How many miles per gallon does a 2015 Ram diesel get?

The 2015 Ram diesel pickup truck is known for its impressive fuel efficiency, delivering up to 29 miles per gallon (mpg) on the highway. This makes the Ram diesel a popular choice among truck buyers who prioritize fuel economy without sacrificing the power and capability of a full-size pickup.


Factors Affecting the Ram Diesel's Fuel Economy


The fuel economy of the 2015 Ram diesel can vary depending on several factors, including the specific engine configuration, driving conditions, and driving habits. The Ram diesel is available with two different engine options: a 3.0-liter V6 EcoDiesel and a 6.7-liter Cummins inline-six turbodiesel.



  • Engine Configuration: The 3.0-liter EcoDiesel engine is rated at up to 29 mpg on the highway, while the 6.7-liter Cummins engine can achieve up to 28 mpg on the highway.

  • Driving Conditions: Fuel economy can be affected by factors such as terrain, weather, and traffic conditions. Driving in hilly or mountainous areas, for example, may result in lower fuel efficiency compared to flat, open roads.

  • Driving Habits: Aggressive acceleration, frequent braking, and high-speed driving can all contribute to lower fuel economy. Maintaining a consistent speed and avoiding sudden changes in throttle input can help maximize the Ram diesel's fuel efficiency.


It's important to note that the fuel economy figures provided by the manufacturer are based on EPA testing and may not reflect real-world driving conditions. Actual fuel economy may vary depending on the individual driver's habits and the specific driving environment.


Comparing the Ram Diesel to Other Diesel Trucks


When compared to other diesel-powered full-size trucks, the 2015 Ram diesel stands out for its impressive fuel economy. For example, the 2015 Ford F-150 diesel is rated at up to 27 mpg on the highway, while the 2015 Chevrolet Silverado diesel achieves up to 28 mpg on the highway.


The Ram diesel's fuel efficiency, combined with its powerful engine options and robust towing and hauling capabilities, make it a compelling choice for truck buyers who want a balance of performance and fuel economy.
