Engine and Powertrain Details

The 2007 Dodge Charger SRT8 uses a 6.1-liter V8 engine that produces 425 horsepower and 420 pound-feet of torque. This engine is paired with a 5-speed automatic transmission and rear-wheel drive. The SRT8 badge indicates this is Dodge's high-performance variant, engineered by the Dodge Special Vehicle Team.

The engine itself is based on the Chrysler 6.1L Hemi V8, which was designed for durability and power output. The SRT8 version includes performance tuning, a sport-tuned suspension, and upgraded braking components compared to the standard Charger models available that year.

Key Takeaways

  • The 2007 Charger SRT8 produces 425 horsepower from a 6.1-liter V8 engine paired with a 5-speed automatic transmission.
  • EPA fuel economy ratings are 16 miles per gallon in city driving and 25 miles per gallon on highways when operating on regular unleaded gasoline.
  • The vehicle weighs approximately 4,360 pounds and has a curb weight that affects its emissions classification and fuel consumption.
  • This model year meets EPA Tier 2 emissions standards and is classified as a full-size sedan in the heavy-duty vehicle category.
  • The SRT8 requires premium fuel for optimal performance, though regular unleaded gasoline is acceptable for normal driving conditions.

Fuel Economy and Emissions Standards

The 2007 Charger SRT8 is rated at 16 miles per gallon in city driving and 25 miles per gallon on highways, with a combined rating of 19 miles per gallon. These figures assume normal driving conditions and regular maintenance. Actual fuel consumption varies based on driving habits, road conditions, and vehicle load.

The vehicle meets EPA Tier 2 emissions standards, which were the federal requirement for 2007 model year vehicles. It produces emissions of nitrogen oxides and particulate matter within the limits set for that classification. The SRT8 is classified as a full-size sedan in the heavy-duty vehicle category for emissions purposes.

Transmission and Drivetrain Specifications

The 5-speed automatic transmission in the 2007 SRT8 was designed to handle the engine's high torque output while maintaining reasonable fuel economy. The transmission features a torque converter and is tuned for performance driving, with shift points optimized for the V8 engine's power band.

Rear-wheel drive is standard on all 2007 Charger models, including the SRT8. The vehicle uses a solid rear axle with a limited-slip differential, which helps distribute power evenly to both rear wheels during acceleration and cornering.

Weight and Dimensions

The 2007 Dodge Charger SRT8 has a curb weight of approximately 4,360 pounds, making it one of the heavier sedans of that generation. The vehicle measures 200.3 inches in overall length, 75.7 inches in width, and 59.8 inches in height. These dimensions place it in the full-size sedan category.

The weight distribution and size affect how the vehicle handles emissions testing, fuel economy calculations, and safety ratings. The SRT8's weight is partly due to its reinforced suspension components and performance-oriented frame structure.

Fuel Type and Octane Requirements

Dodge recommends premium unleaded gasoline with an octane rating of 91 or higher for the 2007 Charger SRT8. Premium fuel allows the engine to operate at its rated horsepower and torque specifications. The engine uses a knock sensor that adjusts ignition timing if lower-octane fuel is detected.

Regular unleaded gasoline with an octane rating of 87 can be used in the SRT8, though the engine will reduce power output slightly to prevent detonation. Long-term use of regular fuel may affect engine performance and fuel economy compared to the specifications listed above.

Performance Capabilities and Acceleration

The 2007 Charger SRT8 accelerates from 0 to 60 miles per hour in approximately 4.2 seconds, with a quarter-mile time near 12.7 seconds. Top speed is electronically limited to 175 miles per hour. These figures are based on standard testing conditions with a professional driver and optimal road surface.

The performance numbers reflect the engine's 425 horsepower output and the transmission's ability to deliver that power to the rear wheels efficiently. Real-world acceleration times vary based on road conditions, tire grip, and driver technique.

Maintenance and Operational Considerations

The 2007 Charger SRT8 requires regular oil changes every 3,000 to 5,000 miles, depending on driving conditions. The engine uses 5.5 quarts of SAE 5W-30 motor oil. Spark plugs should be inspected at 30,000 miles and replaced as needed, as the SRT8 uses long-life spark plugs designed for extended intervals.

The vehicle's performance suspension and high-output engine mean that brake fluid, transmission fluid, and coolant should be checked regularly. The SRT8 uses a larger cooling system than standard Chargers to handle the additional heat generated by the powerful V8 engine.

Frequently Asked Questions

What is the difference between the 2007 Charger SRT8 and the standard Charger?

The SRT8 has a 6.1-liter V8 engine with 425 horsepower, while standard Chargers used smaller V8 or V6 engines with less power. The SRT8 also includes a sport-tuned suspension, upgraded brakes, and performance-oriented interior and exterior styling. Fuel economy is lower on the SRT8 due to the larger engine.

Can the 2007 Charger SRT8 run on regular gasoline?

Yes, regular unleaded gasoline with 87 octane can be used, but the engine will reduce power output to prevent detonation. Dodge recommends premium fuel with 91 octane or higher for full performance. Using regular fuel occasionally will not damage the engine, but long-term use may reduce horsepower and fuel economy.

What is the towing capacity of the 2007 Charger SRT8?

The 2007 Charger SRT8 is not rated for towing. The vehicle is a performance sedan designed for speed and handling, not for towing trailers or heavy loads. Attempting to tow with this vehicle could damage the transmission and drivetrain.

How much does it cost to fill the 2007 Charger SRT8 fuel tank?

The fuel tank capacity is 18.0 gallons. The cost to fill depends on current fuel prices in your area. At average 2024 prices, filling a completely empty tank with premium gasoline would cost between $60 and $75, though this varies by location and fuel grade.

What safety features does the 2007 Charger SRT8 include?

The 2007 SRT8 includes dual front airbags, side-impact airbags, and curtain airbags. It has anti-lock brakes, electronic stability control, and traction control as standard equipment. The vehicle also includes a tire pressure monitoring system and daytime running lights.
