2022 Mercedes-Benz GLS vs 2021 Lexus GX

ost modern SUVs are really car-based crossovers—lifted station wagons, or minivans without the sliding doors. That’s not the case with the 2021 Lexus GX 460.

Like the mythical Loch Ness Monster, the GX is a creature that time forgot. It’s one of the last SUVs with truck-like body-on-frame construction and true off-road capability. That’s because the GX is actually a rebadged Toyota Land Cruiser Prado (a smaller version of the iconic Toyota Land Cruiser not sold in North America), and is related to the Toyota 4Runner. It’s also genuinely old: the current generation dates back to the 2010 model year, and Lexus has kept it in production with some updates of styling and tech over the years.

That makes the GX a fairly odd proposition on the new-car market. It has the off-road capability, not as a lifestyle statement, but because that’s what was still expected of SUVs when it was launched. The GX sits between the RX and LX in the Lexus lineup but has little direct competition. Its only real rival is the much newer Land Rover Discovery.

For the 2021 model year, the GX gets some minor updates. Lexus continues to offer only the GX 460 model, with a single powertrain option, a standard four-wheel drive (4WD) drivetrain, and two pricing levels: base, or the Executive package.

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.
