BIRMINGHAM, Ala. (October 18, 2025) – Alex Popow dominated at Barber Motorsports Park to earn his third win in Formula 4 United States Championship (F4 U.S.). After pacing both practices and earning the pole for MLT Motorsports, Popow (No. 55 Dr. Michael Thompson MS DDS PPLS / MLT Motorsports Ligier JS F422) led every lap in an all-green race to take the win with an 11.590-second margin.
Popow remains in a tight battle with Kekai Hauanio (No. 29 N-E-Where Transport / Crosslink Motorsports Ligier JS F422) for the Vice Championship, with the two now separated by just 3.5 points headed into tomorrow’s season finale. Starting third, Hauanio benefitted from a spin by series debutant Zach Fourie (No. 15 Kiwi Motorsport Ligier JS F422) to move into second, but had to hold off the advances of Caleb Campbell (No. 68 Kids Help Phone / Camtacc Properties / Legacy Foundation of Canada / LC Racing Ligier JS F422) and later Clemente Huerta Raab (No. 17 Velox USA / Kiwi Motorsport Ligier JS F422) to claim the runner-up position.
Huerta Raab was one of the biggest movers, gaining three positions throughout the 30-minute race to earn his sixth podium of 2025. Behind him, Fourie, finishing fourth, and Augusto Paschetta (No. 27 Scuderia Buell / Sport West / Bruno Maquinaria / Brapax Ligier JS F422), finishing fifth, earned top-five finishes in their series debut.
