With the 2026 Formula 1 season featuring a new American constructor, Cadillac, interest in the sport stateside is higher than ever. The U.S. now hosts three Grands Prix and has multiple constructor ties. Despite the strength of American motorsport, few U.S.-based teams have undertaken serious, long-term F1 efforts since the championship began in 1950.
Here are the top five American F1 teams, ranked by their success, impact, and longevity in the sport.
5. Parnelli (1974-1976)
Founded by racing legend Parnelli Jones, the team moved from successful IndyCar campaigns to F1. With Mario Andretti driving and ex-Lotus designer Maurice Philippe, the team showed promise with points finishes but folded in 1976 due to sponsorship issues.
4. Haas (2016-Present)
Gene Haas's squad is the most successful new F1 team in recent memory, scoring points on its 2016 debut. With a unique operational model leveraging Ferrari and Dallara, it achieved a best constructors' finish of 5th in 2018. The team continues to battle in the midfield.
3. Penske (1971, 1974-1976)
America's premier motorsport team had a brief but notable F1 stint. After a tragic start marked by driver Mark Donohue's fatal accident, John Watson delivered the team's sole victory at the 1976 Austrian GP before Penske focused back on IndyCar.
2. Shadow (1973-1980)
Don Nichols' team started as an American operation and produced fast, sleek cars. Despite poles and pace, its only championship win came with Alan Jones at the 1977 Austrian GP. The team was later absorbed after legal and financial struggles.
1. Anglo American Racers (Eagle) (1966-1968)
Dan Gurney's team, with its beautiful Eagle chassis and Weslake V12, made a major impact. Gurney's brilliant victory at the 1967 Belgian GP marked the first win for an American-built car in F1, securing its legacy despite a short lifespan.
