The car took Lotus' first F1 victory, by Innes Ireland in the non-championship Glover Trophy, on 8 April 1960. Its first World Championship win happened six weeks later, on 29 May, albeit by privateer Rob Walker, who leased the car from Chapman. Driven by Stirling Moss the car took a dominant win at the 1960 Monaco Grand Prix. It was an early taste of things to come. Moss also won the United States Grand Prix at the end of the season helping Lotus finish second in the constructors' championship.
