Lotus 72 developments—
The Lotus 72, a brilliant design by Colin Chapman, was raced for no less than 6 years, which is incredibly long by any racing standards. The Lotus 72 was very successful, with Jochen Rindt and Emmerson Fittipaldi winning the World Championship for drivers in 1970 and 1972 respectively, and Lotus winning the Constructors' title in 1970, 1972 and 1973. Between 1970 and 1975 the car was frequently modified to keep it competitive and to meet new regulations. Some of the many changes made to the Lotus 72 in the course of its long racing career include different rear wings, enlarged air intake boxes, revised track and suspension settings, relocation of the battery, and a different wheelbase. The cars always looked immaculate, especially in their stunning JPS livery.
In 1975 the Lotus 72 was fitted with a larger air intake box and a larger rear wing.
