23 MPG combined isn’t going to win any awards, but in the 2020 Dodge Challenger SXT, it’s almost beside the point. This isn’t a car people buy for Prius-rivalling efficiency. It’s a statement. A slice of American muscle car heritage, albeit one powered by a V6 offering a more sensible compromise than its V8 brethren. This is the entry point to a world of aggressive styling, surprisingly comfortable cruising, and a rumble that hints at something more potent lurking beneath the hood.

City and highway performance

The EPA estimates the 2020 Dodge Challenger SXT with the 3.6L V6 at 19 MPG in the city and 30 MPG on the highway. The city figure reflects the Challenger’s weight and footprint, along with the realities of stop-and-go driving. The V6, while capable, needs to work a bit harder to get this car moving from a standstill. On the open road, however, the Challenger settles into a comfortable and efficient cruise. The 8-speed automatic transmission helps keep the engine in its sweet spot, contributing to that 30 MPG highway number. Drivers who spend a lot of time on interstates will find that the highway figure is reasonably achievable, provided they resist the urge to dip into the throttle too often.

Annual fuel cost

The EPA estimates that the average owner of a 2020 Dodge Challenger SXT will spend $1,900 per year on fuel. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also uses the national average fuel price at the time of the calculation, so your actual costs may vary depending on where you live and how fuel prices fluctuate. Remember that aggressive driving, modifications to the car, and even tire pressure can affect your fuel consumption and, consequently, your annual fuel bill.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Challenger SXT owners report numbers very close to the EPA’s, but it’s highly driver-dependent. Someone with a heavy foot and a penchant for quick acceleration will likely see figures closer to the city rating, even on the highway. Conversely, those who prioritize fuel efficiency by driving conservatively and maintaining a steady speed can often meet or even slightly exceed the EPA’s highway estimate. The Challenger’s computer also provides a running average MPG reading on the dashboard, which can be a useful tool for monitoring your driving habits and their impact on fuel consumption.

How it compares

Compared to other sporty coupes on the market, the Challenger SXT’s fuel economy is in the middle of the pack. The Ford Mustang EcoBoost, for example, achieves a combined EPA rating of 25 MPG, making it a slightly more efficient choice. The Nissan 370Z, a smaller car with a less potent engine, lands around 21 MPG combined. A better comparison may be to the Chevy Camaro 1LS which is rated at 22 MPG combined, very close to the Challenger. For the Challenger buyer, the difference in MPG between these cars is often less important than the Challenger’s iconic styling, spacious interior, and overall persona. They are willing to sacrifice a few MPG for the look and feel of the Dodge. See CHALLENGER MPG across all years.

Tips to maximize efficiency

Gentle acceleration is key. Avoid stomping on the gas pedal, especially from a stop. The Challenger’s weight and engine displacement mean it takes more fuel to get up to speed quickly.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly and inflate them to the factory recommendations.

Minimize idling. Letting your car sit idle for extended periods, whether warming it up in the winter or waiting in a parking lot, wastes fuel. If you’re going to be stopped for more than a minute or two, turn off the engine.

Use cruise control on the highway. Maintaining a steady speed not only improves fuel economy but also reduces wear and tear on your vehicle. Engaging cruise control on long highway drives can help you achieve those EPA numbers.

Consider lighter wheels and tires when it’s time for replacement. Lower rolling resistance replacement tires, and lightweight wheels will help reduce rotational mass, which means it requires less energy to accelerate and maintain speed.
