Introduced in 1954, the 220 model, also known internally as the 220 a (W 180), was the first Mercedes-Benz 6-cylinder model to feature a unitised-body design.
Its modern, spacious “ponton body”, which Mercedes-Benz had launched just six months earlier in the mid-range 180 model, offered hitherto unknown standards of spaciousness and comfort. With the launch of the revised and more powerful 220 S in 1956, the letter “S” became a permanent fixture in the names of high-end Mercedes-Benz models, underlining the special status of the 6-cylinder “ponton” saloon.
