What the 2014 Dodge Charger's Fuel Economy Actually Is

The 2014 Dodge Charger gets between 16 to 25 miles per gallon depending on the engine and transmission you have. The base V8 model with a manual transmission averages around 16 city / 25 highway. The V8 with an automatic transmission drops to roughly 16 city / 24 highway. If you have the optional 3.6-liter V6, you'll see better numbers: approximately 18 city / 27 highway with the automatic.

These figures come from the EPA's official testing, though your actual mileage will vary based on how you drive, road conditions, and maintenance. Highway driving typically yields better fuel economy than city driving because the engine runs at a steadier RPM without frequent acceleration and braking.

The 2014 Charger is a full-size sedan, and fuel economy at this level reflects that weight and engine power. If fuel costs are a major concern for your situation, the V6 option will noticeably reduce what you spend at the pump compared to either V8 choice.

Key Takeaways

  • The 2014 Charger's fuel economy ranges from 16 to 25 mpg depending on engine size and transmission type, with the V6 offering the best efficiency.
  • EPA estimates assume mixed driving; your actual mileage depends on your driving habits, traffic patterns, and how well you maintain the vehicle.
  • The Charger produces emissions that meet 2014 EPA standards, which were less stringent than current regulations.
  • Keeping up with scheduled maintenance—especially oil changes and air filter replacements—helps the engine run at its rated efficiency.
  • The Charger's weight and engine displacement mean it will never achieve the fuel economy of smaller, lighter vehicles.

EPA Emissions Standards the 2014 Charger Meets

The 2014 Dodge Charger was built to meet the EPA's Tier 2 emissions standards that were in effect at that time. These standards set limits on nitrogen oxides (NOx), particulate matter, and other pollutants that come out of the tailpipe. The Charger also includes an onboard diagnostic system (OBD-II) that monitors whether the emissions control equipment is working properly.

If the check engine light comes on, it usually means one of the emissions sensors has detected a problem—often something straightforward like a loose gas cap, but sometimes a more serious issue with the catalytic converter or oxygen sensors. Getting this checked promptly keeps the vehicle running efficiently and helps it stay within emissions limits.

The 2014 standards were significantly less strict than the regulations that explore to new vehicles today. A 2014 Charger will produce more emissions per mile than a new model, but it still meets the legal requirements that were set when it was manufactured.

Fuel Type and Tank Capacity

The 2014 Charger runs on regular unleaded gasoline (87 octane). You do not need premium fuel unless your specific model has a high-compression engine option, which would be noted in your owner's manual. Using the correct octane rating keeps the engine running smoothly and prevents knocking.

The fuel tank holds 18.0 gallons. With the V6 engine, that gives you a theoretical range of around 486 miles on a full tank at highway fuel economy. With the V8, expect closer to 432 miles. In real-world driving with mixed city and highway, you'll typically get 350 to 420 miles per tank depending on your driving patterns.

The fuel door is on the driver's side of the vehicle. When you pull up to a pump, make sure you're at a station with pumps on that side, or you'll need to back in or use a different pump.

How the Charger's Engine Size Affects Emissions and Efficiency

The 2014 Charger came with two main engine choices: a 3.6-liter V6 and a 5.7-liter V8. Engine displacement—measured in liters—directly affects both fuel consumption and emissions output. The larger the engine, the more fuel it burns and the more emissions it produces per mile driven.

The V6 produces roughly 292 horsepower and burns less fuel because it has smaller cylinders and lower displacement. The V8 produces 370 horsepower but requires significantly more fuel to generate that extra power. If you're comparing two 2014 Chargers, the V6 owner will spend less on gas and produce fewer total emissions over the same distance.

Engine size is a trade-off: more power means more fuel consumption. There's no way around this with a vehicle of the Charger's size and weight. If you're buying used and fuel economy matters, the V6 is the clear choice.

