2018 Nissan Titan XD Pro-4X: Living With Nissan's Diesel 'In-Betweener'
The 2018 Nissan Titan XD Pro-4X occupies a unique space in the truck market - more capable than half-ton pickups but more manageable than heavy-duty three-quarter-ton models. We spent a week testing this Cummins diesel-powered workhorse in both daily driving and off-road conditions to see if its 'in-betweener' positioning makes practical sense

Powertrain: Cummins Diesel Performance
The Titan XD's standout feature is its 5.0L Cummins turbo-diesel V8:
| Specification | 5.0L Cummins V8 Turbo-Diesel |
|---|---|
| Horsepower | 310 @ 3,200 rpm |
| Torque | 555 lb-ft @ 1,600 rpm |
| Transmission | 6-speed automatic |
| Max Towing | 12,310 lbs (gooseneck) |
| Max Payload | 2,090 lbs |
Driving Impressions
The Cummins diesel delivers characteristic low-end torque that makes towing feel effortless. While not a speed demon (0-60 mph in ~8 seconds), there's always power on tap for merging or climbing grades. The 6-speed transmission shifts smoothly but could benefit from additional gears like competitors' 8- and 10-speed units.
Interior: Spacious Cabin With Thoughtful Touches
The Titan XD's interior stands out for its generous space and practical features:
Comfort & Convenience
- Best-in-class front headroom (43.1") and legroom (41.8")
- Heated/cooled leather seats (Premium Package)
- Heated steering wheel
- Dual-zone automatic climate control
- Ample storage including dual-tier seatback pockets
Technology Features
- 8" touchscreen with navigation
- 360-degree camera system
- 13-speaker Rockford Fosgate audio
- 120V power outlets (cabin and bed)
- Blind spot monitoring with trailer coverage
Notable Omission: The Pro-4X's carpeted floor mats seem out of place in an off-road package. All-weather rubber mats should be standard or at least a no-cost option.

Exterior & Utility Features
The Titan XD's imposing presence comes with functional advantages:
Pro-4X Off-Road Package
- Bilstein off-road shocks
- Electronic locking rear differential
- Skid plates (engine, fuel tank, transfer case)
- 18" alloy wheels with all-terrain tires
- Unique exterior badging and styling
Utility Features
- Integrated gooseneck hitch prep
- Lockable bedside storage boxes
- LED bed lighting (Utility Package)
- Rear step bumper
- Power locking tailgate
The 360-degree camera system proves invaluable when maneuvering this large truck in tight spaces. The standard running boards would benefit from being slightly wider for easier entry/exit.
Daily Driving Experience
Living with the Titan XD reveals both strengths and compromises:
Real-World Observations
- Visibility: Commanding view of the road with minimal blind spots
- Maneuverability: 47.8' turning radius requires planning in tight spaces
- Ride Quality: Firmer than half-tons but smoother than 3/4-ton trucks
- Fuel Economy: 16.7 mpg observed (15 city/20 highway EPA estimate)
- Noise Levels: Noticeable diesel clatter at idle but quiet at speed
The Titan XD's size becomes most apparent in urban environments. While the cameras help, parking this 20.8' long truck requires adjustment for those accustomed to smaller pickups.
Diesel Maintenance Considerations
The Cummins diesel adds some maintenance requirements but Nissan makes them manageable:
--SECOND CAR LIST HERE--
| Maintenance Item | Interval | Accessibility |
|---|---|---|
| Fuel filter replacement | Every 15,000 miles | Easy (top of engine) |
| Diesel exhaust fluid (DEF) refill | Every 5,000-7,000 miles | Next to fuel filler |
| Water separator drain | Every oil change | Tool-free (under truck) |
| Oil changes | Every 7,500 miles | Conventional placement |
DEF consumption averaged approximately 1 gallon per 500 miles in mixed driving. The 8-gallon DEF tank means refills align with typical service intervals.

Competitive Landscape: How It Stacks Up
The Titan XD's unique positioning becomes clear when compared to rivals:
| Model | Base Price | Max Tow (lbs) | Payload (lbs) | MPG (city/hwy) |
|---|---|---|---|---|
| Nissan Titan XD Diesel | $43,340 | 12,310 | 2,090 | 15/20 |
| Ford F-150 3.5L EcoBoost | $38,750 | 13,200 | 3,270 | 17/23 |
| Ram 1500 3.0L EcoDiesel | $41,340 | 12,560 | 1,970 | 20/27 |
| Chevrolet Silverado 2500 Diesel | $46,100 | 18,100 | 3,979 | 14/18 |
The Titan XD slots neatly between half-ton and heavy-duty trucks in both capability and pricing, though fuel economy trails newer diesel competitors.
