The G-Class keeps elevating the pinnacle of refinement. From its advanced lighting to its classic upright shape, its purposeful elegance is both unmistakable and irrefutable. Its sturdy ladder frame and galvanized steel body are hand-welded. The frame is flowed with hot wax to resist corrosion. Even with its dramatically fresh design, ergonomically optimized layout and advanced luxuries, the G-Class cabin remains a living tribute to a tradition of hand craftsmanship that's all but vanished from the earth. Exquisitely handcrafted designo leather and cabin trim (standard on the G63 AMG) offers an extensive palette of personalization options, with eight colors of Nappa leather, three woods and carbon fiber from which to choose. As you make your way off-road, three sequentially lockable differentials offer increasingly masterful capability. Each differential can be locked in sequence (center, rear, and front) via a set of buttons on the dash, to help maintain the ideal balance of torque and traction for the situation. The 382-hp G550 V-8 generates 391 lb-ft of torque, with an exceptional 75 percent of it on tap at just 1,000 rpm. The G63 AMG is able to crank out 536hp and 560 lb-ft of torque. A dual-stage intake and continuously variable timing of both its intake and exhaust valves enhances efficiency and emissions. The standard G-Class permanent all-wheel drive system continually sends power to all four wheels. Advanced entertainment, navigation and communication systems work with intuitive ease in the G-Class. Bluetooth lets you make calls hands-free and play music wire-free. The elegant central controller and color displays put a world of features within easy reach.
