About the 2018 Mercedes-Benz AMG G-Class
First-generation U.S.-market G-Class (W463), final model year before the fully redesigned 2019 second generation
Mercedes-Benz positioned the AMG G-Class as a rare combination of hand-built high performance, traditional off-road hardware, luxury equipment, and unmistakable upright design. Its core identity is a rugged, body-on-frame SUV with low-range four-wheel drive and three locking differentials, transformed by powerful AMG engines, stronger brakes, sport-focused hardware, and a richly equipped cabin. Few competitors combine this level of straight-line performance with such specialized trail capability and recognizable styling.
The G 63 AMG pairs a 563-hp twin-turbo V8 with permanent four-wheel drive, low range, and three locking differentials. The G 65 AMG is the V12 flagship, producing 621 hp and 738 lb-ft of torque. Both have heated and ventilated front seats, an 8-inch infotainment screen, smartphone integration, adaptive cruise control, and blind-spot monitoring.
