2005 Infiniti Q45 Review

The Infiniti Q45 features new styling and more luxury equipment for 2005. It looks more aggressive than before, with new front and rear fascia, a restyled hood and grille, a new headlight design with integrated fog lights, a restyled rear deck, new LED tail lights, and new chrome trim.

Everything about the Q45 is smooth and easy. It's balanced well for driving on twisting roads and it's very stable at high speeds. Yet the ride is smooth, even on bumpy roads. Its powerful V8 engine delivers excellent performance and makes a wonderful growl. The Q45 uses rear-wheel drive, like a BMW or Mercedes-Benz, for better handling. The five-speed automatic transmission has been re-calibrated on 2005 models for smoother acceleration and more responsive downshifts. The active damping suspension, previously optional, is standard on all 2005 models.

Infiniti may not have the heritage of BMW or Mercedes, but it offers first-class appointments and craftsmanship. A DVD-based navigation system is now standard. A new system tightens the seatbelts during emergency braking, helping to optimize the position of the driver for emergency maneuvers and crash protection.

The Infiniti Q45 has presence, with styling that says big luxury. Grille, hood, and front and rear fascia are new for 2005, lending the Q45 a more assertive, if not downright aggressive, demeanor.

The headlights are new, with integrated fog lamps and larger bulbs for high beams. The headlamps incorporate a revised version of the Q45's trademark circle of seven xenon low beams that look like a Gatling gun. The aggressive appearance of the headlamps suggests the ability to turn night into day. Infiniti claims they are among the world's most powerful; its low beams are bright and have a dispersion pattern designed for long-range illumination in a narrow beam as well as wide-angle illumination in the foreground. The pattern of the low beams is designed to reduce glare to oncoming drivers by cutting the beam sharply on the left side. A switch on the dash allows the driver to adjust the height of the beams, a feature we liked.

Overall, the front view of the Q presents a handsome shape, a sweep, as if the lines were poured on. There's very little chrome. The wide-mouthed grille is fully but sparsely filled by four broad, horizontal slats with a bright Infiniti emblem in the center. Hungry-looking air intakes dominate the lower bumper.

In profile, the Q45's long wheelbase and relatively short overhangs suggest solidity and efficiency at the same time. Its drag coefficient is among the lowest of any production car we know, at just 0.30. The roof seems to have more rake when viewed from the rear.

The 2005 Q45 has a new rear bumper, deck lid, and LED taillights, the latter reminding us of the lights on the smaller G35, all accented by new fine-line chrome trim. The exterior modifications bring a new sense of power and athleticism to the Q, along with a stronger family resemblance to our other Infiniti performance vehicles.
