The 1991 CART PPG Indy Car World Series season was the 13th national championship season of American open wheel racing sanctioned by CART. The season consisted of 17 races, and one non-points exhibition event. Michael Andretti was the national champion, and the rookie of the year was his younger brother Jeff Andretti.

The 1991 Indianapolis 500 was sanctioned by USAC, but counted towards the CART points championship. Rick Mears won the Indy 500, his record-tying fourth victory in the event.
Michael Andretti won a total of eight races, eight pole positions, and led more than half of the laps during the season, but the championship battle still went down to the final race of the season. Bobby Rahal won only one race, but had 11 podium finishes and 13 top tens. Rahal's consistent season put him in position to challenge Andretti for the title in the season finale at Laguna Seca. Andretti got off to a slow start to the season, dropping out of the first two races, and finished a heartbreaking second at Indianapolis. But after Indy, he shot to the top of the standings. He won four of the last five races of the season, and needed to finish 6th or better at Laguna Seca to clinch the title. When Bobby Rahal dropped out at Laguna Seca with overheating problems, Andretti cruised to the title.

Preseason
On August 6, 1990, Bettenhausen Motorsports confirmed its plans for a full 1991 campaign with driver/owner Tony Bettenhausen Jr. in the No. 16 car.
On September 18, 1990, Penske Racing announced it would downsize its program back to a two-car team for 1991 by not exercising their option on Danny Sullivan, as sponsorship from Pennzoil had switched to Hall/VDS Racing.
On October 8, 1990, Hall/VDS Racing announced it had signed John Andretti as their lone driver in a two-year deal. Andretti switched to the No. 4 car from Porsche North America after the German manufacturer stopped its Indy Car program.September 12, 1991 Article clipped from The Plain Dealer https://www.newspapers.com/article/the-plain-dealer/169765797/ April 7, 2025 The Plain Dealer 86
On October 12, 1990, King Motorsports announced the signing of Jim Crawford for its partial schedule in the No. 26 car, including the Indianapolis 500.
On October 30, 1990, Patrick Racing announced that Danny Sullivan had signed to drive the No. 20 car in 1991, replacing Roberto Guerrero.
On November 3, 1990, Bayside Racing signed Jeff Andretti as its new driver for the No. 86 car, replacing Dominic Dobson.
On November 20, 1990, A. J. Foyt announced his plans to retire from competition after the 1991 season, during his recovery from the leg and feet injuries sustained on September 23, 1990, in a crash at Road America. Foyt, who had dismissed the notion of retirement in early press conferences after his crash, clarified it had been his plan all along.October 10, 1990 Article clipped from The Indianapolis Star https://www.newspapers.com/article/the-indianapolis-star/48392193/ March 26, 2025 The Indianapolis Star 33 However, he remained non-committal for the rest of 1991 regarding his future plans.
On December 14, 1990, Scott Pruett received the mandatory medical approval to return to the No. 11 Truesports car for 1991. Pruett had been sidelined for the whole 1990 season due to severe leg injuries in a pre-season crash, with Raul Boesel as the fill-in driver throughout the year.
On January 8, 1991, Menard Racing announced that Kevin Cogan and Gary Bettenhausen would drive its two Buick-powered Lola T91/00 cars at the Indianapolis 500, entered as No. 9 and No. 51. Bettenhausen had driven a year-old Lola with Menard in the previous edition.
On February 8, 1991, the Indianapolis News reported that Euromotorsport had signed John Jones to drive the No. 50 car, taking the place of Mike Groff. However, the necessary funding for the seat did not materialize, and Jones was replaced for the Surfers Paradise round by the returning Groff, who would remain in the car as the full-time driver.

On April 19, 1991, it was reported that Todd Walther Racing had been disbanded, after just two races in their second CART season.
From June onwards, Hemelgarn Racing partnered with Dale Coyne Racing to field a car in a variety of races for Buddy Lazier, with the same strategy employed by Nu-Tech to share franchising earnings. The partnership was known as Hemelgarn Coyne Racing.
On June 21, 1991, Bob Tezak warned that Vince Granatelli Racing risked shutting down for the season due to a lack of sponsorship, despite Arie Luyendyk running third in the standings at the time.June 22, 1991 Portland race may be the last for Luyendyk this season https://www.newspapers.com/article/the-oregonian-portland-race-may-be-the-l/169028307/ March 28, 2025 The Oregonian 57 The next week, Granatelli severed ties with Tezak, who was blamed by Luyendyk of mismanagement and failure to pay his salary, and the team scrambled to find funding to compete on a race-by-race basis.June 27, 1991 Article clipped from USA Today https://www.newspapers.com/article/usa-today/169028561/ March 28, 2025 USA Today 13June 28, 1991 Grantelli, Luyendyk to continue https://www.newspapers.com/article/the-indianapolis-star-grantelli-luyendy/169028615/ March 28, 2025 The Indianapolis Star 30June 25, 1991 Article clipped from The Indianapolis News https://www.newspapers.com/article/the-indianapolis-news/169028640/ March 28, 2025 The Indianapolis News 10
After the June 23, 1991, race at Portland, Genoa Racing discontinued its short-lived Indy Car program. The team had suffered from economic woes due to the crash of Guido Daccò at Phoenix, the loss of major sponsorship during the Month of May and the subsequent withdrawal from the Indianapolis 500, also skipping the following event at Milwaukee.
In August 1991, Euromotorsport skipped the Michigan 500 entirely, due to an alleged engine testing session. The team had both their primary and spare cars damaged to various degrees during the previous Toronto event.
On August 27, 1991, A. J. Foyt Enterprises announced they would skip the race at Vancouver due to a lack of a spare car. One week earlier, the team had not been allowed to race at Denver after Mike Groff wrote off his primary car in a practice crash, as the spare car had not been entered.
