Here is Jim Clark cutting through the difficult Tarzan Corner on the seaside Zandvoort circuit in Holland to win the Dutch Grand Prix on July 18, 1965. This was the last year of the 1.5 liter engine formula. At this point the suspension developments over the past several years, led by the Lotus 25 in 1962, had exceeded the challenge of the power available and a new and far more powerful 3 liter formula would commence in 1966. Here Clark has the Lotus 33, a development of the still-being-used 25, and with the latest iteration of the 1.5 liter Climax V8 engine, then producing just over 200 hp at 10500 rpm.
The fast Zandvoort circuit had a lap length of just over 2.6 miles which allowed the 1965 F1 cars to lap at just over a 100 mph average. Situated just north of the beach community of the same name, the track had been created using some roads put in by the German military during the war. Johannes Hugenholtz was involved in its creation, acted as the circuit’s director for many years and subsequently designed a number of other F1 circuits. His son Hans has raced historic cars for many years. After having been closed for reconstruction from time to time, the picturesque Zandvoort circuit was reopened for racing, but with a less open and sweeping character and rather slower than its former layout.
Clark was on his way to a terrific 1965 when he would win the World Championship with six victories, the maximum which could be counted, including the Zandvoort race, and also won the Indianapolis 500 with a Lotus 38, leading for 190 of the 200 laps.
