In late 1951, the Mercedes-Benz 300 S was launched as a particularly exclusive top-of-the-range model with a sporty touch. The two-door car was available as a coupe, convertible and roadster. In engineering terms, it was based on the 300 but was fitted with an even more powerful engine. Its elegant design took its cue from the classic lines of the 1930s rather than the Ponton models which followed soon afterwards.
