Michigan International Speedway opened in 1969 under the management of promoter Roger Penske, who acquired the facility in 1973. The track's two-mile oval with wide, sweeping corners enabled drafting and side-by-side racing across large portions of the layout, making Michigan a venue where multi-car battles for position could be sustained for extended periods. The summer and fall races at Michigan developed reputations for producing large numbers of lead changes and unpredictable outcomes.
For most of its history from 1971 through 2020, Michigan hosted two Cup events per year. Beginning in 2021, only one race was scheduled annually after Dover Motorsports moved one of its Michigan dates to Nashville Superspeedway.
In 1970, restrictor plates made their racing debut at Michigan in the Yankee 400, with Charlie Glotzbach driving a Dodge Daytona to victory. The 1974 summer race saw the lead change 45 times among eight drivers as Cale Yarborough and David Pearson fought for position before an ill-matched tire set ended Yarborough's challenge.
The 1975 race produced a classic finish between Pearson and Richard Petty. After a late caution set up a five-lap sprint, the two exchanged the lead on every circuit down to the line, with Petty winning by a nose. The 1978 race was Pearson's final win with the Wood Brothers, settled on a one-lap shootout over Darrell Waltrip.
The 1981 summer race stands out as arguably the most competitive Michigan event in the race's history — 65 lead changes among 14 drivers, with Petty charging from fifth to the lead in the final five laps and holding off six challengers.
In 1987, Tim Richmond's final career race took place at Michigan. Before qualifying, Richmond had to be roused from his motorhome and asked aloud where the race was being held. After an anxiety attack during the event, he deliberately over-revved his engine to end his participation. It was the last time Richmond competed in NASCAR.
Ernie Irvan won the 1997 summer race at Michigan — his lone win of the season, and the final win for car owner Robert Yates — at the track where he had suffered near-fatal injuries in 1994. The symbolism of his return to victory at the site of his accident was widely noted.
Dale Earnhardt Jr. won the 2008 summer race on Father's Day, snapping a 76-race winless streak — equal to his father Dale Earnhardt's total career win count. The win marked Earnhardt Jr.'s first points race victory with Hendrick Motorsports. He returned to win the same race again in 2012, on Father's Day, snapping a 143-race drought, leading 95 of 200 laps.
The 2016 summer race produced Kyle Larson's first career Cup Series win, with Chase Elliott finishing second in what was also Elliott's runner-up result at the earlier June race that season.
Michigan International Speedway built its reputation as a fast, passing-friendly oval where driver talent and car setup could overcome deficits across the course of 200 laps. The Pure Michigan tourism campaign's association with the race gave the event a regional branding that reflected the track's deep ties to the Michigan automotive industry. David Pearson's record nine Michigan wins — achieved across both spring and fall races — stands as the all-time benchmark, while Bill Elliott's dominance in the mid-1980s (winning the Michigan 400 in three consecutive years from 1984 to 1986) represents one of the more concentrated stretches of single-track mastery in the modern era.
