The 2016 Dodge Ram 2500 diesel represents a significant moment in the full-size truck segment, blending traditional gasoline power with the efficiency and torque advantages of a diesel powertrain. This model year marked a period of refinement for the Ram lineup, where the heavy-duty capability of the 2500 was paired with the 6.7-liter Cummins I6 engine, creating a truck built for serious work and long-distance hauling. For buyers needing to tow fifth wheels or haul substantial payloads, the diesel option was, and remains, a compelling choice that justified its premium over the standard Hemi V8.
Engineering the Power: The 6.7L Cummins I6
At the heart of the 2016 Ram 2500 diesel is the legendary 6.7-liter inline-six Cummins turbodiesel, a unit renowned for its durability and massive low-end torque. Producing 370 pound-feet of torque and 310 horsepower, this engine was specifically designed for the American market to meet emissions regulations without sacrificing the capability that diesel buyers expect. The power is delivered through a robust six-speed automatic transmission, which manages the substantial grunt and provides confident acceleration, especially when pulling a trailer or navigating steep grades.
Towing and Payload Capacity
One of the primary reasons drivers opt for the 2500 diesel is its staggering towing capacity. The 2016 model year could tow up to 17,980 pounds when properly equipped, making it one of the strongest contenders in the half-ton to one-ton truck segment. This capability is supported by a heavy-duty towing package that includes a robust transmission cooler, auxiliary transmission fluid cooler, and a heavy-duty radiator, ensuring the engine and transmission remain cool under the most strenuous conditions.
On-Road Comfort and Daily Driveability
Beyond its work-focused credentials, the 2016 Ram 2500 diesel offers a surprisingly civilized driving experience for a heavy-duty truck. The Cummins engine is notably quiet and smooth, with minimal vibration compared to its gasoline counterparts. This refinement translates to a more pleasant daily commute, reducing driver fatigue on long highway stretches while still providing the commanding view and presence that defines the Ram design language.
Interior Quality and Modern Features
Inside, the 2016 Ram 2500 benefited from the Uconnect infotainment system, which provided a responsive touchscreen interface and modern connectivity options. The cabin materials were upgraded from previous generations, with more soft-touch plastics and available premium leather seating contributing to a higher overall quality feel. Drivers appreciated the thoughtful layout of the dashboard, which placed essential controls within easy reach without feeling cluttered, even with the diesel-specific gauges sometimes included.
Fuel Economy and Real-World Efficiency
While not class-leading, the fuel economy of the 2016 Ram 2500 diesel was competitive for its segment and a significant improvement over the larger displacement gasoline V8s. When configured with the efficient 6-speed automatic transmission, this truck could achieve an estimated 19 MPG in combined driving for the standard box configuration. Owners who regularly tow heavy loads will find the diesel’s efficiency particularly advantageous, as the engine operates at lower RPMs during highway cruising, translating to fewer fill-ups over the life of ownership.
Payload Capacity and Capability
The 2500 designation is not just about towing; it also signifies a robust payload capacity. The truck’s sturdy frame, combined with its available heavy-duty suspension, allowed for a maximum payload of approximately 3,100 pounds. This makes the 2016 model suitable for contractors hauling equipment, farmers transporting supplies, or anyone who needs to move heavy materials regularly. The combination of a capable diesel engine and a strong chassis ensures that the truck performs as expected when the bed is full.
