2024 Mercedes-AMG GLS63 Review Pricing and Specs

Overview

With a 603-hp twin-turbo V-8 engine and an AMG-massaged air suspension, the 2024 GLS63 is a luxury SUV for the power-hungry. Its roaring powertrain propelled it to 60 mph in just 3.6 seconds at our test track, and with seating for up to seven passengers, it’ll get the school run done nearly as quickly. Straight-line performance is its forte though, as the GLS63’s handling—while perfectly acceptable for the performance SUV class—isn’t as athletic as the brand’s super sedans and sports cars. Its ride is firm, especially on the optional 23-inch wheels, so if you’re looking for max comfort, you’ll want to look at the Benz-branded GLS instead. Comfort and technology features are nearly identical to that less-aggressive model, and they include a wall of digital displays on the dashboard, contemporary connectivity features, supportive seats, high-end materials, and plenty of style.

What’s New for 2024?

The GLS63 gets an updated set of taillights for 2024 plus new 21- 22- and 23-inch wheel designs. New puddle lamps illuminate the ground below when the front doors are opened, and the Benz logo above the grille has been replaced by an AMG-specific one. The GLS63’s brake calipers have been painted red this year as well, and a new steering wheel dresses up the cabin. More interior color options have been added and Mercedes has included more standard equipment, including a panoramic sunroof, heated and ventilated front seats, automatic high-beam headlamps, and a performance exhaust system.

Pricing and Which One to Buy

Although the GLS63’s starting price is deep into the six-figure realm, we’d still suggest a few options sure to 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, and a heated center console. We’d also suggest the Energizing package which includes the in-cabin fragrance diffuser and the Acoustic Comfort package which 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, and 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 and air suspension. We were blown away by the GLS63’s performance at our test track as it out-accelerated several hot sports cars we’ve tested, 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 to a feeling of unflappable precision when cornering, though it does offer plenty of grip to have some fun with on a twisty road.

Fuel Economy and Real-World MPG
