A rear-wheel-drive 2017 Dodge Durango with the 3.6L V6 gets 21 MPG combined. Nobody is buying this Durango for its fuel sipping capabilities. They’re buying it because they need to haul the family, the gear, maybe even the occasional trailer, without sacrificing the butch styling and surprisingly engaging driving dynamics that Dodge manages to inject into even its larger vehicles. They accept the fuel economy because it’s the price you pay for genuine capability and a healthy dose of attitude.

City and highway performance

The EPA estimates for the 2017 Dodge Durango RWD with the 3.6L V6 are 19 MPG in the city and 26 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the Durango’s weight and naturally aspirated engine work against it. The 26 MPG highway rating is more palatable, and achievable when cruising at consistent speeds. The eight-speed automatic transmission helps in both scenarios, keeping the engine in its optimal power band and contributing to respectable fuel economy considering the Durango’s size.

Annual fuel cost

The EPA estimates the annual fuel cost for this Durango configuration at $2,100. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on driving habits, local fuel prices, and the type of fuel used. Higher octane fuel won’t improve fuel economy in this engine. It’s a calculation that provides a useful benchmark for comparing the Durango to other vehicles.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary. Aggressive driving, frequent short trips, carrying heavy loads, and towing will all reduce MPG. Careful driving, proper tire inflation, and regular maintenance can help you get closer to the EPA estimates. Owners who prioritize fuel economy can expect to see figures in the low 20s during mixed driving. Drivers with a heavy foot or frequent towing needs should prepare for numbers closer to the high teens. Checking the validity of your real-world estimates against the EPA figure is a good idea since the EPA estimate is based on a wide range of simulated driving conditions.

How it compares

The Durango’s fuel economy lands roughly in the middle of its competitive set. A 2017 Toyota Highlander with its 3.5L V6 and front-wheel drive achieves a slightly better 22 MPG combined, an important consideration for buyers who might prioritize fuel economy and expect more efficiency from the Toyota. The Ford Explorer with its 2.3L EcoBoost turbo four-cylinder, while offering similar power, also manages around 22 MPG combined, suggesting that downsizing may not always deliver significant fuel savings in a vehicle of this size. The Jeep Grand Cherokee, a close relative to the Durango which also provides all Dodge fuel economy data for other models, with its 3.6L V6 and rear drive offers similar figures to the Durango at 19 MPG city and 26 MPG highway, highlighting the direct correlation between vehicle architecture, weight and fuel economy in the three-row SUV segment. Buyers often cross-shop these models, and the fuel economy differences are often secondary to factors like styling, features, and brand preference.

Tips to maximize efficiency

The Durango’s 3.6L V6 is a proven engine, but it’s not a fuel-sipping hybrid powerplant. Smooth acceleration and avoiding unnecessary hard stops can make a noticeable difference in fuel consumption. Resist the urge to bury the accelerator pedal, the engine responds best to gradual throttle inputs. Anticipating traffic flow and maintaining a steady speed will contribute to better mileage, especially on the highway.

Tire pressure is often overlooked, but properly inflated tires reduce rolling resistance and improve fuel economy, consult the sticker on the driver’s side doorjamb for the correct pressure. Also, keeping up with scheduled maintenance, particularly oil changes and air filter replacements, ensures the engine runs efficiently. A clean air filter allows for optimal airflow, while fresh oil reduces friction within the engine.

Minimize idling whenever possible. Today’s engines are designed to warm up quickly while driving, and prolonged idling wastes fuel. If you’re waiting for someone or stopped for an extended period, turn off the engine. The Durango’s air conditioning system can also impact fuel economy. Use it sparingly, especially at lower speeds when opening the windows can be a more fuel-efficient option.

Consider driving in “Eco” mode if your Durango is equipped with that feature. While it may slightly reduce throttle response and shift points, it can help optimize fuel economy in certain driving situations. The trade-off in performance is often minimal, and the potential fuel savings can be worthwhile. The key to maximizing efficiency in the 2017 Dodge Durango RWD 3.6L lies not in drastic changes, but in subtle adjustments to driving habits and consistent maintenance.
