Nissan President - President HG50

In October 1989 a new Nissan President, designated JHG50, debuted during the Tokyo Motor Show, with sales beginning a year later. Concurrently, a short-wheelbase version of the chassis debuted in the USA as Infiniti Q45 or Nissan Q45 in Japan, with a different front and rear end. This complete reworking of the President was the result of the introduction of the Lexus LS January 1989 and the Honda Legend in 1985. Major focus was being directed to large luxury sedans, and Nissan decided to follow the lead of Honda and Toyota and give the President a long overdue revisement. Both the President and the Q45 shared the new 4.5 litre VH45DE V8 engine. In 1993, a short-wheelbase version similar to the Infiniti joined the lineup, badged as President JS. At the same time, Nissan's special vehicles subsidiary Autech developed a Royal Limousine model with split passenger compartment. The Royal was created as a possible replacement for the two 1966 Nissan Prince Royals used by the Imperial Household Agency, but were not accepted.

An interesting feature also debuted in 1993 — an airbag for the left-hand side (curbside) rear seat passenger. In 1994, along with a minor facelift, Nissan revived the Sovereign trim level (previously available for 250 Presidents) for the long-wheelbase model. Another minor facelift occurred in 1998 (designated PHG50). At the same time, the previous Infiniti Q45 was replaced by a model based on a smaller (yet still large) Nissan Cima, which was also fitted with the rear passenger airbag option in Japan. The PHG50 continued in production till 2002 with the arrival of the new F50 chassis.
