Masters Historic Racing will partner with the Yokohama Drivers Cup USA for a grand, dual-series 2021 season finale at Sonoma Raceway, October 15-17. Given the 2.52-mile road course’s lush wine country setting, it’s a fall weekend rich with on- and off-track activities no enthusiast should miss.

At Sonoma, the three Masters U.S. series – Historic Formula One, Endurance Legends and new-for-2021 Formula Atlantic Plus – will join the Yokohama Driver’s Cup GT3, GT and GT Celebration classes in a packed weekend event schedule.

The event, run by Competent Motorsport, marks the finale of the eight-weekend / 22-race 2021 Yokohama Drivers Cup USA series managed by the California-based agency.
