Cash and Roman Felber Make Race Debut Competing in the F4 U.S. Development Series at Austin F1 Circuit

November 14, 2023 - 13-year-old twins Cash Felber and Roman Felber do most things together in life, and for the past year both have focused on learning the art of being fast.

Since January 2023, Cash and Roman have been driving F4 U.S. Championship Ligier race cars at circuits across North America with a view to learning and perfecting the necessary skills as they aspire to become professional race car drivers. Part of a customized JENSEN young driver development program, Cash and Roman made their car racing debut competing in the F4 U.S. Development Series event at the 2023 season finale at Circuit of The Americas--racing on the same circuit where Formula One drivers competed just two weeks before.

F4 U.S. Championship is the first American step on the Formula One World Championship development ladder. The minimum age to compete in the F4 U.S. Championship is 15, so the F4 U.S. Development Series provides younger drivers, including the 13-year-old Felber twins, with an opportunity to gain racing experience in advance of their rookie seasons competing in the F4 U.S. Championship,

Recently it was announced that the 2024 development series will be branded as the Ligier JS F4 Series. The 2024 schedule will feature five race weekends at famous road course circuits across North America, starting in New Orleans in April, and followed by races at Road America, Mid-Ohio and New Jersey. The championship will conclude at VIRginia International Raceway in October, where the 2024 Ligier JS F4 Series Champion will be awarded a prize package to graduate to racing in the 2025 F4 U.S. Championship.

Cash Felber (pictured) scored victories in both races at the Austin F1 circuit, with his brother Roman Felber finishing second in both events. Beyond being proficient on track, the Felber twins’ achievement is further bolstered by sponsorship from a suite of brands, including: Primal Life Organics, IVI Smile, Life Force Water, Snooze Mattress, and ProSim.

Team owner and driver coach Eric Jensen stated, "The Austin race weekend was an ideal opportunity to provide the Felber twins with their first F4 race weekend. The boys started driving at one of our Racing Camp programs in January, and since then have been testing almost every month at circuits across the country."

Jensen continued, "Being safe is always our main priority when developing young drivers, especially when the kids are as young as the 13-year-old Felber twins. They have both steadily improved their pace and have consistently shown their ability to make good decisions while running with other race cars on track. So it was with great pride to see both kids excel on track in their debut race weekend, and a just reward to see them both enjoy their first podium experiences together."

The Felber twins will return to their Ligier F4 cockpits in December with more testing at Circuit of The Americas in Austin, Texas, followed by additional race competitions at Homestead-Miami Speedway in January.
