Based on the Toyota 4Runner, the Lexus GX has all of the 4Runner's exceptional off-road capabilities but with more than a little bit of Lexus luxury. To help this mastodon thrive in all conditions, Lexus installed a 4.6-litre V8 that produces 301 horsepower and 329 pounds of torque. Although designed for work, the Lexus GX proves to be a quiet and comfortable vehicle.
