Formerly known as the FX before Infiniti completely changed up its naming convention, the QX70 is a very sporty mid-size crossover with a striking design. It is one of the more entertaining sport utes, both visually and from behind the wheel. The Infiniti QX70 name has very little history behind it, but the model actually goes back a while.
The brand's new naming convention means model names no longer include a nod to engine displacement, so the former FX37 and FX50 are now both known simply as the QX70. Badges to denote engine displacement—3.7 or 5.0—live on the front fenders. For a full explanation, and a cheat sheet, check out our story on Infiniti's naming strategy, which further discusses these changes.
The QX70 conveys style and grace with its curvaceous exterior and warm cabin appointments. Other FX strengths that carry over to the QX70 include the performance of a sport sedan, plus an all-around attitude that for a number of reasons makes it a standout versus either family-oriented premium crossovers or more truck-like luxury SUVs. Rival models have included the Acura MDX and now-defunct ZDX, BMW X5 and X6, Range Rover Sport, Porsche Cayenne, and Mercedes-Benz ML/GLE.
The QX70 has a sleek interior featuring rich finishes and available quilted leather seating that gives it a very upscale feel. Front-seat comfort is top-notch, and the view over the rippled hood is higher than a car's but lower than that of some SUVs, a nice compromise. Space is a bit limited in the rear seats as a result of the sloping roofline, and the storage behind is likewise reduced. The high cargo floor doesn't help much, either. Like in some other slant-back SUVs, sporty style takes precedence over utility.
With a 328-horsepower, 3.7-liter V-6 as the standard engine (with rear- or all-wheel drive), the QX70 has strong acceleration; but those who want the strongest, quickest QX70—and the one with the most attitude—will go for the 390-horsepower, 5.0-liter V-8, which only comes with all-wheel drive. We tend to think handling is at its best in the QX70 with the V-6 and rear-wheel drive, though; that's where it feels most like a sport sedan, and V-8 models tend to feel a bit ponderous. But even then, it's all relative; the QX70 is one of the best-handling crossovers or utility vehicles of any kind, while the seven-speed automatic transmission fits the performance personality, with downshift rev-matching and steering-wheel paddle shifters.
The QX70's V-8 creates a unique sound signature, with a low burble at idle and some sweet notes at full throttle. Compared to other luxury SUVs, the QX70 lets more sound into the cabin, but at least it is pleasant to listen to. That said, road noise accompanies the eight-cylinder soundtrack, with the big tires making themselves known on grooved pavement and uneven surfaces, which can burst the luxury bubble for some.
The QX70 comes in three different models—QX70 3.7, QX70 3.7 AWD, and QX70 5.0 AWD. QX70 models top $60,000 when you add the contents of the Premium, Deluxe Touring, and Technology packages. Big-ticket tech options include a lane-departure warning and prevention system, an adaptive suspension, adaptive bi-xenon headlamps, and a navigation system with an especially good display and interface. Other standalone options on the QX70 include a rear entertainment system with dual headrest-mounted monitors, roof-rail crossbars, a cargo organizer, and a Tow Package.
