Ari Sethi F4 California Series Sonoma Preview

TALENTED BAY AREA TEEN ARI SETHI CONTINUES HIS YOUNG RACE CAR DRIVER DEVELOPMENT PROGRAM

 

14 year old Ari Sethi has enjoyed a busy summer learning to race the JENSEN team's Formula 4 and Formula 3 race cars at circuits all across the United States.

Next weekend Ari will have a chance to show friends and family the progress with his race car driver development program as he competes in the final 2026 season round of the Formula PRO USA Championship Formula 4 race at Sonoma Raceway ( November 6-8 ).

Ari lives in Bay Area suburb Menlo Park, so a big crowd of supporters is expected as Sonoma Raceway located thirty minutes north of downtown San Francisco is Ari's hometown track.

Formula PRO USA Championship is comprised of six race weekends at circuits all located in California including WeatherTech Raceway Laguna Seca in Monterey and Sonoma Raceway.

Driving the #2 JENSEN Ligier Formula 4 race car, Ari made his debut in the penultimate round of the F4 California series at Laguna Seca in early October. With no previous karting experience, Ari faced a steep learning curve especially given the challenge of dealing with the significant elevation change at the Laguna Seca circuit.

Photo above captures how competitive the 2026 F4 California series has been, with race cars 3-wide in the turn one braking zone at the Sunday October 4th Laguna Seca race start. Ari put in two consistent race performances finishing 10th in both races, scoring two championship points.

Ari began his young race car driver development program completing a 2-day F4 Racing Camp at Buttonwillow Raceway in July 2026.

Ari showed impressive skills and a keen interest to become a race car driver, so together with his dad we created a customized young driver development program. In the three months that followed, Ari continued his driver development at tracks in Fort Worth Texas, Columbia South Carolina, and at the Austin F1 track Circuit of the Americas.

JENSEN team owner Eric Jensen offers insights, "Ari is an impressive young man. Despite his reserved nature, Ari is very charismatic with a wry smile and dry wit. He listens well, and is now setting fast lap times. At his most recent practice days at Buttonwillow Raceway, Ari won the test setting the fastest lap times versus two very quick and experienced young karters who were also testing with the JENSEN team during those days. Together with young team engineers Connor and Cameron, our team is all excited to see Ari make a big step up the grid at the Sonoma Raceway season finale next weekend."

Formula 4 is the entry level junior open-wheel race category on the FIA development ladder system intended to identify and train future drivers to compete in the Formula One World Championship. JENSEN owns four Ligier JS F4 pro spec race cars, and there are multiple championships across the USA that are terrific for new drivers to learn how to optimize their driving techniques and to gain competition experience.

Formula PRO USA Championship is one such championship, where the 2027 season will grow to feature seven race weekends at iconic California circuits once again including Laguna Seca and Sonoma Raceway.
