All 2015 Infiniti QX70 models come with a 3.7-liter V6 engine. (The 5.0-liter V8 option is no longer available.) Last redesigned for 2009, the large crossover SUV based on the Nissan Z architecture is not significantly changed for 2015.
Nissan’s luxury division gave all of its models new nomenclature phased across the 2014 and 2015 model years. The QX prefix indicates a sport-utility vehicle, and the 70 in QX70 denotes its relative size: Formerly known as FX, the QX70 is smaller than QX80 (previously QX56), larger than QX60 (previously JX) and QX50 (formerly EX). All 2015 QX70 models are QX70 3.7 models.
An optional Sport Package, new for 2015 QX70 models, includes dark-finish exterior accents and 21-inch aluminum-alloy wheels, holding 265/45VR21 tires. Also in the 2015 Infiniti QX70 Sport Package are climate-controlled sport seats with manual thigh extenders and contrast stitching, four-way power bolster adjustment, aluminum pedals, adaptive front lighting, and magnesium paddle shifters. Otherwise, QX70 is unchanged from the 2014 models.
The QX70 uses rear-wheel drive, the QX70 AWD has all-wheel drive. Vehicles based on rear-wheel drive generally have sportier handling than those based on a front-wheel drive layout, and that holds true for the QX70. QX70 uses some of the same basic architecture as the Nissan Z and Infiniti Q60 two-door sports cars and Infiniti Q40 sedan. Its rear-wheel-drive platform translates to impressively sporty characteristics, whether ordered with all-wheel drive or not.
The Infiniti QX70 is a relatively large luxury crossover SUV that delivers sporty handling and a responsive engine. Designed for performance and style, the Infiniti QX70 avoids the boxy proportions of traditional SUVs. The QX70 offers some usable cargo space, but not as much back-seat room and luggage space as the boxier SUVs, in spite of its large size.
Fuel economy for the 2015 Infiniti QX70 is an EPA-estimated 17/24 mpg City/Highway; the 2015 QX70 AWD is rated 16/22 mpg.
Primary competition for the Infiniti QX70 comes from the rear-wheel-drive BMW X6, which costs significantly more.
We find the wild styling of the QX70 appealing, though not everyone agrees; it’s something of a love/hate question. Unlike most manufacturers of crossovers and SUVs, Infiniti found a way to make its creation stand apart from the pack. This vehicle is not bland.
Infiniti coined the term bionic cheetah for the original FX to denote its sleek, low, stretched-out stance, as well as its tenacious roadholding prowess. That succinct description remains for the current Infiniti QX70, summarizing its distinctively lithe and slender visual aura, coupled with the fact that it approaches the best of the competition in roadholding talents.
While the exterior styling of the QX70 tends to be polarizing, its interior appears to earn approval from most observers. Touring Package cars, in particular, feature fine details, nicely stitched quilted leather seat upholstery, expertly stained maple wood, and matte-finish surfaces that provide a nice respite from the chrome-plated plastic found in many other vehicles.
Technology abounds, led by the available Around View Monitor, which displays images of everything around the QX70 on the navigation display. Smart cruise control, voice-recognition navigation with real-time weather and traffic, rear-seat entertainment systems, and a host of other electronic items are available.
