The 2014 Ram diesel represents a significant moment in the evolution of light-duty trucks, marking the introduction of a new era for the Ram lineup. This specific model year was the debut for the legendary 6.7-liter Cummins turbodiesel engine in the Ram 1500, a powertrain that would go on to define the segment. For years, diesel power in a half-ton pickup was a niche proposition, but Ram aimed to change that with a unit that promised impressive torque and capability without sacrificing daily usability.
Engineering the 6.7L Cummins
At the heart of the 2014 Ram 1500 diesel is the 6.7-liter inline-six Cummins ISB. This was not a lightly engineered option; it was a meticulously developed partnership between Ram and Cummins. The engine was designed specifically with the unique demands of a light-duty truck in mind, focusing on low-end torque and reliability. Key features included a larger turbocharger, an air-to-air intercooler, and advanced fuel injection technology that helped it produce 310 horsepower and 610 lb-ft of torque. This torque figure was revolutionary for the segment, providing a level of pulling power that made towing and hauling effortless.
Capabilities and Real-World Performance
Power numbers only tell part of the story, and the true measure of the 2014 Ram diesel is its capability in the field. With the available eTorque mild-hybrid system, which used a belt-driven integrated starter/generator, the truck could assist the engine during takeoff and provide electrical power for accessories. The diesel configuration came with a robust towing package, including a class-VI trailer hitch and enhanced cooling systems. Owners consistently reported effortless towing of fifth-wheel trailers and boats, with the engine maintaining composure even on long grades where gasoline engines would struggle and overheat.
Interior Comfort and Daily Driving
One of the most impressive aspects of the 2014 Ram diesel is how well it balanced capability with comfort. Unlike some work-focused competitors, the Ram 1500 offered a refined and quiet cabin. The diesel engine, while powerful, was surprisingly subdued for a work truck, with noise, vibration, and harshness (NVH) carefully managed. The interior was a sanctuary, featuring premium materials, available leather seating, and the legendary Uconnect infotainment system. This focus on comfort meant the truck was just as at home on a commute as it was on a job site, making it a true all-rounder rather than a dedicated workhorse.
Fuel Economy and Efficiency
Fuel efficiency is often a concern with diesel trucks, but the 2014 Ram 1500 managed to exceed expectations. Thanks to the efficient combustion cycle of the Cummins engine and the stop-start capabilities of the eTorque system, the truck delivered respectable numbers. While actual mileage varies based on driving style and towing habits, many drivers found they were getting in the low 20s MPG on the highway when not towing. This efficiency, combined with the low-end torque of diesel fuel, translated to lower cost-per-mile ownership for those who utilized the truck heavily, effectively turning each gallon of fuel into more work.
Design and Practicality
The exterior of the 2014 Ram 1500 was a blend of aggressive purpose and aerodynamic efficiency. The bold grille and muscular fenders signaled its capability, while the optional front air dam and integrated trailer sway control enhanced its function. Inside, the design was user-centric, with easy-to-grab door handles, clear sightlines, and a layout that put critical controls within reach. The available rear-seat fold-flat configuration expanded the cargo bed’s versatility, allowing for the hauling of long materials or large items that wouldn't normally fit in a standard pickup box. This thoughtful design ensured that the truck was as practical as it was powerful.
