Racing teammate,
Ed Carpenter also earned a career best start with the 2nd best qualifying time. He was helped with some drivers ahead of him racing in the
Grand Prix of Long Beach. Foyt had contact with the wall, forcing him to retire from the race early, with a 15th-place finish. The following week at
Kansas Speedway, Foyt and his teammate
Ed Carpenter shared the third row, with Foyt qualifying fifth. It was his best career start and second top-10 start in a row. In the
RoadRunner Turbo Indy 300, Foyt had his chances of a high finish end as his car was caught in the pits when an accident involving
Buddy Rice occurred. Foyt would drive to an eighth-place finish. Foyt's best finish of the season came in the
Iowa Corn Indy 250 in June at the
Iowa Speedway where he finished fifth. Foyt finished the season 19th in the points standings. He returned to the Foyt-Greer Racing team for the
2009 Indianapolis 500, driving the No. 41 vehicle. Foyt finished 16th on the lead lap as his teammate
Vítor Meira was injured in a late-race crash.
Paul Tracy was drafted as the substitute driver for Meira at the next race, but Foyt stepped into the car for his home race at Texas Motor Speedway.
Ryan Hunter-Reay drove the car for the rest of the season and Texas would be Foyt's last race of 2009.
Jaques Lazier was drafted in on short notice to qualify the car but was not fast enough to make the field. ==Post-racing career==
