The Nissan Titan XD is a full-size pickup truck that was introduced for the 2016 model year. It is available in both two-wheel and four-wheel drive configurations, and is offered in both gasoline and diesel engine options. The Titan XD is designed to bridge the gap between lightweight, half-ton pickups and heavy-duty, three-quarter ton trucks, offering better towing and payload capability than a standard full-size pickup without requiring the heavier diesel engine or suspension components of a three-quarter ton model.
