Mercedes-Benz originally designed the G-class as a military truck for the German army, replacing a Volkswagen design that was similar to the United States Army Jeep from World War II. The G-class remains popular enough as a luxury SUV that Mercedes-Benz continues to produce it and export it around the world. This version is enhanced by Mercedes-Benz's high-performance AMG division, giving it better on-road performance.
Part of the G-class' appeal is its legendary off-road capability. Its body-on-frame architecture gives it a rigid platform for the axles, full-time four-wheel drive, and three switches that lock the center, rear, and front differentials.
The G63's dimensions enhance its off-road capability. Although it looks massive, it is less than 15.5 feet long. The driver position is higher than in most vehicles, and the hood is low, giving the driver good forward visibility.
