How much HP does a 5.7 HEMI Magnum have?
The 5.7 HEMI Magnum’s horsepower varies by model year and configuration, but it typically starts around 345 horsepower in the earlier generations and recent, eTorque-equipped versions push up to about 395 horsepower.
Understanding the 5.7 HEMI Magnum
The 5.7 HEMI Magnum refers to a 5.7-liter V8 powerplant used across a range of Dodge and Chrysler vehicles. The “Magnum” branding has appeared on various Mopar engines, and the 5.7 HEMI was one of the first larger-displacement HEMI designs to be widely paired with modern technologies. Over its lifetime, output evolved through updates in intake, valve timing, and drivetrain systems, leading to higher peak horsepower on later models.
Horsepower by Era
The following figures capture the general, widely cited outputs across representative periods. Specific numbers can vary by market, model, and equipment, so consult the exact window sticker or manufacturer specifications for a given vehicle.
- Early 5.7 HEMI Magnum (roughly 2003–2008): about 345 horsepower and around 370 lb-ft of torque.
- Modern 5.7 HEMI with updates and eTorque (roughly 2019–present): about 395 horsepower and around 410 lb-ft of torque.
In practice, the on-road feel of the engine can differ based on gearing, drivetrain (RWD vs. AWD), and whether the vehicle uses technologies like displacement on demand or mild-hybrid assistance. When shopping, always verify the exact horsepower rating and torque figures for the specific model year and trim.
Notes for shoppers and enthusiasts
Horsepower ratings are often accompanied by torque figures and other performance metadata. Some trims or market versions may carry slight variations. If you’re evaluating a car or truck that uses the 5.7 HEMI Magnum, check the official spec sheet for the precise numbers tied to that configuration.
Why HP Matters for Drivers
Higher horsepower generally translates to quicker acceleration and stronger passing capability, especially when combined with heavier vehicles like trucks or performance sedans. However, fuel economy, weight, gear ratios, and torque delivery also play crucial roles in real-world performance.
Summary
Across its history, the 5.7 HEMI Magnum has delivered roughly 345 horsepower in its early iterations and about 395 horsepower in later, eTorque-equipped configurations. The exact figure depends on the model year, trim, and whether modern assist technologies are in use. For anyone evaluating a specific vehicle, the most reliable approach is to review the official spec sheet or the vehicle’s window sticker to confirm the exact horsepower for that build.

How much horsepower does a 5.7 Hemi Magnum have?
340 hp
The 5.7 L (345 cu in) Hemi in the Ram delivered 345 hp (257 kW) and 375 lb⋅ft (508 N⋅m), but 340 hp (254 kW) and 390 lb⋅ft (529 N⋅m) for the 300C and Magnum R/T, which is exactly 100 hp (75 kW) more than the old 5.9 engine.
Is the 5.7 Hemi Magnum a good engine?
The 5.7-liter Hemi is considered a reliable engine since it's reintroduction in the early 2000s. However, no engine on the market comes without its flaws. Ryan Wolfe: Another problem is prolonged idling periods.
