Mark your calendars

For drivers, collectors and automobile enthusiasts, Aug. 13-16, 2025 has already been highlighted on their calendars for the historic racing event of the year — the Rolex Monterey Motorsports Reunion that will celebrate the 75th Anniversary of Formula One®. Complementing the F1 celebration will be many of the popular classes that have made the Rolex Reunion at WeatherTech Raceway Laguna Seca one of the world’s most prestigious motorsport lifestyle gatherings.

F1 Glory

Two exciting new additions to the Rolex Reunion will provide immense fan engagement. A special Formula One exhibition will showcase cars through the ages—from the earliest years to contemporary with modern technology—to honor the history and progression of these sleek, high-revving machines that have raced at the highest level of international competition.

International Race of Champions

The high-pitched revs of F1 will starkly contrast the deep-throated rumble of cars from the original IROC (International Race of Champions) series, which held races from 1973 to 2006. For the first time since 2002, IROC will return to the West Coast with an incredible display of authentic IROC race cars, with many being piloted by past IROC competitors from NASCAR, Formula One, IMSA, INDYCAR and Trans-Am.

The IROC series brought together the greatest drivers from all forms of motorsport to race purpose-built, identical cars to eliminate any advantages based on equipment. Various iconic makes and models were used during IROC’s 30-plus-year history, including Porsche Carrera RSRs, Chevrolet Camaros, Dodge Daytonas, Dodge Avengers, and Pontiac Firebirds.

Proper Vetting

The Reunion Advisory Council has spent considerable time reviewing past classes and analyzing the mix that will keep the on-track racing and immersive experience at its highest level. According to Reunion Advisory Council Chair Bruce Canepa, there were many factors to consider before finalizing the list.

“We carefully evaluate what groups are truly fan favorites and have significant cars that fully represent that era of racing to ensure a memorable experience for drivers and spectators,” said Canepa. “The Monterey hillsides will reverberate with the distinct sounds of historic F1 cars, while an additional 350-plus historic race cars will add to the diversity of the annual celebration of motorsport history.”

We require, and visitors expect, only the “best of the best” real cars with racing pedigree and historical significance.”
