In 1961 Fuji Precision Industries changed its name to Prince after the 1954 merger. Two years later, in September 1963, the S50 series was launched. Like its predecessor, it came in sedan and wagon bodystyles. 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 70 PS (51 kW) 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, either as a four-door sedan (S50) or a five-door wagon (W50). Three models of the S50 were built: the S50E (1963–1965), S50E-2 (1965–1966), and S50E-3 (1967). These three all used the same engine, with the later S57 receiving a more modern unit.
Externally, this generation was installed with rounded brake lights and integrated tail lights, with a centrally installed turn signal, similar in appearance to the Ford Galaxie of 1960. The significant appearance change from the previous generation seems to reflect a similar approach done by German company BMW in 1962, in deciding to build a small, affordable, performance coupe and sedan.
The S50 was sold in some markets with an A150 designation. The S50 was also sold as the A190D, which was equipped with a diesel engine.
In 1966, Nissan and Prince merged and the S50 also appeared with Nissan Prince Skyline badging. This model lasted in production through 1967. In 1967, the S50E-3 was introduced. It was sold as Prince Skyline, Prince A150, PMC A150, or Nissan A150, depending on the market.
All "Prince" dealership locations were added to the existing Nissan/Datsun Japanese dealerships, while retaining the Prince name to become Nissan Prince Store.
Prince created a racing GT Skyline in May 1964. It was based on the S54 and used the larger six-cylinder G-7 engine from the Gloria S41, though the car needed a 200 mm (8 in) extension to the wheelbase (all forward of the cowl/firewall) to provide space in the engine bay for the lankier in-line six. When it entered the second Japanese Grand prix they hoped to win the GT-II class. Competitive against the Porsche 904, the Skyline managed second through to sixth places.
Largely due to the success of the race vehicle, the Prince Skyline 2000GT (also called GT-A, GT-B, S54A and S54B) was released to the Japanese market. There were two versions produced:
- S54A – 1,988 cc G-7 single-carb I6, 105 PS (77 kW)
- S54B – 1,988 cc G-7 triple-carb I6, 125 PS (92 kW) at 5,600 rpm
The B model featured three Weber 40DCOE-18 carburetors, a limited slip differential, five-speed close ratio manual transmission, and power brakes. Both the B and A used front disc brakes with dual pistons and alloy finned drums in the rear.
The S50 Skyline was updated to become the S57 in late 1966, for the 1967 model year. It used a new engine of Prince's (designed before the merger with Nissan), the OHC 1.5 L (1,487 cc) G15. At 88 hp (66 kW), it was the most-powerful engine in the Japanese 1,500 cc class.
