What is the gas mileage on a 6.7 Hemi Ram 2500?

The 6.7-liter Hemi V8 engine in the Ram 2500 heavy-duty pickup truck delivers impressive power, but how does it perform when it comes to fuel efficiency? Let's take a closer look at the gas mileage you can expect from this powerful truck.


Fuel Economy Ratings for the 6.7 Hemi Ram 2500


According to the Environmental Protection Agency (EPA), the 2023 Ram 2500 with the 6.7-liter Hemi V8 engine has the following fuel economy ratings:



  • 2WD models: 16 mpg city, 22 mpg highway, 18 mpg combined

  • 4WD models: 15 mpg city, 21 mpg highway, 17 mpg combined


These figures are based on the EPA's standard testing procedures, which simulate real-world driving conditions. However, your actual fuel economy may vary depending on factors such as driving style, terrain, weather, and vehicle load.


Factors Affecting Fuel Efficiency


The 6.7 Hemi engine in the Ram 2500 is a powerful workhorse, designed to handle heavy-duty tasks like towing and hauling. As a result, its fuel efficiency may be lower than that of lighter-duty trucks or SUVs. Some key factors that can impact the fuel economy of the 6.7 Hemi Ram 2500 include:



  • Engine size and power: The 6.7-liter Hemi V8 engine produces 370 horsepower and 850 lb-ft of torque, which requires more fuel to operate than smaller, less powerful engines.

  • Drivetrain configuration: 4WD models typically have slightly lower fuel efficiency than 2WD models due to the additional drivetrain components and weight.

  • Driving conditions: Towing heavy loads, driving in hilly terrain, or frequent stop-and-go traffic can all reduce the truck's fuel economy.

  • Maintenance and driving habits: Proper vehicle maintenance, such as keeping tires properly inflated, and driving at moderate speeds can help maximize fuel efficiency.


It's important to note that the 6.7 Hemi Ram 2500 is designed for heavy-duty work, and its fuel efficiency may not be the primary concern for many buyers in this segment. The truck's impressive power and capability are often the top priorities.
