Unlike the first rendition of the Q, this one is traditional down to every last nut and bolt. Like Acura and its new 3.5RL, the Q takes its cues from the immensely successful Lexus LS400 rather than from builders across the Atlantic. It seems these days that if people want European styling they prefer to get it from European makers like BMW and Mercedes-Benz. Thus, the sporting nature of the first-generation Q45 has been engineered out of the car in favor of a quiet, isolated ride worthy of dignified heads of state.

Although this version of the Q45 is slightly shorter than the previous model, it actually offers more interior space; most noticeable to rear seat passengers. As one would expect in a flagship sedan from a luxury marque, the Q abounds with sumptuous features such as power leather seats, wood accents, premium Bose sound system, driver's seat memory, automatic climate control, power sunroof and power tilt/telescoping steering wheel. Gone, however, is the beautiful dashboard timepiece that adorned the dashboard of the first generation Q45, in the new model it is replaced by a more traditional digital clock. Also noticeably missing are dual zone temperature controls, central locking and retained accessory power; standard fare on sedans that cost thousands less than the Q45.

The 1997 Q45 replaces the 4.5-liter V8 engine for a less powerful 4.1-liter V8. Despite this, straight-line acceleration is not much diminished due to the new car's lower curb weight. The new Q is also sprung more softly than the previous model, which allows the car to soak up those nasty expansion joints and pot holes, but sacrifices some of the previous model's cornering ability. Overall, though, the Q45 offers a nice ride that is perfect for cross-country cruising.

Lest we sound like grumpy old men resistant to change, let us assure you that we like this car. We just think that we, and undoubtedly some of you, will miss the big, aggressive power of the former model. Nonetheless, if you are in the market for a large luxurious sedan, and are unwilling to fight the gremlins that habitually inhabit many of Cadillac's luxo-cruisers, you owe it to yourself to test drive a Q45.

1998 Highlights

The Q45 gets front seatbelt pre-tensioners. No other changes for Infiniti's flagship.

Awesome Car! Real Sleeper!!

Steve McGee,03/26/2016

Loved this car from the first time I got behind the wheel! Only paid $2500 three years ago (122K miles). Just turned over 167K....power steering pump, alternator, and two ignition coils have been the only replacements/repairs over those 45000 miles. Very sweet ride!

Forced Retirement

daross1,12/09/2013

Just had to retire my 1998 Q45 due to being rearended and totalled. Car had 232000 on it and was overall very reliable. Not a single problem until 155,000 Miles. Fuel Injectors, Coils, and just age were starting to cause more problems, but I think it would have gone to 300,000 if not for accident. Overall, fun to drive, reliable, and excellent value as cost to own is only a little

There's not a better car I've owned...

hypocorism,11/11/2014

Bought a 98' for cheap at 72K. Needed a bit, but after valve cover gaskets, belts, battery, oil, air filter, it was ready to go. It sat for years under previous ownership. When I purchased, it had the original belts on it still. A testament to Nissan/Infiniti build quality. It doesn't do bad MPG-wise either. It goes when you need it to. Despite the size, it goes around corners, and stops

Flash of the QT

Fun, smooth and powerful. Handles great for a big powerful rear drive car. 125 mph, no problem.

Should I lease or buy a 1998 INFINITI Q45?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
