18 MPG combined is the fuel economy for the 2018 Dodge Charger SRT 6.4L, a full-size sedan that prioritizes strong power and aggressive styling over saving gas. This isn’t a car for those looking for a fuel-sipping ride. This is a muscle car with four doors, designed for drivers who appreciate the rumble of a naturally aspirated V8 and the feeling of serious acceleration. Saving gas is a secondary consideration, a trade-off for the Charger SRT’s unique combination of practicality and performance.

City and highway performance

The EPA estimates the 2018 Dodge Charger SRT 6.4L gets 15 MPG in the city and 25 MPG on the highway. The city number shows the engine’s need for fuel during stop-and-go driving, where the heavy car and responsive throttle encourage less-than-economical driving. The highway number, while better, still lags behind smaller sedans that use less gas. The 8-speed automatic transmission tries to manage the engine’s power and get better fuel consumption at cruising speeds, but it can’t overcome the demands of a large V8 pushing a hefty vehicle.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2018 Dodge Charger SRT 6.4L is about $3,200. This is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel is recommended for the 6.4L engine to keep its performance at its best, and changes in fuel prices can change your real expenses. This $3,200 is an estimate, but your driving habits and local fuel costs will determine what you actually spend.

Real-world expectations

While the EPA estimates provide a starting point, expect your real-world MPG to change depending on how and where you drive. The Charger SRT’s power is easily accessible, and drivers who often tap into the engine’s potential will likely see fuel economy numbers lower than the official estimates. However, those who drive more gently and spend a lot of time on the highway might get numbers closer to, or even a little above, the EPA ratings. But realistically, if you buy this car, fuel costs are probably not your first concern.

How it compares

The 2018 Dodge Charger SRT 6.4L’s fuel economy, compared to other performance sedans, creates a clear picture. A vehicle like the Cadillac CT5-V with its 3.0L Twin Turbo engine achieves around 21 MPG combined, even though its power is similar with more current technology. The BMW M550i xDrive, with its own strong V8 and all-wheel-drive, manages about 20 MPG combined. A good comparison may be vehicles like the Ford Mustang GT, which gets around 19 MPG combined, but has less passenger space. The Charger SRT’s fuel consumption shows it’s a classic muscle car in a segment that has more technologically advanced options that save gas.

Tips to maximize efficiency

Resist the Urge: It’s easier said than done, but avoid quick acceleration and hard braking. The Charger SRT’s V8 is tempting, but a lighter touch on the gas pedal will improve fuel consumption. Try to see traffic and keep a consistent speed whenever you can.

Use the Drive Modes: Try the different drive modes in the Charger SRT. The “Eco” mode, if available, will change engine and transmission settings to prioritize better fuel economy. Keep in mind, this mode will reduce the car’s performance some, so use it carefully.

Proper Tire Inflation: Make sure your tires are inflated to the pressure the manufacturer recommends. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly, especially when the temperature changes.

Minimize Idling: Avoid idling for too long, because it wastes fuel. If you think you’ll be stopped for more than a minute or two, turn off the engine. Engines now are made to restart quickly.

Regular Maintenance: Keep your Charger SRT maintained well. An engine that is taken care of runs better and uses less fuel. Follow the maintenance schedule for oil changes, air filter replacements, and other services.
