The 5.7-liter Hemi V8 in the Chrysler 300 is typically rated at about 345 horsepower, with some later calibrations reaching roughly 372 horsepower depending on year and equipment.
Baseline figures and what they mean
Understanding the 5.7L Hemi’s horsepower helps explain a Chrysler 300’s performance, but numbers can vary by year and configuration. Below is a concise look at the key figures you’re likely to encounter.
Typical horsepower and torque figures you’ll encounter for the 5.7L Hemi in the 300:
- Horsepower: 345 hp (approximately 257 kW)
- Torque: around 375 lb-ft (508 Nm)
- Redline: roughly 6,000 rpm
- Common transmission pairings: historically a 5-speed automatic in earlier years, with updates in later years offering more modern automatics
Exact rating can vary by year, emissions configuration, and driveline updates. For the precise figure on a specific car, check the window sticker or VIN-referenced documentation.
Year-to-year considerations and updated figures
Engine calibrations and emissions technology can nudge the published horsepower up or down. For the 5.7L Hemi in the Chrysler 300, many early model years list 345 hp, while certain later calibrations have been reported around 372 hp. If you’re evaluating a used car or restoring data for a particular VIN, the exact number is best confirmed on the factory window sticker or via the manufacturer’s VIN lookup.
- 345 hp is the baseline figure seen on many early-to-mid-2000s 5.7L Hemi 300s
- Some later calibrations list about 372 hp, reflecting engine updates or different emissions setups
For context, the Chrysler 300’s higher-performance variant, the SRT8, uses a different engine—the 6.1-liter Hemi—rated at around 425 horsepower, which is substantially more than the standard 5.7L package.
Summary
In summary, the standard 5.7L V8 in the Chrysler 300 typically delivers about 345 horsepower, with certain later calibrations reaching around 372 horsepower depending on the model year and configuration. Always verify the exact figure for your vehicle via the window sticker or VIN lookup. The 5.7L sits below the SRT8’s 425 hp, which uses a different engine entirely.
