Short answer: The Dodge Durango R/T (with the 5.7L HEMI V8) is EPA-rated about 17 combined MPG (roughly 14 city / 22 highway) for AWD/RWD R/T configurations and real-world owner averages typically fall in the 14-18 MPG range depending on driving mix and tuning.
Key fuel figures
The 5.7L HEMI V8 is the factory engine for the Durango R/T and is officially EPA-rated at approximately 14 city / 22 highway / 17 combined MPG for the 2022-2025 model years in AWD and RWD configurations, depending on package and final gearing.
- EPA combined estimate: ~17 MPG for the R/T 5.7L HEMI.
- Typical owner averages: 14-18 MPG observed across user reports and fleet tracking.
- Highway potential: In steady highway drives some R/T owners and tests report up to ~22-23 MPG.
- City driving: City averages commonly fall to low-to-mid teens (~12-15 MPG) under normal use.
Detailed table - fuel specs and practical numbers
| Specification | Value | Source / Notes |
|---|---|---|
| Engine | 5.7L HEMI V8 | R/T standard V8; HEMI with VVT and cylinder deactivation. |
| EPA City | 14 MPG | EPA published figure for 5.7L Durango (example year: 2022). |
| EPA Highway | 22 MPG | EPA published highway rating for 5.7L Durango. |
| EPA Combined | 17 MPG | Manufacturer/EPA combined estimate for 5.7L R/T. |
| Real-world fleet avg | 15.4 MPG (Fuelly aggregated average across many R/Ts) | Aggregated owner data through 2024-2025; sample size varies. |
| Fuel tank | ~24.6 gallons (typical Durango tank) | Enables highway ranges ~540-570 miles depending on trim and drive cycle (tested ranges). |
Why factory numbers and owner reality differ
EPA ratings are produced under standardized test cycles and assume idealized conditions; real-world owner averages reflect weather, towing, grade, payload, tire choice, pump octane, and driver behavior, which commonly reduce combined MPG by several points.
- Driving mix matters: City stop-start driving lowers MPG relative to highway cruising.
- Weight and load: Higher payload, roof racks, and towing quickly drop fuel economy.
- Fuel & tuning: Some owners report better throttle response and different fuel use with higher-octane fuel or aftermarket tunes, altering consumption.
Historical context and test results
The Durango's V8 option historically positions it as a performance-oriented three-row SUV rather than a fuel-efficiency leader; publications and independent tests from 2017-2019 showed the V8 R/T sometimes matched or even slightly outperformed EPA highway ratings, with a 2018 R/T returning about 23 MPG on a 200-mile highway loop in a controlled test.
Conversely, aggregated owner telemetry through 2023-2025 shows a large spread in averages - some vehicles report high-teens MPG on mixed driving while urban owners often report low-teens, highlighting the variance between controlled tests and daily use.
Practical tips to improve MPG
Small adjustments to driving and vehicle setup can yield measurable gains in a Durango R/T; owners routinely cite a 5-15% improvement with combined changes.
- Maintain correct tire pressure - running tires at manufacturer-specified PSI reduces rolling resistance and improves MPG.
- Use ECO mode when available - it optimizes shift points and throttle mapping to save fuel.
- Use proper octane only when required - the 5.7L typically runs on regular, saving pump cost compared with premium-only engines.
- Reduce excess weight and drag - remove unused roof racks and clear cargo to improve economy.
Common owner-reported ranges
Aggregated owner reports and forum posts produce these practical, experience-driven ranges for the R/T 5.7L: 10-12 MPG in heavy city/tow scenarios, 14-18 MPG in typical mixed driving, and occasional 22-23 MPG sustained on long highway runs.
Quote from owners and testing
"On long trips I've averaged about 22 MPG and day-to-day about 16 or so," reported one Durango R/T owner in a 2023 thread summarizing several owners' experience.
Quick comparison (Durango trims - illustrative)
| Trim | Engine | EPA Combined (est.) | Typical real-world |
|---|---|---|---|
| Durango SXT/GT | 3.6L V6 | 21 MPG | 19-24 MPG mixed/highway. |
| Durango R/T | 5.7L HEMI V8 | 17 MPG | 14-18 MPG typical; 22-23 MPG highway possible. |
| Durango SRT / Hellcat | 6.4L / 6.2L Supercharged | 13-15 MPG | 9-17 MPG depending on use and model. |
Buyers' checklist if fuel economy matters
- Decide priorities: If family hauling and towing matter more than fuel economy, the R/T is appropriate; otherwise consider a V6 Durango or a competitor with smaller turbo engines.
- Review EPA figures: Compare the published EPA city/highway/combined numbers for the specific model year you're buying.
- Check owner data: Browse owner logs (Fuelly, forums) for real-world averages of the exact year and drivetrain you plan to buy.
- Factor in fuel type: Confirm whether your chosen engine requires premium; most R/T 5.7L models run on regular.
FAQ
Data sources and further reading
EPA model pages, aggregated owner databases, manufacturer spec sheets, and independent highway tests provide the underlying MPG figures and owner-reported ranges cited above.
What are the most common questions about Dodge Durango Rt Fuel Efficiency Specs?
What causes 2-6 MPG swings?
Temperature, tire compound, transmission tune, and altitude each shift mileage; for example, a 2018 highway test showed the R/T V8 exceeded EPA highway by 1 mpg under ideal cruise conditions, showing how narrow margins can flip expected results.
Is the Durango R/T a "gas guzzler"?
The Durango R/T is a mid-size SUV with a V8; it consumes more fuel than small crossovers but is not unusually wasteful for its class and performance level - whether it's a "gas guzzler" depends on buyer priorities and expected use.
How do EPA test numbers compare?
EPA test numbers provide a baseline; owners should expect a spread around those numbers with many real-world averages slightly lower than EPA combined figures but sometimes higher on long steady highway routes.
How to estimate annual fuel cost?
Estimate annual fuel cost by multiplying yearly miles by 1 / (expected MPG) and by local fuel price; for example, at 12,000 miles/year and 17 MPG with $3.75/gal fuel, expected annual fuel spend ≈ (12,000/17)*3.75 ≈ $2,647 per year.
How much range can I expect?
With a ~24.6 gallon tank and real-world combined MPG near 17, expect a practical driving range of roughly 400-420 miles between fills in mixed driving; highway-only cruising can extend that toward ~540-570 miles under ideal conditions.
Are aftermarket tunes and modifications worth it?
Aftermarket tuning can raise horsepower but often increases fuel consumption; some owners trade a small MPG loss for performance gains, while others tune for efficiency and see incremental improvements - results vary and voiding warranties is a risk.
What is the EPA MPG for the Durango R/T?
The EPA lists the 5.7L Durango R/T at about 14 city / 22 highway / 17 combined for model years around 2022-2024, with small variations by drivetrain and year.
What MPG do owners actually get?
Owners typically report 14-18 MPG combined for R/Ts, with a Fuelly aggregated average near 15.4 MPG across many R/T entries.
Can the R/T hit 22+ MPG?
Yes - under steady highway conditions several owners and controlled tests recorded 22-23 MPG for the R/T V8.
Does cylinder deactivation help?
Yes - the HEMI's cylinder deactivation and fuel-saver systems can reduce fuel use in light-load cruising and contribute to higher highway MPG when the system is active.
Should I choose the R/T if fuel economy is primary?
If fuel economy is your top priority, the V6 Durango or other midsize crossovers typically offer better MPG than the R/T V8; choose the R/T only if you prioritize torque, towing, and V8 character.
