Most Dodge Chargers with a 5.7 L Hemi V8 deliver about 370 horsepower in newer generations, while earlier models were around 345 horsepower. Exact figures vary by year, trim, and market.
Year-by-year snapshot
The horsepower of the 5.7 L Hemi in the Charger has shifted slightly over the years due to calibrations, emissions rules, and model updates. Below is a rough guide by era to illustrate how the rating has evolved.
- 2005–2008: approximately 345 horsepower
- 2009–2010: approximately 372 horsepower
- 2011–2014: approximately 370 horsepower
- 2015–2023: approximately 370 horsepower
Note: For a precise figure, check the vehicle’s window sticker or build sheet, since ratings can differ by market, options, and year.
Factors that influence horsepower ratings
Horsepower ratings are not a fixed number across every Charger with a 5.7 L Hemi. Several elements can affect the official horsepower printed on a spec sheet or sticker.
- Transmission type and drivetrain configuration (automatic vs manual, rear-wheel drive vs all-wheel drive)
- Engine calibration and emissions equipment (such as MDS and variable valve timing)
- Intake and exhaust modifications or aftermarket components
- Fuel quality, octane, and operating altitude
- Model-year-specific tuning and market-specific specifications
In practice, the official horsepower figures come from factory specifications, while actual wheel horsepower can vary slightly due to drivetrain losses and wear.
How to verify your exact horsepower
To determine your Charger’s exact 5.7 L Hemi horsepower for your specific vehicle, use these steps:
- Consult the window sticker (Monroney) on the driver’s door jamb for the stated horsepower
- Review the VIN/build sheet or the official Dodge/Mopar spec documents for your exact configuration
- Contact a Dodge dealer or reference the manufacturer’s online spec database using the VIN
If you want a real-world measurement, a chassis dynamometer can assess wheel horsepower, which is typically a bit lower than the engine’s crank horsepower due to drivetrain losses.
Summary
In summary, the 5.7 L Hemi-powered Charger typically sits around 370 horsepower in recent years, with earlier models closer to 345 horsepower. Exact numbers depend on model year, trim, and market, so always verify with the official build data for your vehicle.
