2018 Nissan Titan XD Pro-4X Diesel Proves Its Towing, Off-Road Chops

Towing 1 II

After diving into what's makes the 2018 Nissan Titan XD special in part one of our Titan XD series, the second part will focus on how the diesel-powered crew-cab Pro-4X performed when towing and going off-road during a trip to Moab, Utah.

How It Tows

Hooking the 2018 Nissan Titan XD to our 5,000-pound travel trailer was a breeze because of its backup monitor with trailer guides. One thing we noticed right away was that the sideview mirrors didn't extend far enough to easily see down the sides of the trailer. They only needed to be an extra inch wider. The truck also had the trailer light check system, which was useful when checking the lights solo: Simply start the test with a tap on the multimedia screen and walk to the back of the trailer. The truck will honk indicating that it is beginning the light check. You can then visually check the lights as it goes through each turn signal and brakelight; the truck will honk again when the test is finished.

Having 600 pounds on the tongue of the trailer hitch smoothed out the ride a little bit, as is expected in most pickup trucks. Despite tow ratings (maximum of 12,030 pounds) that are not much higher than most half-ton trucks — and the 2018 Ford F-150 can be optioned for 13,200 pounds — the XD clearly outperforms them in stability and pulling power. It provided a more secure feeling while towing by controlling the load well and having both the torque and braking power needed for confident towing.

The additional low-end torque and exhaust control of the diesel engine also help with accelerating and stopping. Nissan doesn't state the XD has an exhaust brake, but the turbo definitely provides a good amount of back pressure with Tow/Haul engaged.

We never experienced any trailer sway or the trailer pushing the truck around during our towing tests. The fuel mileage was lower than expected with a 9.8 mpg average over 452 miles of straight towing. Most of that towing was on open highways with speeds around 70 mph. We've towed this same trailer with a 2018 Ram 2500 with the Cummins and averaged more than 12 mpg. Adding to our mileage frustration with the Titan XD was its minuscule 26-gallon fuel tank that provided about 250 miles of range. Looking under the truck, there is plenty of empty space ahead of the fuel tank that could have accommodated a larger tank, increasing capacity by another 5 or so gallons.

How It Handles Off-Road

The 2018 Nissan Titan Pro-4X comes with Bilstein shocks, 32-inch A/T General Grabber APT tires, a full set of strong skid plates and wheels that are unique from the rest of the XD lineup. Moab is known for its off-road trails, so we were excited to drive some of the famous red-rock trails we've been reading about for years. We started with Baby Lion's Back and then sampled the first portion of Fins and Things, two trails that have done quite a bit of damage to smaller, less capable pickups and SUVs. Stock full-size pickups are not commonly seen running these trails, but that didn't stop us. We aired the tires down to 30 pounds per square inch and headed for the hills.

Running the 30-degree slopes of Baby Lion's Back was a breeze in the Titan XD, even with an old trailer hitch sticking out of the receiver to prevent the bumper from dragging. However, there wasn't a single time where anything hit the slickrock. We also learned that the Titan XD's surround view camera does a good job of showing where the truck is but provides poor depth perception. If the driver got out and mapped a line, the cameras could be used to stick to that line. The cameras weren't much help in finding the best line as they didn't provide enough clarity. At 20.18 degrees, the approach angle on the Pro-4X is much lower than the approach angles of competitors' off-road-oriented trucks.

Although possibly an unfair comparison, the Ram 2500 Power Wagon has an approach angle of 33.6 degrees; the Toyota Tundra TRD Pro, 31 degrees; and the Ford F-150 Raptor, 30 degrees. This quickly became apparent on Fins and Things. Luckily the first contact point on the front end was the tow hook, which can handle taking hard hits. Even with the poor approach and departure angles of the Titan XD Pro-4X, it handled this trail quite well. There were a few times when the front skid plate was a life saver, and the hitch in the rear dragged on three or four obstacles as well. Picking good lines and angling the approaches and departures off the obstacles kept us from getting stuck or damaging the vehicle.
