The Infiniti Q45 was Nissan’s bold flagship luxury sedan, launched in 1989 to challenge established European prestige cars with a distinctly Japanese blend of refinement, engineering and performance. Powered by the smooth VH45DE 4.5 litre V8, the early Q45 delivered strong, effortless acceleration, rear wheel drive balance and advanced features that felt genuinely futuristic for the era. Depending on model and market, highlights included active suspension, four wheel steering, leather trim, premium audio and a cabin designed around quiet, long distance comfort. For owners maintaining or upgrading an Infiniti Q45, Automotive Superstore can help with essential service parts, braking components, suspension items, filters, fluids, lighting, detailing products and accessories to keep this rare luxury sedan feeling special.

An interesting piece of Q45 trivia is that the original advertising avoided showing the car itself, focusing instead on abstract images such as rocks and trees to communicate serenity and craftsmanship. While memorable, the campaign confused many buyers, making early Q45s something of an enthusiast secret rather than a mainstream luxury success. Today, that understated image adds to its appeal. The Q45 represents a fascinating moment when Japanese manufacturers were proving they could build world class luxury cars with serious performance credentials. Its V8 engine is especially respected, with related Nissan motorsport engineering helping cement the VH family’s reputation for strength. For collectors and daily drivers alike, the Q45 rewards careful maintenance, quality replacement parts and attention to suspension, cooling and braking systems.
