The 1987 CART PPG Indy Car World Series season was the 9th national championship season of American open wheel racing sanctioned by CART. The season consisted of 16 races, and one non-points exhibition event. Bobby Rahal was the national champion, winning his second-consecutive title. The rookie of the year was Fabrizio Barbazza. The 1987 Indianapolis 500 was sanctioned by USAC, but counted towards the CART points championship. Al Unser won the Indy 500, his record-tying fourth victory at Indy.

Defending series champion and defending Indy 500 winner Bobby Rahal and his Truesports team made a highly publicized switch from the March chassis to the up-and-coming Lola chassis.^[1] Truesports, however, stayed with the proven Cosworth engine. For 1987, the Ilmor Chevrolet Indy V-8 expanded its participation, fielding cars with Penske Racing, Newman/Haas and Patrick. Mario Andretti scored the engine's first Indy car victory in the season opener at Long Beach. Also joining the series full-time was the Judd AV V-8 (badged initially as the Brabham-Honda), and later in the season Porsche made their Indy car debut. Penske resumed their in-house chassis program, but after dismal results with the PC-16, the cars were parked during practice at Indy in favor of the March 86C.

Roberto Guerrero won the second race of the season (Phoenix), starting from last position on the grid due to failing post qualifying inspection. Mario Andretti dominated the Indianapolis 500, leading 171 of the first 177 laps, but dropped out with engine failure with only 23 laps to go. Guerrero took the lead, but stalled during his final pit stop. Al Unser led the final 18 laps to win, one of the biggest upsets in Indy 500 history. Though Guerrero faltered at Indy, he would be a factor through most of the season. After winning at Mid-Ohio in September he was third in points. However he was sidelined with serious head injuries due to a testing crash at the Indianapolis Motor Speedway and was in a coma for seventeen days, missing the remainder of the season.

For the second year in a row, the championship battle came down to Bobby Rahal and Michael Andretti. Rahal took the points lead after back-to-back wins at Portland and the Meadowlands. Andretti won the Michigan 500, and drew within 9 points of Rahal. At Mid-Ohio, Rahal was dominating until he tangled with a backmarker. Andretti had a chance to make up ground in the points, but blew his engine two laps later.

Michael Andretti rebounded, winning in dominating fashion at the inaugural race at Nazareth. But Rahal charged to finish second, and with two races left, held a 25-point lead. In the next-to-last race of the season at Laguna Seca, Andretti dropped out with alternator trouble, and Rahal mathematically clinched the championship. It was Rahal's second-consecutive CART title, and Michael Andretti finished runner-up in points for the second year in a row.
