Overview

The 2017 Mercedes-Benz G-Class is a boxy, body-on-frame luxury SUV known for serious off-road hardware and an iconic design that has barely changed for decades. This model year sits in the long-running W463 generation (pre-2019 redesign), blending old-school toughness with high-end materials and strong V8 performance. It’s ideal for drivers who want a prestige SUV with true 4x4 capability, a commanding driving position, and unmistakable curb appeal. In the luxury market, the G-Class competes more on character, capability, and exclusivity than on ride comfort or modern packaging.

Key Features

- Powerful V8 engine lineup: Most 2017 G-Class models use a 5.5L twin-turbo V8 in the AMG G 63, delivering very strong acceleration and passing power, paired with a 7-speed automatic transmission and standard all-wheel drive. - True off-road drivetrain: Standard full-time 4MATIC all-wheel drive with low range and three locking differentials (front, center, rear) makes the 2017 G-Class one of the most capable factory SUVs off-road. - Classic body-on-frame construction: A rugged ladder frame, solid feel, and tall ground clearance are key reasons buyers choose the G-Class over more car-like luxury SUVs. - Upscale, durable interior: Premium leather, strong switchgear, and an upright cabin layout provide a distinctive “luxury utility” feel, with available driver-assistance and infotainment features depending on trim and options. - Strong towing and all-weather confidence: Owners value the stable, planted feel in poor weather and the ability to handle steep grades and rough terrain when properly equipped.
