Pato O’Ward and Alex Palou split victories in the Sukup INDYCAR Race Weekend at Iowa Speedway, an event offering 550 laps of racing across two grueling races in as many days.

Chevrolet swept the podium in Saturday’s Synk 275 powered by Sukup, while Honda responded with a podium sweep of its own in Sunday’s Farm to Finish 275 powered by Sukup.

As the series heads north for Sunday’s Ontario Honda Dealers Indy Toronto (noon Et, FOX, FOX Sports app, INDYCAR Radio Network), three drivers re-enter the Power Rankings.

10. David Malukas (No. 4 Clarience Technologies Chevrolet; Last Rank: NR)

Malukas returned strong after missing the rankings post-Mid-Ohio. He finished 12th in Race 1 but climbed to fourth in Race 2, notching his third top-seven finish in the past seven events, highlighted by a runner-up finish in the Indianapolis 500 presented by Gainbridge. This marks his fifth time in the Power Rankings top 10 over the last six race weekends.

9. Christian Rasmussen (No. 21 ECR Splenda Chevrolet; Last Rank: NR)

The second-year driver impressed with top-10 finishes in both Iowa races – he was sixth in Race 1 and eighth in Race 2 -- making him one of just six drivers to do so. This is his second appearance in the rankings, having last been ranked 10th after World Wide Technology Raceway. All four of his top-10 finishes this season have come on ovals.

8. Josef Newgarden (No. 2 Astemo Team Penske Chevrolet; Last Rank: NR)

Newgarden led a combined 304 laps at Iowa, including 232 in Race 1 where he finished second. However, ill-timed cautions in Race 2 shuffled him back to 10th. Despite Iowa’s promise, recent results -- 22nd, 9th, 25th, 25th, and 27th -- keep his ranking modest. Still, this is his first Power Rankings appearance since he was fourth after the season opener at St. Petersburg.

7. Christian Lundgaard (No. 7 Arrow McLaren Chevrolet; Last Rank: 7)

Lundgaard rebounded from a 21st-place finish in Race 1 to finish sixth in Race 2, marking his second top-six result in the last three races. He also stood on the podium at Mid-Ohio with a third-place finish, his fourth podium of the year.

6. Felix Rosenqvist (No. 60 SiriusXM Honda; Last Rank: 5)

Rosenqvist continues a steady stretch with three top-seven results in the last four events. Highlights include a second-place finish at Road America and sixth at Mid-Ohio, keeping him solidly in the conversation near the top half of the rankings.

↓5. Kyle Kirkwood (No. 27 SukUp Honda; Last Rank: 3)

Kirkwood slips for the second straight weekend after a rough Iowa outing. A practice crash Saturday morning foreshadowed a 26th-place result in Race 1 and a tough 18th-place finish in Race 2. Still, his five top-eight finishes in the last eight races -- including three wins -- keep him in the top five.

4. Marcus Armstrong (No. 66 SiriusXM/Root Insurance Honda; Last Rank: 6)

Armstrong matched his career-best finish with a third-place result in Race 2 at Iowa, his second podium of the career (Detroit 2024). He’s surged from 16th to seventh in the points standings over the last six races, earning top-10s in all of them. This is his highest Power Rankings position to date.

3. Scott Dixon (No. 9 PNC Bank Chip Ganassi Racing Honda; Last Rank: 2)

Dixon followed up his Mid-Ohio victory with a runner-up finish to teammate Palou in Sunday’s Iowa race, giving Chip Ganassi Racing its second 1-2 finish in three events. With five consecutive top-10 finishes, Dixon remains firmly among the championship contenders.

↑2. Pato O’Ward (No. 5 Arrow McLaren Chevrolet; Last Rank: 4)

O’Ward finally broke through for his first win of the season in Iowa Race 1 and followed it with a solid fifth-place finish in Race 2. He now has eight top-seven finishes in the last nine races, including four top-two results. Notably, he also ranked second in the Power Rankings after Iowa last season.

↔1. Alex Palou (No. 10 DHL Chip Ganassi Racing Honda; Last Rank: 1)

Palou earned his seventh win of the season, which marks the first time since Al Unser Jr. in 1994 that a driver has won seven of the opening 12 races to a season. Unser won the championship by 47 points over Team Penske teammate Emerson Fittipaldi that season. Palou has scored nine top-two finishes this season and holds a commanding 129-point lead over O’Ward entering Toronto.
