2022 Mercedes-Benz GLS vs 2021 Volvo XC90

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.

The SUV that’s now known as the GLS was launched for the 2007 model year as the GL-Class, when Mercedes decided it needed a bigger, more luxurious SUV to sit above the M-Class in its lineup. The GL-Class and M-Class were rebadged the Mercedes-Benz GLS-Class and GLE-Class, respectively, in 2014 when Mercedes introduced a new naming scheme across its lineup.

The current version of the GLS was introduced for the 2020 model year, and represents the model’s third generation. It’s aimed at other full-size luxury SUVs, including the BMW X7, Cadillac Escalade, Infiniti QX80, Land Rover Range Rover, Lincoln Navigator, and Lexus LX.

Four models are available in Canada: the base six-cylinder GLS 450 4Matic, the GLS 580 4Matic, the AMG GLS 63 4Matic+, and the Mercedes-Maybach GLS 600 4Matic. Availability is currently limited, and specifications for the 2022 model year are not available. However, they are expected to be very close to those listed for 2021, which were used as reference for the information provided here. We tested a U.S.-specification 2022 GLS 450 for this review.
