Michigan International Speedway (formerly named as the Michigan Speedway from 1997 to 2000) is a 2-mile (3.2 km) D-shaped oval superspeedway in Brooklyn, Michigan. It has hosted various major auto racing series throughout its existence, including NASCAR, CART, and IndyCar races. The facility is currently owned by NASCAR, and is led by track president Joe Fowler. Michigan International Speedway is served by U.S. Route 12 and M-50.
The facility has a capacity of 56,000 as of 2021, down from its peak of 137,243 in 2006. Along with the main track, the track complex also features three road course layouts of varying lengths designed by British racing driver Stirling Moss, which utilizes parts of the oval, parts located within track's infield, and parts located outside of the track's confines.
In the 1960s, Windsor Raceway owner Lawrence LoPatin ordered the construction of Michigan International Speedway to expand his recreational holdings. The facility was completed in 1968, running its first races in October of the same year. Soon after, the track fell into financial trouble after a series of business decisions by LoPatin to expand his auto racing company, American Raceways, sunk the company into major amounts of debt. In 1973, American Raceways sold ownership of the speedway to motorsports businessman Roger Penske, who saved the facility from financial ruin. Under Penske's leadership, the facility was expanded extensively. In 1999, the facility was sold off to the France family-owned International Speedway Corporation (ISC). MIS underwent major downsizing in the 2010s in efforts to modernize the facility, with capacity decreasing to more than half of its peak. Track ownership again changed hands in 2019, when NASCAR merged with ISC.
