Super Beetle Technical Information

Although they looked the same as previous models, the 1302 and 1303 ‘Super’ Beetles were the most radical reworks of the car during its long life. MacPherson strut front suspension was adopted, which allowed more front boot space (and thus provided the easiest way to tell these cars apart, by their bigger and more rounded bootlid) and improved handling. The struts also allowed front disc brakes to be fitted too. The 1303, from 1972, had a more safety-conscious padded dashboard and wraparound windscreen, plus bigger tail lights.
