Turkish racing driver Ayhancan Güven won the Indianapolis 8 Hour on Saturday, Oct. 10, at Indianapolis Motor Speedway, crossing the line 56.209 seconds ahead in the No. 32 GMG Racing Porsche 911 GT3 R EVO.
Güven shared the car with Kyle Washington of the United States and Riccardo Pera of Italy. GMG Racing used an alternate pit strategy, and Güven’s pace put the car in the overall lead with a little under two hours remaining.
A historic win for Porsche and GMG

The victory gave Porsche its first overall triumph in the Indianapolis 8 Hour and marked GMG Racing’s biggest GT3 win. The result also secured the Pro-Am title for Washington.
Güven set the pace throughout the weekend, posting the fastest times in both practice sessions before qualifying second, narrowly behind Robby Foley’s Turner Motorsport BMW in Superpole.

A former Porsche Supercup and DTM driver, Güven is one of Türkiye’s most successful international racers, and his win drew celebration among Turkish Americans.
Record margin in a record field
The 56-second gap to the runner-up No. 69 Archangel Motorsports McLaren 720S GT3 Evo of Todd Coleman, Aaron Telitz and Tom Fleming was the largest winning margin in the event’s seven-year history. Güven, Pera and Washington completed 323 laps against a record 27-car GT3 field for a U.S. round of the Intercontinental GT Challenge, while Turner Motorsport’s BMW M4 GT3 Evo completed the overall podium.
GMG pitted earlier than its rivals just before the halfway mark, a call that left the Porsche nearly a minute clear once the stops played out. The car’s only setback was a five-second penalty for a pit-exit violation. The California-based team became the first GT World Challenge America squad to win the race outright; Pera was standing in for regular driver Tom Sargent.
“I came here two years ago with this team as the IGTC leader but unfortunately we had a really bad race. However, ever since that day, we’ve kept telling ourselves that we’d come back stronger,” Güven said. “Halfway through the race, it became clear to us that we might even be able to aim for overall victory. From that moment on, with Riccardo at the wheel, we really put our foot down, and in the end it worked out really well.”
The win was Güven’s third career Intercontinental GT Challenge victory and his first on U.S. soil. It also helped Porsche clinch its fourth IGTC manufacturers’ title, drawing level with Audi.
