The Charger R/T is a high-performance muscle car with a V8 engine and significant fuel consumption

The Dodge Charger R/T is a four-door sedan powered by a V8 engine, built for speed and acceleration rather than fuel economy. The "R/T" stands for "Road and Track," Dodge's designation for their performance models. If you own one or are considering buying one, understanding its environmental footprint — particularly its fuel use and emissions — matters for your budget and for the air quality in your community.

The Charger R/T burns more gasoline than most sedans on the road. Depending on the model year and driving conditions, you can expect fuel economy in the range of 15 to 18 miles per gallon combined (city and highway driving). That means filling up more often and spending more on gas than you would with a standard sedan or hybrid vehicle.

Because it burns more fuel, the Charger R/T also produces more carbon dioxide and other tailpipe emissions per mile driven. These emissions contribute to climate change and local air pollution. If environmental impact is a concern for you, this is one of the trade-offs of owning a performance vehicle.

Key Takeaways

  • The Charger R/T gets roughly 15 to 18 miles per gallon depending on how and where you drive, which is lower than most other sedans.
  • V8 engines produce higher tailpipe emissions of carbon dioxide and nitrogen oxides, affecting both climate and local air quality.
  • Fuel costs for a Charger R/T are significantly higher than for a four-cylinder sedan or hybrid vehicle over the same distance.
  • Regular maintenance — oil changes, air filter replacement, and proper tire pressure — can help the engine run as efficiently as possible.
  • Some states offer tax incentives or rebates for trading in older, high-emission vehicles, which may offset the cost of switching to a more efficient car.

How the V8 engine affects fuel consumption

The Charger R/T's 5.7-liter V8 engine has eight cylinders firing in sequence, which requires more fuel to produce the horsepower and torque the car is designed for. A V8 straightforward burns more gasoline per mile than a four-cylinder or six-cylinder engine, all else being equal. This is not a flaw — it is the trade-off built into the design.

Real-world fuel economy depends heavily on how you drive. Highway driving at steady speeds produces better mileage than city driving with frequent stops and starts. Aggressive acceleration, towing, and driving in cold weather all reduce fuel economy further. If you drive a Charger R/T mostly on highways at moderate speeds, you may see mileage closer to 18 to 20 mpg. If you drive in stop-and-go city traffic or accelerate hard regularly, expect closer to 14 to 16 mpg.

Emissions from the Charger R/T and what they mean

The Charger R/T produces two main categories of emissions: greenhouse gases (primarily carbon dioxide) and criteria pollutants (nitrogen oxides and particulate matter). Carbon dioxide traps heat in the atmosphere and contributes to climate change. Nitrogen oxides and particulate matter damage air quality and can cause respiratory problems, especially in children and people with asthma.

The amount of each pollutant depends on the model year. Newer Charger R/T models (2015 and later) have emissions controls that reduce nitrogen oxides and particulate matter compared to older models, but they still emit more per mile than smaller, more efficient vehicles. A 2020 Charger R/T produces roughly twice the carbon dioxide per mile as a comparable four-cylinder sedan.

Maintenance steps that preserve fuel economy

You cannot change the engine size, but you can keep it running as efficiently as the design allows. Check your tire pressure monthly — underinflated tires increase rolling resistance and reduce fuel economy by 1 to 3 percent. Replace the engine air filter according to your owner's manual, usually every 15,000 to 30,000 miles. A clogged filter forces the engine to work harder.

Keep up with oil changes using the grade specified in your manual. Synthetic oil often flows more easily than conventional oil, which can improve fuel economy slightly. Avoid carrying unnecessary weight in the trunk, and remove roof racks or cargo carriers when you are not using them. These small steps add up, especially over thousands of miles.

Comparing the Charger R/T to other vehicles

If fuel economy and emissions are priorities, a four-cylinder sedan or hybrid will cost you significantly less to operate. A Honda Accord or Toyota Camry gets 28 to 32 mpg combined and produces roughly half the carbon dioxide per mile. A hybrid like the Toyota Prius gets 50+ mpg and produces even less. Over 100,000 miles, the fuel cost difference between a Charger R/T and a Prius can exceed $10,000.

That said, the Charger R/T offers performance and driving experience that efficiency-focused vehicles do not. The choice depends on what matters most to you: operating cost and environmental impact, or power and acceleration. There is no universally "right" answer — only the answer that fits your priorities and budget.

State incentives for trading in high-emission vehicles

Several states offer rebates or tax credits if you trade in an older, high-emission vehicle for a newer, more efficient one. California, New York, and Colorado have programs that vary in structure and funding. Some offer direct rebates; others offer tax credits. may be able to access usually depends on the age and emissions rating of the vehicle you are trading in, not on the vehicle you buy.

If you own an older Charger R/T and are considering switching to a more efficient vehicle, check your state's environmental agency website or search "[your state] vehicle trade-in incentive" to see what programs exist. Funding for these programs changes year to year, so availability is not may provide.

Frequently Asked Questions

What is the actual fuel economy of a Charger R/T?

Most Charger R/T models get 15 to 18 miles per gallon combined, depending on the model year and how you drive. Highway driving produces better mileage than city driving. Check your specific model year's EPA rating on fueleconomy.gov for the most accurate figure.

Does a Charger R/T produce more emissions than a regular sedan?

Yes. The V8 engine burns more fuel per mile, which means more carbon dioxide and other pollutants per mile driven. A Charger R/T produces roughly twice the carbon dioxide per mile as a four-cylinder sedan of similar size.

Can I improve the fuel economy of my Charger R/T?

You can improve it slightly through maintenance: keep tires properly inflated, replace air filters on schedule, use the correct oil grade, and avoid carrying unnecessary weight. These steps may improve economy by 2 to 5 percent, but the engine size itself is the primary factor.

Is the Charger R/T worth the fuel cost?

That depends on your priorities. If performance and driving experience are important to you, the higher fuel cost may be worth it. If fuel economy and environmental impact are priorities, a four-cylinder or hybrid sedan will cost significantly less to operate over time.
