2001 INFINITI QX4 review: Our expert's take


The verdict:

Versus the competiton:

As concerned Ford Explorer owners search for replacement tires, I found myself helping friends clean out a garage full of old car parts.

The reason car enthusiasts hord parts is so that when something breaks, the collector will have a spare on hand. Although these friends (aka the troublemakers) do have extra tires, some of which I hauled, they don’t have any extra Explorer tires. This is despite owning an Explorer.

Of course, after an afternoon of hauling dusty old boxes full of enigmatic scraps of rubber and metal, it was comforting to climb into the cushy luxury of Infiniti’s newly-reworked QX4 sport utility vehicle. This vehicle was way too nice to haul dusty old car parts.

The basic chassis is carried over from last year, as is most of the bodywork. But the grille and bumpers have been reworked. The most notable change is the high-intensity discharge Xenon headlamps up front. But this subtle change shouldn’t hide the bigger change underneath.

For 2001, Infiniti ups the power ante with an all-new 3.5-liter double-overhead-cam V-6, good for 240 horsepower and 265 foot-pounds of torque. This is a huge improvement over the 3.3-liter single-overhead-cam 170-horsepower mill that previously resided under the hood. Power is effortless and comes on strong from low in the rev range. It comes on smooth, with a solid exhaust note to remind you that you’re riding in a truck. But it’s not objectionable.

Power is fed through a four-speed automatic transmission to an all-wheel-drive system. The system is derived from the all-wheel-drive system used in Nissan’s Skyline sport coupe. It works invisibly with a simple twist of a dash-mounted switch, delivering up to 50 percent of the vehicle’s torque to the front wheels. A low range is included for low-traction situations. For the first time, a two-wheel-drive version is available.

Handling is quite adept for an SUV. This was always a QX4 strong suit, but the added power makes it more apparent. There’s an excellent balance between a comfortable ride and capable handling. Body lean is minimal, and there’s little front-end dive when braking. There’s some tire noise, but otherwise, the car is quiet. This is one SUV that has terrific on-road manners.

Overall, this is one the best handling SUVs I’ve driven in a while.

The interior sees some change, as well as the exterior.

Infiniti warms up the interior with generous doses of leather and imitation birds-eye maple. With a new analog clock at the top center of the dash, the interior does have a more opulent feel. The leather is of a better quality than previous samples.

The dash has easy to read gauges, although as is typical these days, information is limited to fuel and temperature. The test vehicle has the optional GPS system installed, which mired the otherwise ergonomically-correct interior.

Like all GPS systems, this one was distracting. The visual presentation is crudely executed, again, common to most systems o f this ilk. Uncommonly, this map was presented in a 3-D grid and didn’t seem very accurate. Worse, one has to use the GPS screen to adjust the climate control. Skip this option.

The center console had plenty of space for beverages. The storage bin had loads of space. A console and outside temperature gauge is mounted just above the rear-view mirror. Heated seats, auto up/down windows, seat position memory were all included. Despite the pretense of luxury, there were a couple items missing that are common in luxury vehicles. There’s no auto-dimming rearview mirror, rear seat climate controls or mini-computer to gauge fuel economy and other miscellaneous info.

The low-mounted front seats proved comfortable, although long-legged drivers will find leg room on the short side. Raising the power-activated seats doesn’t help, for head room is tight. It’s even worse in the rear seat. I didn’t fit. This cabin seems very tight for the size and mission of the vehicle.

Cargo room is ge ous and like any SUV the rear seats fold flat to provide 85 cubic feet of space. The CD changer is located in the cargo area behind a door. A piece of velcro keeps it from flopping about. However, there’s no provision for the CD cases, which must be carried elsewhere.

Fuel economy was about the norm for an SUV, 16.5 mpg in mostly city/suburban driving. Inifiniti recommends using premium fuel.

Yes, this quiet capable SUV was way too nice to haul old Packard parts. But it was nice enough to haul my aching body home to rest up for next week.

There’s still half a garage to empty.

Bought it for a VERY low price.

I bought mine for $400 but did three times that amount of work on it. They are prone to having the Nissan Death Wobble ($900+ fix) always check by bringing it to a mechanic and ask them to check the stabilizer bars. After getting all the problems fixed tho, smooth ride, very reliable.


311,541 miles and counting!!!

Simply the most reliable car I've ever owned. I am the 2nd owner and bought this car in 2011 at 134,000 , give or take. My work has me commuting all over, and in a mere 9 years I have racked up another 180,000 miles. In the past, I would consider selling a car approaching that 200,000 milestone. But this baby is still running as strong as when i first purchased her. Nope...can't let her go now. She's been too good to me. If you maintain this car, (I run a 5w30 synthetic blend w/mid-grade fuel), it will run forever. I'm looking forward to the next 300,000...happy anniversary, baby!


Never let me down but that factory stereo is a tur

Yes this infiniti has met all of my needs and then some , plenty of power , i live in new england and 4wd is a must and the 4wd is so simple no hubs to lock and HI-LO never fails knock on wood and goes through any amount of snow .. Only complaint is the 1st start of the day you have to keep the foot on the throttle until it warms up , must be a bad TPS but I can live with it , also love the fact its a timing chain engine not belt and engine is extremely quiet and smooth as silk . I would strongly recommend purchasing one
