Model-year fuel efficiency overview
Each refresh of the Dodge Durango platform has shifted its fuel-efficiency curve, especially after the 2014 switch to an 8-speed automatic transmission that tightened gear spacing and reduced highway RPM. From 2011 through 2017, the 3.6L Pentastar V6 typically delivered about 17-19 MPG city and 24-26 MPG highway, for a 21-22 MPG combined window, while the 5.7L HEMI V8 stayed in a 14 city / 22 highway slot, or roughly 17 combined across those years. By 2020-2021, EPA estimates had stabilized around 21 combined MPG for the 3.6L V6 (19 city/26 highway) and 17 combined for the 5.7L V8 (14 city/22 highway), with AWD sapping roughly one MPG in both city and highway numbers. The 2023-2025 model years extend this band slightly, with GT-series trims and 3.6L V6-based configurations still hovering near 19-20 combined, while SRT and Hellcat variants fall into the 12-15 combined range despite minor efficiency tweaks.Engine-driven efficiency splits
Fuel economy on the Dodge Durango is overwhelmingly driven by engine choice, not just model year. The base 3.6L Pentastar V6, available on most SXT, GT, and Citadel trims since 2011, consistently delivers 18-19 MPG city and 25-26 MPG highway, for a combined 21-22 MPG window that makes it competitive with many mid-size crossovers. Because this engine runs on regular unleaded and rarely exceeds 300 horsepower, it underpins the "efficient" side of the Durango lineup. The 5.7L HEMI V8, tuned for towing and all-around muscle, usually posts 14 MPG city and 22 MPG highway, good for about 17 combined, regardless of whether the 2018 or 2024 model year is on the plate. High-performance SRT 392 and Supercharged Hellcat engines pull the scale down hard: the 6.4L SRT 392 averages 13 city / 19 highway (~15 combined), while the supercharged 6.2L Hellcat can dip to 12 city / 17 highway (~13 combined) in the 2024-2025 years.Quick-reference data table by engine type
The following table summarizes typical EPA-estimated fuel efficiency for common Durango powertrains across recent model years; numbers are approximate but reflect published 2020-2025 figures.| Engine | Fuel Type | City MPG (typical) | Highway MPG (typical) | Combined MPG (typical) |

| 3.6L Pentastar V6 (RWD) | Regular | 19 | 26 | 21-22 |
| 3.6L Pentastar V6 (AWD) | Regular | 18 | 25 | 20-21 |
| 5.7L HEMI V8 (RWD/AWD) | Regular | 14 | 22 | 17 |
| SRT 6.4L HEMI (AWD) | Premium | 13 | 19 | 15 |
| SRT Hellcat 6.2L supercharged (AWD) | Premium | 12 | 17 | 13 |
Model-year highlights and surprises
One of the biggest surprises for shoppers is how little overall fuel economy has moved for the 5.7L-equipped Dodge Durango since 2014, despite turbo-charged rivals shedding 2-3 MPG in the same window. The 2014 update brought an 8-speed automatic and slightly better aerodynamics, but most 5.7L trims still sit at 14/22 rather than moving into the 16/25 range that theory would suggest. Conversely, the 3.6L V6 has held its ground remarkably well, with 2024-2025 GT and Citadel trims still posting 19/26 combinations that are functionally identical to the 2018 spec. That stability means buyers who prioritize efficiency over power can effectively "skip" model-year bells and whistles and focus on trim and drivetrain, since the underlying fuel economy numbers are largely unchanged.Tanking and real-world context
All recent Dodge Durango variants share a 24.6-gallon fuel tank, which greatly softens the sting of low MPG figures on road trips. With a 3.6L V6 and 26 MPG highway, that tank can yield roughly 630 miles between refills, while the 5.7L V8 drops that to about 540 miles, and the Hellcat can fall as low as 420 miles in mixed driving. Owner-tracked data from repositories like Fuelly show that real-world averages often sit 1-2 MPG below EPA labels, with 2021-2023 V6 Durangos averaging about 17-18 MPG overall and 2022-2024 V8 models closer to 15-16 MPG, depending on driving style and terrain. That gap underscores that the Dodge Durango behaves like most full-size SUVs: its published numbers are optimistic but not wildly off base.How drivetrain and trim affect fuel economy
Two key hardware choices-drivetrain and trim package-can nudge Dodge Durango fuel economy by 1-2 MPG in a single year. The 3.6L V6 with rear-wheel drive typically posts 19 city / 26 highway, while the same engine in AWD trims loses about 1 MPG in both environments, landing at 18 city / 25 highway. The 5.7L V8 behaves similarly, with RWD and AWD versions both quoted at 14 city / 22 highway, but real-world logs hint that AWD adds a small parasitic drag in stop-and-go traffic. Trim-level differences are mostly cosmetic or comfort-oriented, but heavier SRT and R/T packages increase curb weight and aerodynamic drag, which helps explain why SRT 392 and Hellcat variants cannot match the 17 MPG combined figure of the 5.7L despite similar displacement. A 2025 field-test summary of 120 Durango SRTs found their average real-world fuel economy was 14.2 MPG, within 0.8 MPG of the EPA-rated 15 combined, which is unusually tight for a high-performance SUV.Guidance for buyers by need
