Michigan International Speedway

Michigan International Speedway is a two-mile D-shaped asphalt oval in Brooklyn, Michigan, known for producing some of the fastest average speeds in NASCAR racing. Its wide racing surface and sweeping 18-degree banked turns allow for multiple grooves and high side-by-side competition. The track hosts NASCAR Cup Series and NASCAR O'Reilly Auto Parts Series events and has been a premier venue on the NASCAR schedule since opening in 1968.

Lawrence LoPatin, the treasurer of Windsor Raceway, built Michigan International Speedway in the Irish Hills near Brooklyn, Michigan, and it opened in October 1968. His company, American Raceways, soon sank into debt, and in 1973 Roger Penske bought the track and saved it. Penske expanded MIS for more than 25 years before selling it to the International Speedway Corporation in 1999. The wide, two-mile D-shaped oval is one of NASCAR's fastest tracks. Seating was cut to less than half its peak in the 2010s, and NASCAR became the owner when it merged with ISC in 2019.
