19 MPG combined is the established reality for the 2017 Dodge Challenger equipped with the 5.7L Hemi V8. Let’s be blunt: it’s not a fuel sipper. Judging this car solely on its economy misses the point entirely. This Challenger exists to deliver a visceral, old-school muscle car experience, and that comes at a price. Buyers aren’t cross-shopping this against Priuses. They want the rumble, the power, and the presence that only a V8 Challenger can provide, and they accept the fuel consumption as the cost of admission.

City and highway performance

The official EPA estimates break down to 16 MPG in the city and 25 MPG on the highway. The city figure reflects what happens when you’re constantly dealing with stop-and-go traffic and short bursts of acceleration. The Challenger’s weight and V8’s inherent thirst become readily apparent.

The highway number is more palatable. On long stretches of open road, the 8-speed automatic transmission helps keep the engine in a more fuel-efficient range, and the Challenger becomes a surprisingly comfortable long-distance cruiser. Just don’t expect those highway MPG numbers if you’re constantly overtaking or engaging in spirited driving.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2017 Dodge Challenger 5.7L V8 is $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will depend on your driving habits, the type of driving you do (city versus highway), and the prevailing fuel prices in your area. If you drive mostly in the city and have a heavy foot, expect to spend significantly more than $2,750 per year.

Before committing to the Challenger’s demands, consider all Dodge fuel economy data to see if other models might better suit your budget.

Real-world expectations

Forget the EPA sticker once you get behind the wheel. Achieving even those modest numbers requires conscious effort. The temptation to dip into the Hemi’s considerable power is ever-present, and resistance often proves futile. Expect to see numbers closer to the low teens in mixed driving if you enjoy the car’s performance capabilities.

Some careful owners on forums dedicated to the Challenger and CHALLENGER MPG across all years may report higher numbers, but they’re likely employing hypermiling techniques that most drivers won’t want to adopt in a car like this. This car is about the experience, not squeezing every last mile from a gallon.

How it compares

Compared to other performance cars, the Challenger’s fuel economy is predictably lower than that of its V6-powered rivals. A 2017 Ford Mustang EcoBoost, for example, gets a combined MPG of around 25, while the V6 Camaro gets a combined MPG of around 22. The V8-powered Mustang GT, a more direct competitor, posts similar MPG figures to the Challenger, around 19-20 combined.

The difference, while not massive, can still add up over time. The Challenger’s unique blend of retro styling, spacious interior, and available all-wheel drive (on V6 models, obviously) gives it appeal that differentiates it from the Mustang and Camaro. If fuel economy is a primary concern, these other options, especially with their smaller engines and lighter footprints could be better. The Challenger V8 is bought for its specific persona, and that overrides the need for ultimate fuel efficiency.

Tips to maximize efficiency

Smooth acceleration is key. Avoid sudden bursts of speed, especially from a standstill. The 5.7L Hemi responds well to a gentle throttle, and you’ll find that you can maintain decent speed without constantly burying your foot in the accelerator. Using a light foot will drastically improve your daily MPGs.

Take advantage of the Challenger’s cruise control on the highway. Setting a constant speed can help maintain a consistent level of fuel consumption. Avoid excessive speeding, as fuel economy drops off dramatically at higher speeds. Driving at a steady pace helps keep the engine in a more optimal efficiency range.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels. You can find the recommended pressure on a sticker inside the driver’s side door.

Consider using the Challenger’s Eco mode, if equipped, during less-spirited driving conditions. This mode adjusts the engine and transmission mapping to prioritize fuel economy. While it might dampen the car’s performance, it can make a noticeable difference in your MPG, especially during city driving.
