The Infiniti Q45 is a full-size luxury sedan manufactured and marketed by Nissan's Infiniti brand for model years 1989-2006, over three generations. The first generation Q45 (1989–1999) was based on the Nissan President; the second generation (1997–2000) and third generation (2002–2006) were based on Nissan's JDM Nissan Cima. Exports of the Q45 ended after MY 2006. First generation (G50; 1989–1996) The first generation Q45 came to market in 1989 as a 1990 model with a high-output 4.5 L V8 engine rated at and in North American trim. All Q45s included a VLSD (viscous limited-slip differential), as part of a multi-link suspension. At the time, Nissan was working on a program called the "901 Movement," with the aim of making Nissan's the best handling lineup in the industry. In Japan, it was marketed as the Nissan Infiniti Q45, and was exclusive to Nissan Prince Store locations, as its platform twin the President was exclusive to Nissan Motor Store locations. Equipment included a Bose sound system, leather interior, power adjustable front passenger seats with two position memory feature that also electrically adjusted the steering wheel, exterior mirrors, one-touch power windows, digital climate control, and keyless entry system. It was equipped with instrument lighting using a reverse effect of white light on the gauges with black numbers. Revisions in 1993 included 17:1 steering (except on the Q45t, which retained the original 15.1:1 ratio), lower ratio 1st and 2nd gears, and a dynamically smooth suspension, thicker glass, keyless remote, auto-dim rear-view mirror, dipping side view mirrors, revised transmission heat exchanger and external ATF filter, revised oval intake ports and revised disc injectors, fog lights and metal-backed camshaft timing chain guides. Infiniti offered the Q45 in three trim levels: base, Q45t, and Q45a. The Q45t and Q45a featured a multi-link suspension at both the front and rear wheels, and included a rear stabilizer bar (with the Q45a model being larger in diameter) and both models having a 1 mm smaller in diameter front sway bar, rear spoiler, BBS forged alloy wheels, 4-wheel steering. HICAS and the faster steering ratios was discontinued in the 1995 Q45t model and the Q45a model was not imported in 1996. In 1989 (as a 1990 model) a full "active suspension (FAS)" was introduced. It employed 10 sensors sending signals to microprocessor-controlled hydraulic actuators at each wheel. It was designed to reduce body roll, dive and pitch and was very similar
