What the 2014 Dodge Charger offers in fuel economy and emissions

The 2014 Dodge Charger comes with three engine choices, each with different fuel consumption and emissions profiles. The base model uses a 3.6-liter V6 that delivers 25 miles per gallon on the highway and 16 in the city. The mid-range 5.7-liter V8 gets 23 highway and 15 city. The high-performance 6.4-liter V8 (SRT model) achieves 23 highway and 14 city. All three engines run on regular unleaded gasoline.

The 2014 Charger meets the emissions standards that were in effect for that model year. The vehicle's catalytic converter and emissions control systems are designed to reduce nitrogen oxides and particulate matter. If you are checking emissions compliance for registration or inspection purposes, your state's environmental agency will have the specific standards your vehicle must meet.

Key Takeaways

  • The 2014 Charger V6 achieves 25 mpg highway and 16 mpg city, while the V8 models range from 23 to 15 mpg depending on driving conditions.
  • All three engine options run on regular unleaded gasoline with no special fuel requirements.
  • The vehicle meets 2014 federal emissions standards through its catalytic converter and emissions control systems.
  • Actual fuel economy varies based on driving habits, road conditions, and whether the transmission is automatic or manual.

Engine options and their fuel consumption differences

The 3.6-liter V6 is the most fuel-efficient choice for the 2014 Charger. It produces 292 horsepower and is paired with a five-speed automatic transmission. This engine is the standard option and represents the best balance between performance and fuel economy for drivers who prioritize lower fuel costs.

The 5.7-liter V8 produces 370 horsepower and comes with either a five-speed automatic or a manual transmission. This engine is found in the R/T trim level and offers noticeably more power than the V6, though fuel consumption increases slightly. The manual transmission version may see slightly different fuel economy numbers than the automatic.

The 6.4-liter V8 is exclusive to the SRT model and produces 470 horsepower. This engine delivers the highest performance but also the lowest fuel economy of the three options. The SRT model is designed for drivers prioritizing acceleration and handling over fuel efficiency.

Real-world fuel economy versus EPA estimates

EPA estimates represent laboratory testing conditions and do not always match what drivers experience on the road. Factors that lower your actual fuel economy include frequent city driving with traffic lights and stops, aggressive acceleration, towing, and driving in cold weather. Highway driving at steady speeds typically produces results closer to the EPA highway estimate.

Maintenance also affects fuel economy. A clogged air filter, worn spark plugs, or low tire pressure can reduce efficiency by several miles per gallon. If your 2014 Charger is getting noticeably worse mileage than the EPA estimates suggest, checking these items is a reasonable first step.

Emissions testing and registration requirements

Whether your 2014 Charger must pass an emissions test depends on your state and local regulations. Some states require testing every two years, others every year, and some do not require it at all. Your state's environmental or motor vehicle agency website will specify the testing schedule for your area and vehicle type.

The 2014 model year is now over a decade old, so it may be subject to different testing standards than newer vehicles in some states. If your vehicle fails an emissions test, a certified mechanic can diagnose whether the issue is a faulty oxygen sensor, a problem with the catalytic converter, or another emissions system component. Repairs are typically required before the vehicle can be registered.

Fuel type and octane requirements

All three 2014 Charger engines are designed to run on regular unleaded gasoline (87 octane). Using premium fuel (91 or 93 octane) will not improve performance or fuel economy in the V6 or standard V8 models, though some drivers use it anyway without harm. The SRT model's 6.4-liter engine can run on regular fuel but is tuned to perform better on premium, so using premium may provide slightly better performance if you choose to do so.

Ethanol blends up to 10 percent (E10) are standard in most gasoline sold in the United States and are compatible with the 2014 Charger. Higher ethanol blends (E15 or E85) are not recommended unless your owner's manual specifically states compatibility, which it does not for this model year.

Maintenance that affects emissions and fuel economy

Regular oil changes, air filter replacements, and spark plug service keep your 2014 Charger running efficiently and help it pass emissions testing. Synthetic oil can sometimes improve fuel economy slightly compared to conventional oil, though the difference is usually small. Your owner's manual specifies the recommended service intervals for your specific engine.

The catalytic converter is the primary emissions control component and typically lasts the life of the vehicle if the engine is running properly. If your check engine light comes on, having the diagnostic code read by a mechanic will tell you whether the issue is related to emissions, fuel economy, or another system. Ignoring a check engine light can eventually lead to emissions test failure.

Comparing the 2014 Charger to other sedans from that year

The 2014 Charger's fuel economy is typical for a full-size sedan with V6 and V8 options. The V6 model's 25 highway mpg is competitive with other large sedans, though smaller midsize sedans from 2014 often achieved 28 to 32 highway mpg. If fuel economy is your primary concern, a midsize sedan would have been a more efficient choice, but the Charger offers more interior space and power.

The V8 models prioritize performance over efficiency, which is reflected in their 14 to 15 city mpg ratings. This is typical for V8 sedans from 2014 and reflects the trade-off between engine size and fuel consumption that applies across the industry.

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. All models use gasoline engines only. If fuel efficiency was a priority for your purchase, the V6 model is the most economical option available for that year.

What should I do if my 2014 Charger fails an emissions test?

Take it to a certified mechanic who can read the diagnostic trouble codes from your vehicle's computer. Common causes of failure include a faulty oxygen sensor, a problem with the catalytic converter, or a loose gas cap. Once the issue is identified and repaired, you can retest the vehicle.

Can I improve fuel economy by switching to premium gasoline?

No, unless you own the SRT model with the 6.4-liter engine, and even then the improvement is minimal. The V6 and standard V8 are designed for regular unleaded fuel. Using premium will not improve mileage or performance in those engines and is an unnecessary expense.

How often does a 2014 Charger need emissions testing?

This depends on your state and local regulations. Some states require annual testing, others every two years, and some do not require it at all. Contact your state's environmental or motor vehicle agency to find out the testing schedule for your location and vehicle.

What is the fuel tank capacity of the 2014 Charger?

The 2014 Charger has an 18.5-gallon fuel tank across all engine options. With the V6 achieving an average of around 20 mpg combined, this gives you a driving range of approximately 370 miles per tank under typical conditions.
