The 2022 Dodge Charger SRT Hellcat Widebody's Real-World Fuel Economy

The 2022 Dodge Charger SRT Hellcat Widebody is powered by a 6.2-liter supercharged V8 engine that produces 797 horsepower. The EPA estimates this vehicle will achieve 12 miles per gallon in the city, 20 miles per gallon on the highway, and 15 miles per gallon combined. These figures explore whether you choose the standard transmission or the eight-speed automatic.

Real-world fuel economy depends heavily on driving habits. Aggressive acceleration, frequent hard braking, and highway speeds above 65 mph will lower your actual mileage. Drivers who maintain steady speeds and avoid rapid acceleration often report fuel economy closer to the EPA highway estimate. Cold weather and short trips around town typically result in numbers closer to the city estimate or lower.

At current fuel prices, you should budget roughly $200 to $250 per week for regular gasoline if you drive this vehicle daily. A full tank holds 18.5 gallons, which means you can expect a driving range of roughly 220 to 370 miles depending on your driving conditions.

Key Takeaways

  • The EPA rates the 2022 Charger SRT Hellcat Widebody at 12 city, 20 highway, and 15 combined miles per gallon.
  • Actual fuel economy will be lower than EPA estimates if you drive aggressively or frequently accelerate hard.
  • The vehicle requires regular unleaded gasoline with an octane rating of 91 or higher.
  • This model produces 797 horsepower and is classified as a full-size muscle car, not a fuel-efficient vehicle.

Emissions Standards and What This Vehicle Meets

The 2022 Dodge Charger SRT Hellcat Widebody meets the EPA Tier 3 emissions standards that were in effect for 2022 model year vehicles. Tier 3 standards limit the amount of nitrogen oxides, particulate matter, and volatile organic compounds that a vehicle can emit. This vehicle also complies with state-level emissions requirements in all 50 states, though some states have stricter standards than others.

The supercharged V8 engine produces higher emissions than smaller, naturally aspirated engines because it burns more fuel and generates more combustion byproducts. The vehicle includes a catalytic converter and oxygen sensors that work together to reduce harmful emissions before they leave the tailpipe. However, this is still a high-performance muscle car, not a low-emissions vehicle.

Fuel Type and Octane Requirements

The 2022 Charger SRT Hellcat Widebody requires premium gasoline with a minimum octane rating of 91. Using regular 87-octane fuel will trigger engine knock, reduce performance, and may cause the engine control computer to adjust timing in ways that damage long-term reliability. Some gas stations label 91-octane fuel as "premium" or "super," while others use different naming conventions — always check the pump label before filling up.

If you live in a high-altitude area above 5,000 feet, you may be able to use 89-octane fuel without problems, but Dodge recommends 91 octane regardless of elevation. Top-tier gasoline brands like Shell, Chevron, and Mobil include detergents that keep fuel injectors clean, which can help maintain fuel economy over time.

How the Supercharger Affects Fuel Consumption

The supercharger is a belt-driven compressor that forces more air into the engine's cylinders, enabling the combustion of more fuel per cycle. This is what allows the engine to produce 797 horsepower. The trade-off is that the supercharger consumes engine power to operate, and the engine must burn significantly more fuel to generate that extra power.

Unlike a turbocharged engine, which uses exhaust gases to spin the turbine, a supercharger draws power directly from the engine's crankshaft. This means the supercharger is always running whenever the engine is running, even at idle or light throttle. The result is consistently poor fuel economy compared to naturally aspirated engines of similar size.

Comparing the Widebody to the Standard Charger SRT Hellcat

The widebody version has the same engine, transmission options, and EPA fuel economy ratings as the standard Charger SRT Hellcat. The widebody package adds wider fenders, a wider track, and upgraded suspension geometry, but these changes do not significantly affect fuel consumption. The main difference is that the widebody version weighs slightly more — approximately 4,570 pounds versus 4,500 pounds for the standard version — but this difference is negligible for fuel economy purposes.

Both versions achieve the same 12 city, 20 highway, and 15 combined miles per gallon. If fuel economy is a concern, the widebody package does not make the situation worse, but it also does not improve it.

Environmental Impact Beyond Fuel Economy

The 2022 Charger SRT Hellcat Widebody produces carbon dioxide emissions as a direct result of burning gasoline. A vehicle that achieves 15 miles per gallon combined will produce roughly 15 tons of CO2 per year if driven 15,000 miles annually. This is significantly higher than sedans and crossovers that achieve 25 to 35 miles per gallon.

The vehicle's manufacturing process, tire production, and eventual recycling also carry environmental costs. However, these upstream and downstream impacts are smaller than the emissions produced during the vehicle's operational life. If environmental impact is a priority, a high-performance muscle car is not the right choice regardless of fuel economy improvements.

Maintenance and Fuel System Care

Regular maintenance helps keep the fuel system clean and the engine running efficiently. Change the engine oil every 10,000 miles using the correct viscosity grade specified in your owner's manual. A clogged fuel filter or dirty fuel injectors can reduce fuel economy by 5 to 10 percent, so using quality gasoline and replacing the fuel filter at the recommended interval matters.

Keep your tires inflated to the pressure listed on the driver's door jamb, not the maximum pressure printed on the tire sidewall. Underinflated tires increase rolling resistance and reduce fuel economy. Check tire pressure monthly and before long trips. A properly maintained engine with clean air filters and correct spark plug gaps will perform closer to EPA estimates than a neglected one.

Frequently Asked Questions

Can I use 87-octane regular fuel instead of 91-octane premium?

Using 87-octane fuel will cause engine knock and trigger the check engine light. The engine's computer will retard timing to prevent damage, which reduces power and fuel economy. Dodge recommends 91 octane, and using lower octane fuel may void your warranty. Always use the fuel grade specified in your owner's manual.

What is the actual driving range on a full tank?

With an 18.5-gallon tank and EPA estimates of 12 to 20 miles per gallon, you can expect a range of roughly 220 miles in the city to 370 miles on the highway. Real-world range depends on your driving style. Aggressive driving will reduce this significantly, while steady highway driving may extend it slightly.

Does the widebody package affect fuel economy compared to the standard Hellcat?

No. Both versions have the same engine, transmission, and EPA fuel economy ratings of 12 city, 20 highway, and 15 combined. The widebody is slightly heavier, but the difference is too small to measurably affect fuel consumption.

How much will fuel cost annually if I drive this car every day?

At 15 miles per gallon combined and 15,000 miles per year, you will use approximately 1,000 gallons of premium gasoline. At current prices ranging from $3 to $4 per gallon, annual fuel costs will range from $3,000 to $4,000. This does not include maintenance, insurance, or registration.

Is there a hybrid or electric version of the Charger SRT Hellcat?

No. The 2022 Charger SRT Hellcat is available only with the supercharged 6.2-liter V8 engine. Dodge has announced plans for electric performance vehicles in future model years, but the current Hellcat lineup remains gasoline-only.
