The Heart of the Beast: A Comprehensive Guide to Dodge Ram Engines

For years, the name “Ram” has actually been synonymous with power, resilience, and American engineering. Whether it was under the Dodge umbrella or as the standalone Ram Trucks brand, the powertrain has actually always been the centerpiece of the vehicle's identity. From the rumble of a HEMI V8 to the whistle of a Cummins Turbo Diesel, the engines discovered in Ram trucks are designed to manage everything from day-to-day commutes to the most requiring job websites.

This guide checks out the advancement, specifications, and efficiency of the most renowned engines found in the Dodge Ram lineup, supplying an in-depth appearance at what makes these pickups some of the most capable vehicles on the roadway.

1. The Legendary HEMI Powerhouse

The HEMI engine is possibly the most popular powertrain associated with the Ram brand. Taking its name from its hemispherical combustion chambers, this engine design enables for bigger valves and enhanced air flow, resulting in significant horse power gains.

The 5.7 L HEMI V8 with eTorque

The 5.7 L HEMI has been the “bread and butter” of the Ram 1500 for nearly two years. In current years, Ram introduced the eTorque mild-hybrid system. Instead of a standard generator, the engine uses a belt-driven motor generator system that provides smooth start/stop functions and includes a burst of torque for preliminary acceleration.

The 6.4 L HEMI V8 (Heavy Duty)

Found in the Ram 2500 and 3500 designs, the 6.4 L HEMI is constructed for those who require maximum gas-powered towing capability. It compromises some of the 5.7 L's fuel efficiency for pure, untainted pulling power and payload capability.

The Supercharged 6.2 L HEMI (TRX)

At the pinnacle of the V8 age sits the 6.2 L Supercharged HEMI, found in the Ram 1500 TRX. This engine turned the Ram into a desert-running supercar, producing 702 horsepower and making it the most powerful mass-produced gas-powered pickup worldwide during its production run.

2. The Cummins Turbo Diesel: The King of Torque

Considering that 1989, the collaboration between Ram and Cummins has actually defined the durable truck market. Unlike numerous competitors who used V8 diesel motor, Cummins stuck with an Inline-Six (I6) setup.

Why the Inline-Six?

The I6 style is inherently well balanced, suggesting it vibrates less than a V8. Furthermore, it has fewer moving parts and massive main bearings, which contributes to the legendary “500,000-mile” durability often related to these trucks.

Efficiency Specifications

The modern-day 6.7 L Cummins comes in 2 versions: the Standard Output (SO) and the High Output (HO). The High Output variation, available in the Ram 3500, was the very first in its class to break the four-digit torque barrier, using 1,075 lb-ft of torque.

3. The Modern Era: Pentastar and the Hurricane

As fuel guidelines tighten and technology progresses, Ram has actually moved its focus toward performance without compromising efficiency.

3.6 L Pentastar V6

The Pentastar is the entry-level engine for the Ram 1500. While it lacks the “theatrics” of the V8, it is an extremely dependable, award-winning engine that supplies enough power for light towing and excellent fuel economy for a full-sized truck.

The Hurricane Inline-6 (The Future)

For the 2025 design year and beyond, Ram is phasing out the V8 engines in favor of the “Hurricane” 3.0 L Twin-Turbo Inline-6. This engine is designed to supply V8 power— and even surpass it— while using the effectiveness of a smaller sized displacement engine. It represents the most significant shift in Ram engine philosophy in thirty years.
