2022 Mercedes-Benz GLS-Class, Pricing, Specs, Photos

There are two models, the GLS450 with six cylinders and the GLS580 with eight cylinders. Both have some hybridization. The GLS450’s 3.0-liter turbocharged inline-six engine runs smoothly and makes 362 horsepower. The GLS580 is much more powerful. Its twin-turbocharged 4.0-liter V-8 gives it 483 horsepower.

At our test track, it took the GLS450 only 5.5 seconds to get to 60 mph, and it only took 154 feet to stop from 70 mph. Even though it’s big, the GLS-class is easy to drive quickly on a winding road.

According to the EPA, the GLS-class doesn’t get very good gas mileage. The GLS450 gets 19 mpg in the city and 23 mpg on the highway, for a total of 21 mpg. The GLS580 gets 16 mpg, 21 mpg, and 18 mpg, which is worse. The GLS450 did a little better than its rating in our real-world tests, getting 24 mpg on our 200-mile highway loop.

The dashboard is mostly made up of two huge digital displays that are 12.3 inches each. One is a display for the driver’s gauges that can be changed, and the other is for entertainment and runs Mercedes-new Benz’s MBUX software, which has a virtual assistant like the one on the iPhone.
