1997 Infiniti QX4 Sport Utility Vehicle Review & Performance

all-new unitbody chassis--a major investment for Nissan--you'd expect considerable

commonality between Pathfinder and QX4, and that's exactly what you get.

This is not a bad thing. The new unitbody chassis is much stiffer than

the traditional pickup truck body-on-frame approach still used by most

sport-utility manufacturers, and should keep squeaks and rattles at bay

for much longer. It also provides a solid platform for anchoring suspension

components, which allows more latitude for tuning those components to deliver

optimal ride and handling.

The QX4 also shares the Pathfinder's 3.3-liter V6, and on this front

we'd say the commonality is just okay. Although this engine has good torque

characteristics, its 160 horsepower is modest for this class, particularly

in a vehicle as heavy as the QX4. At 4275 pounds, the QX4 is about 250

pounds heavier than the heaviest version of the Pathfinder, thanks to its

vast load of standard luxury features.

The V6 engine is mated to an electronically-controlled four-speed automatic

transmission, a point of difference from the Pathfinder, which comes with

a five-speed manual gearbox and offers the automatic as an option.

A bigger point of difference is the QX4's standard All-Mode 4WD system,

activated by a three-position switch. Similar in concept to the Explorer's

4-wheel drive, the All-Mode system can be set for rear-drive only, automatic

all-wheel drive that varies the front-rear torque split on a basis of available

traction and a locked mode that divides torque equally between the front

and rear so all the wheels churn equally. Unlike the Explorer, there's

also a low range 4WD, engaged by a separate transfer case shifter, for

max traction in really tough or gooey going.

The visible difference is as you see. There's a little bit of 21st century

in that bluff-bowed grillework, with its multiple air intakes, and plastic

cladding spiffs up the side panels.

Infiniti obviously doesn't want anyone to confuse the QX4 with the Pathfinder,

and we think there's not much danger of that happening.

posh, and that's exactly what you get in the QX4. Creamy leather, power

adjustability on almost everything that adjusts, plenty of woodgrain, excellent

audio, automatic climate control and a big center console with enough elbow

space for both front seaters to use without territorial squabbles.

The front bucket seats are as comfortable as they are attractive, and

the whole interior reflects a level of quality that's appropriate for this

brand name. Which is to say high indeed.

In fact, if it weren't for the high seating position, it would be easy

to think you'd just climbed into a luxury sedan, an impression that's reinforced

by the driving experience.

This is a sumptuous and pleasant place to be as the miles roll by--provided

you happen to be in one of the front seats. The rear seat is another story.

There's just barely enough space back there for adult-size people, or at

least for people with adult-size legs.

The Pathfinder's exterior dimensions expanded in its redesign, but its

rear seat legroom didn't, which is unusual considering the emphasis placed

on this commodity in other designs, such as the best-selling Ford Explorer.

Something else that didn't make total sense to us was the QX4's running

boards. The idea is to make it easier to deal with a sport-utility's higher

step-in, but once you've stepped up you find yourself ducking and bending

to climb in. But, it works nicely if you're short.

About the only redeeming virtue we can think of for these add-ons is

that they make it easier to get at stuff you've loaded onto the roof rack.

it is to ever venture off the pavement, a sport-utility axiom that's reflected

in the QX4's ride quality and handling. While there's enough muscle in

the springs and shocks to handle the possibility of off-road use, the tuning

is skewed in favor of keeping all the occupants comfy on paved roads, be

they smooth or be they gnarly.

We were impressed with the QX4's ability to smooth out small bumps and

potholes. It's very close to the kind of ride quality you'd associate with,

say, Infiniti's Q45 luxury sedan--firm, controlled and quiet. There's hardly

a trace of road noise filtering up through the suspension, and engine sounds

are generally subdued, at least until you put the pedal right to the floor.

Considering its imposing mass, the QX4 is surprisingly handy in quick

maneuvers, a function, perhaps, of its relatively low roofline and ride

height, which helps to keep the center of gravity low, at least by sport-utility

standards.

We liked the precise response of the power rack and pinion steering

system--another car-like attribute--while braking performance is better

than average for a vehicle in this size and weight class.

However, car-like acceleration isn't part of the deal here. The Pathfinder/

QX4 V6 is willing enough, but it's hitched up to too much mass to produce

zippy getaways. Yes, that's true of most sport-utilities, but even in this

deliberate world the QX4's straight ahead performance stacks up as only

average.

On the other hand, the sturdy V6 has decent low-end grunt, which is

what you want if you're trundling around out in the woods somewhere. And

even though the QX4 isn't really cut out for really tough terrain, it has

enough ground clearance--8.3 inches--to handle Forest Service trails and

the like. A skidplate under the rear differential--part of the QX4's standard

equipment--helps out for this kind of work, too.

It's also capable of towing a good-sized trailer, although we think

testing the 5000-pound upper limit would require patience.
