The Q45 was the car that launched Infiniti when it went on sale in August 1989 as a 1990 model, powered by a 278-hp 4.5-liter DOHC V8 (VH45DE) and competing directly with the Lexus LS 400 and Acura Legend. Its early advertising was famously abstract — rocks and rivers rather than the car itself — which became a marketing cautionary tale.
Three generations spanned its life: the first (1990–1996) was developed specifically for Infiniti and based on the Nissan President platform; the second (1997–2001) was a more conservative rebadge of the Nissan Cima on the Y33 platform; the third (2002–2006) was a restyled car that continued until Infiniti retired the nameplate in favor of the Nissan Fuga-based M sedan.
