Trackhouse Racing drivers Shane van Gisbergen and Connor Zilisch are poised to continue their spirited rivalry this weekend at the Circuit of the Americas (COTA), with a focus on the Saturday Focused Health 250 NASCAR O’Reilly Auto Parts Series race before Sunday’s NASCAR Cup Series main event. Their competition reflects a growing Trackhouse Racing rivalry that has attracted much attention ahead of the high-profile event.
A Look Back at the Drivers’ Past Battles and Recent Performances
Connor Zilisch, age 18, is the reigning champion of the Focused Health 250, having secured pole position and narrowly defeated NASCAR Cup driver William Byron last year by a margin of 1.639 seconds. Shane van Gisbergen, relatively new to the O’Reilly Auto Parts Series with just three starts last season, managed to outpace Zilisch on the Chicago Street Course, with Zilisch finishing second in that race.
Their rivalry intensified at Sonoma Raceway, where Zilisch edged out van Gisbergen by 0.438 seconds in July. Their competition hit a dramatic moment during the rubber match at Watkins Glen, when they collided at Turn 7 on Lap 65. Zilisch recovered to win that race, while van Gisbergen slipped to 31st place.
Zilisch’s performance in 2025 was remarkable, claiming 10 victories in the O’Reilly Auto Parts Series with JR Motorsports before moving up to the Cup Series with Trackhouse this year. This year’s showdown promises to extend their ongoing contest on track.
Changes to the Circuit and Its Impact on Racing Dynamics
NASCAR has adjusted the traditional 3.426-mile Grand Prix layout at COTA by shortening the track to 2.4 miles, cutting out the long backstretch. This modification creates more opportunities for passing and enhances the racing spectacle.
COTA is just super-fun, especially since they shortened the course,
said Zilisch.
“I really enjoy the shortened course. It has created really good racing and has a short-track type feel to it now.”
?Connor Zilisch, Driver
You don’t really have straightaways anymore, except for the front straightaway. It’s just so unique. You’ve got a new passing zone now with Turn 6A and that cut-through is a great passing zone. As a driver, you’re doing more, more often. You’re turning more, and you’re in a corner more often. It’s a lot of fun.

Potential Challengers and Upcoming Implications for the Series
While van Gisbergen and Zilisch have dominated headlines, Sam Mayer presents a formidable challenge as a series regular who might disrupt the Cup drivers’ reign. Mayer boasts four top-10 finishes in four appearances at COTA, including a best finish of third place last year, signaling his readiness to contend with the Trackhouse Racing drivers.
This weekend’s events at COTA will not only test the racing skills of these drivers but also have meaningful implications for the ongoing O’Reilly Auto Parts Series season. As the rivalry deepens, the outcome of these races could shape the momentum for Trackhouse Racing’s competitors moving forward.
