position the President as a top-level luxury limousine, with high levels of standard equipment, including Connolly Leather or wool and silk upholstery. 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. 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. 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 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.

The PHG50 continued in production until 2002 with the arrival of the new F50 chassis. Fourth generation (PGF50; 2003) The third generation was introduced in October 2003, based on the F50 Nissan Cima which had debuted in 2001, being also powered by the same 4.5-litre VK45DE V8 engine. It retained its top position as the flagship limousine at the reorganized Japanese Nissan dealerships called Nissan Blue Stage. Two versions were available, both badged Sovereign, with either five-passenger or four-passenger seating configuration. This model remained Nissan's traditional competitor to the Toyota limousines the Toyota Century and Toyota Celsior, and it competed for customers for three years with the all-new Mitsubishi Dignity as the top level flagship, however Mitsubishi chose to use front wheel drive. The four-passenger version is considerably more expensive and features lavish equipment, including a Bose sound system and a host of other electronic devices controlled from a panel in the rear central armrest, as well as a "relaxing seat"—a feature allowing the left front passenger seat to be tilted forward, allowing
