The 2019 Ram 1500 diesel represents a significant evolution in the full-size pickup segment, specifically targeting buyers who prioritize efficiency and towing capacity without sacrificing capability. This model year marked a turning point for the Ram brand, introducing a refined powertrain that combined robust performance with surprisingly frugal fuel economy. Unlike its gasoline-guzzling counterparts, this diesel variant was engineered to handle heavy-duty tasks while keeping operational costs in check. The result is a truck that feels modern, capable, and thoughtfully calibrated for both work and weekend use.
Engineering the Power: The 6.7L Cummins Turbo Diesel
At the heart of the 2019 Ram 1500 diesel is the legendary 6.7-liter inline-six Cummins turbodiesel engine, a unit renowned for its durability and low-end grunt. Producing 370 pound-feet of torque and 260 horsepower, this powerplant was specifically chosen to excel where gasoline engines struggle: towing and hauling. The immense torque curve delivered from low RPMs allows the truck to pull heavy trailers with remarkable ease, making it a favorite among contractors and recreational haulers alike. The engineering focus here was not just on power, but on the seamless integration of this diesel heart into the Ram’s sophisticated platform.
Fuel Economy and Real-World Efficiency
One of the most compelling arguments for the 2019 Ram 1500 diesel is its fuel efficiency, a rare trait in the full-size truck class. While official EPA ratings placed it in the mid-20s for highway MPG, real-world usage often showed even better results, particularly when towing or during steady-state cruising. This efficiency stems from the diesel cycle itself, which extracts more energy from each gallon of fuel compared to traditional gasoline combustion. For drivers who log significant miles or frequently tow, the premium price of the diesel option is often offset by the substantial savings at the pump over the life of the vehicle.
Capabilities and Towing Performance
Beyond the numbers, the 2019 Ram 1500 diesel delivers on its promise of capability. The diesel engine’s robust torque translates to a maximum towing capacity of up to 12,750 pounds and a payload capacity of around 2,080 pounds, depending on configuration and axle ratio. This makes it competitive with the toughest rivals in the segment, such as the Ford F-150 Power Stroke and the Chevrolet Silverado Duramax. The transmission, a capable eight-speed automatic, was tuned to hold low gears for extended periods without overheating, ensuring consistent performance during long descents or heavy towing sessions.
Refinement and On-Road Dynamics
Contrary to the notion that diesel trucks are noisy and jarring, the 2019 Ram 1500 diesel offers a refined driving experience. The integration of the diesel engine with the smooth-shifting eight-speed transmission results in a quiet and composed cabin, especially during highway driving. Road noise is well-controlled, and the diesel’s vibrations are minimal, making daily drives comfortable. The steering feels precise, and the chassis handles bumps with a composure that surprises in a truck of this stature, blending workhorse credentials with everyday usability.
Interior Comfort and Modern Technology
Ram did not skimp on the interior of the 2019 model, ensuring the diesel variant felt like a premium product. The cabin was spacious, with supportive seats and high-quality materials that invited long-distance comfort. Advanced technology was also a priority, with the available Uconnect system providing intuitive access to navigation, entertainment, and vehicle settings. Features like blind-spot monitoring, rear cross-path detection, and adaptive cruise control were often bundled into the diesel-exclusive or available technology packages, enhancing both safety and convenience for the modern driver.
