Infiniti Q45

One can arguably say that the introduction of luxury performance sedans such as the Q45 and its main competitor, the Lexus LS, had triggered the luxury car market into realizing that full-size, high-priced luxury sedans should provide better-than-average performance as well as provide luxurious amenities. The Infiniti Q45 was a full-size luxury car that served as the flagship of Nissan's Infiniti marquee until 2006. It is a rear wheel drive luxury sedan powered by a V8 engine. The original Infiniti Q45 was based on the Japanese-market Nissan President, but later generations were based on the lower-end Nissan Cima. The Q45 competed most directly with the Lexus LS, the BMW 7 Series and the Mercedes-Benz S-Class. The first Q45 came to market in 1989 as 1990 model. Car magazines and reviewers were awed by the Q45's performance such as a 0-60 mph acceleration time of 6.7 seconds, and its high-output 4.5 L V8 engine rated at 278 hp. At the time, its targeted competitors such as the Mercedes S-Class, the BMW 7 Series, the Jaguar XJ and the Cadillac Fleetwood had much bigger engines with horsepower ratings in the lower 200 hp range and 0-60 mph times at an average of 9-10 seconds. In terms of styling, the Infiniti Q45 was a distinctive vehicle. Infiniti attempted to redefine the modern luxury sedan by offering a car with rather demure amenities such as firm leather seats instead of cushy couch-like seats and no chrome or wood grain interior trim. Thicker glass, keyless remote, auto-dim rearview mirror, dipping side view mirrors, an improved transmission heat exchanger and external ATF filter, new oval intake ports and revised disc injectors, lower ratio 1st and 2nd gears, fog lights, and metal backed camshaft timing chain guides were added in 1994. That was one heck of an overhaul.
