17 MPG combined isn’t going to win any awards, but for the 2015 Dodge Durango RWD with the 5.7L V8, it’s the price of admission. This isn’t a vehicle bought by those obsessed with fuel economy; it’s for families who need space, towing capacity, and the distinct rumble that only a Hemi can provide. The Durango buyer accepts this fuel consumption because their priorities lie elsewhere hauling kids, boats, and trailers take precedence over squeezing out every last mile per gallon.

City and highway performance

The 2015 Durango RWD 5.7L’s EPA estimates break down to 14 MPG in the city and 22 MPG on the highway. The city number reflects the engine’s thirst in stop-and-go traffic, where its ample power is largely unused. On the open road, the 8-speed automatic transmission helps to keep the engine in its sweet spot, contributing to the more palatable 22 MPG figure. However, passing maneuvers or maintaining speed up steep grades can quickly draw down the tank. Drivers should be mindful of their right foot to avoid plummeting below the EPA estimates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Dodge Durango RWD 5.7L at $3,100. This figure is calculated based on driving 15,000 miles per year, with an assumed fuel price reflecting national averages. It’s a useful benchmark for comparison, but fuel prices fluctuate regionally and can significantly impact your actual spending. Drivers who frequently tow or spend a lot of time in congested areas will likely exceed this estimate, while those with predominantly highway miles might come in slightly under.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy often varies. Owners report seeing figures close to the EPA estimates during mixed driving, but aggressive driving or frequent short trips can easily drop the average into the low teens. Towing, naturally, has a severe impact, potentially halving your MPG. It’s critical to consider your typical driving habits when evaluating the Durango’s fuel costs. This isn’t a vehicle for penny-pinchers; it’s for those who need its capabilities and are willing to pay the price at the pump.

How it compares

Compared to other large SUVs of its time, the 2015 Durango RWD 5.7L sits near the lower end of the fuel economy spectrum. A similarly equipped Chevy Tahoe RWD with the 5.3L V8 managed an EPA-estimated 16 MPG combined. A Ford Explorer with the 3.5L V6 (non-turbo) achieved a better 20 MPG combined, but lacked the Durango’s towing prowess. Even the V6-powered DURANGO MPG across all years is going to make a meaningful improvement. For Durango buyers, the comparison often boils down to capability versus fuel efficiency. Are they willing to sacrifice some MPG for the Hemi’s power and towing capacity, or would a more frugal option suffice? The decision often hinges on how frequently they use the vehicle’s full potential. Always compare all Dodge fuel economy data before making up your mind.

Tips to maximize efficiency

Gentle acceleration is key. The 5.7L Hemi has plenty of torque, so there’s no need to stomp on the gas pedal. Ease into acceleration smoothly and let the 8-speed transmission do its job. Aggressive acceleration will unnecessarily burn fuel without significantly improving your arrival time.

Maintain a steady speed on the highway. Cruise control is your friend. Varying your speed constantly requires more fuel to accelerate and decelerate. Setting cruise control on relatively flat stretches of highway will result in better MPG figures.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and maintain the recommended inflation level, which can be found on the sticker inside the driver’s side door jamb.

Reduce unnecessary weight. Carrying extra cargo in the Durango adds to the vehicle’s weight, decreasing fuel economy. Remove any items you don’t need for your trips. Every little bit helps, especially when combined with other fuel-saving techniques.
