Remarkable Racers: The Ten Best American Race Cars
Duesenberg GP
Debut Year: 1921

That 1921 Grand Prix win that I mentioned? That was the work of the man-machine combo that was Jimmy Murphy and the Duesenberg GP. In the 1921 French Grand Prix, also held at Le Mans, Murphy stormed to victory, finishing a full 15 minutes ahead of his next competitor, Ralph DePalma. While Duesenberg is a name that’s long since vanished into the mists of time (it has been defunct since 1937), it’s one that deserves more recognition. As one of the small companies that emerged when the car was really beginning to surge in popularity, the company produced a series of cars powered by a 24 horsepower flat-twin engine.

For the Grand Prix, the company got serious, producing an F1 car that produced 115 horsepower, thanks to a three-liter straight-eight. The team that won the 1921 Grand Prix was managed by former Vanderbilt Cup winner, George Robertson. What is even more impressive, on the driver side of things, is that Murphy was still recovering from injuries sustained in a crash when he trounced the competition, and became the only American driver in an American car to win the French Grand Prix.
