Last updated August 4, 2026

About the 2023 Mercedes-Benz G-Class
2nd gen (2019-2024), fifth model year before the 2025 update
The G-Class is Mercedes-Benz's icon SUV for shoppers who want true off-road hardware and unmistakable presence without giving up a luxury cabin. Mercedes centers the model on handcrafted construction, timeless boxy design, and trail-ready capability, while reviews note that the G 550 backs up the image with low-range gearing, locking differentials, and a strong V8. Compared with other luxury SUVs, its appeal is authenticity, capability, and image more than efficiency or family-space value.
The G 550 remains the core G-Class, pairing a 416-hp twin-turbo V8 with full-time four-wheel drive, low-range gearing, and three locking differentials. Its five-seat cabin has leather upholstery, heated front and rear seats, and two 12.3-inch displays, while the AMG G 63 4x4 Squared serves as the range’s more extreme model.

2023 Mercedes-Benz G-Class
(167 reviews)
“I am eager to get behind the wheel and drive! I feel safe, in control of my surroundings, relaxed, and comfortable.”
“Awkward to get into vehicle. Running boards should extend out and down for entry. Keyless entry. For the cost of a G it is unbelievable to not have that option. Steering wheel too small to see info on dashboard.”
