DETROIT (Sunday, May 31, 2026) – Four-time NTT INDYCAR SERIES champion Alex Palou prevailed in a full- contact race filled with various tire strategies, winning the Chevrolet Detroit Grand Prix presented by Lear on Sunday for his fourth victory in eight races this season.
Pole sitter Palou drove his No. 10 HRC Chip Ganassi Racing Honda to a 3.0584- second victory over the No. 27 Sam’s Club Honda of Andretti Global’s Kyle Kirkwood.
It was the 23rd victory of Palou’s career in 106 starts, a remarkable strike rate of 21.7 percent, and he has won 12 of the last 25 races (48 percent win rate) dating to the start of the 2025 season.
“It feels like the first time, honestly” Palou said. “It was a tough one, a very tough one. But the team did an incredible job once again with the strategy. The pit stops were incredible. Incredible run, incredible start of the year, but it was tough.”
The victory extended Palou’s championship lead to 62 points over Kirkwood, more than a race’s worth of margin. The Spaniard is aiming for an INDYCAR SERIES record- tying fourth straight title.
Arrow McLaren teammates Pato O’Ward and Christian Lundgaard finished fourth and fifth in the No. 5 and No. 7 Chevrolet-powered cars, respectively, at General Motors’ home event.
Palou led 71 of the 100 laps, but this wasn’t a stroll down Easy Street. He took the lead for good on Lap 69 when Kirkwood pitted from the lead for the last time and stayed out
front on restarts on Laps 72, 76, 83 and 93 after full-course yellows bunched the field.
The move to the front was paved a few laps earlier when strategist Barry Wanser and Palou decided to make their final pit stop at the end of Lap 63, switching from the faster but less durable Firestone Firehawk alternate tire to the primary tire. Wanser saw a variety of jousts for position unfolding on the tight, nine- turn, 1.645-mile street circuit and wisely didn’t want Palou to get caught on track under caution and lose track position.
“We took a little bit of a gamble on tires there, being the only guy on reds (alternates) at the end,” Kirkwood said. “It nearly paid off. It was so, so close. There were two untimely yellows.
“We almost covered Palou when we were on primes, which would have been phenomenal, and then we had that other yellow where I had him lined up. I was ready to make a dive on him, and, of course, (the yellow) comes out after I burned 10 seconds of overtake. From there, we just didn’t really have another shot at it. I think I just used up my tires too much to make that one pass.”
Palou kept the lead on the restart on Lap 83, but Kirkwood continued to push and forced Palou into
a flat-spotting tire lockup on Lap 88. But Palou gathered himself and his car and started to pull away, building a lead of 1.8929 seconds by Lap 91.
But there was one more restart for Palou to manage after Rossi clipped the rear of the No. 18 BMax Honda driven by Romain Grosjean of Dale Coyne Racing and sent Grosjean into the outside wall approaching Turn 3 on Lap 91. That triggered the last of six full-course yellows, but Palou pulled away from Kirkwood and the field on the Lap 93 restart and was never threatened despite the 173 on-track passes today, a high for a street circuit this season.
“Being able to be up front was key,” Palou said. “On the first stint, I started struggling and kind of put myself in a bad spot and lost two positions with Lundgaard and (Scott) McLaughlin. I lost us positions there, but the team made a great call to be safe with the yellow. It kind of worked out for us.”
The next NTT INDYCAR SERIES race is the Bommarito Automotive Group 500 presented by Axalta and Valvoline on Sunday, June 7.
Live coverage of the night race starts at 9 p.m. ET on FOX, FOX One and INDYCAR Radio powered by OnlyBulls.
