2020 Ram 1500 Rebel Diesel Fuel Efficiency: MPG Comparison With and Without a Trailer
2020 Ram 1500 EcoDiesel: Power, Efficiency, and Performance
Introduction to the 2020 Ram 1500 EcoDiesel
The 2020 Ram 1500 EcoDiesel marks a significant return for the 3.0-liter V-6 diesel engine, offering enhanced horsepower and torque. With 260 horsepower and 480 pounds-feet of torque, this engine is designed for those who prioritize fuel efficiency without sacrificing power. The EcoDiesel variant is particularly appealing for its impressive EPA-estimated fuel economy of 21/29/24 mpg city/highway/combined, making it a standout in the full-size truck segment.
Fuel Efficiency and Performance
One of the most compelling reasons to consider the Ram 1500 EcoDiesel is its fuel efficiency. Compared to its gas counterparts, the EcoDiesel offers superior mileage, especially on the highway. For instance, the Ram 1500 Rebel with the EcoDiesel engine achieves 21/29/24 mpg, outperforming the V-6 and V-8 gas engines, which return 19/24/21 mpg and 15/21/17 mpg, respectively.

- City MPG: 21
- Highway MPG: 29
- Combined MPG: 24
During a 107.2-mile test route, the Ram 1500 Rebel diesel demonstrated a calculated mileage of 25.7 mpg, closely matching the computer readout of 26.4 mpg. This efficiency translates to an impressive range of nearly 850 miles with the 33-gallon fuel tank, allowing for extended trips without frequent refueling stops.
Towing Capacity and Handling
The Ram 1500 EcoDiesel is not just about fuel efficiency; it also excels in towing capacity. With a maximum towing capacity of 9,750 pounds, this truck is well-suited for hauling heavy loads. During a test with a 5,000-pound travel trailer, the EcoDiesel returned a calculated mileage of 12.1 mpg, slightly lower than the computer's estimate of 13.2 mpg.

Despite the added weight, the EcoDiesel maintained strong performance, particularly on steep grades. The eight-speed transmission handled the load well, with only occasional downshifts required on the steepest climbs. However, the lack of an exhaust brake was noticeable during descents, where additional braking was necessary to manage the trailer's wind resistance.
Driving Experience and Comfort
The Ram 1500 EcoDiesel offers a comfortable and smooth driving experience, thanks in part to its four-corner air suspension. In Aero mode, the suspension lowers for improved aerodynamics, enhancing both fuel efficiency and ride comfort. This mode is automatically activated at sustained speeds above 62 mph, making it ideal for highway driving.

Off the line, the EcoDiesel exhibits a slower throttle response compared to gas engines, likely to reduce emissions. However, once underway, the truck maintains speed effortlessly, even on steep grades. The air suspension provides a supple ride, minimizing the harsh jolts often associated with full-size trucks.
Interior Features and Payload Capacity
The 2020 Ram 1500 EcoDiesel comes loaded with amenities, including the split tailgate, RamBoxes, and a fully equipped interior. However, these features add weight, reducing the payload capacity to just over 1,000 pounds. Despite this, the truck remains a versatile option for both daily driving and heavy-duty tasks.
The interior is designed with both comfort and functionality in mind, featuring an intuitive instrument panel and ample storage options. The crew-cab configuration provides plenty of space for passengers, making it a practical choice for families and professionals alike.

Is the EcoDiesel Worth the Investment?
Priced at $4,995 over the base V-6 and $3,500 more than the Hemi V-8, the EcoDiesel represents a significant investment. While the initial cost may be higher, the long-term benefits include superior fuel economy, extended range, and strong resale value. Diesel trucks traditionally command a premium in the used market, making the EcoDiesel a smart choice for those planning to sell or trade in the future.
For those who prioritize towing capacity and fuel efficiency, the EcoDiesel is an excellent option. Its combination of power, economy, and comfort makes it a standout in the competitive full-size truck market.
Conclusion
The 2020 Ram 1500 EcoDiesel is a powerful, efficient, and versatile truck that caters to a wide range of needs. Whether you're looking for a vehicle with exceptional fuel economy, strong towing capabilities, or a comfortable ride, the EcoDiesel delivers on all fronts. With its advanced features and impressive performance, it's no wonder the Ram 1500 EcoDiesel continues to be a top choice for truck enthusiasts.
