Race Report The main news before the Belgian Grand Prix was that the new Lotus 79 was now ready to race, and immediately Mario Andretti showed its pace by taking pole comfortably from Carlos Reutemann and Niki Lauda. He converted it to a first-corner lead, whereas Reutemann had a bad start and got swamped by the field, causing a chain reaction in which Lauda was hit by Jody Scheckter and had to retire. This left Gilles Villeneuve second and Ronnie Peterson third but neither could keep pace with Andretti who was able to drive away. The first 40 laps went without incident until Villeneuve suffered a puncture and had to pit which dropped him back down to fifth, and a few laps later Peterson also pitted for new tyres leaving the charging Reutemann second ahead of Jacques Laffite's Ligier. Peterson on the new tyres was much quicker and was able to pass them both in the closing stages, and Laffite made an attempt to pass Reutemann on the last lap but they collided and Laffite was out. Andretti cruised to an untroubled victory, with Peterson making it a Lotus 1–2, and Reutemann completing the podium.
