13 MPG combined. That’s the number anyone considering a 2021 Dodge Durango SRT AWD with the 6.2L V8 should know. But to focus solely on that number is to fundamentally misunderstand this vehicle. This isn’t just basic transportation; it’s a three-row muscle car. Buyers aren’t cross-shopping Priuses; they’re comparing acceleration times and exhaust notes. Fuel economy is a secondary concern, outweighed by the noticeable thrill of 475 horsepower and the ability to tow over 7,000 pounds.

City and highway performance

The EPA estimates 12 MPG in the city and 17 MPG on the highway. The city figure reflects the Hemi’s thirst for fuel when constantly accelerating its considerable mass. The highway number, while not outstanding, is more acceptable, hinting at the potential for some efficiency during extended cruising. However, even on the open road, a heavy foot will quickly negate any attempt at maximizing economy, as the temptation to pass or simply enjoy the engine’s power is ever-present. More relevant than the specific numbers is the driving style they represent: aggressive acceleration and frequent high-speed runs will undoubtedly lower these numbers, while a more gentle approach can (slightly) improve them. But let’s be honest, no one buys a Durango SRT to drive gently.

Annual fuel cost

The EPA estimates an annual fuel cost of $4,450 for the 2021 Dodge Durango SRT AWD 6.2L. This calculation is based on driving 15,000 miles per year, using a national average fuel price. It’s a stark reminder of the financial commitment involved in owning this vehicle. This figure is significantly higher than most SUVs on the market, but potential buyers are likely aware of this and have factored it into their budget. Ultimately, the cost of fuel is the price of enjoying a high-performance SUV.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy will always vary. Factors like driving style, traffic conditions, and even tire pressure can influence the numbers you see on the Durango’s display. Owners who frequently drive enthusiastically can expect to see figures closer to 10 MPG in combined driving. Those who prioritize fuel conservation and spend more time on the highway might achieve slightly better results, perhaps approaching the EPA’s 17 MPG estimate. However, consistently exceeding the EPA estimates is unlikely, given the vehicle’s weight, power, and inherent thirst for premium gasoline. Comparing real-world owner experiences can offer valuable insights into what to realistically expect.

How it compares

The Durango SRT exists in a niche market, but it does have competitors. The BMW X5 M50i, with a twin-turbocharged V8, achieves a combined 18 MPG, significantly better than the Durango. However, it lacks a third row. The Mercedes-AMG GLE 63 S Coupe, another performance SUV, manages a similar 17 MPG combined, but commands a much higher price point. Even within the Dodge family, you can find similar size with different gas mileage using DURANGO MPG across all years. These comparisons highlight the trade-off between performance and fuel economy. The Durango SRT prioritizes raw power and towing capacity, accepting the fuel consumption penalty as a consequence. For buyers who need three rows and are willing to compromise on performance, alternatives like the Kia Telluride (23 MPG combined) or Honda Pilot (23 MPG combined) offer vastly superior fuel economy.

Tips to maximize efficiency

While the Durango SRT is not inherently fuel-efficient, there are steps you can take to minimize consumption. Avoid aggressive acceleration and hard braking. Smooth, gradual inputs will help keep the engine in its most efficient operating range. The eight-speed automatic transmission is programmed to shift early and often, so let it do its job.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and ensure it matches the recommended pressure listed on the door jamb. A simple, yet effective change for any vehicle.

Remove any unnecessary weight from the vehicle. Extra cargo adds load to the engine, forcing it to work harder and burn more fuel. Clear out any items you don’t need to haul around on a regular basis. While unlikely given the family focus, removing a roof rack or cargo carrier when not in use will also improve aerodynamics.

Use cruise control on the highway. Maintaining a consistent speed minimizes fluctuations in fuel consumption, and standard cruise control helps prevent unnecessary acceleration and deceleration instead of an advanced version. It’s all about consistency with the throttle.

Consider using a fuel additive specifically designed to improve combustion and fuel efficiency. Some additives can help clean fuel injectors and optimize the air-fuel mixture, potentially leading to a slight improvement in MPG. Of course, any gains will be marginal, but every little bit helps when faced with the realities of all Dodge fuel economy data.
