18 MPG combined is the price of admission to the 2017 Dodge Challenger SRT 6.4L club, a club whose members prioritize raw power, retro styling, and thunderous V8 soundtracks above all else. It’s a figure that would be appalling in a compact sedan, but for a near-4,300-pound muscle car packing 485 horsepower, it’s almost expected.

City and highway performance

The EPA estimates suggest 15 MPG in the city and 25 MPG on the highway. That 10 MPG gap between the two figures clues you in to the Challenger SRT 6.4L’s personality. It’s happiest cruising on the open road, where its effortless torque and smooth-shifting eight-speed automatic can stretch a gallon further. Urban environments, with their stop-and-go traffic, become a constant reminder of the big engine lurking under the hood, eagerly consuming fuel with every acceleration.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2017 Dodge Challenger SRT 6.4L is $3,200. This figure is based on driving 15,000 miles per year and assumes current national average fuel prices. Keep in mind that this is only an estimate. Your personal fuel costs will vary depending on your driving habits, the type of driving you do (city versus highway), and the price of gasoline in your area. Aggressive driving, a heavy foot, and a penchant for hearing that exhaust note will quickly inflate that number.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the Challenger SRT 6.4L can vary significantly. Drivers who frequently indulge in the car’s performance potential will likely see figures closer to the city estimate, or even lower. Conversely, those who prioritize highway cruising and restraint might be able to match or slightly exceed the 25 MPG highway estimate. The key takeaway is to manage expectations. This is not a fuel-sipping commuter car; it’s a performance machine that demands respect at the pump.

How it compares

Compared to other performance coupes of the era, the Challenger SRT 6.4L sits in a predictable position. The Ford Mustang GT with the Coyote 5.0L V8 and automatic transmission achieves around 19 MPG combined, edging out the Challenger slightly. The Chevrolet Camaro SS, however, offers similar performance and usually posts similar fuel economy to the Mustang. These differences are marginal and usually not the primary deciding factor for buyers in this segment. Someone cross-shopping these three vehicles is making choices based on styling, brand loyalty, and overall driving experience, not squeezing out an extra mile per gallon.

If you open up the market to other large coupes, like a BMW 440i, you could see combined mpg numbers of 25 mpg. But someone seeking that class of vehicle isn’t likely looking at a Challenger. It is possible to review all all Dodge fuel economy data and find more efficient choices, but you won’t find anything offering this kind of American muscle. Consider looking through CHALLENGER MPG across all years before making a purchase.

Tips to maximize efficiency

The easiest way to improve fuel economy in the 2017 Challenger SRT 6.4L is to adopt a smooth and consistent driving style. Avoid sudden acceleration and hard braking, as these actions consume significantly more fuel. The Challenger SRT can achieve respectable highway mileage if driven reasonably, so anticipate traffic flow and maintain a steady speed.

Take advantage of the Challenger’s cruise control, especially on long highway drives. Cruise control helps maintain a consistent speed, minimizing unnecessary throttle adjustments and optimizing fuel consumption. This is especially effective in relatively flat areas with minimal changes in elevation.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended pressure listed on the door jamb or in the owner’s manual.

Regular maintenance is critical for optimal fuel economy. A well-maintained engine runs more efficiently, so follow the recommended service schedule for oil changes, air filter replacements, and spark plug replacements. A clean air filter, in particular, helps the engine breathe easier, improving fuel efficiency.
