Why it stands out

The 2023 Mercedes-Benz G-Class stands out because it blends an unmistakable military-grade shape with the kind of luxury and technology buyers expect from a modern Mercedes. Its appeal is rooted in that contrast: the SUV still looks like a rugged off-roader, but it was completely redesigned in 2019 as a luxury off-road machine with modern systems, lightweight structural materials, and a much plusher interior. It also uses Mercedes-Benz MBUX infotainment on a flat-panel dashboard with two 12.3-inch displays, and it adds driver-assist and safety features developed for other Mercedes models.

For 2023, the G-Class is offered in two main forms, the G 550 and the AMG G 63. The G 550 uses a twin-turbo 4.0-liter V8 that makes 416 horsepower and 450 pound-feet of torque, while the AMG G 63 uses a handcrafted twin-turbo 4.0-liter V8 with 577 horsepower and 627 pound-feet of torque. That gives the G-Class serious performance to go with its off-road ability, but fuel economy is a clear weakness: the G550 returns 14 mpg city, 17 highway, and 16 combined, while the G63 hits just 13 city, 16 highway, and 14 mpg combined.

What makes the 2023 model especially appealing is that it delivers the G-Class experience buyers want without losing the truck’s core identity. It remains highly customizable, and Mercedes offers a wide range of options and special trim packages. At the same time, it is still expensive to buy and maintain, and its limited production means used examples can be hard to find. For shoppers who want a luxury SUV with iconic styling, strong power, and genuine off-road capability, that combination is exactly the point.
