2015 Infiniti QX70 Overview

Is the 2015 Infiniti QX70 a Good Used SUV?

The 2015 Infiniti QX70 is a decent used luxury midsize SUV. It appeals more to drivers who prefer more-athletic vehicles, but it comes up short in some key areas. Many class rivals have more space for passengers and cargo, and several get better gas mileage. On top of that, while the QX70's interior is nice, it's still a step below the most upscale cabins in the class.

Is It Better to Buy a Used or New QX70?

Which Model Year of the Infiniti QX70 Is Best?

The 2015 QX70 marks the seventh model year of the vehicle’s second generation. It was previously known as the Infiniti FX from 2009 to 2013.

Updates for 2015 include the discontinuation of the QX70’s available V8 engine, active rear-steering system, and adaptive suspension. These were the last major changes to the QX70 before the vehicle was discontinued following the 2017 model year. If you're looking for the best value, consider the 2014 model, which will likely save you some money and give you access to more available features than the 2015.

2015 Infiniti QX70 Versus the Competition

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

The 2015 Infiniti QX50, which is a luxury compact SUV, 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 2015 Infiniti QX60 is about the same size as the QX70, and it sits near its sibling in our luxury midsize SUV rankings. However, the three-row QX60 can seat seven passengers –in reasonable comfort too. The QX60 offers a smoother ride, a higher maximum cargo capacity, and superior fuel economy thanks to its available hybrid system, which returns 26/28 mpg city/highway. The QX60 gets a poor reliability rating, but in most other ways, it's a better option than the QX70.

2015 QX70 Performance

How Does the 2015 Infiniti QX70 Drive?

The QX70 features a 3.7-liter V6 engine that puts out 325 horsepower. This engine delivers plenty of power and a pleasant exhaust note. The standard seven-speed automatic transmission is mostly responsive, though it occasionally hesitates to downshift.

This Infiniti handles better than many of its classmates. It's agile and sure-footed around turns, and the small turning radius makes it easy to maneuver. The ride is firm, but not to the point of discomfort. Rear-wheel drive comes standard in the QX70, and all-wheel drive is available.

Does the 2015 Infiniti QX70 Get Good Gas Mileage?

The 2015 QX70 gets slightly below-average fuel economy for the class. Rear-wheel-drive models earn 17 mpg in the city and 24 mpg on the highway, and all-wheel-drive models return 16/22 mpg city/highway.

2015 Infiniti QX70 Towing Capacity

When properly equipped, the 2015 QX70 can tow up to 2,000 pounds.

How Many People Does the 2015 QX70 Seat?

How Many Child Car Seats Fit in the 2015 Infiniti QX70?
