Mercedes-Benz adds a bit of edge to its rugged G63 AMG by unveiling plans of a 6×6 edition which will be soon available to order. The Mercedes-Benz G63 AMG 6×6 sports a pickup-truck body, a twin-turbocharged 5.5L AMG V8 that delivers 536hp, a seven-speed automatic transmission, and all-wheel drive. Production is expected to begin this October, although pricing hasn’t been announced. Mercedes-Benz plans on building 20 to 30 of the luxury off-roader a year.
