The Cima eventually replaced the venerable Nissan Cedric / Nissan Gloria as Nissan's premier sedan, just below the limosiune Nissan President, on which the current Cima is mechanically related.
With info from the article for the Nissan Cima in the Japanese Wikipedia:
Up until 1989, the Japanese tax bracket dictated a division point at the car being 4700mm long, 1700mm wide, with a 2 liter engine. Both the Nissan Cedric/Nissan Gloria and its archrival, the Toyota Crown were stretched to this very limit. When rumors came that Toyota was developing a larger, wider extension of the Crown, called the Crown Majesta Nissan acted hastily and could not get the wide version ready for the narrow version's launch in June 1987. The half-year gap in development, however, brought about many changes in design. This generation was manufactured as a 4 door hardtop, with no B-piller between the front and rear side glass windows.
The Y31 Cima is available with a 200 horsepower (149 kW) VG30DE or a 255 horsepower (190 kW) turbocharged VG30DET. The turbocharged version was especially popular, leading the media to coin the term "the Cima phenomenon". The Cedric Cima was sold at dealerships where the Nissan Laurel could be found in Japan, and the Gloria Cima was sold at Nissan dealerships that sold the Nissan Skyline. The Cima was available with an air suspension.
