Toyota launched the first Corona on 1 July 1957 as a quick response to demand for a sub-1,000 cc passenger car. Kanto Auto Works designed and manufactured it with available S-engine, Crown running-gear and Master body components. The pragmatic parts-sharing program still produced a structural milestone: Toyota identifies the ST10 as its first passenger car with a monocoque body.
Look a little closer.
Toyota was developing a newer compact car and P engine, but its dealer network needed a small passenger car immediately. The ST10 used existing pieces and Kanto Auto Works' capacity to reach customers in 1957 rather than waiting for the PT10 program.
