SI's 1973 Sportsman of the Year, Sir Jackie Stewart of Scotland, won 27 Grand Prix races and three World Championships during his F/1 career, from 1964 through '73. A longtime commentator for ABC Sports, he remains a keen observer of the sport. Here are Sir Jackie's picks for the top five U.S. drivers in F/1 history, with the years in which they competed in Grand Prix racing, their number of GP wins and Stewart's comment for each.
1. Dan Gurney (below), 1959-69, four wins: "A world-class competitor, Dan is hands down the best American driver ever."
2. Mario Andretti, 1968-82, 12 wins plus the 1978 World Championship: "In the late '70s nobody in the world was better than Mario."
3. Phil Hill, 1958-67 three wins plus the 1961 World Championship: "Phil was a balanced driver and never backed down."
4. Eddie Cheever, 1978-89, no wins: "Eddie never won a Grand Prix, but he probably should have."
5. Danny Sullivan, 1983, no wins: "Danny had more desire than almost anyone I've ever met in the sport. He'd always give you his best."
