The 2025 Formula Pro USA Western Series was the sixth season of the championship for Formula Regional and Formula 4 cars established in the West Coast of the United States. The championship was promoted and organized by Exclusive Racing and Exclusive Auctions, and was ran under the same sporting regulations as the FIA-sanctioned Formula Regional Americas Championship and Formula 4 United States Championship.
It began in March, with the championship spanning six weekends until November. [1] World Speed Motorsports driver Larry Schnur claimed the FPUSA-3 title with two races to spare when his closest competitor, Charles Duncan, did not enter the final round. The FPUSA-4 class was won by Ridgeley Welsh, also driving for World Speed Motorsports, while Kiwi Motorsport's Carolyn Fitzgerald took victory in the Women's Racing Series class.
Drivers were able to enter either the FPUSA-3 or the FPUSA-4 class, with the former using a Ligier JS F3 car and the latter a Ligier JS-F4 car. All cars were powered by Honda and used Avon tires. [2]
