How much horsepower does a Dodge Magnum 5.7 V8 have?
Typically about 345 horsepower and around 370 lb-ft of torque.
The Dodge Magnum with a 5.7-liter Hemi V8 was produced in the mid-2000s and offered a robust V8 option in a family wagon. While horsepower can vary by year and configuration, the Magnum RT’s 5.7-liter engine is most commonly cited at these figures. This article outlines the core numbers and how to interpret them for common configurations.
Core performance figures
Below are the standard figures most buyers and enthusiasts cite for the 5.7-liter Hemi in the Magnum lineup. They reflect the engine’s peak power output and typical torque delivery in ordinary driving conditions.
- Horsepower: 345 hp (256 kW) at approximately 5,600 rpm
- Torque: 370 lb-ft (502 N·m) at around 4,200 rpm
Note: Some model years and emissions configurations used cylinder deactivation and tuning that could cause minor differences in peak numbers. The values above reflect the conventional ratings for the Magnum RT's 5.7 Hemi.
Year-to-year context and how to verify
During its run in the Dodge Magnum (roughly 2005–2008 for the 5.7-liter version), the engine delivered solid V8 performance. If you own a specific vehicle and need the exact figure, consult the vehicle’s window sticker, build sheet, or VIN decoder—ratings can vary by market, transmission choice, and whether the engine used features like MDS (cylinder deactivation) and other options.
Keep in mind that the 5.7 Hemi is often paired with a 5-speed automatic in the Magnum, which can influence real-world acceleration feel, even though peak horsepower remains as cited above.
How ratings are presented and why they differ
Horsepower numbers in factory specifications reflect peak output under standardized SAE testing. Real-world conditions—air intake, exhaust setup, altitude, and drivetrain losses—can cause slight deviations in measured horsepower, which is why sources can vary by a small margin.
Summary
The Dodge Magnum equipped with the 5.7-liter Hemi V8 typically outputs about 345 horsepower and around 370 lb-ft of torque. Exact figures can vary by year, trim, and emissions configuration, so checking the specific documentation for a given vehicle is the best way to confirm its precise rating.
