What is the best year for the 5.7 Hemi?
The "best" year for the 5.7L Hemi depends on priorities, but many consider 2014 to be a top choice because it was the last year with an unlocked PCM and was paired with the 8-speed transmission. Other popular years include the 2018-2020 models for their modern engineering and safety, and 2016-2017 for a balance of reliability and features. For the newest available technology and power, the 2024 and 2026 models with the eTorque system are strong contenders, though the 2026 model is the most recent to be announced.
Top picks by category
- 2014 For tuning enthusiasts: is often cited as the best year because it was the last model year before the PCM was locked down, allowing for easier aftermarket tuning.
- For modern features and reliability: The 2018-2020 Ram 1500s are well-regarded for their refined engineering, enhanced safety, and upgraded interiors.
- 2016 and 2017 For a balance of features and reliability: are considered excellent years, offering a combination of the reliable Hemi engine and fewer issues than some predecessors.
- 2024 and 2026 For the newest technology: models offer the most up-to-date features, including the eTorque mild-hybrid system and 8-speed transmission.
Other considerations
- Pre-2009 models: The 5.7L Hemi was revised starting in 2009 with improvements like variable valve timing (VVT) and the Multi-Displacement System (MDS). While older engines are durable, the newer versions offer better efficiency and have addressed some common issues found in the first generation, according to Heavy Duty Parts Company.
- Maintenance is key: Regardless of the year, the overall reliability and longevity of any 5.7L Hemi are heavily dependent on consistent and proper maintenance.
Is the 5.7 an actual hemi?
The first of the "third generation" Hemis was the 5.7-liter, gas-powered, 90-degree, pushrod V8 that replaced the older 5.9-liter Magnum V8 in 2003 Dodge Ram pickups. This new hemi was a clean sheet design with a cast iron block, four-bolt main bearings, forged con rods, and lightweight aluminum pistons.
Why is a 5.7 called a hemi?
The name HEMI comes from the hemispherical (meaning half circle) piston heads used in the eponymous engines. The rounded piston heads, slotted into a rounded chamber to match, offered higher efficiency with less energy lost to heat while fuel is combusted before being sent out as exhaust.
