The Dodge Charger lineup spans five distinct generations, each with different engine options, fuel economy, and emissions profiles

The Dodge Charger has been produced in five separate generations since 1966, with long gaps between some of them. The first generation ran from 1966 to 1974. The second generation appeared from 1975 to 1978. After a 24-year break, Dodge brought back the Charger name in 2006 for a modern sedan that continued through 2024. Each generation had different powertrains, which affects how they perform environmentally and what fuel costs look like over time.

If you are researching Dodge Chargers for purchase or ownership, understanding which generation you are looking at matters because the engines, transmissions, and fuel efficiency vary widely. A 1970 Charger and a 2020 Charger are fundamentally different vehicles in terms of emissions and running costs, even though they share a name.

Key Takeaways

  • The Dodge Charger has five generations: 1966–1974, 1975–1978, and 2006–2024, with significant gaps between them.
  • First and second generation Chargers used large V8 engines with poor fuel economy and higher emissions than modern vehicles.
  • The modern Charger (2006–2024) offered multiple engine choices ranging from a V6 to a supercharged V8, with fuel economy improving in later model years.
  • Emissions standards tightened significantly after 1975, so newer Chargers produce far fewer pollutants than older ones.
  • Fuel economy for modern Chargers ranges from roughly 16 to 25 miles per gallon depending on engine choice and driving conditions.

First Generation Charger (1966–1974)

The original Dodge Charger was a muscle car built on a mid-size platform. It came standard with a 318-cubic-inch V8 engine producing 230 horsepower, though buyers could order larger V8s including a 440 and a 426 Hemi. The bigger engines produced 375 to 425 horsepower depending on the year and configuration.

Fuel economy for first-generation Chargers was poor by any standard. The 318 V8 averaged around 10 to 12 miles per gallon in city driving. The larger engines performed worse, often dropping to 8 to 10 miles per gallon. These vehicles had no emissions control systems by modern standards — catalytic converters did not become standard until the mid-1970s — so they produced significantly higher levels of nitrogen oxides and particulate matter than any vehicle sold today.

Second Generation Charger (1975–1978)

Dodge redesigned the Charger for 1975 as a mid-size sedan on a different platform. The standard engine was a 318 V8 with 150 horsepower, a substantial drop from the muscle car era. A 400 V8 and a 440 V8 were also available, producing 185 and 208 horsepower respectively. A 225-cubic-inch slant-six engine was offered as the base option, producing 95 horsepower.

Fuel economy improved slightly over the first generation but remained poor. The slant-six achieved roughly 13 to 15 miles per gallon, while the 318 V8 managed 10 to 12 miles per gallon. The larger V8s fell below 10 miles per gallon in most driving conditions. By this time, catalytic converters were required, which reduced emissions substantially compared to the 1960s models, though they were still far higher than modern standards.

Modern Charger: First Years (2006–2010)

Dodge revived the Charger name in 2006 as a full-size four-door sedan. The base engine was a 2.7-liter V6 producing 178 horsepower and achieving approximately 17 to 19 miles per gallon combined. A 3.5-liter V8 was available, producing 250 horsepower with fuel economy around 15 to 17 miles per gallon. The high-performance R/T model used a 5.7-liter V8 with 370 horsepower and fuel economy of roughly 14 to 16 miles per gallon.

These vehicles met the emissions standards in place at the time, which required catalytic converters, oxygen sensors, and computer-controlled fuel injection. Compared to 1970s Chargers, emissions of nitrogen oxides and hydrocarbons were reduced by roughly 90 percent or more, though the standards have tightened further since then.

Modern Charger: Mid-Generation Update (2011–2014)

Dodge updated the Charger for 2011 with a new front end and interior. Engine choices remained similar: the 2.7-liter V6, the 3.6-liter V8, and the 5.7-liter V8. The 3.6-liter V8 became more common as the mid-range option, producing 292 horsepower with fuel economy around 16 to 18 miles per gallon combined. The 5.7-liter V8 in the R/T continued to deliver roughly 14 to 16 miles per gallon.

Emissions control systems became more sophisticated during this period, with improved catalytic converters and particulate filters. Real-world emissions of pollutants like nitrogen oxides continued to decline compared to earlier model years, though testing procedures did not change significantly until 2017.

Modern Charger: Final Generation (2015–2024)

The 2015 redesign brought a new platform and updated engines across the lineup. The base V8 was a 3.6-liter producing 292 horsepower with fuel economy of approximately 16 to 19 miles per gallon combined. The R/T used a 5.7-liter V8 with 370 horsepower and roughly 15 to 17 miles per gallon. The SRT Hellcat, introduced in 2015, featured a supercharged 6.2-liter V8 producing 707 horsepower but achieving only 12 to 14 miles per gallon.

In 2016, Dodge added a 5.7-liter V8 with cylinder deactivation technology, which improved fuel economy to around 16 to 18 miles per gallon by shutting off half the cylinders during light-load driving. The 2019 model year brought further refinements to emissions systems, including updated oxygen sensors and catalytic converters designed to meet stricter standards that took effect that year. The Hellcat Redeye, introduced in 2019, maintained similar fuel economy to the standard Hellcat despite increased horsepower.

Comparing Fuel Economy Across Generations

The jump in fuel economy from the 1970s to the 2000s is dramatic. A 1975 Charger with a 318 V8 might cost $3,000 to $4,000 per year in fuel at current prices, assuming 12,000 miles of driving annually and average gas prices. A 2015 Charger with the same engine size would cost roughly $1,200 to $1,500 per year in fuel under the same conditions. Even the high-performance Hellcat, which consumes fuel at a rate similar to 1970s muscle cars, meets modern emissions standards that the older vehicles cannot.

If you are considering an older Charger for historical or collector purposes, factor in higher fuel costs and the reality that these vehicles cannot meet current emissions standards in most states. Modern Chargers, while still thirsty compared to sedans with smaller engines, represent a massive improvement in both efficiency and environmental impact.

Frequently Asked Questions

What engine did the original 1966 Charger have?

The 1966 Charger came standard with a 318-cubic-inch V8 producing 230 horsepower. Buyers could order a 440 or 426 Hemi V8 for higher performance. The 426 Hemi produced 425 horsepower in 1966 and was one of the most powerful engines available that year.

Can I register a 1970s Dodge Charger in a state with strict emissions rules?

Most states with strict emissions testing will not allow vehicles older than 25 to 30 years to be tested, or they exempt them entirely. However, some states require older vehicles to meet the standards that were in place when they were built, not current standards. Check your state's emissions rules before purchasing an older Charger.

Which modern Charger engine gets the best fuel economy?

The 3.6-liter V8 in the 2015–2024 Charger achieves the best fuel economy among V8 options, with real-world combined fuel economy around 17 to 19 miles per gallon. The 2.7-liter V6 in earlier models (2006–2010) was slightly more efficient but produced less power.

How much more pollution does a 1970 Charger produce compared to a 2020 Charger?

A 1970 Charger without emissions controls produces roughly 10 to 15 times more nitrogen oxides and hydrocarbons than a 2020 Charger. The difference is even larger for particulate matter. Modern catalytic converters and computer-controlled fuel systems have reduced emissions dramatically, though the exact difference depends on the specific engines being compared.

Did Dodge make a Charger between 1979 and 2005?

No. Dodge discontinued the Charger after 1978 and did not produce another vehicle with that name until 2006. The 24-year gap reflects changing market demand and Dodge's focus on other models during that period.
