Sunday, June 15, 1986 – Bill Elliott, winner of 11 races the previous season, scores his first NASCAR Cup Series win of ’86 with a victory in the Miller American 400 at Michigan International Speedway. The victory ended a 14-race skid for the Dawsonville, Ga.-based racer. Elliott made the winning pass with five laps remaining when he overtook Harry Gant. It was the 16th win of his career and fourth on the 2-mile MIS layout.
• Gant, the runner-up, was racing a week after sustaining injuries in the waning laps at Pocono (Pa.) Raceway. Also injured in the Pocono crash was veteran independent driver Buddy Arrington.
• Rick Baldwin, driving in place of Arrington at MIS, was critically injured when his entry slammed into the wall while attempting to qualify. Baldwin remained in a coma for 11 years before passing in 1997.
• Richard Petty was honored in pre-race for making what was said to be his 1,000th career start in the Cup Series. Daughters Lisa, Rebecca and Sharon gave the command to start engines twice – first for their father and then for the remainder of the field. However, Petty actually reached the milestone start three weeks later when the series visited Daytona International Speedway. The mistake was due to Petty being credited with a non-points start in 1959.
