About the 2015 INFINITI QX70

2nd generation FX/QX70 platform (introduced for 2009 as FX; renamed QX70 for 2014), late-cycle year before the final run of this design.

INFINITI positioned the QX70 as an “iconic performance crossover” rather than a traditional family SUV. Its appeal centered on bold styling, a long-hood/short-overhang shape, a cockpit-style cabin, and handling that leaned more sporty than soft. The QX70’s main draw was giving buyers SUV ride height and premium features without giving up the look and feel of a driver-focused vehicle.

INFINITI positioned the 2015 QX70 3.7 as a stylish, athletic luxury crossover that put sporty road manners ahead of maximum cargo room. Its 325-hp V6 and seven-speed automatic were joined by heated leather-appointed front seats, a power moonroof, Bose 11-speaker audio, and a rearview camera with a 7-inch display.

Frequently asked questions

What changed on the 2015 INFINITI QX70 compared with the 2014 model?

The main change was the discontinuation of the 5.0-liter V8 model. The 3.7-liter V6 version otherwise carried over without a redesign or a broad safety, technology, styling, or structural update.

Does the 2015 INFINITI QX70 have a V8?

No. The V8-powered 5.0 model was dropped for 2015, so the remaining QX70 used a 325-hp 3.7-liter V6 with a seven-speed automatic.

Was the 2015 INFINITI QX70 redesigned?

No. The 2015 QX70 continued the second-generation design introduced for 2009 as the FX and renamed QX70 for 2014.

Did the 2015 INFINITI QX70 receive new safety or infotainment features?

No broad safety or infotainment upgrade arrived for 2015. The QX70 3.7 retained equipment such as a rearview camera with a 7-inch display, USB connectivity, and Bose 11-speaker audio.

Is the 2015 INFINITI QX70 a major upgrade over the 2014 model?

No. The 2015 model is largely a carryover from 2014, and its key difference is that the V8-powered 5.0 model is gone. Shoppers who want the V8 should look at the 2014 QX70 5.0 instead.

“The best design on an SUV. This model was at the forefront before everyone brought out similar models.”

2015 INFINITI QX70 V6 AWD

“Wonderful car, well equipped, good looking, different from any other SUV, as an owner of multiple Porsches, this is my Japanese Porsche SUV! Love this vehicle, but: access door to gas tank is "puny", and way too flimsy, they could have done better!”
