2018 Mercedes-Benz GLS Exterior Driver Side Front Angle vs 2018 INFINITI QX80 Exterior Driver Side Profile

There are a host of full-size luxury crossover utility vehicles out there on the market, but in our opinion, one is far superior to the rest. Of course, our opinion might be a bit biased, so we thought we’d prove it to you by comparing it to one of its biggest competitors. To do this, we’ve pit the 2018 Mercedes-Benz GLS vs 2018 Infiniti QX80.

As you can see from one glance at the table below, the two vehicles are quite comparable to one another, but each has its advantages. We’re going to go through row by row to explain the advantage and figure out exactly why each might make the better option for you.

2018 Mercedes-Benz GLS



17 mpg City Fuel Efficiency 14 mpg
22 mpg Highway Fuel Efficiency 20 mpg
362 HP Horsepower 400 HP
7 Seating 7

Advantages of the 2018 GLS

The first half of the table looks at fuel efficiency, starting with the economy you’ll get on city streets, in which the GLS achieves an extra 3 mpg. Then the second row jumps onto the highway, where the GLS still has an advantage, but of 2 mpg instead of 3.

While neither of those advantages are particularly mind-blowing, it is plenty to save you a bit of cash at the pump over time. However, unfortunately, the GLS does give up 38 horsepower to the QX80 as a result of the superior efficiency. The fourth row shows that the two luxury crossovers are matched in seating capacity at 7 passengers each.

In other words, if you’re looking for a more efficient luxury crossover, then the 2018 Mercedes-Benz GLS is the right option for you. If you’re comfortable giving up some efficiency for extra horsepower, then the INFINITI QX80 might be for you, but 38 horsepower isn’t a massive advantage either.
