The 1982 Caesars Palace Grand Prix was a Formula One motor race held on September 25, 1982 in Las Vegas, Nevada. It was the sixteenth and final race of the 1982 FIA Formula One World Championship, and the second and last F1 race to be held in Caesars Palace. The 75-lap race was won by Michele Alboreto, driving a Tyrrell-Ford. Alboreto scored Tyrrell's first victory since the 1978 Monaco Grand Prix, becoming the eleventh different winning driver of 1982 while Tyrrell became the seventh different winning constructor. John Watson finished second in a McLaren-Ford, with Eddie Cheever third in a Ligier-Matra. Keke Rosberg finished fifth in his Williams-Ford to secure the Drivers' Championship, with Ferrari taking the Constructors' Championship despite neither car finishing in the top six. This was the last F1 race for 1978 World Champion Mario Andretti. It was also the last race for the Ensign and Fittipaldi teams, the last for March until , and the last for Matra as an engine supplier. Qualifying report For the first time since the World Championship began in 1950, a country hosted three rounds in the same season in 1982. The final race of the year, and the third in the US, would once again decide the Championship. Keke Rosberg of Williams had 42 points, to 33 for McLaren's John Watson, and needed to finish sixth or better to secure the title. Meanwhile, the race was former world champion Mario Andretti's final grand prix. The course's tight turns and short straights allowed the non-turbo cars to be more competitive than usual, with Michele Alboreto's Tyrrell and Eddie Cheever's Talbot Ligier fastest among them. The turbocharged Renaults of Alain Prost and René Arnoux took first and second positions in qualifying, more than eight-tenths clear of Alboreto. The two Championship contenders, Rosberg and Watson, meanwhile, were in sixth and ninth places respectively, separated by the Ferraris of Mario Andretti and Patrick Tambay. Championship permutations Rosberg and Watson both entered this race with a chance of winning the Drivers' Championship. Rosberg (42 points) needed either 6th or higher Watson 2nd or lower Watson (33 points) needed to win the race, with Rosberg 7th or lower. Had this happened, both drivers would have finished with 42 points, and Watson would have been champion by virtue of having three wins to Rosberg's one.
