The 2025 Rolex Monterey Motorsports Reunion was held from August 13–16, 2025, at WeatherTech Raceway Laguna Seca. This historic competition event celebrated the 75th anniversary of Formula 1 and reunion of the IROC (International Race of Champions series).
55 historic F1 cars were featured on the track and on display, including vehicles from the 1950s up to a 2024 McLaren. Drivers like Takuma Sato drove historic F1 cars, such as the Williams Honda FW11, for demonstration laps.
IROC reunion: For the first time ever, all seven generations of IROC cars raced together in the same race. Racing legends, including Jeff Gordon, Kurt Busch, Danny Sullivan and Jenson Button, took part in the races. The Unser Family Cup race was won by Tomy Drissi in a 2006 Pontiac Firebird.
Featured race groups: In addition to the special celebrations, more than 400 historic racing machines competed in 14 race groups, showcasing a diverse range of motorsport history.
