History

The Detroit street circuit was created to boost the city’s global image, making the United States the only country to host three Grands Prix in a single season until Italy matched the feat in 2020. The first race in 1982 saw McLaren’s John Watson win from 17th on the grid, then the lowest starting position for a street circuit winner; he broke his own record the next year at Long Beach by winning from 22nd. That same weekend, reigning champion Nelson Piquet failed to qualify his Brabham-BMW after a troubled session, the last time a defending titleholder missed the cut as of this writing.

The circuit earned its place in history when Michele Alboreto won the 1983 race in a Tyrrell 011. That victory marked the final win for the Cosworth DFV V8 engine after 155 Grands Prix, and the last of Tyrrell’s 23 Formula One victories, a run that began with Jackie Stewart in 1971. The track quickly became infamous for its brutal demands. The bumpy surface broke apart under intense heat, punishing cars and drivers more than any other circuit in the 1980s. Races turned into survival contests, with at least half the field retiring each time due to mechanical failures or collisions with concrete walls. Drivers braked hard over 20 times per lap and shifted gears 50 to 60 times—manual gearboxes were still standard—over 62 laps lasting roughly 1 minute and 45 seconds each. Simply finishing was considered a major achievement.
