Standard half-ton pickup or heavy-duty variant? That’s the question often faced by those needing a pickup for commercial use, combined personal/business activity, or heavy-duty towing. It’s a tough choice because heavy-duty pickups really do offer levels of functionality that typically exceed that of light-duty pickups, but they’re also costlier, more cumbersome to maneuver, and usually less fuel efficient.

Nissan’s fully-redesigned Titan XD aims to solve this conundrum by combining the capability of a heavy-duty pickup with the fuel economy and affordability of a half-ton model. It delivers welcome functionality with a 5.6-liter Endurance gasoline V-8 or a notable 5.0-liter Cummins turbodiesel that delivers 310 horsepower and a formidable 555 lb-ft torque. The latter is capable of carrying a 2,000 pound payload or towing up to 12,000 pounds.

A half-ton 2017 Titan variant introduced just this summer shares the Titan DNA but is distinguished by a unique chassis some 14.7 inches shorter than that of the XD. No diesel powerplant is offered with the lighter-duty Titan, which is powered by the same 390 horsepower, 5.6-liter Endurance gasoline V-8 and connected to a seven-speed automatic transmission. An as-yet undisclosed V-6 will also be available for the half-ton Titan.

Titan XD benefits from the first application of the new Cummins M2 two-stage turbo system, which helps reduce turbo lag through precision balancing between high-pressure and low-pressure turbos. The engine’s Rotary Turbine Control provides solid performance across the powerband and manages exhaust gas temperatures. Efficiency-enhancing weight reduction is achieved with a compacted graphite iron cylinder block, high-strength aluminum alloy heads, and composite valve covers. The CGI block, along with the dual overhead camshafts, contributes to Nissan’s goal of delivering excellent noise, vibration, and harshness characteristics.

The XD features an extended 151.6-inch wheelbase to handle the higher towing and payload potential of the Cummins diesel while maximizing stability, handling, and ride comfort. It also uses a new heavy-duty, highly stable suspension design. Titan XD buyers can choose between several available hitches including an integrated gooseneck hitch engineered into the frame that’s easily accessible in the bed. It is also snow plow-capable.

Clearly, the Titan XD is the right size pickup for many chores. Nowhere is this more evident than when it comes to overall driveability. The step up to a traditional heavy-duty pickup is more than many drivers care to deal with on a daily basis. Titan XD simply doesn’t feel as cumbersome as a bigger and heavier HD truck. We wouldn’t call it nimble, but it is certainly easier to maneuver, especially around town. Overall ride and handling is quite pleasant and on par with most half-ton pickups. We drove the Titan XD loaded near maximum payload capacity and it performed without complaint.

The Titan XD is offered in Crew Cab, King Cab, and Single Cab versions with three available bed lengths. A work truck version is also available. All are mated to a six-speed automatic transmission. The Titan XD is offered in several trims including a rugged-looking Pro-4X model and a top-of-the-line Platinum Reserve. All except the Pro-4X can be had with two- or four-wheel drive. Inside, The Titan XD’s instrument panel integrates both analog and digital gauges and a 5-inch color display, plus diesel monitoring and maintenance displays. A 7-inch color monitor includes NissanConnect with navigation, mobile apps, and service.

While fuel economy estimates are not required for heavy-duty pickup models, expect the XD's Cummins diesel to provide about 20 percent better efficiency than a gas-powered V-8 while towing full loads. Our driving experience in an XD with a fully-loaded pickup bed realized a mpg average of just over 20 mpg…pretty impressive for an HD pickup.

Diesel haters seem to be overly anxious to pile-on and shout ‘death to diesels’ these days. It’s human nature to take offense at being fooled and the diesel market certainly is paying the price of the recent emissions scandal. Serious deception took place and it’s far from forgotten, even as corrections are underway or being explored. The green car market is very competitive so it’s not surprising that some supporting alternative transportation technologies are quick to point the finger.

