The streets of Detroit, Michigan hosted Formula One racing, and later CART racing, between the 1982 and 1991 seasons. The course was set up near the Renaissance Center and the Cobo Arena, also including a small part of the M-1 highway, also known as Woodward Avenue.

Created largely in an effort to improve the city's international image, the race meant that the United States would host an unprecedented three Grands Prix in the 1982 season. (The other two US races, Long Beach and Las Vegas, were also added to the schedule for similar purposes.) The inaugural Detroit Grand Prix saw John Watson claim victory after starting in 17th place, the lowest grid position for an eventual race winner on a road course. (Watson would break his own record at Long Beach the next year by winning from 22nd place.)

The narrow track resulted in a large number of cars retiring during the race due to contact with the concrete walls. In its years on the F1 schedule, at least half the field retired in each race. The 1984 race tied an F1 road course record by featuring 20 drivers that failed to finish, eventually setting the record when one finisher was disqualified several months later.

In 1985, Detroit became the sole American venue on the F1 schedule. It also became a track which Ayrton Senna had great success at, winning a pole position in 1985 and then winning three straight races from 1986 to 1988.

The track was only moderately received by the drivers, and it was removed from the schedule in 1989 when Formula One decided to race in Phoenix. Detroit, instead, gained a [Champ Car|[CART]] race, replacing a street circuit in Miami on the schedule.

Three CART races were held on the track. Emerson Fittipaldi won the first and last races and Michael Andretti won the second race; Andretti also won pole position for each Detroit race. The final race featured an unusual lack of attrition as nearly 3/4 of the drivers finished.

The race was not economically viable for the city, so the venue was changed to a temporary course on Belle Isle for the 1992 season. That event lasted until 2001 as a CART event, but is back on the schedule for the 2007 IRL season.