Maintenance That Keeps Emissions and Fuel Economy in Check

Regular maintenance directly affects how efficiently your 2014 Charger runs and how much it pollutes. The most important items are oil changes (every 3,000 to 5,000 miles depending on oil type), air filter replacements (typically every 15,000 to 30,000 miles), and spark plug replacements (usually around 30,000 miles for the Charger).

A clogged air filter makes the engine work harder and burn more fuel. Worn spark plugs cause misfires, which waste fuel and increase emissions. Dirty oil increases friction inside the engine, which also reduces efficiency. Keeping these items current is one of the few things you directly control that affects both your fuel costs and your vehicle's environmental impact.

If your check engine light is on, have it scanned for codes before assuming it's a major problem. Many emissions-related codes point to straightforward fixes like a faulty oxygen sensor or a loose gas cap, both of which are inexpensive to address.

Real-World Fuel Economy vs. EPA Estimates

EPA numbers are tested under controlled conditions on a dynamometer, not on actual roads. Your real-world fuel economy will almost always be lower than the highway estimate and often lower than the combined estimate. Aggressive acceleration, frequent braking, idling in traffic, and driving on hilly terrain all reduce efficiency.

Cold weather also hurts fuel economy because the engine takes longer to reach operating temperature and the fuel doesn't burn as efficiently. Winter driving can reduce your mpg by 10 to 20 percent compared to summer. Tire pressure matters too—underinflated tires increase rolling resistance and force the engine to work harder.

If you're tracking your fuel economy and it's significantly worse than expected, check your tire pressure first, then have the vehicle scanned for emissions codes. A sudden drop in efficiency often signals a problem with the oxygen sensors or fuel injectors.

Comparing the 2014 Charger to Other Full-Size Sedans

The 2014 Charger's fuel economy is typical for a full-size performance sedan of that era. A 2014 Chrysler 300 with a V8 gets similar numbers. A 2014 Chevrolet Impala with a V8 also falls in the same range. If you're comparing to a 2014 Toyota Camry or Honda Accord, those smaller sedans will get noticeably better fuel economy—often 5 to 8 mpg better—because they weigh less and have smaller engines.

The Charger was designed as a performance vehicle first, not an economy car. You're trading fuel efficiency for power and size. If your primary concern is minimizing fuel costs, a mid-size sedan will serve you better. If you want the Charger's performance and don't mind the fuel consumption, that's a legitimate choice—just go in with realistic expectations about what you'll spend at the pump.

Used 2014 Chargers are widely available, and parts are inexpensive because Dodge produced them in large numbers. That affordability sometimes makes the higher fuel costs worth it to buyers who value the vehicle's style and performance.

Frequently Asked Questions

Does the 2014 Charger have a hybrid or electric option?

No. Dodge did not offer a hybrid or electric version of the Charger in 2014. Your only choices were the V6 or V8 gasoline engines. If fuel economy is your top priority, the V6 is your best option with this model year.

What happens if I use premium gas in a 2014 Charger that takes regular?

Nothing harmful will happen. Premium gas will straightforward cost you more money without any benefit. Use the octane rating specified in your owner's manual. For most 2014 Chargers, that's 87 octane regular unleaded.

Can I improve my 2014 Charger's fuel economy with modifications?

Minor improvements are possible through maintenance and driving habits—keeping tires properly inflated, removing excess weight, and avoiding aggressive acceleration. Aftermarket modifications like cold air intakes or tuning chips may claim to improve economy, but results are typically minimal and often void your warranty.

How do I know if my Charger's emissions system is failing?

The check engine light is your first warning. Have the vehicle scanned for diagnostic trouble codes at a repair shop or auto parts store. Common emissions failures include faulty oxygen sensors, a failing catalytic converter, or a loose gas cap. The code will tell you which component needs attention.

Is a 2014 Charger legal to drive in states with strict emissions testing?

Yes, as long as it passes your state's emissions test. The 2014 Charger meets the EPA standards that were in effect when it was built. Some states have stricter testing than others, but a well-maintained 2014 Charger should pass in most places. If it fails, the diagnostic code will identify what needs to be repaired.
