What is the gas mileage on a Ram 2500 5.7 Hemi?
In general, a Ram 2500 with the 5.7-liter Hemi delivers mileage in the mid-teens in city driving and the low-to-mid-20s on the highway. Two-wheel-drive versions typically post higher highway numbers than four-wheel-drive models, and exact figures vary by model year, axle ratio, payload, and towing. For precise estimates, check the EPA ratings for your specific year and configuration on fueleconomy.gov.
EPA estimates by drivetrain
The following ranges reflect recent Ram 2500 models equipped with the 5.7 Hemi and an 8-speed automatic. Real-world results can differ based on payload, towing, and driving conditions.
Two-wheel drive (2WD) Ram 2500 with 5.7 Hemi
- EPA city mpg: approximately 15–16 mpg
- EPA highway mpg: approximately 21–23 mpg
- EPA combined mpg: approximately 18–19 mpg
Note: Actual mileage can vary widely with payload, towing, road grade, and driving style. Use EPA numbers as a baseline, then consider your typical use case.
Four-wheel drive (4WD) Ram 2500 with 5.7 Hemi
- EPA city mpg: approximately 14–15 mpg
- EPA highway mpg: approximately 19–21 mpg
- EPA combined mpg: approximately 17–18 mpg
In daily use, 4WD models tend to be a bit less economical than 2WD, especially when carrying payload or towing, due to increased drivetrain mechanical losses and weight.
Real-world mpg considerations
EPA ratings provide a standardized baseline, but real-world fuel economy depends on several factors. Heavier payloads and towing loads, frequent stops, and hilly terrain typically reduce mpg. Steady highway cruising at moderate speeds, proper tire inflation, and regular maintenance can help maximize efficiency. Conversely, aggressive acceleration, extended idling, and ineffective aerodynamics (such as roof racks or open windows at speed) can lower fuel economy.
For those planning a purchase or a long-term ownership, it’s wise to review model-year-specific EPA data and consider your typical use case—daily commuting, frequent towing, or mixed driving—to gauge what kind of mileage you can expect from a Ram 2500 with a 5.7 Hemi.
Summary
Across recent model years, a 2WD Ram 2500 with the 5.7 Hemi generally sits around 15–16 mpg in the city and 21–23 mpg on the highway (combined roughly 18–19 mpg). A 4WD version typically averages about 14–15 mpg city and 19–21 mpg highway (combined around 17–18 mpg). Real-world results will vary with payload, towing, terrain, and driving habits. Always verify the exact EPA rating for your specific year and configuration on fueleconomy.gov.
