Engine Options and Fuel Economy for the 2013 Dodge Charger

The 2013 Dodge Charger came with three engine choices, each with different fuel consumption rates. The base model used a 3.6-liter V6 engine that produced 292 horsepower and achieved an EPA-estimated 25 miles per gallon on the highway and 16 miles per gallon in the city. The mid-range option was a 5.7-liter V8 that generated 370 horsepower but consumed more fuel, with ratings of 23 mpg highway and 14 mpg city. The high-performance R/T model also used the 5.7-liter V8 but with slightly different tuning.

A third engine option, the 6.4-liter V8 in the SRT8 model, delivered 470 horsepower but had the lowest fuel economy of the lineup. That engine was rated at 22 mpg highway and 13 mpg city. All three engines used regular unleaded gasoline, though the SRT8 could run on premium fuel for optimal performance. Combined fuel economy (averaging city and highway driving) ranged from approximately 18 mpg for the V6 to 17 mpg for the larger V8 engines.

Key Takeaways

  • The 2013 Charger offered three engines: a 3.6L V6 (25 highway/16 city mpg), a 5.7L V8 (23 highway/14 city mpg), and a 6.4L V8 in the SRT8 (22 highway/13 city mpg).
  • The V6 engine was the most fuel-efficient option and suitable for drivers prioritizing economy over performance.
  • Both V8 engines produced significantly more power but consumed considerably more fuel, particularly in city driving.
  • Real-world fuel economy often varies from EPA estimates depending on driving habits, road conditions, and vehicle maintenance.
  • The 2013 model year predates modern efficiency standards, so fuel consumption is higher than comparable vehicles built after 2015.

Emissions Standards and Compliance

The 2013 Dodge Charger met the emissions standards in effect for that model year under the Environmental Protection Agency (EPA) regulations. All three engine options were equipped with catalytic converters and emissions control systems designed to reduce nitrogen oxides, particulate matter, and volatile organic compounds. The vehicle carried a Tier 2 emissions rating, which was the federal standard for passenger cars at that time.

The Charger's emissions control system included a three-way catalytic converter, oxygen sensors, and an evaporative emissions control system to capture fuel vapors. These components worked together to minimize harmful pollutants released into the atmosphere. The vehicle also had to pass a smog check in states that required it, which tested tailpipe emissions for carbon monoxide and nitrogen oxides.

Transmission and Drivetrain Impact on Fuel Use

The 2013 Charger came standard with a five-speed automatic transmission on the V6 model and a five-speed automatic on the V8 models. The transmission type directly affected fuel economy because automatic transmissions with fewer gears typically consume more fuel than modern eight- or ten-speed units. The five-speed design was common in 2013 but is now considered outdated by current efficiency standards.

All 2013 Chargers used rear-wheel drive, which added weight and rotating mass compared to front-wheel-drive vehicles. This drivetrain configuration contributed to the relatively modest fuel economy figures across all three engine options. The vehicle's curb weight ranged from approximately 3,600 pounds for the V6 to over 4,000 pounds for the SRT8, and heavier vehicles require more fuel to accelerate and maintain speed.

Comparing the 2013 Charger to Other Sedans of That Era

The 2013 Charger's fuel economy was typical for full-size performance sedans of that time period. A 2013 Chevrolet Impala with a V6 achieved similar highway mileage (25 mpg) but slightly better city mileage (17 mpg). The 2013 Chrysler 300 with a V8 engine posted nearly identical numbers to the Charger's V8 models. Compact sedans like the 2013 Honda Accord V6 achieved 31 mpg highway and 21 mpg city, demonstrating the significant fuel economy gap between mid-size and full-size vehicles.

Compared to modern sedans, the 2013 Charger consumed considerably more fuel. A current-generation Dodge Charger with a similar V8 engine achieves approximately 28 mpg highway and 18 mpg city, representing roughly a 20 percent improvement in efficiency. This difference reflects advances in engine technology, transmission design, aerodynamics, and weight reduction over the past decade.

Maintenance and Emissions System Care

Keeping the 2013 Charger's emissions systems in good working order helps maintain fuel economy and reduce pollution. The oxygen sensors, which monitor exhaust composition, should be inspected during regular service intervals. A faulty oxygen sensor can cause the engine to run rich (using more fuel than necessary) and trigger a check engine light. The catalytic converter should be inspected for physical damage or internal degradation, as a failing converter reduces engine efficiency.

Regular oil changes, air filter replacements, and fuel system cleaning support optimal engine performance and fuel consumption. A clogged air filter forces the engine to work harder and consume more fuel. Using the manufacturer's recommended grade of motor oil (typically 5W-20 for the 2013 Charger) ensures proper engine lubrication and efficiency. Tire pressure also affects fuel economy—underinflated tires increase rolling resistance and reduce mpg by up to 3 percent.

Understanding EPA Ratings and Real-World Differences

The EPA fuel economy numbers printed on the window sticker represent laboratory test results under controlled conditions. The EPA tests vehicles on a dynamometer (a machine that simulates driving) using standardized driving patterns that may not reflect your actual driving. Real-world fuel economy for a 2013 Charger often falls 10 to 20 percent below the EPA highway estimate, particularly if you drive in stop-and-go city traffic or at high speeds.

Factors that reduce real-world fuel economy include aggressive acceleration, frequent braking, idling, cold weather (which thickens oil and reduces engine efficiency), and carrying heavy cargo. Conversely, steady highway driving at moderate speeds, proper tire inflation, and a well-maintained engine can help achieve or occasionally exceed EPA estimates. Tracking your fuel consumption over several fill-ups gives you a realistic picture of what your specific vehicle actually achieves.

Frequently Asked Questions

What does the EPA rating on a 2013 Charger window sticker actually mean?

The EPA rating shows fuel economy measured in a laboratory under standardized conditions. It represents a reasonable estimate but not a may provide of what you will see at the pump. Your actual mileage depends on driving habits, road conditions, vehicle maintenance, and weather. Most drivers report real-world economy 10 to 20 percent lower than the highway estimate.

Can I improve fuel economy on a 2013 Charger with modifications?

Certain maintenance steps help: keeping tires properly inflated, using the manufacturer's recommended motor oil grade, replacing a clogged air filter, and ensuring the oxygen sensors work correctly. Driving habits matter more than modifications—steady acceleration, moderate speeds, and avoiding idling improve economy significantly. Aftermarket modifications like lowering springs or performance exhaust systems typically reduce fuel economy rather than improve it.

Is the 2013 Charger V6 significantly more fuel-efficient than the V8 models?

Yes. The V6 achieves approximately 25 mpg highway versus 23 mpg for the V8 models—a difference of about 8 percent. In city driving, the gap widens: the V6 gets 16 mpg city while the V8 gets 14 mpg city. Over a year of typical driving, this translates to roughly 200 to 300 fewer gallons of fuel consumed with the V6, depending on your annual mileage.

What emissions standard did the 2013 Charger meet?

The 2013 Charger met EPA Tier 2 emissions standards, which were the federal requirement for that model year. All three engine options included catalytic converters, oxygen sensors, and evaporative emissions controls. The vehicle could pass a smog check in states that required one, provided the emissions systems were functioning correctly.

How does a 2013 Charger's fuel economy compare to newer sedans?

Modern sedans are significantly more efficient. A current Dodge Charger V8 achieves roughly 28 mpg highway compared to 23 mpg for the 2013 model—about a 20 percent improvement. This reflects advances in engine technology, transmission design (modern cars use eight- to ten-speed automatics versus five-speed), and lighter materials. Hybrid and electric sedans achieve 40+ mpg equivalent.
