half-distance, Jones still led comfortably, with Regazzoni still second and well clear of Arnoux, and Laffite moving ahead of the Ferraris into fourth. Then, approaching Woodcote at the end of lap 39, Jones's engine failed, a water pump problem causing it to overheat. Six laps later, Laffite also retired with engine trouble. This left only four drivers on the lead lap - Regazzoni, Arnoux, Scheckter and Villeneuve - with Jean-Pierre Jarier up to fifth in his Tyrrell and Watson sixth. The Ferraris were also struggling on Michelins, and Villeneuve pitted for new tyres on lap 50, before stopping with fuel vaporization problems five laps from the end. Scheckter, meanwhile, was lapped by Regazzoni on lap 56, before Jarier and Watson passed him in the closing laps. Regazzoni eventually took the chequered flag 24 seconds ahead of Arnoux, giving Williams their first Formula One victory. It was also Regazzoni's fifth and final win and, to date, the last win in F1 for a Swiss driver. After Jarier, Watson and Scheckter came Jacky Ickx, taking the final point in the second Ligier. This was the first Grand Prix on which James Hunt, who had retired from racing the previous month, commentated alongside Murray Walker for the BBC's Grand Prix programme. Classification Notes – Elio de Angelis finished 11th, but received a one-minute time penalty for a jump start.
