The Honda S360 was introduced in 1962 as a prototype car. These four seated convertible sports cars that had a top speed of 100km/h. This was achieved with a new double overhead cam engine with four carburetors, it’s inline four-cylinder engine was water cooled and ran at 9000rpm to make 33hp from 356cc’s of motor.
It had a 5-speed manual transmission with a chain driven final drive with rear independent suspension. The S360 never went into production because of Japanese restrictive displacement laws. Future changes of the S360 would increase the engine size to 531cc @ 44hp with drum brakes to make the new model S500 convertible for the Japanese domestic market.
