Mercedes-Benz's iconic G-wagen SUV has roots as a military vehicle, but the high-performance 2022 Mercedes-AMG G63 model serves an entirely different driver than the 1970s original. A 577-hp twin-turbocharged V-8 engine gives the G63 incredible performance, and its posh cabin offers all the modern amenities we've come to expect from a top-spec Mercedes. A host of infotainment and other tech features that would have seemed like science fiction to the designers of the original truck are standard.
