The Honda S600 was launched in March 1964 as a roadster and a year later as a fastback coupé. It looked very similar to its predecessor the S500. Production lasted until 1966, during which period 11,284 convertibles and 1,800 coupés were made.
It was powered by a DOHC, water-cooled, four-cylinder inline engine with four Keihin carburettors, with a capacity of 606 cc. The engine produced 57 bhp at a high 8,500 rpm, and had a top speed of 90 mph – not surprising, with a weight for the roadster of only 1,576 lb (715 kg). Suspension was independent, with sealed roller chain drive to each rear wheel.
The S600 was the first Honda car to be mass-marketed. Initially offered only in right-hand drive, it was soon available in left-hand drive for export markets. It was succeeded by the S800.
