Not only was the S50-1 a change in direction in it's overall concept, it also represented a complete change is style as well. The ALSI Skyline before it had the appearence of being something like a Peugeot, but with a rather heavy American influence, it's frontal design and finned rear end had more in common with a mid-1950s Chevrolet BelAir than anything else. The new S50-1 looked nothing like it. If you had to draw a comparison with anything you would probably say it looked more Italian, something akin to a Fiat 1300. The Italian influence comes as no surprise, in 1962 Prince used the Italian designer Giovanni Michelotti to design their BLRA-3 Skyline Sport couple. Whilst there is no suggestion anywhere that Michelotti had any input into the S50-1 design, it is obvious the Prince designers has a long hard look at the way he worked. What the Prince designers came up with was a very pretty, and thoroughly modern little car.

The Skyline sedan was available in two versions, the S50S-1 standard model, and the S50D-1 Deluxe model. The Deluxe had a cast alloy grille, which featured 5 wide vertical bars with a series of narrow vertical bars inbetween them. It had stainless steel side strips that ran the full lenght of the car, and had badges mounted at the back under the strip that said "Skyline 1500 Deluxe". The standard version had a pressed steel grille that featured 8 horizontal bars, though rather confusingly the S50E-1 standard model for export was fitted with the Deluxe grille in many non-Asian markets. The standard model had stainless steel side strips that went from the back of the car through to halfway along the front doors. It's badges were mounted to the front doors and said "Skyline 1500". Deluxe cars has robber capped over riders on the bumpers, while the standard did not. Both cars featured large round stop lights, a design hallmark that would be used on most Prince, Datsun and Nissan Skyline models right through to today's R35 GT-R. Both models have a "PRINCE" badge on the bootlid.

The previous Skyline had used an 1862cc engine, but in line with the S50-1's move into a less expensive catagory it reverted back to using a 1484cc engine, the same size as the original Skyline. This engine was pretty much the same as the one first used in the ALSI-2 Skyline, which was the FG4A-40, which was also cryptically called the GA4, but even more cryptically in the S50-1 it was refered to as the G-1. It continued to produce 70hp. This was mated to a 3 speed column change gearbox, though in 1965 a 4 speed floor change model was introduced as well.

A wagon version went into production at the end of 1964. The wagon was called the W50A-1. It had pretty much the same equipment level as the Deluxe sedan. Like the Deluxe sedan, it had side strips that ran the full length of the car. It's badges, mounted on the front guards, said "Skyline 1500 Estate". Export versions of this vehicle were called the W50ADE-1. There was also a van version of the wagon called the V51-1, which was marketed as a commercial vehicle. This was the same 5 door body as the W50A-1 Estate, but it had a trim and equipment level similar to the standard sedan. It had the side strips that went from the rear of the vehicle through to halfway along the front doors. The badges are located on the front doors. It also had bars inside the side rear windows to protect the glass from being damaged by cargo being moved in the back. This commercial vehicle version was badged as the Prince Skyway. An export version of this vehicle was available without the cargo bars in the back, and this was the W50AE-1. This export only model was badged as a Skyline and not a Skyway.
