With a whopper of a twin-turbo V-8 engine under its hood, the 2022 Mercedes-AMG GLS63 kicks the performance of the standard GLS-class SUV up khổng lồ an entirely new level. This hot-rod has rivals such as the BMW X7 M50i & the Cadillac Escalade V-series in its crosshairs. A sport-tuned air-suspension is standard and spices up its over-the-road behavior, although it comes with a much stiffer ride. That"s not khổng lồ say the GLS63 isn"t luxurious. It"s leather-lined cabin is finished with upscale materials, & it’s both spacious & extremely comfortable—at least in the first two rows. A host of tech features comes standard & even more advanced items, such as a semi-autonomous driving mode, are available as options.





What"s New for 2022?

The mighty GLS63 is largely unchanged for 2022. We were worried it wouldn"t happen at all this year due khổng lồ supply chain issues that Mercedes reported were holding up production. But we"ve confirmed that the GLS63 is back in business and ready khổng lồ thrill your family with its 603-hp twin-turbo V-8.

Pricing & Which One lớn Buy

Although the GLS63"s starting price is deep into the six-figure realm, we"d still suggest a few options sure lớn please the whole family. For one thing, the Warmth and Comfort package is a nice bundle for those in northern climates, as it adds heated door panels, heated armrests, và a heated center console. We"d also suggest the Energizing package which includes the in-cabin fragrance diffuser and the Acoustic Comfort package, & also adds increased cabin insulation for a quieter interior. Mercedes-AMG also offers a host of standalone features that may catch your eye, including the bonkers 23-inch multi-spoke forged wheels that look just perfect when framed within the GLS63"s muscular wheel wells.

Engine, Transmission, và Performance

Under the hood of the GLS63 is a twin-turbocharged 4.0-liter V-8 engine that makes a whopping 603 horsepower with the help of a 48-volt hybrid system. All-wheel drive is standard, as is a nine-speed automatic transmission và air suspension. We were blown away by the 2021 GLS63"s performance at our test track as it out-accelerated several hot sports cars we"ve tested recently, tearing off a blistering 3.6-second zero-to-60-mph run. For comparison, the old GLS63—which made a mere 577 horsepower—managed a none-too-shabby 4.3-second zero-to-60-mph run. As impressed as we were with the GLS"s acceleration, we can"t say the same for its driving dynamics. The ride is firm, especially on the optional 23-inch wheels, but that firmness doesn"t translate khổng lồ a feeling of precision when cornering. The GLS"s toàn thân bobs across road undulations more than expected, though it still offers plenty of grip lớn have some fun with on a twisty road.

Interior, Comfort, & Cargo

Three rows of seating và interior styling that"s slightly sportier versus the Benz-branded GLS-class sets the GLS63 apart from two-row SUV powerhouses such as the BMW X5 M and the Audi RS Q8. Lượt thích those competitors, the GLS63 is gorgeously appointed inside. Soft leather covers nearly every square inch of the cabin, và those areas that aren"t leather-wrapped are treated to lớn genuine wood trim & tastefully applied chrome; buttons and knobs are rendered in a rich-looking metallic finish. Front-seat occupants can enjoy a mas sa while blasting down the Interstate, và passenger space is generous in the second row, which can also be equipped with heated seats & power sunshades. The third row of seats is tight for adults but perfectly suitable for children. Cargo space is the same as the standard GLS-class, which in our testing fit four carry-on suitcases behind its third row và 30 in total behind the front seats.