For buyers whose primary concern is fuel economy, the 3.6L V6 in a GT or Citadel trim with RWD delivers the best balance of utility and efficiency, with 19/26 numbers and 21-22 combined without sacrificing three-row seating or towing capacity. Those who frequently tow or tow in mountainous terrain may still opt for the 5.7L V8, understanding that they will consistently pay for that extra 70-100 horsepower with roughly 4-5 MPG less than the V6. Enthusiasts who are drawn to the SRT or Hellcat badges should treat the Dodge Durango as a performance SUV first and an efficiency vehicle second; the 12-13 MPG combined of the Hellcat is closer to a full-size muscle truck than a family hauler. However, even those trims still outpace many older V8s from the early-2000s, which commonly sipped under 12 combined MPG, so the efficiency curve has improved modestly over two decades.Efficiency-improving behaviors and tech
Several built-in technologies nudge the Dodge Durango toward better fuel economy, especially in the 2020-2025 years. The 8-speed automatic transmission spends more time in overdrive and uses lock-up clutches at lower speeds, which can reduce highway consumption by roughly 0.5-1 MPG compared with a 5-speed from the early 2010s. Cylinder deactivation on the 5.7L HEMI V8 and variable valve timing on the 3.6L V6 also cut fuel use under light load, although enthusiast-driven SRTs often deactivate these systems in aggressive drive modes. On the behavioral side, real-world logging shows that 2021-2025 durango owners who keep highway speeds under 70 mph and avoid aggressive launches can gain 1.5-2 MPG over the EPA highway rating, while those who routinely exceed 80 mph and use "Sport" mode often fall 2-3 MPG below label. That spread means that the fuel economy experience of a single model year can vary widely depending on how the vehicle is driven.Price-of-fuel and ownership-cost perspective
Putting these numbers into monetary terms, a 2024-2025 Dodge Durango with the 3.6L V6 and 21 MPG combined will cost roughly 15-18 cents per mile at $3.20/gallon, while a 5.7L V8 at 17 MPG combined runs closer to 19-22 cents per mile under the same fuel price. The Hellcat, at 13 MPG combined, can push that figure toward 25-28 cents per mile, which is comparable to many full-size pickup trucks rather than family SUVs. Over a 100,000-mile ownership period at 15,000 miles per year, the V6-based Durango can save roughly $1,500-$2,000 in fuel versus the 5.7L V8, assuming stable fuel prices around $3.20/gallon, and the gap widens to $3,000-$4,000 versus the Hellcat. That differential may justify the performance trade-off for some buyers, but for others the Dodge Durango simply becomes a premium performance SUV with a premium fuel bill.Are newer Durango model years more efficient than early-2010s ones?
Newer Durango model years are modestly more efficient than early-2010s ones, mainly due to the 8-speed automatic and refined engine calibrations, but the gains are measured in tenths and not whole miles per gallon. The 3.6L V6 has held a roughly 21-22 combined MPG band since 2014, while the 5.7L V8 has stayed near 17 combined, so the headline fuel economy story across model years is stability rather than breakthrough improvement.

Helpful tips and tricks for Dodge Durango Fuel Efficiency By Model Year Big Surprises
What is the most fuel-efficient Dodge Durango model year?
The most fuel-efficient mainstream Dodge Durango model years are 2020 through 2025 equipped with the 3.6L Pentastar V6 and rear-wheel drive, which consistently post 19 city / 26 highway and 21-22 combined MPG across EPA labels. AWD versions of those same years are slightly less efficient at 18 city / 25 highway but still sit at the top of the Durango efficiency stack compared with V8-powered trims.
How much fuel does a Dodge Durango use in real-world driving?
Owner-tracked data from 2020-2024 shows that 3.6L V6 Durangos average about 17-18 MPG in mixed driving, while 5.7L V8 models average 15-16 MPG, about 1-2 MPG below their EPA labels. High-performance SRT and Hellcat trims fall closer to 13-14 MPG in real-world logs, reflecting aggressive driving patterns plus the inherent thirst of supercharged hardware.
Why are SRT and Hellcat Durangos so inefficient?
The SRT 392 and Hellcat engines on the Dodge Durango trade efficiency for massive torque and acceleration, running high-boost supercharging and wide-open throttle much of the time, which pushes fuel flow far beyond the 5.7L V8's 17 MPG envelope. The Hellcat's 6.2L supercharged V8 is tuned for performance rather than economy, so its 12-13 MPG combined is acceptable for its niche but not competitive with mainstream SUVs.
Does AWD significantly hurt Dodge Durango fuel economy?
AWD does mildly hurt Dodge Durango fuel economy, typically reducing the 3.6L V6 from 19 city / 26 highway to 18 city / 25 highway, or about a 1 MPG drop in each environment. The 5.7L V8 shows less of a gap in EPA ratings, but real-world data suggests that AWD adds a small parasitic loss in stop-and-go traffic, which can widen the spread under mixed driving.
Can driving habits change Durango fuel economy by more than 2 MPG?
Yes, driving habits can change real-world Dodge Durango fuel economy by 2-3 MPG or more compared with EPA labels, especially on highway runs. Keeping speeds under 70 mph, using gentle acceleration, and avoiding constant "Sport" mode on the 8-speed can push owners above label, while heavy traffic, towing, and aggressive launches can push them well below.
