The new Titan is a handsome truck, with lots of chrome up front and muscular fenders. The new design offers better aerodynamics, with a front spoiler, roof and tailgate spoilers, underbody airflow covers, and other features for less wind resistance than the pre-2016 models presented.
Though the Titan and Titan XD look the same, the XD is substantially larger and they share few body panels. The XD is taller by about 1.5 inches, most noticeable by the height of the hood. And it's longer, by nearly 15 inches overall and nearly 12 inches in wheelbase, when Crew Cab versions are compared. The two trucks are the same width.
Specifically, the Titan Crew Cab is built on a 139.8-inch wheelbase and is 228.1 inches long, 77.2 inches tall, 79.5 inches wide. The Titan XD Crew Cab is built on a 151.6-inch wheelbase and is 242.7 inches long, 78.0 inches tall, 79.5 inches wide.
The Titan's styling makes it look smaller than its actual dimensions, so it's easy to think of it being smaller than the Fords, GMs and Dodges until it's parked alongside of one of them. Then, it seems to grow in size, slightly exceeding the other trucks in actual dimensions.
For example, a comparable Ram 2500 crew cab with a 6-foot-4 bed rides on a 149.5-inch wheelbase and measures 237.4 inches overall, 73.7 inches tall for 4x2, 77.7 inches for 4x4, 79.1 inches wide. Silverado 2500 Crew Cab with 6-foot-6 box is on a 153.7-inch wheelbase, stretches 239.4 inches in length 78.3 inches tall, and 80.5 inches wide.
