Bobby Unser

Bobby Unser, an American driver born in 1934, made a single Formula 1 World Championship start, driving for BRM in 1968. The appearance came when he was thirty-four years old.

The outing brought no championship points, and his Formula 1 record stands at that one start. Unlike the American drivers of the 1950s whose championship statistics came via the Indianapolis 500, Unser's sole appearance was in a conventional Grand Prix with a works British team.
