The Dodge Charger SRT8 is a high-performance sedan built between 2006 and 2014

The Dodge Charger SRT8 is a four-door muscle car that Dodge manufactured from 2006 through 2014. SRT8 stands for Street and Racing Technology 8-cylinder, referring to the 6.1-liter V8 engine that powered the first generation (2006–2010) and the 6.4-liter V8 in the second generation (2011–2014). These were the most powerful versions of the Charger lineup during their production years.

The SRT8 was designed to deliver straight-line acceleration and handling performance in a full-size sedan body. It came standard with a manual or automatic transmission, rear-wheel drive, and a performance-tuned suspension. The car weighed between 4,300 and 4,500 pounds depending on the model year and transmission choice.

Key Takeaways

  • The SRT8 Charger came in two generations: 2006–2010 with a 6.1L V8, and 2011–2014 with a 6.4L V8 producing more horsepower and torque.
  • Fuel economy for the SRT8 ranges from 14 to 16 miles per gallon in city driving and 23 to 25 mpg on the highway, depending on transmission type and model year.
  • The 2006–2010 models produce approximately 425 horsepower, while 2011–2014 models produce around 470 horsepower.
  • Emissions standards for the SRT8 meet EPA Tier 2 Bin 8 or Bin 9 requirements, which are stricter than many vehicles in its class.

Engine specifications and performance output

The first-generation SRT8 (2006–2010) uses a 6.1-liter naturally aspirated V8 engine that produces 425 horsepower at 6,200 rpm and 420 pound-feet of torque at 4,800 rpm. This engine is paired with either a five-speed automatic transmission or a six-speed manual transmission. The automatic version accelerates from 0 to 60 mph in approximately 4.5 seconds, while the manual transmission version achieves the same in roughly 4.7 seconds.

The second-generation SRT8 (2011–2014) upgraded to a 6.4-liter V8 that generates 470 horsepower at 6,000 rpm and 470 pound-feet of torque at 4,300 rpm. This generation also offered a five-speed automatic or six-speed manual. The 2011–2014 models are faster, reaching 60 mph in approximately 4.2 seconds with the automatic transmission.

Fuel consumption and emissions ratings

The SRT8 Charger is not a fuel-efficient vehicle, which is typical for large-displacement V8 engines. The 2006–2010 models with the automatic transmission achieve approximately 14 mpg in city driving and 23 mpg on the highway. Manual transmission versions perform slightly better on the highway at 24 to 25 mpg but similar in city driving. The 2011–2014 models with the larger 6.4L engine show similar or slightly lower efficiency, with ratings around 14 mpg city and 23 mpg highway for automatic models.

All SRT8 Chargers require premium unleaded gasoline (91 octane or higher) to operate correctly and achieve rated performance. Using regular gasoline can cause engine knock and reduce power output. The fuel tank capacity is 18.5 gallons, which means highway range is typically 400 to 450 miles per tank.

EPA emissions classification

The SRT8 Charger meets EPA Tier 2 Bin 8 or Bin 9 emissions standards, depending on the model year and transmission. These classifications place the vehicle in a stricter category than many other large sedans and trucks, though not as strict as hybrid or smaller-engine vehicles. Tier 2 Bin 8 and Bin 9 vehicles produce between 0.125 and 0.156 grams of nitrogen oxides per mile, which is significantly lower than older muscle cars but higher than modern fuel-efficient sedans.

The SRT8 also includes a catalytic converter and particulate filter to reduce harmful emissions. Some states with stricter air quality standards may have additional restrictions on older SRT8 models, particularly those from 2006–2008. If you live in California or another state that follows California emissions standards, check your local regulations before purchasing a used SRT8.

Maintenance and long-term ownership costs

Owning an SRT8 Charger involves higher maintenance expenses than a standard sedan. Oil changes require synthetic oil and cost between $80 and $150 per service. Brake pads wear faster due to the vehicle's weight and performance use, and replacement typically costs $400 to $800 per axle. Tire replacement is expensive because the SRT8 uses performance tires sized 245/45R20 or larger, which cost $200 to $300 per tire.

Engine repairs are costly if problems develop. The 6.1L and 6.4L V8 engines are generally reliable, but spark plug replacement, timing chain service, and transmission work can run $1,500 to $4,000 depending on the issue. Insurance premiums for the SRT8 are typically 20 to 40 percent higher than a standard Charger due to the high performance classification and repair costs.

Common issues and reliability concerns

The 2006–2010 SRT8 models occasionally experience transmission issues with the five-speed automatic, particularly if the vehicle was driven aggressively or not properly maintained. Some owners report rough shifting or delayed engagement. The six-speed manual is generally more reliable but requires more driver engagement.

Cooling system problems can occur in both generations, especially in hot climates. The radiator and water pump may need replacement between 80,000 and 120,000 miles. Suspension components, including control arms and bushings, wear faster on the SRT8 than on standard Chargers due to the stiffer suspension tuning and increased weight transfer during cornering.

Frequently Asked Questions

Is the SRT8 Charger street legal?

Yes, the SRT8 Charger is a street-legal production vehicle sold through Dodge dealerships. It meets all federal safety and emissions standards. However, some states restrict vehicles with high emissions ratings or require additional testing for older models, so check your local regulations.

Can I modify the SRT8 for more power?

Yes, many aftermarket upgrades are available, including cold air intakes, exhaust systems, and engine tuning. However, modifications may affect emissions compliance and void your warranty. Some modifications require re-certification in states with strict emissions rules.

What is the difference between SRT8 and R/T Charger?

The R/T Charger uses a 5.7-liter V8 with 370 horsepower, while the SRT8 uses a larger 6.1L or 6.4L V8 with 425 or 470 horsepower. The SRT8 also includes upgraded suspension, brakes, and interior features. The SRT8 is faster and more expensive.

How much does an SRT8 Charger cost used?

Used SRT8 prices vary widely based on mileage, condition, and model year. A 2006–2010 model typically ranges from $12,000 to $20,000, while 2011–2014 models range from $18,000 to $28,000. Prices depend on local market conditions and individual vehicle history.

Is the SRT8 good for daily driving?

The SRT8 is a four-door sedan with a back seat and trunk, so it can serve as a daily driver. However, poor fuel economy, firm suspension tuning, and high maintenance costs make it less practical than a standard Charger for commuting. It is better suited for weekend driving or performance enthusiasts.
