This was a predecessor to Honda’s first true production-ready, prototype auto, which made its public debut at the 1962 Tokyo Motor Show. Powered by an all new, DOHC, water-cooled, in-line 4 cylinder engine with four carburetors, it produced 33 horsepower from 356cc at an unheard of 9,000 rpm. The car also featured a steel body, a five speed manual transmission, and for an automobile, a very unusual chain final drive utilizing aluminum swing arms which served double duty as chain cases, and also acted as trailing arms for independent rear suspension. The S360 never actually went into production because of conflicts with the contemporary Japanese Government’s size and displacement rules, and restrictive tax laws.
