For the first half of the British Grand Prix it had looked fairly straightforward, Jim Clark pulling away in his Lotus 33 with only Graham Hill able to stay vaguely in touch. After 50 of the scheduled 80 laps, however, Clark’s engine developed a slight misfire which became ever more audible. He was well clear of the field by then, but BRM gave Hill signs of encouragement via his pitboard, alerting him to the leader’s potential frailty.
As the gap between them diminished, Hill – in pursuit of his first British GP victory – strove ever harder. Clark, meanwhile, had a supplementary concern, for he was now losing oil. The solution? He coasted around corners and used his engine hard only on the straights, when the cockpit gauge indicated he had sufficient pressure. Hill had him almost in sight at the start of the final lap, when he broke the track record, but Clark nursed his Lotus home with 3.2sec to spare.
Hill never would win his home race.
