What the 2015 Dodge Charger offers in fuel economy and emissions

The 2015 Dodge Charger comes in five engine choices, each with different fuel economy and emissions ratings. The base model uses a 3.6-liter V6 that gets 25 miles per gallon on the highway and 16 in the city with rear-wheel drive. The most common upgrade is the 5.7-liter V8, which drops to 23 highway and 15 city. If you choose all-wheel drive, fuel economy decreases by 1 to 2 miles per gallon across the board. Two higher-performance V8 options—the 5.7-liter with 370 horsepower and the 6.4-liter with 470 horsepower—have the same fuel economy as the standard 5.7-liter, though the 6.4-liter is only available in the R/T and SRT models.

All 2015 Chargers meet current EPA emissions standards. The V6 produces lower nitrogen oxide and particulate emissions than the V8 models, which matters if you live in an area with strict emissions testing. The V8 engines produce more emissions overall but still pass federal requirements. Dodge does not offer a hybrid or plug-in hybrid version of the Charger in 2015.

Key Takeaways

  • The 2015 Charger V6 achieves 25 highway and 16 city miles per gallon, while V8 models get 23 highway and 15 city.
  • All-wheel drive reduces fuel economy by 1 to 2 miles per gallon compared to rear-wheel drive on any engine.
  • The V6 produces lower emissions than the V8 options and may be required in areas with strict emissions testing.
  • The 6.4-liter V8 (SRT model) offers the most power but the same fuel economy as the standard 5.7-liter V8.

Engine choices and what they mean for your fuel costs

Choosing between the V6 and V8 is the biggest decision for fuel economy. At 15,000 miles per year and an average gas price of $2.50 per gallon, a V6 rear-wheel-drive Charger costs roughly $1,500 annually in fuel, while a V8 rear-wheel-drive model costs about $1,630. That $130 difference compounds over time, but the V8 offers significantly more horsepower (370 versus 292) if performance matters to you.

All-wheel drive adds roughly $100 to $150 per year in fuel costs compared to rear-wheel drive, depending on which engine you choose. The difference is most noticeable in the V6, where all-wheel drive drops fuel economy from 25 to 23 highway miles per gallon. If you live in a region with heavy snow or need better traction in wet conditions, the cost may be worth it; otherwise, rear-wheel drive saves money at the pump.

Emissions testing and what your 2015 Charger needs to pass

The 2015 Dodge Charger passes federal EPA emissions standards in all fifty states. However, some states and counties run stricter emissions tests than federal law requires. California, New York, Massachusetts, and several other states have their own emissions programs. If you live in one of these areas, your Charger must pass that state's test, not just the federal standard.

The V6 engine is more likely to pass strict state emissions tests on the first try because it produces lower nitrogen oxide levels than the V8. If you live in a state with emissions testing and already own a V8 Charger, you can still pass—the V8 meets all federal standards—but you should have the emissions system checked before your test date. A faulty oxygen sensor or catalytic converter can cause a V8 to fail even if the engine itself is sound.

Real-world fuel economy versus EPA ratings

EPA ratings assume a mix of highway and city driving under controlled conditions. Most 2015 Charger owners report fuel economy 1 to 3 miles per gallon lower than the EPA estimate, especially if they drive mostly in the city or in stop-and-go traffic. Highway driving at steady speeds gets you closer to the EPA number. Aggressive acceleration, towing, or driving in mountainous terrain will lower fuel economy further.

Maintenance also affects fuel economy. A clogged air filter, worn spark plugs, or low tire pressure can each reduce miles per gallon by 1 to 3 percent. Keeping your Charger properly maintained—regular oil changes, correct tire pressure, and timely spark plug replacement—helps you stay closer to the EPA estimate.

Transmission type and fuel economy differences

All 2015 Dodge Chargers use an eight-speed automatic transmission. There is no manual option and no continuously variable transmission (CVT). The eight-speed is designed to keep the engine in its most efficient operating range during highway driving, which is why highway fuel economy is noticeably better than city fuel economy across all models.

The transmission itself does not vary between engine choices—a V6 and a V8 Charger use the same gearbox. The difference in fuel economy comes entirely from the engine size and power output. The eight-speed transmission is reliable and does not require special maintenance beyond regular fluid checks.

Comparing the 2015 Charger to other midsize sedans

The 2015 Charger's fuel economy is lower than most midsize sedans because it is heavier and more powerful. A 2015 Toyota Camry with a V6 gets 28 highway and 18 city miles per gallon. A 2015 Chevrolet Impala with a V6 gets 29 highway and 19 city. The Charger prioritizes performance and interior space over fuel efficiency, which is why it uses more gas.

If fuel economy is your primary concern, a smaller sedan or a hybrid will serve you better. If you want a full-size sedan with V8 power and performance, the Charger's fuel economy is competitive with other V8 sedans like the Chrysler 300 and Dodge Magnum (discontinued in 2008). The trade-off between power and efficiency is the core choice when buying a Charger.

Frequently Asked Questions

Does the 2015 Charger have a hybrid option?

No. Dodge does not offer a hybrid or plug-in hybrid version of the Charger in 2015. Your only options are the gasoline V6 and V8 engines. If you want a hybrid midsize sedan, you would need to look at other manufacturers like Toyota or Honda.

Will my 2015 Charger pass emissions testing in California?

Yes, all 2015 Chargers meet California's emissions standards. The V6 is slightly more likely to pass on the first try because it produces lower nitrogen oxide emissions, but both the V6 and V8 are designed to pass California's test. Have your emissions system inspected before your test date if you have not had recent maintenance.

What is the difference in fuel economy between rear-wheel drive and all-wheel drive?

All-wheel drive reduces fuel economy by 1 to 2 miles per gallon across all engine options. A V6 rear-wheel-drive Charger gets 25 highway miles per gallon, while the same model with all-wheel drive gets 23. The difference is smaller in the V8 but still measurable.

Can I improve my 2015 Charger's fuel economy after I buy it?

You can improve fuel economy by 1 to 3 percent through maintenance: keep your tires at the correct pressure, replace air filters on schedule, and use the recommended grade of motor oil. Driving habits matter too—steady highway speeds use less fuel than aggressive city driving. You cannot significantly change the EPA rating itself without modifying the engine.

Is the V6 Charger underpowered compared to the V8?

The V6 produces 292 horsepower versus 370 in the standard V8. For daily driving and highway merging, the V6 is adequate. If you want faster acceleration or plan to tow, the V8 is noticeably more capable. The V6 saves money on fuel and maintenance, while the V8 offers more performance.
