Like people, sport utility vehicles operate at their best when they stick to the straight and narrow. That’s especially true for big guys like the 2019 Infiniti QX80.

The reason is that full-size SUVs often are the machines of choice for families that eschew minivans but need space and towing capability for vacation jaunts. For that, the QX80 has solid qualifications. Given its size — 17.5 feet long and 6 feet 4 inches tall — it is powerful, quiet and easy to drive.

However, it has a tendency to wander in straight-line freeway driving, requiring frequent small steering corrections to keep tracking true. That’s not much of a problem on short trips but can contribute to driver fatigue over long distances.

Though its gender has not been established, the QX80 is celebrating its quinceañerawith this model, which had its debut in 2004 as the QX56. It tops the SUV lineup at Infiniti, the luxury division of Japan’s Nissan.

Despite an age that matches a girl’s 15thbirthday in Spanish-speaking countries, the QX80 has something of the feel of a senior citizen. It uses a classic body-on-frame construction, not unlike that of all the big pickup trucks on the market. And though it is equipped with a modern suspension system and a full suite of computerized safety innovations, it has something of an old-fashioned feel.

Some clues: The parking brake is one of those step-on affairs, where you stomp on a pedal with your left foot, instead of modern electronic controls. Second-row captain’s chairs on the tested seven-passenger Limited models do not have fore-and-aft adjustments to improve third-row knee and foot space, and the seatbacks recline only a few inches.

The split third-row seats fold with the touch of button but you have to hold your finger on it until it gets where it’s going. No one-touch control here. And the seats don’t fold flat, leaving a bunny-hill incline to welcome your extra cargo.

Then there’s the matter of getting back to the third row. Though the second-row captain’s chairs on the tested Limited model flip up and out of the way, scrambling into the third-row seats should be reserved for teenagers and younger kids. Also, they should be skinny because there are three seatbelts back there.

There’s just 17 cubic feet of space behind the third row of seats, although the QX80 can carry a payload of 1,460 lbs and it can tow a trailer of up to 8,500 lbs.

One old-fashioned component is welcome. In an era when small turbocharged four-cylinder engines are taking over even in big pickup trucks, the QX80 soldiers on with a solid, burbling V8 engine. It delivers 400 hp and 413 lb-ft of torque from 5.6-liters of displacement.

It makes the driving experience feel effortless. Need to change a lane quickly without neck-snapping your passengers, simply step a bit forcefully on the loud pedal and crank the steering wheel. The power surges instantly and smoothly, with no hint of dreaded turbo lag.

The downside, of course, hits the purse or wallet. With nearly three tons of metal and other ingredients to move, the QX80 guzzled premium fuel like an elephant in a pool of spring water. City/highway/combined consumption is rated by the EPA at 13/19/15 mpg.

That likely won’t matter much to the buyers who can afford the tested Limited model. Though you can find a QX80 with a base price of $66,395, the Limited came with a $91,095 base price. With a few minor options, the bottom-line sticker came to $91,950.

No surprise, that amount of money brings a load of equipment, including the seven-speed automatic transmission with manual-shift control, all-wheel drive, self-leveling rear suspension system, 22-inch aluminum alloy wheels, leather upholstery, tri-zone automatic climate control, motorized steering wheel adjustments, adaptive LED lighting, Bose audio with navigation and SXM satellite radio, and adaptive cruise control.

Full safety equipment includes pre-collision intervention with pedestrian detection forward and back, lane departure prevention, blind-spot warning, active head restraints, electronic brake force distribution and pre-crash adjustable front seat belts.

Styling, of course, always lies in the eyes of the beholders. Suffice to say that the QX80 presents an imposing, almost intimidating appearance to other, smaller vehicles on the highways. It is, however, up against a host of similar three-row SUVs and even crossovers that span the utility segment from middle-class to luxury.
