Wider, taller, and meaner than its showroom cousin, the Nissan Titan Warrior Concept is yet another design exercise we’d like to take for a spin — in the dirt, not on the road. The rugged truck sits three inches higher than stock, and is six inches wider, as well, both necessary to fit the 37-inch off-road tires that sit on 18-inch dark matte aluminum alloy wheels. The Cummins 5.0L V8 Turbo Diesel engine provides plenty of power, LED lighting in both the front and rear (and roof) ensures visibility, and the carbon fiber spoilers on the rear cab and tailgate reduce drag when speeding across the wilderness.
