In October 1989, the third-generation President, designated
JHG50, debuted at the
Tokyo Motor Show, with sales beginning a year later. Concurrently, a short-wheelbase version of the chassis PHG50 debuted in the United States as
Infiniti Q45 or Nissan Infiniti Q45 in Japan, without a grille as a visual difference to the 1989
Lexus LS and the 1985
Acura Legend. As a result of
Project 901, there was a renewed emphasis on positioning the President as a senior corporate luxury limousine with high levels of standard equipment, including
Connolly Leather or a combined wool and silk blend upholstery. Extras included a diamond inlay on the key, gold plate hood ornament and rear badging, and ultrasound massage in the rear seats. Vehicles could be optionally equipped with
Full-Active Suspension (JHG50 or PHG50) or conventional coil suspension (JG50 or PG50) while a
multi-link suspension was used at all four wheels, similar to the
Nissan Laurel (C33). This time the vehicle adopted many European styling cues, with its front now resembling the contemporary
Jaguar XJ. Unlike the previous, hand-made generations, this was the first President built on an assembly line. The new hood ornament was a stylized military headdress for ceremonial duties, called a
feather bonnet or a
busby. Innovative technological features included a world-first feature that debuted in 1993: SRS
airbag for the left-hand side (curbside) rear seat passenger. Both the President and the Q45 shared the new 4.5-litre
VH45DE V8 engine, although the President's engine was tuned down by ten horsepower to to avoid a too-sporting sound. In 1993, a short-wheelbase version similar to the Q45 joined the lineup, badged as
President JS positioned for personal ownership, and marketed as an alternative to the Cima, Cedric and Gloria. The President JS and the Nissan Infiniti Q45, exclusive to
Nissan Prince Store locations, discontinued in October 1997. Nissan's special vehicles subsidiary
Autech developed a
Royal Limousine model with a split passenger compartment for 1993. The Royal was created as a possible replacement for the four 1966
Nissan Prince Royals used by the
Imperial Household Agency for the
Coronation Ceremony, or
Shukuga Onretsu no Gi of
Akihito 12 November 1990, but were not accepted. 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 that didn't share a joint appearance. It was now called the
Nissan Cima and was also fitted with Japan's rear passenger airbag option. The PHG50 continued production until 2002 when the new F50 chassis was introduced. The combination wool-silk blend upholstery was replaced with a
jacquard moquette upholstery. In 1996, Autech introduced the "Relax Seat" feature and no longer offered the rear passenger airbag, replacing it with a side curtain airbag for both sides of the vehicle. Relax Seat allowed the front passenger seat to fold flat and slide forward, giving the rear passenger more legroom and the ability to extend and recline the seat. The model year 1999 introduced a revised front grille, integrated fog lights,
xenon headlights, and an upgrade to the audio-visual system, which also introduced a navigational system called
Compass Link. A monitor for the rear passengers was integrated into the audio-visual system, which was added on top of the rear edge of the front seat center console and concealed behind a flip-down door. == Fourth generation (2003–2010) ==
