How much horsepower does a 2017 5.7 Hemi have?
The 2017 5.7-liter Hemi is commonly rated at 395 horsepower (SAE net) in Ram 1500 pickups.
Beyond the Ram lineup, the same 5.7-liter Hemi V8 powers several other vehicles, including the Dodge Challenger and Charger in R/T trim and the Jeep Grand Cherokee. In these applications, published horsepower figures typically fall in the mid-to-high 300s, with torque around 410 lb-ft. Power output can vary by model year, exhaust setup, and drivetrain configuration, so the exact number on your specific vehicle may differ. The engine generally uses an 8-speed automatic transmission and may employ features like variable valve timing and cylinder deactivation to balance power and efficiency.

How horsepower is measured and what affects it
Horsepower is typically reported as SAE net horsepower at the crank, incorporating modern accessories and drivetrain losses. The 5.7 Hemi’s output benefits from features like variable valve timing and cylinder deactivation (where equipped) to improve efficiency without sacrificing low- and mid-range power. Real-world performance depends on many factors, including payload, drivetrain (2WD vs. 4WD), exhaust system, and transmission tuning.
Summary: In 2017, the 5.7 Hemi’s official, widely cited figure is 395 hp for Ram 1500 applications; other 5.7L Hemi-equipped models—Dodge Challenger/Charger and Jeep Grand Cherokee—typically reported numbers in the mid- to high-300s with torque around 410 lb-ft. Always verify the exact rating for your specific vehicle configuration.
