2021 Mercedes-Benz GLS vs 2021 Volvo XC90

The “S” in the 2021 Mercedes-Benz GLS name is meant to connect the SUV to the S-Class flagship sedan. In this sense, the GLS is the S-Class of SUVs, and it delivers on that positioning. The 2021 GLS-Class has three rows of spacious seating, and puts comfort above all else. The GLS can hold groceries, weekend bags, antique desks purchased from a roadside consignment shop—all things that would require a lot of negotiating in the S-Class sedan.

The GLS is one member of a growing fraternity of full-size, three-row, luxury SUVs. Their ranks include the Cadillac Escalade, Lincoln Navigator, Infiniti QX80, and the more recent BMW X7. The GLS sets itself apart with a higher standard of luxury, and impressive performance… if you’re willing to shell out the cash.

Volvo may be known for sensible station wagons, but the XC90 SUV is the Swedish automaker’s de facto flagship. The current generation debuted design features, technology, and powertrains that have since found their way into most other Volvo models. Several years into the current-generation model’s lifecycle, the XC90 is no longer a trendsetter, but remains Volvo’s contender in the competitive midsize luxury SUV segment, with the automaker’s typical emphasis on safety features.

The current-generation XC90 launched for the 2016 model year, so most competitors—including the Audi Q7, Acura MDX, BMW X5, and Mercedes-Benz GLE—have been updated or redesigned since then. The Cadillac XT6 and Lincoln Aviator didn’t even exist when this generation of XC90 launched.

A redesigned version is expected to arrive soon, so changes to the 2021 XC90 are minimal. All 2021 Volvo models are now limited to 180 kilometres per hour for safety reasons. The XC90 also gets a handful of newly standard tech features, and some small cosmetic changes.

Volvo offers the XC90 in three trim levels—Momentum, R-Design, and Inscription—with three powertrain options: T5 and T6 gasoline engines, and the T8 plug-in hybrid. Our test car was a range-topping T8 Recharge Inscription, combining the top Inscription trim level with the plug-in hybrid powertrain, which has the highest output of the three.
