Pfaff Motorsports to withdraw from IMSA at season's end

Canadian GTD Pro team Pfaff Motorsports is set to scale back its racing operations and withdraw from the IMSA WeatherTech SportsCar Championship at the end of the season, RACER has learned.

The team, owned by prominent auto dealer Chris Pfaff, will continue racing until the end of the current season with its Lamborghini Temerario GT3, before winding down its operations and resetting its focus.

Chris Pfaff's choice to step back from high-level sportscar racing comes in the wake of his becoming a partner in the new ownership group that took charge of Canadian Tire Motorsport Park at the end of 2025. He plans to shift his primary focus in motorsport to helping operate the circuit and act on the group's long-term investment strategy for the site.

This decision was made last month, with the team's full-time members learning the news last Monday before setting up at Road America for the IMSA Endurance Cup race, which it went on to win. The fan-favorite outfit's full-time staff have begun looking for solutions to keep themselves in the sport in 2027.

"We've had a great run, I've really enjoyed being part of IMSA," Chris Pfaff told RACER. "But we've made an investment in CTMP, and I have plans to do a lot to that facility, invest in infrastructure and make it a track used for a number of things in motorsport and car culture; we want it to be a 12-month-a-year facility.

"However, we are looking at other options for the team. We couldn't look to commit for next year, so it was best to let everyone know and give them a lot of notice. But I haven't shut the door. I'm looking at other possibilities, which I'm excited about, but there's nothing I can speak of at this time. I want to continue to work in motorsports, not just as a track owner, but in other areas in IMSA and other places.

"We've lost a lot of development opportunities for young kids in the sport. I own a karting facility, my son is a go-karter, and we're trying to give opportunities for kids after karting to step up. It's a passion and a goal. I want to give back and do it in a commercially reasonable way.

"Pfaff Motorsports will continue; it will move on and develop. I hope to make it a bit broader in what it does."

As for the team's relationship with Lamborghini, Pfaff said he wasn't sure what the future holds.

"It probably (ends at the end of the year), but you never know," he said. "We're going to have to step back, officially, at this point, but the Lamborghini deal two years ago came together very quickly. We're working on stuff. It's a reset. Whether it's next year, I'm not sure, but we'll be back."

The Toronto-based team joined the IMSA SportsCar Championship back in 2019, and clinched GTD and GTD Pro titles in 2021 and 2022, respectively, as a Porsche customer team. It then shifted to racing with McLaren in 2024, before joining Lamborghini Squadra Corse's stable in 2025 and being tasked with debuting the Temerario GT3 in North America this year.

The team, fresh from its first win with the Temerario GT3, currently sits seventh in the GTD Pro Championship standings with three rounds remaining.

RACER reached out to Lamborghini Squadra Corse for comment on this news and the future of the brand in GTD Pro, and it declined to comment.
