Based on the new Toyota Land Cruiser, the GX 550 rides on a body-on-frame architecture and  focuses on off-road capability. But its priorities are towards utmost passenger accomodation and on-road refinement. All GX 550 varaiants are powered by a 349-hp twin-turbo V-6 working through a 10-speed automatic and full-time, four-wheel drive with low range. The GX is one of those vehicles that balance their upscale appointments with an equal amount of off-road capability.
