Detroit Grand Prix Circuit – Downtown & Belle Isle IndyCar Guide
Originally published May 2016. Last updated September 2026: expanded Tier B circuit guide, facts table, table of contents, 2023 downtown return context, internal links, FAQ schema, and editorial refresh while preserving legacy narrative and images.
The Detroit Grand Prix is an IndyCar street race rooted in downtown Detroit — back on city streets since 2023 after three decades that were mostly spent on the Belle Isle park road course in the Detroit River. Formula One ran seven United States rounds on downtown Detroit streets from 1982 to 1988; CART followed before the island layout opened in 1992 and became the home of Chevrolet’s title-sponsored double-header era.
The event matters because it ties America’s automotive capital to open-wheel history: narrow Belle Isle laps, record crowds above 110,000, and now a 1.7-mile downtown loop along the Riverwalk with split pits and free public viewing on much of the course. Compare other US street races at Long Beach Street Circuit, St. Petersburg Street Circuit, and Indianapolis Motor Speedway.

F1 Grand Prix track in downtown Detroit
The year was 1982 and one of three Formula One World Championship Grands Prix in the United States was the Detroit Grand Prix. The race was held at a temporary street circuit set up near the Renaissance Center and Cobo Arena. Seven Formula One Grands Prix took place in Detroit between 1982 and 1988. After Formula One left Detroit, the CART Indy Car World Series came to town in 1989.

The Belle Isle circuit opened in 1992
The circuit in the city centre was used until 1991, when a new temporary street circuit was constructed on Belle Isle in the Detroit River. The island hosted ten CART events from 1992 to 2001. The racers then left Detroit’s race track for the next five seasons.
Economic crisis caused the cancellation
In 2007, racing at Belle Isle resumed as the track joined the IndyCar Series and American Le Mans Series. In December 2008, the scheduled race for the 2009 season was canceled. The main reason was the global economic crisis, which especially impacted the automotive industry and Detroit as the United States automotive capital, because the biggest manufacturers (Chevrolet, Ford, Chrysler) have headquarters in the Detroit area.

Island return to racing in 2012
In 2012, race car drivers returned to the Belle Isle street circuit, with three racing series included – IndyCar Series, Tudor United SportsCar Championship and Pirelli World Challenge. Since then, the Detroit Grand Prix was held without interruptions. IndyCar Series had a so-called double-header at Detroit from 2013, with two separate races in one weekend.

Two layouts of the Belle Isle road course
Since opening, the Belle Isle road course had two main lengths. The original was the 2.1-mile layout around the park and it was used until 1997. In 1998, the circuit gained an extension of the main straight and the new layout was 2.36 miles long, used until 2001. In 2007 and 2008, when racing returned to the island, the short layout was used, and then again in 2012. From 2013, the longer layout was again in use through the final Belle Isle race in 2022.

Fourteen turns on a narrow, twisty island course
The Belle Isle circuit featured fourteen turns in the clockwise direction. As with most street circuits, the Belle Isle track was narrow and twisty, with few passing opportunities. Compared with the old Grand Prix track in downtown Detroit, the island course offered better spectator facilities.
The circuit on Belle Isle is connected to Detroit by the MacArthur Bridge. On race weekends, there was no parking on the island and fans were required to use shuttle bus facilities. Record attendance on a racing weekend was over 110,000 spectators in 2014.
Besides IndyCar, Belle Isle hosted prototype and GT racing
First winner at Belle Isle was Bobby Rahal
Since 1992, spectators saw nineteen IndyCar Grand Prix races at the Belle Isle circuit. The first winner of the IndyCar Detroit Grand Prix was Bobby Rahal. The next on the winners’ list were Danny Sullivan, Paul Tracy, Robby Gordon, Michael Andretti, Greg Moore, Alex Zanardi, Dario Franchitti and Helio Castroneves. In 2001, Castroneves became the first double Grand Prix winner at the Belle Isle racing track.
Scott Dixon set the Belle Isle lap record
In 2007 and 2008, Tony Kanaan and the late Justin Wilson were the winners. Between 2012 and 2015, Scott Dixon, Mike Conway, Simon Pagenaud, Will Power, Carlos Munoz and Sebastien Bourdais joined the list of Grand Prix winners. Helio Castroneves won again in 2014 to become a triple winner at Belle Isle. The fastest IndyCar lap on the island layout belongs to Scott Dixon — 1:10.3162 in 2012.
In 2014, Helio Castroneves scored his third win at Belle Isle
Castroneves and Kanaan acquired three wins
Since 2007, sports car races were part of the Detroit Grand Prix at Belle Isle. The first winners were Romain Dumas and Timo Bernhard in Penske Racing’s Porsche RS Spyder Evo. In 2008, Franck Montagny and James Rossiter took the honours in Andretti’s Acura ARX-01B. Between 2012 and 2015, both Action Express Racing and Wayne Taylor Racing scored two victories at Belle Isle. The only driver who won twice was Jordan Taylor.
Other series also raced at Belle Isle, including Indy Lights, Trans-Am and Pirelli World Challenge. Tony Kanaan scored two wins as an Indy Lights competitor, matching Helio Castroneves’ three IndyCar victories on the island.
Return to downtown streets (2023–)
Organisers announced in 2021 that the Chevrolet Detroit Grand Prix would leave Belle Isle after the 2022 event and return to downtown Detroit from 2023, reviving the spirit of the 1980s and early-1990s city-centre races while improving public access along the Riverwalk.
The current course is about 1.7 miles (2.7 km) with nine turns, using Jefferson Avenue, Bates Street, Atwater Street, and roads around Hart Plaza and the Renaissance Center. IndyCar runs a single 100-lap race on the shortened layout, with a distinctive split pit lane that merges back onto the circuit. A long Jefferson straight — roughly seven-tenths of a mile — was designed to create more passing than the tight Belle Isle esses.
