About the 2009 Mercedes-Benz G-Class
W463 original generation, late-cycle update year for the U.S. G-Class and the first year for the G550 badge.
Mercedes-Benz positions the G-Class as a hand-built luxury SUV with genuine off-road hardware, not a soft crossover dressed up to look rugged. Its core appeal is the mix of old-school toughness—body-on-frame construction, low range, and locking differentials—with upscale materials, strong V8 power, and unmistakable boxy styling. Buyers choose it because it feels rare, durable, and purposeful in a way most luxury SUVs do not.
The G550 is the core luxury and off-road model, pairing full-time four-wheel drive, low range, and three locking differentials with leather seating, navigation, and a rearview camera. The G55 AMG is the performance version, with a 500-hp supercharged V8, side-exit exhaust pipes, stronger brakes, and a Designo leather cabin. Both retain the G-Class’s serious four-wheel-drive hardware.
