Pfaff Motors campaigned a
Porsche 944 in the inaugural
Rothmans Porsche Challenge in 1986, and remained with the series until it ended in 1990, with
Scott Goodyear winning the championship for the team in 1988. Pfaff entered the one-make series
Ultra 94 Porsche GT3 Cup Canada from 2012 until the series ended in 2019. However, when that series was replaced by
Porsche Carrera Cup North America in
2021, Pfaff had already moved to international racing in the
IMSA SportsCar Championship. Pfaff joined the
Pirelli World Challenge in
2018, with factory drivers and support from Porsche Motorsport NA, including reigning Cup Challenge Canada champion of 2017
Scott Hargrove moving across to that entry. The team also fielded an entry in the supporting
GT4 class. From 2019 on, Pfaff have campaigned in the
IMSA Sportscar Championship, including the
24 Hours of Daytona, with a
Porsche 911 GT3 R. Pfaff's North American racing in 2020 was heavily affected by the impact of the
COVID-19 pandemic. Pfaff ran in that season's
2020 24 Hours of Daytona but were otherwise only able to enter the
Petit Le Mans round, and missed the remainder of the rearranged rounds. The team, and commercial partners, competed in the domestic
Canadian Touring Car Championship instead, using the experienced IMSA driver
Zacharie Robichon in a coaching role with young driver
Zachary Vanier. The 17-year old secured the championship title with Pfaff. Pfaff have appeared in a "Plaid Porsche" livery from 2019 to 2023. The idea started as a joke in the workshop; the car for the
2020 24 Hours of Daytona arrived late, forcing the team had to work over the Christmas holiday period in order to meet logistics deadlines. In the workshop many of the crew wore plaid shirts and marketing director Laurence Yap suggested wrapping the car in plaid too. On Oct 9, 2023, Pfaff Motorsport announced a switch to McLaren, campaigning a
720S GT3 Evo as an official manufacturer nominated entry to the GTD Pro class in the IMSA WeatherTech SportsCar Championship. This included a switch away from the full plaid livery, instead creating a "ghost plaid" within a livery aligned with McLaren's "papaya and blue," according to designers Dakins Design. Note: the Pfaff businesses have a more recent McLaren relationship in addition to the founding Porsche relationship, and have previously campaigned McLaren
GT4 chassis with IMSA. In 2025, Pfaff switched manufacturers again, purchasing a
Lamborghini Huracán GT3 Evo 2 to continue competing in the GTD Pro class in IMSA. With the switch to Lamborghini, the team also reverted back to their full plaid livery that they had previously used with Porsche. == Racing record ==
