15 MPG combined isn’t going to win any eco-awards, but let’s be honest: nobody buys a 2022 Dodge Challenger SRT Widebody expecting Prius-like fuel efficiency. This is a car bred for tire-shredding launches, quarter-mile domination, and broadcasting its presence with a thunderous exhaust note. Fuel economy is simply the price of admission to the exclusive club of high-horsepower American muscle.

City and highway performance

The EPA estimates the Challenger SRT Widebody at 13 MPG in the city and 21 MPG on the highway. The disparity comes down to how the 6.2L supercharged HEMI V8 is used. City driving involves constant stop-and-go, requiring frequent bursts of acceleration that tap into the engine’s immense power. The heavy curb weight of the Widebody (over 4,400 pounds) also contributes to lower city MPG. On the highway, with consistent speeds, the engine loafs along, resulting in the relatively better, but still modest, 21 MPG figure.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,850 for the 2022 Dodge Challenger SRT Widebody. This figure is based on driving 15,000 miles per year and using national average fuel prices. Expect this number to fluctuate wildly depending on the prevailing gas prices in your area, and more importantly, your driving habits. Frequent trips to the drag strip will inflate that number significantly.

Real-world expectations

While the EPA numbers provide a benchmark, your real-world fuel economy will depend heavily on your driving style. Those with a heavy right foot will likely see numbers significantly lower than the EPA estimates. Drivers who adopt a more relaxed approach and prioritize highway cruising might achieve slightly better fuel economy. But let’s be real: restraint is not a virtue typically associated with Challenger SRT Widebody owners. They buy the car to experience its power, not to set MPG records.

How it compares

Compared to its direct rivals, the Challenger SRT Widebody is generally thirstier. A 2022 Ford Mustang Shelby GT500, while equally potent, manages a slightly better 14 MPG city and 22 MPG highway. The Chevrolet Camaro ZL1, another supercharged V8 competitor, achieves an EPA-estimated 14 MPG city and 20 MPG highway. These differences, while seemingly minor, can add up over time. However, buyers choosing between these cars aren’t solely focused on fuel economy; they’re weighing performance, styling, and brand loyalty.

Tips to maximize efficiency

While extracting maximum MPG from a Challenger SRT Widebody might seem counterintuitive, there are a few strategies you can employ. First, resist the urge to constantly accelerate hard. Gentle acceleration and smooth throttle inputs will significantly reduce fuel consumption. The supercharger is happiest when you’re not asking it to work.

Use the Challenger’s drive modes. Selecting “Eco” mode softens throttle response and optimizes the transmission for fuel efficiency. It won’t transform the Challenger into a fuel sipper, but it can make a noticeable difference in everyday driving. Just remember to switch back to “Track” mode when the occasion calls for it.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively affects fuel economy. Check your tire pressures regularly and maintain them at the recommended levels listed on the door jamb.

Avoid unnecessary idling. Letting the engine idle for extended periods consumes fuel without moving the car. If you’re stopped for more than a minute or two, turn off the engine. This is especially true in the Challenger SRT Widebody, where the large displacement engine burns a considerable amount of fuel at idle.

Plan your routes strategically. Minimize stop-and-go traffic by choosing routes with fewer intersections and traffic lights. Highway driving generally yields better fuel economy than city driving, so opt for the freeway when possible, even if it adds a few miles to your trip. Your fuel bill will thank you.
