The NTT Indycar Series runs its seventh round of the 2023 season with this weekend’s Chevrolet Detroit Grand Prix presented by Lear. The new, 1.7-mile, nine-turn street circuit runs through parts of downtown and along Jefferson Avenue and back around to Atwater Street along the Detroit River, with a new split pit lane also part of the features. There will be two practice sessions and a qualifying bout ahead of Sunday’s 100-lap (164.5 miles) race set for 3 p.m. ET (live, NBC, Peacock, INDYCAR Radio Network).
