Eighth generation (Y31; 1987)
Most of the information in this article was translated from the Nissan Gloria article on Japanese Wikipedia at ja:日産・グロリア.
The Y31 sedan was introduced in 1987. The Y30 hardtop was replaced by the succeeding Y32, and the Y30 Wagon/Van version was not replaced. After this generation, Glorias were only available to private customers in four-door hardtop guise. Engines available continue to be the newly developed VG series engine as a result of Project 901, with the VG20DET adding DOHC, another first for Nissan. June 1987 saw a special edition Gloria intended for parade usage, removing the roof structure from the hardtop body style. "Super Sonic Suspension" was no longer offered and instead the MacPherson struts were optionally installed with internal air chambers combined with trailing lower control arms, while the standard suspension consisted of MacPherson struts for the front wheels, and coil springs and shock absorbers for the rear suspension; cars thus equipped carry an "A" in their chassis code (PAY31 rather than PY31). The four-speed automatic transmission is now computer controlled for smoother shifts. The transmission now exclusively uses a floor-mounted gear shifter, and a five-speed manual transmission was still available. The rear suspension was upgraded to multi-link independent setup. Trim levels are standard, Custom, Super Custom, Classic, Classic SV, Gran Turismo, and Brougham VIP. There was also a long wheelbase model built by Autech called the Royal Limousine. The Gran Turismo received more sport-oriented styling, adding a youthful appearance, which found new, younger, buyers. The sporty GranTurismo SV version had short bumpers with a body kit, and was powered by the turbo twin cam VG20DET engine. The sedan version of the Y31 was facelifted at the launch of the Y32; it was kept in production for professional use and as a more traditional, lower cost alternative to the hardtop-only succeeding generations. The Gloria is mechanically related to the Crew, although the former is larger.
The Gloria competed for buyers with related Nissan vehicles that shared platforms used for the Gloria, specifically, the Nissan Cima, Nissan Leopard and the Nissan Cedric, as well as other sport-oriented vehicles, such as the Nissan Cefiro, Nissan Skyline and Nissan Laurel. The Gloria Y31 can be distinguished from its sibling, the Cedric Y31 by the taillights.
The 4-speed automatic transmission is now computer controlled for smoother shifts. The transmission now exclusively uses a floor mounted gear shifter, and a 5-speed manual transmission is still available. The rear suspension was upgraded to multi-link independent setup. Trim levels start with the VIP Brougham, Gran Tourismo, Classic SV, Classic and Super Custom. The Gran Turismo received more sport-oriented styling, adding a youthful appearance, which found new, younger, buyers. To enhance rear passenger comfort and convenience, the four-door hardtop front driver and passenger seat belt shoulder strap was connected at the top to the ceiling, however, the upper portion could be detached, with the shoulder strap emerging from the side door support, resting on the driver's and passenger's shoulder. This provided rear passengers an unobstructed view from the rear seat without the seat belt hanging from the ceiling when the windows were retracted. The upper part would then swing up to the ceiling and could be fastened into place.
In June 1998 the Gloria sedan (still sold for either private or professional uses) was updated. Equipment levels were improved, now featuring standard double airbags up front (private cars only), a redesigned dashboard and interior for private cars and higher-end professional models, and other minor changes such as replacing the conventional antenna at the rear with one integrated into the rear windshield.[12] The facelifted version of the Y31 Gloria was discontinued in July 1999 and merged into the Cedric Sedan lineup, which continued to be produced until 2014 for taxi sales.[13][14]
Professional use Gloria sedans received lower powered engines, typically powered by LPG or (less popularly) diesel engines. Lower end models received the four-cylinder NA20P while better equipped versions like the Classic, Classic SV, and Brougham used the six-cylinder RB20P. The NA20P produces 82 PS; power increased to 85 PS at the time of the June 1998 updates.[12] Autech also offered an LPG-powered version of the VG20 engine (called the VG20LPG; when later built officially by Nissan, this engine became the VG20P), only in Brougham trim with a four-speed automatic and intended for police or special purpose uses.[15]
