In 1961 Fuji Precision Industries changed its name to Prince Motor Company (for the second time). Two years later, in September 1963, the S50 Skyline Deluxe (S50D-1) was launched, followed by the Skyline Standard (S50S-1) in April 1964. This was the second generation car, and became one of the more desirable cars in Japan. It was powered by the "G-1" engine, a 68 hp or version of the old GA-4. The S50 series were available with a three-speed column shift transmission, or a four-speed floor shift transmission from February 1965 (Deluxe only). A two-speed automatic option was added to the Deluxe in June 1966. The lower priced and equipped Standard model was added in April 1964; aiming at taxi operators and others it also lacked bumper overriders, making it 11 cm shorter. Three main models of the S50 were built: the S50-1 (1964–1966), the lightly facelifted S50-2 (1966–1967) and the S50-3 (1967–1968). These all used the same engine, with the later S57 receiving a more modern unit.
