Glorias were sold at dealerships that were affiliated with the Prince company; when Nissan assumed operations, Glorias were sold at dealerships that sold the Nissan Skyline.
According to the article found in Japanese Wikipedia, the Gloria got its name as a tribute when the first series BSLI sedan was presented to the then Crown Prince Akihito, the future Emperor of Japan, and Princess Michiko as a anniversary gift after one year of marriage. The Prince Automotive Industry was the official vehicle supplier to the Imperial Household at that time, previously known as Fuji Precision Technology. It was inspired by the Latin word "Glory".
The Prince Automobile Manufacturers, previously known as Fuji Precision Industry, released a modification of their Prince Skyline with a more luxurious approach, and modified exterior sheet metal, at the All Japan Automobile Show, after the Tokyo Motor Show and the Skyline 1900 exhibition, on October 1958. February 1959 the Gloria was released with the 1.9 L OHV 4 cylinder engine.
In April 1959, the Crown Prince and future Emperor of Japan was presented with the first Gloria.
For 1961 and 1962, Prince modified the Skyline with a larger 1.9 L engine and more luxury features. The GB-30 straight-4 produced 80hp (60kW).
The suspension used double wishbone and coil springs in the front, and De Dion setup in the back.
Later that same year, Prince introduced the S40 Gloria. It was the first 6-cylinder Prince, offering an updated straight-4, the 94hp (70kW) 1.9L G-2, or a straight-6 variant known as S41 Gloria 6. This new engine, called the G-7, produced 106hp (79kW) with a new SOHC head. The Gloria had an independent suspension in front and a de Dion tube in the back.
A prototype of the Second Generation Gloria had many design similarities to the Chevrolet Corvair, so the car was completely redesigned.
On October 1962 at the 9th All-Japan Auto show, the 2.5 L engine was presented.
