Selection is very important to pickup buyers, and at Nissan they can choose between the standard TITAN and the beefier TITAN XD; single cab, king cab or crew cab; long or short bed; 4x2 or 4x4; a gasoline V8 rated at 390 horsepower or a turbo-diesel V8 generating 555 pound-feet of torque (capable of towing over 12,000 pounds). The TITAN's various trim levels can turn this truck from a typical workhorse into a high-luxury vehicle.
