The 1975 United States Grand Prix was won by Niki Lauda of Ferrari.
The race in United States of America was the last of 14 rounds of the 1975 season.
The 1975 United States Grand Prix was a Formula One motor race held on October 5, 1975, at the Watkins Glen Grand Prix Race Course in Watkins Glen, New York. It was race 14 of 14 in both the 1975 World Championship of Drivers and the 1975 International Cup for Formula One Manufacturers. It was the 25th United States Grand Prix since the first American Grand Prize was held in 1908 and the 18th since the first United States Grand Prix at Riverside in 1958.
The race was won by the new world champion, Austrian driver Niki Lauda driving a Ferrari 312T. Lauda took his fifth win for the season by a four-second margin over outgoing world champion, Brazilian Emerson Fittipaldi in a McLaren M23. Fittipaldi's West German team mate Jochen Mass finished third. The second place allowed Fittipaldi to confirm runner's up position in the points race after a half-season long battle with Argentine Brabham driver Carlos Reutemann, although Fittipaldi's McLaren team would fall one point short of overhauling Brabham in the Constructors battle to be second behind Ferrari.
