Alex Palou secured his historic fourth IndyCar title during the 2025 Grand Prix of Portland when rival Pato O’Ward suffered a sudden mechanical failure early in the race. The unexpected power loss on O’Ward’s Arrow McLaren car dashed his championship hopes just 21 laps into the event, effectively handing Palou the championship lead.
O’Ward had rejoined the race after his first pit stop on lap 16, where his team switched off the alternate tires. This stop came shortly after a caution period triggered by Conor Daly’s severe crash on lap 15. Daly of Juncos Hollinger Racing had been battling Christian Rasmussen of ECR before the incident, which occurred as Rasmussen clipped Daly entering Turn 8.
At the lap 21 restart, O’Ward, who began the race on pole position, suddenly experienced a total loss of power. The lights on his steering wheel went dark, prompting commentator Townsend Bell to suggest the issue might be “terminal” for the Mexican driver‘s race and championship ambitions.
Despite managing to coast back to the pits, O’Ward’s No. 5 team began repairs immediately. Yet, with his championship pursuit on the line, the mishap effectively gifted the title to Palou. After returning to the track, O’Ward was nine laps behind the leaders, with no chance of catching up.
Arrow McLaren issued a statement to reporter Marshall Pruett explaining the failure:
“The No. 5 Arrow McLaren Chevrolet was forced to return to pit lane on lap 22 for repairs after a wire connected to the DI box malfunctioned.”

The team replaced the DI box and the associated wiring before sending O’Ward back out, but by then the points deficit was insurmountable. Arrow McLaren Team Principal Tony Kanaan described the incident as “no one’s fault” and said simply, “it just wasn’t our day.”
Before the Portland race, O’Ward trailed Palou by 121 points in the championship standings. To stay in contention for the 2025 title, he needed to finish ahead of Palou and cut the gap to under 108 points. Conversely, if Palou finished anywhere ahead, the championship would be his. With O’Ward’s setback on lap 22, Palou’s lead became untouchable, cementing his championship status before the race concluded.
Alex Palou’s Place Among IndyCar Legends Recognized After Portland Triumph
Alex Palou’s dominance this season with Chip Ganassi Racing has been remarkable. Aiming for his third consecutive championship and fourth overall, his achievement at Portland catapults him into an exclusive group of IndyCar greats. By clinching the title midway through the race, Palou matched the four championships earned by Mario Andretti, Sebastien Bourdais, and Dario Franchitti.
This season, Palou has claimed victory in eight races, including a breakthrough win at the prestigious Indianapolis 500 in May. His consistent performances have established him as one of only four drivers in IndyCar history to win three straight championships, joining Ted Horn, Bourdais, and Franchitti in this elite circle.
The 2025 season has underscored Palou’s skill and tenacity, confirming his status as a dominant force in the sport. His success not only elevates his personal legacy but also bolsters Chip Ganassi Racing’s continued prominence in IndyCar competition.
