Dodge Durango RT Miles Per Gallon Feels Worse Than Expected
The Dodge Durango RT achieves EPA-rated fuel economy of 14 mpg city, 22 mpg highway, and 17 mpg combined for its standard 5.7-liter HEMI V8 engine in both rear-wheel-drive and all-wheel-drive configurations.
Official EPA Specifications
Every Durango RT model from 2018 through 2026 uses the potent 5.7L HEMI V8 paired with an 8-speed automatic transmission, delivering 360 horsepower and 390 lb-ft of torque. The EPA consistently rates this powertrain at 14 mpg in city driving, 22 mpg on highways, and 17 mpg combined, regardless of RWD or AWD setup. These figures stem from standardized tests conducted by the U.S. Environmental Protection Agency as of May 11, 2026, reflecting lab conditions with moderate acceleration and steady speeds.
| Model Year | Drivetrain | City MPG | Highway MPG | Combined MPG |
|---|---|---|---|---|
| 2019-2024 RT | RWD | 14 | 22 | 17 |
| 2019-2024 RT | AWD | 14 | 22 | 17 |
| 2025-2026 RT | RWD/AWD | 14 | 22 | 17 |
This table summarizes EPA ratings across recent years, showing no significant changes despite minor tuning updates in 2023 for smoother shifting. Real-world results often dip below these due to the SUV's 5,300-pound curb weight and performance-oriented tuning.
Real-World Fuel Economy Data
Owners report average MPG ranging from 15.5 to 18.9 mpg overall, based on crowdsourced data from over 485,000 tracked miles as of May 2026. Fuelly users log 15.8 mpg average for 2019 models across 1,632 fill-ups, while TrueDelta notes similar figures blending city and highway habits. Reddit threads from 2024-2026 highlight 16.1-16.5 mpg combined for daily drivers, dropping to 14 mpg with 70/30 city/highway splits.
- Highway-only: Up to 23 mpg in Car and Driver's 75-mph test loop, exceeding EPA by 1 mpg for V8 RT.
- City-heavy: 12-14 mpg common in stop-and-go traffic, per 88,000-mile 2018 owner logs.
- Mixed driving: 400-450 miles per 24.6-gallon tank, aligning with 16-18 mpg dashboard readings.
- Towing impact: Drops 20-30% to 10-12 mpg when hauling near 7,400-pound max capacity.
These stats reveal why many feel fuel economy underperforms expectations-performance SUVs prioritize power over efficiency, unlike lighter crossovers.
Historical Context and Evolution
The Durango RT lineage traces to 2011, but V8 efficiency stabilized post-2014 with HEMI MDS cylinder deactivation, boosting highway MPG from 20 to 22. In 2018 testing, Car and Driver clocked 23 mpg highway on a 200-mile I-94 loop at 75 mph GPS-verified speed, outpacing V6 rivals like the GMC Acadia. By 2023, EPA mandated updated testing (SAE J1634), yet RT ratings held firm at 17 combined.
- Pre-2014: 13 city/20 hwy on older 5-speed auto, thirstier without MDS.
- 2015-2017: 8-speed ZF transmission lifts hwy to 22 mpg; real-world hits 21.6 for some.
- 2018-2022: Peak efficiency claims, with 23 mpg tested; owners average 18.9 mpg over 88k miles.
- 2023-2026: No changes amid Stellantis shifts; SRT variants lag at 13/19 due to 6.4L.
"The V8 Durango outperformed its EPA rating by 1 mpg... besting the lighter Acadia V6." - Car and Driver, 2018 highway test.
This evolution underscores RT's balance of muscle and usability, though gas prices post-2025 volatility amplify owner gripes.
Factors Affecting MPG
Driving habits dominate variance: Aggressive acceleration from the 360-hp V8 slashes city MPG by 2-4 below EPA. AWD adds negligible penalty (under 1 mpg), but tires-standard 20-inch Pirellis-prioritize grip over rolling resistance. Premium fuel isn't required but yields 1-2 mpg gains per dyno tests dated March 15, 2024.
| Factor | MPG Impact | Example |
|---|---|---|
| Aggressive throttle | -3 to -5 mpg | 14 mpg vs. 19 mpg gentle. |
| Highway 75 mph | +1 to +3 mpg | 23 mpg tested. |
| Towing 5,000 lbs | -5 to -7 mpg | 10 mpg reported. |
| Winter tires | -1 to -2 mpg | AWD in snow. |
| MDS active | +2 mpg hwy | Cylinder deactivation on. |
Maintenance like fresh air filters (every 30,000 miles) and aligned wheels prevents 1-2 mpg losses, per NHTSA data from 2025.
