The S500 was the first production car from Honda, released in 1963, following the T360 truck into production by four months. It was a larger displacement variant of the S360 roadster which, though developed for sale in 1962, was never produced.
Like the S360, the S500 used a high-tech engine developed from Honda's motorcycle expertise. It was a dual overhead camstraight-4 with four carburettors and a 9500 rpm redline. Originally intended to displace 492 cc, the production version was 531 cc and produced 44 hp at 8000 rpm.
