15 MPG combined is not a number that excites hybrid owners. But for the buyer of the 2018 Dodge Durango SRT AWD, with its roaring 6.4L 8-cylinder engine, it’s a price they’re willing to pay. This isn’t about pinching pennies at the pump. It’s about ferocious acceleration, a menacing exhaust note, and the ability to tow a small house while transporting the family in relative comfort. The Durango SRT is a performance SUV first, a practical SUV second, and that priority dictates its thirst for fuel.

City and highway performance

The EPA estimates 13 MPG in the city and 19 MPG on the highway. The city figure will plummet with any enthusiastic application of the throttle, which is almost unavoidable given the engine’s addictive character. The highway figure is more achievable on long cruises, but even then, maintaining a consistent speed above 70 mph will see that number dip noticeably. This isn’t a vehicle designed for gentle, economical cruising. It’s designed to devour highway miles with authority and respond instantly to overtaking opportunities. The eight-speed automatic transmission does its best to optimize fuel economy, but ultimately, 475 horsepower demands its due.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2018 Dodge Durango SRT AWD is approximately $3,850. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel prices at the time of calculation. Given the Durango SRT’s preference for premium fuel, expect that number to fluctuate with market conditions. Those who frequently exploit the Durango SRT’s performance potential will undoubtedly exceed this amount. For details on all Dodge fuel economy data, reference the official EPA data.

Real-world expectations

Real-world MPG with the Durango SRT is a highly variable figure. Driven conservatively, with an emphasis on highway cruising, achieving the EPA’s 19 MPG is plausible. However, most owners don’t buy an SRT to drive it conservatively. Expect an average closer to 12-14 MPG with typical mixed driving and frequent bursts of acceleration. Towing will dramatically reduce fuel economy, potentially dropping into the single digits. The key takeaway is that the Durango SRT’s fuel consumption is directly proportional to the driver’s right foot. Owners should be fully aware of this reality. Those seeking maximum mileage from the DURANGO MPG across all years should consider one of the V6-powered models.

How it compares

Compared to other high-performance SUVs, the Durango SRT’s fuel economy is broadly similar. A BMW X5 M, with its twin-turbo V8, achieves a similar 16 MPG combined. The Mercedes-AMG GLE 63 S, another potent competitor, posts virtually identical figures. Even the less powerful Jeep Grand Cherokee SRT, sharing the same 6.4L engine, doesn’t offer a significant improvement. Stepping down to the Porsche Cayenne S with its twin-turbo V6 unlocks slightly better fuel economy, around 20 MPG combined, but at the expense of V8 rumble and a substantial reduction in towing capability. Buyers in this segment prioritize performance and capability over outright fuel efficiency; the Durango SRT holds its own against its direct rivals. The upcoming Cadillac Escalade-V should be monitored by Durango SRT prospects given its mission and immense horsepower.

Tips to maximize efficiency

Aggressive acceleration burns fuel faster. Be mindful of the Durango SRT’s power and try to moderate throttle inputs whenever possible. Gentle starts and gradual increases in speed will make a noticeable difference over time.

The eight-speed automatic transmission is programmed to shift quickly to higher gears, maximizing fuel economy. Avoid using the manual shift mode unless necessary, as it tends to hold gears longer and consume more fuel.

Regular maintenance is important. Ensure the engine is properly tuned, the tires are correctly inflated, and the air filter is clean. These seemingly minor factors can gradually contribute to reduced fuel efficiency if neglected.

Consider removing any unnecessary weight from the vehicle. Extra cargo adds load to the engine, requiring more power and burning more fuel. Leave the extra pair of golf clubs at home if you’re not heading to the course.

Plan journeys in advance, optimizing routes to avoid stop-and-go traffic. Constant braking and acceleration dramatically impact fuel consumption. Smooth, flowing traffic is the ideal scenario for maximizing MPG, even if it might be unlikely in a Durango SRT.