Cost of Ownership Analysis
At $3.50/gallon (U.S. avg May 2026), 15,000 annual miles costs $4,118 yearly at 17 mpg-$294 more than V6 Durango's 21 mpg. Over 5 years/75,000 miles, that's $20,590 fuel vs. $16,786 for GT trim, per AAA computations updated April 2026. Resale holds strong at 55% after 5 years, offsetting via performance appeal.
- Annual fuel: 882 gallons at 17 mpg, $3,087 base.
- Vs. rivals: +15% costlier than Explorer, -5% vs. Tahoe.
- Tax credits: None for gas V8 post-2025 IRA tweaks.
Owner Experiences and Quotes
"My 2018 RT with 88k miles averages 18.9 mpg-55% highway, no towing," reports Reddit user u/DurangoDad42 on November 13, 2024. Another 2022 owner laments 320 miles/tank but praises 23 mpg bursts. Fuelly's 2023 cohort averaged 15.5 mpg over 4 vehicles.
"16.1 mpg dash average; 400-450 miles per tank without towing." - 2021-22 RT owner, r/DodgeDurango, 2024.
These anecdotes confirm real MPG beats EPA city but trails highway ideals, fueling the "worse than expected" sentiment amid $4/gallon spikes.
Tips for Maximizing Efficiency
Plan routes avoiding idling; use Valet Mode to limit revs. Post-2023 software update (build 29.1) optimizes MDS engagement, adding 0.5 mpg per forums dated February 2026. Track via app for personalized baselines-many hit 19 mpg tuned right.
- Monitor via Trip-o-meter reset post-fillup.
- Avoid short trips; preheat remotely to cut cold starts.
- Upgrade to 265/50R20 low-resist tires for 1 mpg gain.
- Service throttle body every 50k miles.
| Mod | Cost | MPG Gain |
|---|---|---|
| Cold air intake | $400 | +0.5-1 |
| Hypertech tuner | $500 | +1-2 |
| Lightweight wheels | $1,500 | +0.8 |
Mods yield modest returns without voiding warranty if CARB-approved.
Why It Feels Worse Than Expected
Benchmarks set high hopes: V6 GT's 19/26 skews perceptions, while RT's muscle (0-60 in 6.2 seconds) invites lead-footing. Post-2024 fuel hikes (up 22% YOY), 17 mpg stings vs. 25 mpg crossovers. Yet 570-mile highway range suits road trips, per 2018 tests.
Helpful tips and tricks for Dodge Durango Rt Miles Per Gallon Feels Worse Than Expected
How can I improve Durango RT MPG?
Activate eco mode via Uconnect to favor MDS, yielding 1-2 mpg gains; maintain 55-65 mph highway speeds for optimal 20+ mpg. Use 89-octane to engage timing advances, and keep tires at 35 psi cold-owners report 18 mpg sustained.
Is the Durango RT worse than competitors?
Yes, RT lags behind V6 rivals like Jeep Grand Cherokee (19/26 mpg) or Ford Explorer ST (18/25), but matches towing prowess at 7,400 lbs. Chevy Tahoe V8 hits similar 14/20, making RT competitive in muscle SUV class.
What's the range on a full tank?
The 24.6-gallon tank delivers 295-417 miles combined (17 mpg baseline), up to 540 highway miles at 22 mpg. Real-world caps at 400-450 miles per owner logs, low-fuel light at 3 gallons remaining.
Does AWD hurt MPG much?
No, AWD penalty is 0-1 mpg per EPA; both configs rate 14/22. Extra weight negligible vs. powertrain thirst.
Any 2026 updates for efficiency?
No hybrid or turbo for RT as of May 2026; V8 unchanged since 2015. SRT Hellcat variants confirmed discontinued post-2025.
Should I buy for MPG?
No-opt GT if efficiency trumps power; RT excels towing/hauling where V6 falters.
Electric Durango coming?
STLA Large platform teased for 2028, targeting 400-mile EV range; gas RT persists through 2027.
