What the 2010 Charger delivers in real-world fuel use and tailpipe output

The 2010 Dodge Charger came in three engine options, and fuel economy varied significantly between them. The base 3.5-liter V8 achieved 16 miles per gallon city and 25 highway. The mid-range 5.7-liter V8 (Hemi) dropped to 15 city and 23 highway. The high-performance 6.1-liter SRT8 model managed 14 city and 22 highway. These figures assume regular unleaded fuel and automatic transmission, which all 2010 Chargers used.

The 2010 Charger met EPA Tier 2 Bin 5 emissions standards for that model year, meaning it produced nitrogen oxides and particulate matter within federal limits. It was not a low-emissions vehicle by modern standards, but it complied with the rules in effect when it was built. The vehicle's combined rating placed it in the middle range for full-size sedans of that era—better than some muscle cars, worse than economy sedans.

Key Takeaways

  • The 2010 Charger's fuel economy ranged from 14–16 mpg city and 22–25 mpg highway depending on which of the three V8 engines you owned.
  • All three engines required regular unleaded gasoline; premium fuel was not necessary for any 2010 Charger model.
  • The vehicle met EPA Tier 2 emissions standards but did not carry a low-emissions or hybrid designation.
  • Real-world fuel consumption often ran 1–2 mpg lower than EPA estimates, especially in city driving or with aggressive acceleration.

Engine options and their fuel consumption differences

The base 3.5-liter V8 was the most efficient of the three, though "efficient" is relative for a full-size V8 sedan. It produced 250 horsepower and was standard on the SE and SXT trims. Drivers reported that steady highway driving at 55–65 mph could yield closer to 26–27 mpg, while city driving rarely exceeded 15 mpg.

The 5.7-liter Hemi V8 was the most common choice and came standard on R/T models. It made 370 horsepower and had a variable valve timing system that helped it achieve slightly better efficiency than older Hemi engines. In practice, owners reported 14–16 mpg in mixed driving, with highway figures around 23–24 mpg when not driven aggressively.

The 6.1-liter SRT8 engine was the thirstiest option, producing 425 horsepower. It was built for performance, not economy. Owners of this model typically saw 13–15 mpg in real-world driving. The SRT8 also required premium fuel (91 octane or higher), unlike the other two engines.

How the 2010 Charger compares to other sedans from that year

In 2010, the Charger's fuel economy was typical for a full-size V8 sedan but notably worse than mid-size sedans with four-cylinder or V6 engines. A 2010 Toyota Camry with a V6 achieved 19 city and 28 highway. A 2010 Honda Accord V6 managed 18 city and 27 highway. The Charger's advantage was power and interior space; its disadvantage was fuel cost.

Compared to other performance sedans, the Charger held its own. The 2010 Chrysler 300C, which shared the same platform and engines, had identical fuel economy ratings. The 2010 Pontiac G8 GT (5.7-liter V8) achieved 15 city and 24 highway—marginally better. The 2010 Chevrolet Impala SS (6.0-liter V8) managed 14 city and 21 highway—slightly worse.

Emissions standards the 2010 Charger met

The 2010 Charger was certified to EPA Tier 2 Bin 5 standards, which set limits on nitrogen oxides (NOx) and non-methane organic gas (NMOG) emissions. These standards were federal requirements for all light-duty vehicles sold in the United States that year. The Charger did not carry a special low-emissions vehicle (LEV) badge or hybrid designation because it did not exceed those baseline requirements.

In states with California emissions standards—California, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington—the 2010 Charger had to meet California's Tier 2 standards, which were slightly stricter. The vehicle was certified for sale in those states, meaning it met both sets of rules.

What affects real-world fuel economy in a 2010 Charger

EPA estimates assume a mix of city and highway driving at moderate speeds with a properly maintained vehicle. Real-world results depend heavily on driving habits. Aggressive acceleration, frequent braking, and city driving with many stops can reduce fuel economy by 2–4 mpg compared to EPA figures. Conversely, steady highway driving at 55 mph can improve it by 1–2 mpg.

Maintenance also matters. A 2010 Charger with a clogged air filter, worn spark plugs, or low tire pressure will consume more fuel than one that is well-maintained. Tire pressure has the largest effect—underinflated tires can reduce fuel economy by up to 3 percent per 1 psi below the recommended pressure. The recommended tire pressure for 2010 Chargers is listed on a sticker inside the driver's door jamb, not on the tire sidewall.

Payload and driving conditions matter too. Carrying extra weight, towing, or driving in cold weather (which increases engine friction) all reduce fuel economy. A 2010 Charger is not designed for towing, but additional passengers and cargo will noticeably affect consumption.

Fuel type and octane requirements by engine

The 3.5-liter and 5.7-liter engines in the 2010 Charger were designed to run on regular unleaded gasoline (87 octane). Using premium fuel (91 or 93 octane) would not improve performance or economy in these engines and would straightforward cost more at the pump. The owner's manual explicitly states that regular fuel is acceptable.

The 6.1-liter SRT8 engine required premium fuel. Using regular fuel in this engine could cause engine knock (a pinging sound under acceleration), which can damage the engine over time. The SRT8 was tuned for higher compression and relied on premium fuel's higher octane rating to prevent knock. Owners of SRT8 models should never use regular fuel, even in a pinch.

Frequently Asked Questions

Can I improve fuel economy on my 2010 Charger?

Yes, within limits. Keep your tires properly inflated, maintain regular oil changes, replace air filters on schedule, and avoid aggressive acceleration. Steady highway driving at moderate speeds will always yield better economy than city driving. Expect 1–3 mpg improvement from good maintenance, not more.

What does "Tier 2 Bin 5" mean for emissions?

It means the vehicle meets federal emissions standards set by the EPA for that model year. Tier 2 Bin 5 is a baseline standard, not a special low-emissions rating. The vehicle produces nitrogen oxides and particulate matter within legal limits but is not cleaner than vehicles with LEV or CARB certifications.

Is the 2010 Charger a good choice if I drive a lot?

Not if fuel cost is a concern. At 15–16 mpg combined, a 2010 Charger will cost significantly more to fuel than a mid-size sedan or compact car. If you drive 15,000 miles per year at $3 per gallon, expect roughly $2,800–$3,000 annually in fuel costs, compared to $1,500–$1,800 for a more efficient sedan.

Does the 2010 Charger have a hybrid option?

No. Dodge did not offer a hybrid version of the 2010 Charger. All models came with conventional gasoline V8 engines. If fuel economy is a priority, a hybrid sedan from another manufacturer would be a better choice.
