15 MPG combined is not a selling point for the 2021 Dodge Durango SRT AWD, nor should it be. This is a three-row muscle SUV, a family hauler that packs a naturally aspirated 6.4L Hemi V8 producing 475 horsepower. This Durango exists to deliver blistering acceleration and a menacing exhaust note while occasionally shuttling kids to soccer practice. Its target demographic prioritizes power and presence over lower fuel costs, understanding that such performance demands premium gasoline.

City and highway performance

The EPA estimates the 2021 Dodge Durango SRT achieves 13 MPG in the city and 19 MPG on the highway. These figures are highly dependent on driving style. Heavy throttle use will rapidly deplete the fuel tank and worsen real-world mileage, especially in the city where stop-and-go traffic provides the opportunity to use the Hemi’s torque. On the highway, a more disciplined approach can approach or even slightly exceed the EPA’s estimate, but sustained high-speed cruising will still consume a lot of fuel.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Dodge Durango SRT AWD at $3,850. This figure is based on driving 15,000 miles per year, split roughly 55% city and 45% highway, and using the national average fuel price. The SRT requires premium fuel, and fuel prices fluctuate, so owners should anticipate that their actual annual fuel expenditure could vary substantially from this baseline. This is simply a benchmark number that allows you to see how this vehicle compares to others. You can view all Dodge fuel economy data to get a sense of the broader brand performance.

Real-world expectations

While the EPA estimates provide a useful comparison tool, prospective Durango SRT owners should adjust their expectations. Achieving the sticker MPG requires attention to driving habits and adherence to posted speed limits. The temptation to unleash the Hemi’s power is ever-present, and fuel consumption will reflect that. Most owners report combined fuel economy figures closer to 12-14 MPG in mixed driving, and some see even lower numbers with frequent spirited acceleration.

How it compares

The Durango SRT’s fuel economy is predictably poor compared to others in its niche. The Mercedes-AMG GLS 63, another high-performance three-row SUV, achieves a combined 16 MPG, slightly better, but still hardly economical. The BMW X5 M50i, while not a direct three-row competitor, offers comparable performance with a combined 18 MPG rating. Even the V6-powered Durango models offer significant MPG gains. The Durango R/T with the 5.7L Hemi manages a combined 17 MPG, a tangible improvement for those willing to sacrifice some horsepower. Buyers drawn to the SRT are generally not cross-shopping for maximum efficiency, but understanding the competitive landscape provides context.

Tips to maximize efficiency

Outright fuel efficiency might not be the primary concern of Durango SRT owners, but there are actions you can take to minimize fuel consumption. Avoid aggressive acceleration and hard braking. The Hemi V8 responds immediately to throttle inputs, but gentle acceleration minimizes the amount of fuel injected into the cylinders.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and maintain them at the recommended levels listed on the driver’s side doorjamb.

Plan your trips strategically to avoid stop-and-go traffic. Idling consumes fuel without covering any distance, so routing your journey to minimize congestion can make a difference, particularly in urban environments.

Remove unnecessary weight from the vehicle. Excess cargo adds to the overall vehicle weight, increasing the engine’s workload. Clearing out items you don’t need can improve your fuel economy.

Consider using the Eco mode, if equipped. This mode re-maps the throttle response and shift patterns to prioritize fuel efficiency. While it impacts performance, it can be effective for daily commuting and less demanding driving situations.
