at the
1965 Dutch Grand Prix. Introduced for the 1964 season, the 33 made its first appearance at the non-Championship
Aintree 200. Clark qualified fourth, and set fastest lap before retiring. The 33's first World Championship event was the
German Grand Prix. However, both Clark and his team mate
Mike Spence struggled with the car and it was not until the following year that it came good. Clark won the first event of 1965, the
South African Grand Prix and went on to take four more wins on the way to his second world championship. Clark missed the
Monaco Grand Prix (a race which he would never win) to race in the
Indianapolis 500, which he won. In 1965 a four-valve version of the Climax engine was used which had an increase in power (about - compared to the older Climaxes which gave about 200 bhp). However the extra power sacrificed reliability, and Clark retired from the final 3 races of 1965 after he'd wrapped up the title. The 33 was pressed into service with bored out 2 litre Climax V8 and
BRM V8 engines for the early races of 1966, until the 3 litre
Lotus 43 was ready. In 1967, with the new
Lotus 49 still suffering teething trouble, the 33s were deemed more suitable for the tight turns of Monte Carlo. Clark set fastest lap but retired his Climax-engined 33 while Hill drove the BRM-engined car to second place. The 33 was also campaigned in 1965 by
DW Racing Enterprises for
Paul Hawkins, and in 1965 and 1966 by
Reg Parnell Racing, however their car was actually a crashed 25 rebuilt as a 33, with a
BRM engine. The 33's final World Championship race was the
1967 Canadian Grand Prix, where privateer
Mike Fisher finished in 11th place. Fisher also qualified the car for that year's
Mexican Grand Prix, but engine problems prevented him from starting the race. The 33 also met with success outside of the World Championship with Jim Clark and Mike Spence each winning two non-Championship events, and Clark winning the
1967 Tasman Series. ==PC simulation==
