Streets of Detroit (Detroit Grand Prix), Street Circuit

The Detroit Grand Prix is an IndyCar street race in Detroit, Michigan, that has run on three distinct downtown and island layouts since the 1980s. After early events around the bumpy concrete canyons of the Renaissance Center, the race moved in 1992 to a temporary circuit on Belle Isle, a parkland island in the Detroit River, where Roger Penske promoted the event and the course was built from existing park roadways. The Belle Isle layout was extended in 1998 to roughly 2.35 miles and around 13 turns to improve overtaking, though passing remained difficult, and the event hosted IndyCar and the IMSA WeatherTech Championship through several stints before its final running there in 2022. For 2023 the Grand Prix returned to the heart of the city on a new, condensed street circuit looping around the Renaissance Center, General Motors' headquarters, in downtown Detroit. This current layout measures about 1.645 miles with ten turns and is defined by a long 0.7-mile straight down East Jefferson Avenue. The downtown course was designed to be more accessible to spectators and less disruptive to city traffic than the island venue. Its tight, wall-lined corners and that lengthy straight create heavy braking zones and overtaking chances that suit the modern street-course era. The race remains a fixture of the IndyCar calendar and a showcase event for the city's automotive heritage.
