The Titan XD, intended to be a tweener model slotting into the gap between traditional half-ton pickups and heavy-duty models, initially was offered only with a 5.0-liter Cummins turbo-diesel V-8 from the Indiana-based engine supplier that is better known for providing diesel engines for semis and Ram pickups.
But more choice is always better in the pickup market (although the Titan XD remains Crew Cab only), and the Titan XD can’t hinge its entire lineup on the costly Cummins. Starting at $36,485—that’s $5000 less than the diesel V-8 version—the XD with a gasoline V-8 will also make its way into the more conventional half-ton Titan that goes on sale later this year.
True heavy-duty truck
Despite its lower mass, the gasoline-powered Titan XD fell short of its diesel sibling in skidpad and braking evaluations. Blame the Pro-4X’s off-road-oriented extras, especially the knobby General Grabber APT tires. The 205 feet it took for the gas XD to stop from 70 mph is more toward the realm of true heavy-duty trucks than light-duty ones. And the soft, vague feel of the brake pedal did not inspire confidence on the road.
