Formula 1’s rise in the United States isn’t slowing down. In 2023, ESPN’s average F1 race viewership hit 1.11 million, almost double the audience from 2018. With more American races, massive corporate involvement, and mainstream visibility, the U.S. is becoming a critical market for global motorsport.
The Miami Grand Prix (2022) and Las Vegas Grand Prix (2023) accelerated that growth, mixing elite racing with entertainment-driven fan experiences. Netflix’s Drive to Survive pulled in a younger and more diverse audience — now nearly 40% female — while attracting heavyweight brands like McDonald’s, Lego, Mattel, and LVMH. F1 is no longer niche culture in America; it’s a cultural anchor.
But one key element is missing: consistent American driver representation at the top.
And that’s where Cash and Roman Felber, 14-year-old identical twins from Cleveland, step into the picture.
Early Success in Formula 4
The Felber brothers started racing at age eight in Segway karts, and by 2023 they were already competing in the JSF4 Formula 4 Development Series at Circuit of The Americas. Their debut was a statement:
- Cash: two wins
- Roman: two second-place finishes
Both have competed in SKUSA KA100JR, USPKS KA100JR, the FARA F4 series, and have logged extensive Formula 4 testing across multiple U.S. circuits.
“Racing at our level is pretty competitive — if you’re one-tenth off, you could be fifth,” Roman says.
“There are 25 drivers trying to beat you. The top 5 is cutthroat,” adds Cash.
Training Like Pros
Under FLBR Motorsport, the twins follow a professional-grade training regimen designed for drivers aiming at Formula 1:
Physical Training
- Strength and conditioning
- Core development
- Neck-specific training for G-force resistance
- Cardio and endurance work
“I stretch before I go out, do reaction drills, and run through my pre-race mental checklist from my coach, Enzo Mucci,” Roman explains.
Cash focuses heavily on physical conditioning:
“Strength training, cardio, and neck work — it all matters when you’re pushing at high speeds.”
Simulator Work
Simulators aren’t games for these two — they’re essential tools.
Sim work helps them:
- Learn new circuits
- Review data
- Train racecraft
- Rehearse high-pressure scenarios
- Improve consistency
“We’re competitive even in the simulator,” Roman says.
“But if one of us is faster, we share data and help each other get better.”
Learning From the Best
The twins also have vision beyond their current level: Roman wants to race against Max Verstappen for his aggression and adaptability. Cash wants to go wheel-to-wheel with Lewis Hamilton — “the GOAT,” as he puts it.
Their respect for motorsport legends shows how seriously they treat the path ahead.
Why They Matter for U.S. F1
The U.S. motorsport ecosystem is changing. Young talents are targeting F1 earlier, training harder, and entering development pipelines that didn’t exist a decade ago. As F1’s popularity grows, the demand for American drivers grows with it.
Cash and Roman Felber aren’t just part of that movement — they’re becoming central figures in it.
Their mindset, competitiveness, and early results position them as two of the brightest American prospects in the global motorsport ladder. If their trajectory continues, the United States could soon have homegrown drivers capable of reshaping the sport’s landscape.
And based on everything we’ve seen so far, the future of American motorsport looks far stronger than people realize.
