When was the track built?

Detroit’s street-racing story began with a downtown circuit in the 1980s, then moved to Belle Isle Park for most events from 1992 to 2022. In 2023 the Grand Prix returned to the heart of the city on a new 1.645 mile route that threads Jefferson Avenue, Bates Street, Atwater Street, St. Antoine and Franklin/Rivard, pairing fresh pavement with temporary walls, bridges and grandstands.

The hallmark of the modern course is its long Jefferson Avenue run into a deliberately wide Turn 3 hairpin built for overtakes, plus a unique split pit lane that services cars on both sides of pit road.

When was its first race?

The city’s first race downtown was in 1982 (Formula 1). The current downtown layout debuted in 2023 with IndyCar’s Chevrolet Detroit Grand Prix, bringing major-league racing back from Belle Isle to the streets.

What's the circuit like?

  • Jefferson slingshot: Roughly 0.7–0.9 mile of full throttle along Jefferson Avenue funnels hard into the Turn 3 hairpin - the lap’s prime passing zone.
  • Riverfront rhythm: After the hairpin, cars head back up Jefferson then dive down Bates to the Atwater backstretch by the Detroit River before the technical closing sequence.
  • Split pits strategy: The dual-sided pit lane compresses margins on entry and exit and can shuffle order during cautions.
  • Street-surface bumps: The new layout is still bumpy and evolving; grip builds rapidly across the weekend.
  • Benchmark pace: IndyCar race lap record 1:01.941 (2023). 2024 pole was 1:00.548, underlining how quickly the surface has come in.

Lap records and benchmarks (by series)

  • IndyCar (race lap): 1:01.941 - Kyle Kirkwood, 2023 Detroit GP - 1.645 mile downtown layout.
  • IndyCar (2024 highlights): Pole 1:00.5475 - Colton Herta; fastest race lap 1:02.7094 - Colton Herta.
  • IMSA SportsCar Championship: Returned to downtown in 2024 for the Detroit Sports Car Classic on this layout (GTP/GTD PRO sprint format).
  • Historic downtown eras: F1 raced a longer downtown course from 1982–1988 (Ayrton Senna era), with CART on similar streets 1989–1991 before the Belle Isle years.

Why go?

Grandstands in the middle of a major American city, free viewing zones, riverfront scenery and constant restart drama. The Jefferson-to-Turn 3 complex delivers divebombs and switchbacks, and the split pits add tactical suspense you won’t see anywhere else on the IndyCar calendar.

Where's the best place to watch?

  • Turn 3 hairpin: The overtake magnet at the end of the long Jefferson blast - best for starts, restarts and late-braking heroics.
  • Jefferson Avenue frontstretch: Feel the top-speed approach and drafting before the pack compresses into T3.
  • Bates-to-Atwater section: See cars drop toward the river, then accelerate along the waterfront backstretch.
  • Pit lane grandstands: Unique sightlines of the dual-sided stops and the merge - a strategy theater during cautions.

Not just IndyCar: Detroit’s street-racing slate

IMSA SportsCar Championship: Detroit Sports Car Classic on the downtown course since 2024.

Indy NXT & ladder series: Support races showcase future IndyCar stars threading the walls.

Heritage note: Detroit also has the Belle Isle chapter (1992–2001, 2007–2008, 2012–2022) and the original 1980s downtown F1/CART eras - a rich lineage now back where it started: in the streets.
