2015 infiniti qx70s rwd review

Fifteen years ago, buying a practical luxury car to replace a Honda Accord meant going down to your BMW, Mercedes, Lexus, or occasionally, Audi showroom and coming back with a 5-Series, E-Class, GS, or if you were particularly brave, an A6. All these brands except Audi had SUVs at the time though, but they were hardly replacements for a midsize luxury sport sedan. The Mercedes ML handled like a truck while the RX300 wasn’t exactly intended for the sport sedan driver, something emphasized by the number of moms and AARP members who bought them at the time. Meanwhile, my dad test drove an X5 and 5-Series back to back and promptly bought a 530i.

But no one fifteen years ago would have considered Infiniti, whose only rear-drive sedan was the full-size Q45, which no one bought. A few years later, Infiniti went through a product renaissance, bringing out the Infiniti G35 (which many people bought), the M (the one based on the JDM Nissan Gloria few people bought), and an updated Q45 (which even fewer people bought). In 2003, they also brought out a sporty crossover – the FX. It was meant to compete with the X5, Porsche Cayenne, and XC90, but the FX was dramatically better on-road than off-road compared to most of its competitors. The FX, despite being smaller and not capable of tackling off-road trails, became a sales success for Infiniti.

And that success influenced its competition. The Cayenne became less off-road oriented, losing its dedicated two-range transfer case and getting much more rounded styling. BMW ended up creating the X6 from the X5. Acura joined the fray with the ZDX. Mercedes is finally entering the “crossover-coupe” market with the GLE Coupe.

Meanwhile, Infiniti now calls the FX the QX70 as part of Infiniti’s new naming system. It was last redesigned in 2008, around the time the X6 was released. The V8 is no longer available. Instead of the rounded trapezoid grille, the grille is now shaped like a wide rounded hourglass with a massive Infiniti emblem in the center.

First off, I cannot complain about the QX70’s performance, especially with the $3,550 Sport Package. Though the active rear steering and continuous damping control features that used to be part of the sport package are gone for 2015, the QX70 handled like any other sport package-equipped midsize luxury sedan. Driving it on the country roads around my house, the QX70 stuck to the road in corners at speeds where most SUVs would begin squealing their tires largely thanks to its black-colored 21-inch Enkei wheels. The 3.7-liter V6 had plenty of power handy while the seven-speed transmission was always selecting the right gear during my period of spirited driving.

The sport package also added to the visual effects of the QX70 with the aforementioned Enkei wheels, a black painted front grille, roof rails, and miscellaneous exterior and interior trim bits. It further included heated and cooled seats with power-adjustable bolsters. However, as good as the Sport Package was on a smooth and winding roads, I didn’t like it on the highway; the ride was compromised by the potholes and uneven pavement surfaces of Northern California’s roads. If you care more for the ride, but want upgraded interior trim and the heated/cooled seats, select the $3,300 Deluxe Touring Package which comes with 20-inch wheels too.

As for the interior, the front seats were very comfortable. I drove the QX70S to Napa from San Jose and back in one day (probably four to five hours of driving total) and I or my passenger didn’t feel stiff at all. An aspect of the seat some potential buyers might dislike is that the lumbar support is only adjustable two ways (forwards and backwards). Hopefully, future QX70 models can correct that. Additionally, thanks to the high seating position, I had a much better view of the road unlike most sedans. However, while the front seats are satisfying, there isn’t enough legroom for rear seat passengers. While the back seats are fine for children, most adults can tolerate sitting in the back of the QX70 for two hours at the most, though adults who are well over six feet won’t like sitting in the back at all. As a result, if you regularly travel with many passengers, getting a larger crossover or a midsize luxury sedan may be a better call.

Another aspect of the interior I noticed was that the trunk doesn’t have much more room than a large sedan thanks to the rakish styling. It would be difficult to fit a normal bicycle inside the interior even with all the rear seats folded down. Despite the lack of cargo space, Infiniti does include a temporary spare tire under the trunk placed around the Bose subwoofer. Additionally, I didn’t like the oval-shaped analog clock in the dashboard, which I thought detracted from the sporty interior theme of the QX70. I’m hoping an updated version of the QX70 will have a much-better designed clock.

When it comes to the onboard toys, which is where most Infinitis shine, the QX70 oddly lacks a few key features like the availability of a blind spot monitoring or warning system. However, my test car had the Lane Departure Warning system, part of the $2.950 Technology Package, which does sound if the wheels go onto the shoulder. When I was driving the QX70 on the highway, I ended up turning off the Lane Departure Warning since whenever I swerved to avoid potholes or uneven pavement surfaces (which happens with regularity on California highways), the alarm would sound. The car was also equipped with Forward Collision Warning, warning me if the car in front suddenly slowed down; and Distance Control Assist, which assessed the gap between me and the car in front. Both features were quite useful.

On the subject of fuel economy, the QX70S didn’t deliver as good numbers as I’d hoped. The EPA figures are 17 mpg city and 24 mpg highway with 19 mpg combined for the rear-drive model. All-wheel-drive models are rated at 16 mpg city and 22 mpg highway with 18 mpg combined. For a modern crossover with a V6, the QX70 should deliver better numbers, preferably well over 20 mpg combined. Though I managed around 22.5 miles per gallon, indicated by the display in the gauge cluster, that figure was achieved with plenty of highway driving. Once you hit stop-and-go traffic, fuel economy immediately begins to suffer thanks to the amount of fuel needed to sustain all 3.7 liters of that V6.

The price of my rear-drive QX70 test car came to $58,085 with a $995 destination charge, which is in line with most midsize luxury sport sedans that have similar levels of equipment. Considering a six-cylinder BMW X6, Porsche Cayenne, and the upcoming Mercedes GLE Coupe have prices well above $60,000 with a similar level of equipment (though they all have all-wheel-drive standard), the Infiniti is priced very well. Even at its base price of $46,845 including destination, there’s a plenty of standard equipment such as the Bose sound system, the Infiniti Intelligent key, the 10-way power seats, power-folding mirrors, and power liftgate.

In conclusion, if you want something different from the usual Lexus GS or BMW 5-Series, appreciate a high riding height, don’t want to pay the insane prices for a Porsche Cayenne or BMW X6, and don’t need a large three-row luxury SUV like an Acura MDX or Audi Q7, the Infiniti QX70 might fill that gap. It handles very, very well while maintaining a degree of comfort for the driver and lacks the extra weight and complexity of its competitors. In this day and age, it’s now possible to consider a crossover rather than a sport sedan, and the QX70 is a solid choice if you want a tall, well-handling touring vehicle all to yourself.

Infiniti provided the vehicle, insurance, and one tank of gas for the review.

    " fuel economy immediately begins to suffer thanks to the amount of fuel needed to sustain all 3.7 liters of that V6." Umm.. no. Economy begins to suffer because the engine has all that weight to get moving over and over"

    Having had a 08g35x and a '10 G37s 6mt sedan , I can vouch for reliability, had wheel bearing replaced under the factory warranty on the g37, at 30k , but thats it . For both vehicles. Couldn't say the same for the Bimmers I've owned. Its too bad the q50 is n/a with 6mt... I'll probably pick up a QX50 off lease at some point though.I'd like a turbo 4 in that chassis for commuting MPGs.
