15 MPG combined is not a typo. The 2021 Dodge Charger SRT Widebody, specifically packing the 6.2L supercharged HEMI V8, is unapologetically thirsty. Anyone signing on the dotted line for this modern muscle car knows exactly what they’re getting into. This isn’t about squeezing every last mile from a gallon; it’s about raw power, aggressive styling, and a sound that makes the ground tremble. Efficiency is simply not part of the equation.

City and highway performance

Those EPA estimates break down to a dismal 12 MPG in the city and a marginally better 21 MPG on the highway. The city figure reflects the brutality of stop-and-go traffic when harnessed to 707 horsepower and a heavy right foot. The temptation to unleash the supercharger’s fury at every green light takes a substantial toll. The 21 MPG highway figure is achievable if one practices extreme restraint, but let’s be honest, the Widebody begs to stretch its legs. The eight-speed automatic transmission does its best to manage the power, but ultimately, physics and the sheer displacement of that Hemi dictate the outcome.

Annual Fuel Cost

According to the EPA, the estimated annual fuel cost for the 2021 Dodge Charger SRT Widebody 6.2L is a hefty $3,850. This figure is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which this beast requires. Considering that many owners will likely exceed 15,000 miles, especially on weekend cruises and track days, the actual cost will likely be much higher. Prospective buyers should carefully consider this significant expense when budgeting for ownership: gas is an expense you can’t avoid.

Real-World Expectations

The EPA numbers are optimistic in real-world scenarios. Expect to see even lower numbers during spirited driving or frequent short trips. Enthusiasts who frequent the drag strip or participate in high-performance driving events will see their fuel economy plummet into the single digits. Even casual drivers using the Charger SRT Widebody as a daily driver are unlikely to see numbers that mirror the EPA figures. Consider it a price to pay for the privilege of piloting a supercharged American icon. Learn more information about CHARGER MPG across all years.

How it compares

Compared to other performance sedans, the Charger SRT Widebody is an outlier when it comes to fuel economy. The BMW M5 Competition, for example, manages 17 MPG combined, a notable improvement thanks to its smaller displacement and advanced engine technology. Even the Cadillac CT5-V Blackwing, another supercharged V8 monster, ekes out around 15 MPG combined as well. A similarly styled option like the Chrysler 300C with the 5.7-liter V8 lands closer to 19 MPG combined. For those prioritizing raw horsepower above all else, the Charger’s penalty at the pump will be a worthwhile trade-off. Explore all Dodge fuel economy data.

Tips to maximize efficiency

While fuel efficiency might not be top of mind for Charger SRT Widebody owners, there are a few techniques to potentially improve MPG by a small margin. First, consciously modulate your right foot. Avoiding aggressive acceleration and maintaining a steady speed on the highway will save some fuel over time. Try to resist flooring it off every stop light, as tempting as it is.

Premium fuel is required to unlock maximum performance, ensure that you are using the recommended octane rating from the owner’s manual. Using lower octane fuel can negatively impact efficiency and even damage the engine over time. Consider your driving mode, if equipped. Some models have an “Eco” or “Street” mode that relaxes the throttle response and shift points, which makes driving more practical for gas savings.

Properly inflated tires are critical for optimal fuel economy. Check your tire pressure regularly and ensure it matches the manufacturer’s recommended specifications in the owner’s manual or the sticker on the driver’s side doorjamb. Underinflated tires create more rolling resistance, which reduces fuel efficiency.

Ensure the vehicle is properly maintained. Regular servicing, including oil changes, air filter replacements, and spark plug replacements, ensures the engine is running efficiently. A well-maintained engine will always perform better and conserve fuel compared to a neglected one.
