The 75-lap race was won from pole position by Mario Andretti, driving a Lotus-Ford, with teammate Ronnie Peterson second and Jacques Laffite third in a Ligier-Matra.

Once again the new Lotus 79 demonstrated its speed, with Mario Andretti on pole and Ronnie Peterson alongside him on the front row, the Swede driving the 79 for the first time.

On race day, Hunt made a fast start to lead into the first corner from Andretti and Reutemann, with Peterson dropping to ninth.

This was how it stayed to the end, Andretti winning from Peterson in another Lotus 1–2, and Laffite taking the final spot on the podium.

Reutemann had a huge accident on lap 58 when his Ferrari flew 8 feet in the air, cleared the barrier and landed in the debris fencing.
