Source-derived summary

The 1987 Michigan 500, the seventh running of the event, was held at the Michigan International Speedway in Brooklyn, Michigan, on Sunday, August 2, 1987. Branded as the 1987 Marlboro 500 for sponsorship reasons, the race was won by Michael Andretti, his first Michigan 500 victory. The event was race number 9 of 15 in the 1987 CART PPG Indy Car World Series.

Background

In November 1986, the Michigan 500 was renamed the Marlboro 500. It was the first title sponsorship for the race since Norton withdrew their sponsorship following the 1982 race.

Al Unser won the 1987 Indianapolis 500. Unser got the job at Team Penske after Danny Ongais suffered a concussion during practice. Penske entered cars for both Unser and Ongais in the Michigan 500.

Entering the Michigan 500, Tom Sneva was fired by his Mike Curb-owned team after his wife complained that the team was behind in Sneva's paychecks. On Monday July 27, Sneva was informed by Curb's lawyer that he was fired from the team.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
