2015 Infiniti QX80 Overview

Is the 2015 Infiniti QX80 a Good Used SUV?

The Infiniti QX80 is a decent option if you’re shopping for a used luxury SUV. The QX80 has a spacious interior with seating for up to eight, a muscular V8 engine, and a well-tuned suspension that balances a comfortable ride with surprisingly agile handling. Additionally, used models are often priced lower than other luxury SUVs in this segment.

That said, the QX80 returns poor fuel economy, and it can be awkward to park in tight areas. It also trails luxury large SUV alternatives like the 2015 Toyota Land Cruiser and 2015 Lincoln Navigator in terms of reliability and projected ownership costs. Before you buy, consider these higher-rated SUVs.

Which Model Year of the Infiniti QX80 Is Best?

Infiniti launched the second generation of the QX80 for the 2011 model year. It was called the QX56 from 2011 to 2013, then renamed the QX80 for 2014. Aside from this name change, this SUV hasn’t had many updates. It received lightly restyled bumpers and headlights for the 2015 model year. A more significant styling refresh arrived for 2018.

As a result, you can buy a used 2011 or 2012 QX56 with similar features and performance as the newer 2016 and 2017 QX80 models. The asking prices of these older models are apt to be much lower as well.

2015 Infiniti QX80 Versus the Competition

Which Is Better: 2015 Infiniti QX80 or 2015 Lexus LX?

The 2015 Lexus LX is one of the best SUVs in this segment. The LX 570 has an excellent reliability rating, a powerful V8 engine, and a rugged drivetrain, making it well-suited to survive tough conditions both on- and off-road. The LX also has a quality cabin, many available safety features, and a user-friendly infotainment system. Though it’s not as roomy inside as the QX80, the LX is a better pick for most shoppers.

Which Is Better: 2015 Infiniti QX80 or 2015 Mercedes-Benz GL?

The 2015 Mercedes GL is another great pick in the luxury large SUV segment. The GL has an opulent interior with top-notch materials, spry handling, and a relaxing ride. It also offers a similar array of safety features as the QX80. The GL stands apart for its engine options though. It’s offered with potent twin-turbo V6 and V8 engines that provide breakneck acceleration. It can also be equipped with an efficient turbodiesel that gets a class-leading 19/26 mpg city/highway. The GL is often a bit pricier than the QX80, but it’s money well spent.

2015 QX80 Performance

How Does the 2015 Infiniti QX80 Drive?

The Infiniti QX80 feels agile for such a large SUV, and it remains stable around turns. Its steering is light and responsive, and its suspension soaks up most bumps and dips in the road, especially when equipped with the standard 20-inch wheels. The QX80 is fairly capable off road. It flexes nicely over rocks and ruts, and it offers a decent 9.2 inches of ground clearance. That said, the QX80 has a wide turning radius, and it can be tough to maneuver and park in tight areas.

The QX80 comes paired with a 5.6-liter V8 engine with 400 horsepower. A seven-speed automatic transmission and rear-wheel drive are standard; four-wheel drive with high- and low-range gearing is available. This brawny V8 hustles the QX80 up to speed with confidence, and it supplies more than enough muscle for climbing hills, passing other vehicles, and pulling a trailer.

Does the 2015 Infiniti QX80 Get Good Gas Mileage?

The QX80 gets poor fuel economy. Its big V8 engine manages just 14 mpg in the city and 20 mpg on the highway.

2015 Infiniti QX80 Towing Capacity

The QX80 is rated to tow up to 8,500 pounds when properly equipped.
