1998 Infiniti Q45 Review

One of the better values available in the luxury sedan market.

Reviewed by Automotive on


The 1998 Infiniti Q45 marks the flagship model for this prestigious auto manufacturer. The Q45 has style, power, and luxury built straight into it. The Q45 offers almost no optional features because almost anything a driver can think of comes standard. Surprisingly, given the quantity of built-in features and equipment, the Infiniti Q45 carries a rather modest price tag. It still costs a lot, as drivers should expect for anything in the near-luxury market, but few vehicles offer the same level of equipment for the same price. In many cases, other vehicles might beat the Q45 on base price but become significantly more expensive due to the need for optional equipment.

The Infiniti Q45 comes in two different models. The base model is a powerful, well-equipped vehicle, no matter what optional equipment drivers add. Unlike many other models, the base Q45 does not skimp on features to reduce the price tag. The Infiniti Q45 Touring adds few additional amenities. Instead, the main difference to the Q45 Touring concerns the addition of a few extra features, like a sport suspension, to augment performance.

The Range

Body Styles: sedan
Engines: 4.1-liter eight-cylinder
Transmissions: five-speed manual, five-speed automatic
Models: Infiniti Q45, Infiniti Q45 Touring

What's New

The 1998 Infiniti Q45 replaces the 4.5-liter, eight-cylinder engine with a 4.1-liter, eight-cylinder engine. Front-seat pre tensioners also come standard.


Measuring in at 199.6 inches long, the Infiniti Q45 makes a fairly large sedan. However, compared to many near-luxury vehicles, the Q45 seems like an average size. The 1998 Infiniti Q45 has the slightly angular, conservative design common to all Infiniti models; it looks stylish and distinctive. The Q45 get immediately recognized as a luxury vehicle. Standard equipment includes keyless entry, lighted entry, an anti-theft alarm system, a power moonroof, a power antenna, auto-dimming mirrors, power windows, power mirrors, and power locks.


The 1998 Infiniti Q45, even with the base model, offers a wide range of luxury amenities. Leather seating, cruise control, power seats, a leather-trimmed tilt steering wheel, air-conditioning, automatic climate control, Bose audio, an AM/FM radio, a cassette player, and a CD player comprise the standard equipment for both models. The Q45 Touring also features standard leather trim. Heated seats, a CD changer, and an Infiniti communicator provide additional options.

Performance & Handling

The Infiniti Q45 offers amazing performance, even compared to the highly competitive near-luxury sedan market. The 4.1-liter, eight-cylinder engine delivers 266 horsepower, which allows the Q45 to accelerate quickly and reach a high top speed. The 1998 Infiniti Q45 has more power under its hood than some trucks and sport utility vehicles. The handling feels excellent and the Infiniti Q45 even handles well in slippery conditions.


Dual front airbags, front side airbags, four-wheel anti-lock brakes, and traction control come standard on all 1998 Infiniti Q45 models.
