Austin, Texas. TOPP Racing clinched back-to-back Porsche Carrera Cup North America championships in the season finale at Circuit of the Americas, led by race two winner and Mobil Pro class driver champion Tyler Maxson. His ninth victory of the season, plus an additional win by teammate and Rookie of the Year winner Cole Kleck, sealed the entrant title as well.
Janne Stiak (ACI Motorsports) won Saturday’s race overall. James Sofronas (GMG Racing) and Solairus Aviation Masters champion Patrick Mulcahy (ACI Motorsports) split their class race wins, while Scott Blind of Ruckus Racing swept the weekend in the Solairus Aviation Masters class.
Marco Cirone, who had already clinched the Masters Championship with ACI Motorsports, did not start Sunday’s race after being collected in an on-track incident the day before.
Race 1. Saturday, October 24.
Porsche Motorsport North America Junior Driver Janne Stiak (ACI Motorsports) won the battle and the race on Saturday at Circuit of the Americas, while fellow PMNA Junior Tyler Maxson (TOPP Racing) won the war and the season-long Mobil Pro Class championship with a third-place finish.
James Sofronas (GMG Racing) made his return to the paddock after an early-season injury and earned a victory in the Solairus Aviation Pro-Am class. Scott Blind (Ruckus Racing) earned his first Solairus Aviation Masters class win since Round 3 at Miami in May.
Stiak’s No. 40 Porsche 911 Cup started second alongside Maxson. When Maxson ran a defensive line to the inside into the first corner, Stiak pinched the champion-elect to the inside of the corner without contact. The clean move allowed Stiak to carry momentum through the corner, taking the lead. That also allowed Aaron Jeansonne to move his No. 24 Porsche 911 Cup around Maxson just two corners later, relegating Maxson to third.
Stiak opened up a gap of more than two seconds before a full course yellow bunched the field on lap seven for contact between the Pro-Am car of Josh Conley and Masters class driver Dan Drohan. Though neither car was able to continue, Drohan was assessed a 30-second penalty for the incident.
Stiak led the field back to the green flag with 10 minutes to go and championship contenders Jeansonne and Maxson on his bumper. While Stiak and the front of the field climbed the hill to Turn One, contact between Masters drivers Matt Smith (ACI Motorsports) and Kyle Washington (GMG Racing) turned each to the inside wall on the front straight and collected Marco Cirone (ACI Motorsports).
The incident brought out another safety car, ended the race for all three drivers. Time expired during the extensive cleanup, ending the race under yellow flag conditions.
Jeansonne’s runner-up finish was his eighth of the season and 13th total podium.
Maxson secured his ninth podium finish of the season – though his previous eight were wins. The total, along with the bonus points for earning Sunday’s Race Brew pole position, was enough to secure the title.
Sofronas returned to Porsche Carrera Cup North America for the first time since the season opener and didn’t miss a beat, earning his ninth career series win. He started Saturday’s race on the class pole and pulled held the lead early until the full course caution ended the race early.
The Pro-Am win by Sofronas broke a season-long streak for Patrick Mulcahy, who clinched the championship early by winning each of the first 14 races of the season. The ACI Motorsports driver pushed Sofronas during the green flag run, ultimately finishing second.
Kellymoss driver Steve Wetterau finished third in his first race since a pair of class runner-up finishes at Long Beach in April.
Scott Blind earned his third Masters class win of the season on Saturday. Blind was the top qualifier in the class with his No. 45 Ruckus Racing Porsche 911 Cup, and his position out front early helped his fortunes late in the race.
The top five Masters class cars, led by Blind and followed by Rob Walker (JTR Motorsports Engineering), Washington, Smith and Cirone, were in order when the initial full course caution came out. Blind and Walker were each in front of the incident behind them that ended the day for Washington, Smith and Cirone on the restart, keeping them in the clear and able to grab the checkered flag.
Race 2. Sunday, October 25.
Tyler Maxson put an exclamation point on a Porsche Carrera Cup North America championship season on Sunday at Circuit of the Americas, adding a season-ending win to his Mobil Pro Class title.
Solairus Aviation Pro-Am class champion Patrick Mulcahy (ACI Motorsports) earned his 15th class win in 16 races. Scott Blind (Ruckus Racing) stood on the top of the podium in the Solairus Aviation Masters class for the second consecutive day.
Maxson had mixed feelings after Saturday’s third-place finish, which he achieved through conservative driving. That all went out the window Sunday, as the newly crowned champion drove to an impressive 6.077-second win at Circuit of the Americas.
His No. 77 TOPP Racing Porsche 911 Cup started on the Race Brew pole, just like Saturday’s race. But unlike Saturday, Maxson held off the charge from second-starting Janne Stiak (ACI Motorsports) and led the opening corners.
Maxson rattled off 16 strong laps in clean air, slowed only once during a brief full course caution period early in the race which came after Sabré Cook and Alan Metni made contact and each pulled off course. Maxson ran the quickest lap of the race and led the field across the finish line.
Meanwhile, Stiak and Callum Hedge of JDX Racing fought a fierce battle behind Maxson. The two young drivers are champions in their own right – Stiak won the Porsche Carrera Cup Middle East title in the 2024 / 2025 season while Hedge captured the Porsche Carrera Cup Australia championship a year ago. Hedge and Stiak swapped second place three times on the opening lap alone, which allowed Maxson to slip ahead.
Though Hedge was in front on the track, he was assessed a 10-second penalty during the race for track limit violations, allowing Stiak to grab the silver medal.
The final podium position was a four-way fight, led early by Aaron Jeansonne (Kellymoss) and followed closely by Jared Thomas (JTR Motorsport Engineering), Paul Bocuse (Kellymoss) and Cole Kleck (TOPP Racing). Jeansonne ran wide in Turn Nine on lap nine, allowing all three to pass and giving the podium nod to Thomas.
The No. 54 ACI Motorsports Porsche 911 Cup driven by Mulcahy finished second for the first time on Saturday after winning the opening 14 Pro-Am class races. He corrected that error on Sunday, returning to the top step of the podium.
Mulcahy started second in the class but moved to the front when the contact between Cook and Metni also sent Pro-Am class Race Brew polesitter James Sofronas off track. While Sofronas dropped to the rear of the field on the opening lap, Mulcahy put his head down and began moving forward overall.
The ACI Motorsports driver slipped through the Masters class battle and a few Pro class cars while Sofronas rallied from the back. Mulcahy made his way through, finishing first in class, 11th overall, and more than four seconds in front of Sofronas in second.
The win was the 15th of the season in class for Mulcahy, and one of his more challenging victories and deepest class fields of the season. It also came in front of family and friends – while Mulcahy now calls Southern California home, he was born and raised in Texas.
Scott Blind swept all three Porsche Carrera Cup North America runs at Formula One Grand Prix weekends in 2026 with a Sunday win.
Blind’s No. 45 Ruckus Racing Porsche 911 Cup led every lap in Austin on Sunday to lead the Masters class handily. He started on the Race Brew pole and stayed in front of a class field that was depleted in race two following a race one incident that prevented three cars from starting.
In addition to this weekend’s races at the United States Grand Prix, Blind also won at the Miami Grand Prix in May.
A hard-charging Rob Walker (JTR Motorsports Engineering) nearly stole victory from Blind at the finish, running the final lap nearly a second quicker than Blind to close the final margin to just three tenths of a second.
