Detroit street circuit

The street circuit 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.

[1] Created largely in an effort to improve the city's international image, the race meant that the United States would host three Grands Prix in the 1982 season (the other two US races, Long Beach and Las Vegas, had been added to the schedule for similar purposes), the only nation in F1 history to do so until the 2020 season, when Italy also hosted three Grands Prix: Monza, Mugello, and Imola.

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 street circuit.

The Detroit street circuit's place in Formula One history was assured when Michele Alboreto won the 1983 race driving a Tyrrell 011.

By 1985, Detroit was the sole American venue on the F1 calendar—Las Vegas had been dropped after 1982, Long Beach switched to Champ Car for 1984, and a new event in Dallas only lasted one year after the heat and deteriorating track conditions almost saw it cancelled on the morning of the race.

[2] The 1988 race, similar to the failed Dallas event, was extremely hot, and the circuit broke up very badly due to the intense heat and humidity.

The United States Grand Prix moved to another street circuit in Phoenix, Arizona, while the Detroit event became a CART race.

The Motor City 100 was often regarded as one of the most important events of the Trans-Am schedule due to the increased television and sponsor exposure, made possible by the international broadcast of the Grand Prix.

This often made the Grands Prix a more difficult prospect due to drivers having to go offline on to the 'dirty' part of the road to avoid problem areas on the track surface.
