Dodge Durango GT Miles Per Gallon: Real-World Efficiency Explained

The 2020-2026 Dodge Durango GT models equipped with the 3.6-liter V6 engine return an EPA-estimated 18 miles per gallon (mpg) in the city, 25 mpg on the highway, and 21 mpg combined when fitted with all-wheel drive (AWD). That combined figure means a full 24.6-gallon fuel tank can push the Durango GT range to roughly 515-615 miles in mixed driving, depending on load and terrain. While that V6 setup is far from hybrid-car efficient, it positions the Durango GT as one of the more fuel-conscious choices in the three-row SUV segment.

Official EPA Ratings for the Durango GT

For the 2024-2026 model years, Dodge standardizes the 3.6-liter Pentastar V6 across the SXT and GT trims, yielding very similar EPA numbers. Front-wheel-drive (4x2) Durango GTs are rated at about 19 city / 26 highway mpg, while the more common AWD GT trim trades a single mpg in each metric for added traction, landing at 18 city / 25 highway / 21 combined mpg. Those figures are derived from the EPA's standardized 11-mile city and 10-mile highway test cycles, which simulate real-world stop-and-go and highway-speed driving.

By comparison, the 5.7-liter HEMI V8 in the Durango R/T drops to approximately 14 city / 22 highway mpg, and the 6.4-liter SRT 392 and 6.2-liter Hellcat variants fall further into the teens, making the Durango GT fuel economy look relatively economical for the platform. Independent testers at Car and Driver have recorded real-world highway figures around 23 mpg for V8-powered Durangos, which underscores how the V6-based GT can often beat its EPA "combined" rating during steady-speed runs.

Real-World MPG vs. EPA Estimates

Community-logged data from sites like Fuelly and TrueDelta confirm that the Durango GT real-world mileage typically clusters just below or reasonably close to the EPA combined 21 mpg figure. For example, Fuelly's 2020 Durango GT entries average around 17-18.8 mpg, reflecting frequent stop-and-go traffic and occasional towing duty. TrueDelta's broader V6 Durango dataset shows an average of about 21.6 mpg, suggesting that disciplined highway-leaning drivers can essentially match the official "combined" rating.

Aggressive driving, cold weather, and roof-mounted cargo can depress Durango GT returns by 10-25 percent, especially in city traffic. In contrast, highway-only trips at 65-70 mph with light loads often push observed economy into the upper 20s, aligning with the 25 mpg highway rating. That spread-from low-teens in heavy city use to high-20s on long highway legs-illustrates why many owners treat the official mpg as a "best-case mixed" benchmark rather than a hard floor.

How the Durango GT's Engine and Transmissions Affect MPG

The 3.6-liter Pentastar V6 in the Durango GT produces about 293 horsepower and 260 lb-ft of torque, paired with an 8-speed automatic transmission that includes manual shift modes. All-wheel drive, while adding roughly 100-150 pounds of unsprung weight, still keeps the GT's fuel-flow patterns closer to front-wheel-drive -trim figures than to the V8-based R/T and SRT variants. The 8-speed box's wide gear spread and quick upshifts allow the engine to run at lower RPMs on the highway, which directly supports the 25 mpg highway rating.

Engine-management features such as variable valve timing and modest cylinder-deactivation hardware on the V6 help maintain consistent Durango GT fuel efficiency under part-throttle conditions. However, the Durango's 4,500-5,000-pound curb weight and 20-cubic-foot cargo space mean aerodynamic drag and rolling resistance remain significant; even at light loads, the GT can't match compact-crossover efficiency. For buyers prioritizing mpg over outright power, the V6 Durango GT remains the logical sweet spot inside the Durango lineup.

Fuel Costs and Ownership Impact

With a 24.6-gallon fuel tank and an average cost-to-operate figure in the mid-$170-per-month range (based on 15,000 miles annually and current national fuel prices), the Durango GT running costs sit comfortably below the V8-powered trims. Assuming 21 mpg combined and $3.50-per-gallon regular unleaded, owners can expect to spend roughly $1,200-$1,400 per year in fuel if driving 12,000-15,000 miles. In contrast, the 5.7-liter HEMI R/T can push annual fuel outlays 30-40 percent higher due to its 14 mpg city rating and heavier thirst under acceleration.

Over a five-year ownership horizon, that gap can translate into roughly $3,000-$4,000 more at the pump for the V8 models compared to the V6-based Durango GT. While CO₂ emissions for the GT still hover around 6.9 tons per year-well above the sub-6-ton threshold of many compact SUVs-the V6 Durango's balance of three-row utility and moderate fuel consumption makes it a pragmatic choice for families. For those weighing new versus used, 2018-2020 Durango GTs with similar 3.6-liter engines and 8-speed transmissions can often be had for under $25,000 and still deliver roughly 18-22 mpg in real-world use.

Key MPG Comparison Table by Trim

This Durango trim-by-trim MPG table highlights how choosing the GT (or SXT) over the R/T or SRT models can save roughly 4-7 mpg in combined driving, which compounds into thousands of dollars in fuel savings over time. For buyers who occasionally tow, the GT's 6,200-pound maximum towing capacity with the proper tow package still supports family-scale hauling without the full-time penalty of a V8 engine.

Practical Tips to Maximize Durango GT MPG

To help owners squeeze closer to the Durango GT highway rating of 25 mpg, several evidence-backed driving habits make a measurable difference:

• Use cruise control on level highways at 65-70 mph to keep engine RPMs low and eliminate throttle surges.
• Avoid aggressive acceleration; studies show that "lead-foot" starts can reduce observed mpg by 10-20 percent in large SUVs.
• Keep tires at or slightly above the recommended PSI; underinflated tires can cut efficiency by 2-5 percent due to higher rolling resistance.
• Minimize roof racks and cargo boxes when not in use, as aerodynamic drag can drop highway mileage by 5-10 mpg at speed.
• Use the available "Eco" or "Auto" drive mode, if equipped, to prioritize longer gear holds and smoother throttle response.

By combining these habits, many Durango GT owners report seeing 23-26 mpg on long highway runs, approaching the 25 mpg EPA highway target. In dense urban environments, however, factors such as elevation changes, frequent idling, and heavy loads will keep the Durango GT city mileage closer to 16-18 mpg, even with careful driving.

How the Durango GT Compares to Rivals

When stacked against competitors such as the Ford Explorer, Chevrolet Traverse, and Honda Pilot, the Durango GT fuel economy is roughly par with V6-based rivals but trails turbo-four entries by about 3-5 mpg in combined driving. For example, the 2024 Ford Explorer with a 2.3-liter EcoBoost engine can achieve around 22-23 city / 29-30 highway mpg, while the 3.6-liter-equipped models sit closer to the Durango GT's 18 city / 25 highway envelope. The Chevrolet Traverse's 3.6-liter V6 also returns about 18/26 mpg, giving the Durango GT nothing to apologize for in the segment.

What the Durango GT gains over many rivals is a more muscular design language and a reputation for towing, while holding fuel-consumption numbers in the mid-20s on the highway. For buyers who want a muscular three-row SUV without plunging into Hellcat-level fuel bills, the GT's balance of 18 city / 25 highway mpg and 6,200-pound towing capacity makes it a compelling middle-ground machine.
