The Honda S600 is a 2-door sports car built between 1964 and 1966. Initially available as a roadster, a coupe variant started to be offered in 1965. Powered by a 606cc inline 4 engine, the S600 was the first heavily marketed Honda automobile. The S600 was offered in two trim levels, standard and the SM600, which featured numerous comfort and usability improvements over the standard model. The S600 was built until 1966, when it was replaced by the S800. 11,284 examples of the S600 were built, of which only 1,800 were coupes.