Allen Schaeffer, Executive Director of the Diesel Technology Forum, responded to a story entitled “The Dirty Truth About Clean Diesel” in The New York Times with the following statement, which the Times ran in its Opinion pages. “Here are the facts about diesel straight from the Environmental Protection Agency and California Air Resources Board: Clean diesel technology and fuels have reduced particulate matter and nitrogen oxide emissions by more than 98 percent, and sulfur content by 97 percent. The American Lung Association cites clean diesel fleets as one of the two primary reasons for improved air quality in the United States.”

Personally, I’ve owned a diesel powered Ford pickup for many years and its overall capability and economy are simply hard to replace. Consider that nearly every product we touch on a daily basis – from the food on our table to the consumer products we all rely on – are harvested and/or transported by diesel powered trucks, trains, and ships. Diesel is an important part of our infrastructure and without it the cost of all goods and services would certainly increase.

I don’t mind admitting I’m still a fan of advanced diesel. I find it discouraging that just as smaller next-generation diesel passenger vehicles were gaining momentum in the North American market, this distrust has many questioning diesel’s place in the automotive landscape. As far as the driving experience goes, it is tough to beat the satisfying torque that a modern diesel delivers. When combined with advanced transmissions they are quite fun to drive.

With EPA federal rules requiring significantly better fuel economy and lower CO2 emissions by 2025, next-generation diesel should be a key player in achieving these goals. A primary advantage of diesel has always been superior fuel economy. A diesel will generally deliver 30 percent higher fuel economy than a comparable gasoline model. That huge bump in mileage also brings a significant decrease in CO2 emissions.

Plus, it’s important to note that the more advanced diesels on the road, the greater the potential use of even cleaner-burning biodiesel, a renewable diesel fuel replacement that has experienced significant growth over the past decade.

The road back to diesel acceptance will likely come first in the light truck and sport utility vehicle market with more light-duty diesel pickups and luxury SUVs moving forward. Good examples are the recent introduction of the 5.0-liter V-8 Cummins turbo diesel in the new Nissan Titan and 2.8-liter Duramax four-cylinder turbo diesel in the mid-size Chevy Colorado and GMC Canyon. Want something a little more exotic? Land Rover and Range Rover are now offering models with their Td6 next-generation diesel, with other automakers also introducing newer, more efficient, and cleaner diesel models as well.

We hope to see lower-priced, high mileage next-generation diesel models in the near future to fill the void in the small car market.

It’s well understood that Ford’s EcoBoost engines combine direct injection, variable valve timing, and turbocharging to achieve impressive power and high efficiency. While these advanced engines deliver the acceleration and high fuel economy desired in mainstream models, EcoBoost engines also power the automaker’s performance-oriented models like the Mustang and Fiesta ST. As die-hard enthusiasts always wonder…is there a way to eke even more performance from my car?

And the answer is ‘yes,’ with new hand-held programmers from Ford that adjust a multitude of engine parameters. Tuners often go the traditional route of replacing original equipment with aftermarket parts like performance camshafts, exhaust and intake manifolds, high-flow fueling systems, and even superchargers, sometimes with unwanted trade-offs in efficiency, durability, or comfort.

Ford points out that in an age of computer-controlled engines, a better answer is performance mods using Ford Racing’s programming handset. The $595 ProCal programmer for the Focus ST 2.0-liter EcoBoost engine and Fiesta ST 1.6-liter EcoBoost plugs into the car’s diagnostic link connector port, enabling performance tweaks to everything from throttle response characteristics and idle speed to turbo wastegate control, fuel curves, and spark timing.

In the hands of engine tuning experts, tweaking with the ProCal can bring impressive gains in horsepower and torque output. The Focus ST can gain up to a 90 lb-ft torque increase while maintaining the Ford-backed limited warranty. Custom engine calibrations for the all-new Mustang 2.3-liter EcoBoost are being developed by Ford Racing with a product expected by the end of 2015.
