  • Marginal fuel economy
  • Limited cargo space

New for 2015

2015 Infiniti QX70 Overview

Is the 2015 Infiniti QX70 a Good Used SUV?

The Infiniti QX70 is a fine option if you want a luxury midsize SUV with sports-car-like performance. That said, it’s far less appealing as a people- or cargo-hauler. The 2-row QX70 shares its platform with the Nissan 370Z, and like its sports car cousin, it has sharp handling and a potent engine. Its interior is also well-appointed, the infotainment controls are user-friendly, and many advanced safety features are available. The catch is that the ride can be harsh, the rear seats are cramped, and the cargo space is slim.

Used 2015 Infiniti QX70 Performance and Interior

The Infiniti QX70 has a 3.7-liter V6 engine with 325 horsepower. A seven-speed automatic transmission and rear-wheel drive are standard; all-wheel drive is available. The muscular V6 packs more than enough punch to zip the QX70 up to speed with ease, and the refined automatic produces quick, smooth shifts. The transmission also has a manual mode with downshift rev matching, which allows the driver to make quicker, more controlled gear changes. The Infiniti feels secure and well-balanced when rounding tight corners. The steering is precise and nicely weighted, and the brakes offer confident stopping power.

The QX70 makes a few compromises, however. The taut suspension produces a firm ride, which can be rather uncomfortable on bumpy roads. The V6 returns low fuel economy of just 17 mpg in the city and 24 mpg on the highway (16/22 mpg city/highway with AWD). The QX70 also has a towing capacity of just 2,000 pounds (AWD only), which is much less than what its midsize SUV rivals can handle.

The five-seat Infiniti QX70 complements its sporty exterior with a luxe and clean-cut interior. The plush, nicely contoured front seats provide fine comfort on long trips. A set of optional sport seats with power-adjustable side bolsters offer extra hip-hugging support. Heated leather seats are standard; cooled seats are available. The QX70’s rear seats aren’t very comfortable, however. Legroom is slim for adults and headroom is tight due to the crossover’s sloping roofline. There are two full sets of LATCH connectors for securing child car seats. The slender roof also produces blind spots and cuts into usable cargo space. The QX70 offers 24.8 cubic feet of cargo room with its rear seats upright and 62 cubic feet with the seats folded, which is smaller than what many competitors provide.

Infiniti equips all QX70 crossovers with a 7-inch display screen, Bluetooth, a USB input, and satellite radio. The elegant dashboard features a simple button layout for all audio and climate functions, as well as a user-friendly controller for handling the infotainment system. Buttons at either side of the controller make it easy to jog through menus and access features quickly. Available equipment includes a navigation system, a larger 8-inch touch screen, voice recognition, and real-time traffic and weather alerts. The QX70’s cabin materials benefit from a high-quality look and feel.

Should I Consider Another Used QX70?

Updates for 2015 include the discontinuation of the QX70’s available V8 engine, active rear-steering system, and adaptive suspension.

Infiniti CPO vehicles must pass a 167-point inspection. Extra benefits like towing and roadside assistance may be available, so read the Infiniti warranty page carefully.

2015 Infiniti QX70 and Other SUVs to Consider

Which Is Better: 2015 Infiniti QX70 or 2015 Infiniti QX50?

The 2015 Infiniti QX50 is essentially a smaller version of the QX70. This has its benefits; each shares the same muscular V6 and offers sharp driving dynamics. It also has its shortcomings. Rear-seat and cargo space are in short supply in both models, and neither is very fuel-efficient. You should give higher-rated competitors a look in the luxury compact and midsize SUV classes before settling on either of these.

Which Is Better: 2015 Infiniti QX70 or 2015 Infiniti QX60?

The 3-row Infiniti QX60 is about the same size as the QX70, but it can seat seven passengers – and in reasonable comfort, too. The QX60 offers a smoother ride, a larger total cargo space, and superior fuel economy thanks to its available hybrid system (26/28 mpg city/highway). While it’s still not a top pick in this class due to its below-average reliability rating, it is a better option than the QX70.
