15 MPG combined. The 2024 Dodge Durango SRT AWD 6.4L isn’t winning any fuel efficiency awards, and frankly, it’s not trying to. This isn’t a vehicle purchased with economy in mind. It’s a three-row SUV that packs a ferocious naturally aspirated V8 engine capable of blistering acceleration and a matching soundtrack. Its buyers prioritize power, towing capacity, and a certain unapologetic swagger over saving a few dollars at the pump.

City and highway performance

The EPA estimates for the Durango SRT break down to 13 MPG in the city and 19 MPG on the highway. The city figure reflects the demands of stop-and-go traffic where the large-displacement engine spends more time idling and accelerating from a standstill. The highway figure, while still relatively low, demonstrates an improvement when the engine can settle into a more efficient cruising speed. The 8-speed automatic transmission helps here, keeping the engine in its sweet spot for power delivery while also allowing for relaxed cruising at higher speeds. The Durango SRT is not ideal for constant city driving. It excels on the open road.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Dodge Durango SRT AWD 6.4L at $3,850. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using the national average fuel price. It’s a significant sum and a stark reminder that owning a performance SUV comes with a considerable cost. However, for Durango SRT buyers, performance and practicality often outweigh concerns about fuel expenses.

Real-world expectations

While the EPA figures provide a standardized benchmark, real-world fuel economy for the Durango SRT can vary significantly based on driving habits and conditions. Expect significantly lower MPG if you frequently engage in aggressive acceleration or tow heavy loads. On the other hand, more conservative driving and prioritizing highway miles can yield slightly better results, perhaps even approaching the EPA’s 19 MPG highway estimate. Either way, be prepared for frequent trips to the gas station.

How it compares

Compared to other performance SUVs, the Durango SRT’s fuel economy is predictably low. The BMW X5 M, while equally powerful, achieves around 15 MPG combined, showing slightly better efficiency through technological advancements. Even the less powerful but similarly sized Ford Explorer ST manages around 20 MPG combined, largely due to its smaller, turbocharged V6 engine. Those seeking better fuel economy in a three-row SUV should consider options like the Toyota Highlander Hybrid, which boasts an impressive 36 MPG combined. However, that vehicle trades off performance for efficiency, a dealbreaker for the Durango SRT’s target audience. If you want to compare all Dodge fuel economy data, it is easy to do on our site.

Tips to maximize efficiency

While outright fuel efficiency isn’t the Durango SRT’s strong suit, you can take steps to reduce its thirst for fuel. Avoid aggressive acceleration and hard braking. The 6.4L Hemi responds predictably to throttle inputs, and easing into acceleration will help conserve fuel at the expense of outright acceleration.

Regularly check and maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces MPG, and impacts handling. Keeping your tires at the recommended pressure ensures optimal fuel efficiency and better tire life, both important for a vehicle of this size and performance.

Minimize idling. Modern engines don’t need extended warm-up periods, and idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute, turn off the engine. It can save fuel over time.

Consider using a fuel additive designed to clean fuel injectors. A clean fuel system operates more efficiently. Fuel additives can help remove deposits and ensure optimal fuel delivery, leading to slight improvements in MPG. Use a high-quality additive according to the manufacturer’s instructions.

Plan your trips efficiently, combining errands and minimizing unnecessary driving. Every cold start consumes extra fuel, so consolidating trips can reduce overall fuel consumption. Simple planning can also reduce your exposure to stop-and-go traffic, improving your overall fuel efficency.
