Infiniti Q45
The Infiniti Q45 is a full-size luxury sedan (F-segment in Europe) that was marketed by the Infiniti division of Nissan from the 1990 to 2006 model years. The inaugural product line and flagship sedan of the brand, the Q45 competed directly against the Acura Legend and Lexus LS 400, as multiple Japanese automobile manufacturers began to establish dedicated luxury-vehicle brands in North America during the late 1980s. As with the Lexus LS, the Q45 also competed against the BMW 7-Series and Mercedes-Benz S-Class, matching them closely in size. Three generations of the model line were produced. The first generation (G50; 1990–1996) was developed specifically for Infiniti; a long-wheelbase version with Nissan President was developed from it. The second generation (Y33; 1997–2000) became a rebranded version of the Nissan Cima (a longer-wheelbase version of the Nissan Cedric/Gloria). The third and final generation (F50; 2002–2006) was again derived from the Cima, again sharing a platform with the President. After the 2006 model year, Infiniti discontinued the Q45 as it shifted its strategy towards higher-performance vehicles, with the Nissan Fuga-based Infiniti M becoming its new flagship sedan. In 2013, Infiniti revised its branding, with all of its cars adopting the Q from the Q45 (SUVs, becoming QX), with engine-displacement nomenclature replaced by a two-digit number relative to its place in the Infiniti model range. From 1989 to 2006, Nissan produced the Infiniti Q45 in its Kaminokawa, Tochigi facility.
