Sadly for Giacomelli and Alfa fans, there would be no fairytale ending; the car led the first 31 laps – a fraction over half distance – until the V12 179 suffered electrical failure.
With Giacomelli sidelined, Jones took over at the front having worked his way up from fifth on the grid in the Cosworth DFV-powered FW07B. He controlled the race for the remaining 28 laps to take his fifth win of the year to add to victories in Argentina, France, Britain and Canada. Reutemann made sure of the team’s second successive one-two, 4.2 seconds adrift. The podium was completed by Ligier’s Didier Pironi in his final race for the French team before joining Ferrari for 1981.
With Reutemann’s Monaco win making it six for the year, Williams took twice as many victories as rivals Brabham and Renault, which accounted for the team scoring nearly twice as many points as anyone else.
