Alex Palou won the Detroit Grand Prix on Sunday afternoon after starting in the top position and leading the field through the downtown streets.  

Kyle Kirkwood, who won the NTT IndyCar Series race in 2025, finished second and was followed by Graham Rahal. Honda manufactured all three podium finishers' vehicles.

"It was tough, it was very tough. A lot of work on the cockpit, outside with the team on the pit stops and the strategy," Palou said after the race.

Sunday's race marks the fourth win of the season, 23rd career IndyCar win and second Detroit Grand Prix victory (2023) for Palou, who leads the championship points standings.

"It was nip and tuck with Palou and I," Kirkwood said. "It might have been closer than TV showed because I had the tire advantage for restarts, but he had the tire advantage for long stints. With all those restarts, we had a couple good opportunities to pass him."

Rahal's last win came in 2017 at the Detroit Grand Prix when it was on Belle Isle.

"It's just a beautiful American city. It's making a good comeback. Beautiful downtown, vibrant. It's starting to look good. Waterfront is amazing and we love coming here.

Will Power did not finish the race after starting in second. He completed 79 laps before dropping out. Palou dropped out of last year's contest after 72 laps due to contact.

Earlier on Sunday, Enzo Fittipaldi beat out 23 other racers to win the INDY NXT race.

Organizers estimated 150,000 would visit the downtown area throughout the weekend and projected more than $150 million in visitor spending.
