The Mercedes-Benz W180 is a line of full-sized luxury cars produced by Mercedes-Benz between 1954 and 1959, which included an inline 6-cylinder saloon, coupé, and convertible. The four-door 220 a sedan was produced from 1954 to early-1956. It was succeeded by a slightly modified, more powerful 220 S in early 1956. A two-door cabriolet and coupe joined the line in mid-1956; all three models were produced through the end of the W180 run.
A fuel-injected version of the 220S was introduced in October of 1958 as the W128, produced also in four-door sedan and two-door coupe and cabriolet through November 1960.[3]
The W180 series was one in a range of Mercedes-Benz models to informally receive the "Ponton" nickname, derived from its unibody-type, pontoon-shaped exterior styling, which carried through into the subsequent W128 line.
