Powering the American Road A Comprehensive Guide to Dodge Ram Engines For decades the name Ram has actually been synonymous with rugged ability American engineering and most importantly famous powertrain alternatives While the brand name officially separated from Dodge in 2009 to become its own entity Ram Trucks many enthusiasts and owners in the USA still affectionately describe these cars as Dodge Rams Despite the nomenclature the heart of any Ram truck is its engine
From the fuelefficient Pentastar V6 to the earthshaking Cummins Turbo Diesel the evolution of Dodge Ram engines shows the altering landscape of the American vehicle industry This guide offers an indepth analysis of the existing and famous engines powering Ram trucks today their performance specs and the future of internal combustion in the pickup sector
1 The EntryLevel Workhorse 36 L Pentastar V6 with eTorque The 36 L Pentastar V6 has established itself as one of the most flexible and widely used engines in the Stellantis previously Chrysler portfolio In the Ram 1500 it acts as the base engine but base does not imply standard
Developed for chauffeurs who prioritize fuel economy without sacrificing the utility of a fullsize pickup the Pentastar features a dual overhead webcam DOHC style and variable valve timing VVT The modern iteration is coupled with the eTorque mildhybrid system This system replaces the conventional alternator with a beltdriven motor generator system which offers seamless startstop performance and adds a burst of torque during preliminary velocity
Best For Daily commuting lightduty transporting and fuelconscious fleet operations 2 Completion of an Era The 57 L HEMI V8 For almost 20 years the 57 L HEMI V8 was the gold requirement for the Ram 1500 Understood for its unique HEMI roar and hemispherical combustion chambers this engine provided the essential V8 experience
Like the Pentastar later on variations of the 57 L HEMI used the eTorque system to improve efficiency However as worldwide emissions standards tighten up Ram has actually announced the retirement of the 57 L HEMI in the 1500 lineup beginning with the 2025 design year In spite of its discontinuation in new lightduty trucks it remains a dominant force in the previously owned market and a preferred for those who value mechanical simplicity and tested longevity
3 The New Vanguard The 30 L Hurricane I6 The biggest news on the planet of Dodge Ram engines is the introduction of the 30 L Hurricane TwinTurbo Inline6 This engine represents a paradigm shift moving far from highdisplacement naturally aspirated V8s towards smallerdisplacement forcedinduction precision
The Hurricane engine can be found in two distinct outputs
Standard Output SO Optimized for a balance of fuel economy and power High Output HO Engineered for optimal performance going beyond the output of the outbound V8s The Hurricane engine uses 2 lowinertia turbochargers plasma transfer wire arc PTWA finishing in the cylinder tires for lowered friction and highpressure direct injection

The 64 L HEMI V8 Gas The 64 L HEMI is the standard engine for the Ram HD lineup Unlike the 57 L this engine is tuned for lowend torque and sturdiness under consistent load It includes MultiDisplacement System MDS technology which deactivates 4 cylinders throughout cruising to assist handle fuel consumption
The 67 L Cummins Turbo Diesel The Cummins name is famous in the USA Available in 2 versions Standard and High Output the 67 L inlinesix diesel motor supplies the enormous torque figures required to tow over 37000 pounds in properly equipped 3500 designs
Secret Features of the Cummins Diesel

Oil Change Intervals Modern Ram trucks feature an Oil Life Monitoring System It is recommended to change the oil every 7500 to 10000 miles or quicker if the truck is utilized for heavy towing Stimulate Plug Replacement The 57 L HEMI utilizes 16 trigger plugs 2 per cylinder These should normally be replaced every 100000 miles to prevent misfires Diesel Exhaust Fluid DEF For Cummins diesel owners keeping the DEF tank filled is mandatory to satisfy emissions standards and prevent limp mode Cooling System Care Turbocharged engines like the new Hurricane I6 produce substantial heat Routine evaluations of the coolant levels and hoses are vital to avoid turbo failure Air Filter Maintenance Trucks operated in dirty or offroad environments such as the Ram Rebel or TRX require more frequent air filter changes to safeguard the consumption system 6 The Future Electrification and the RAM REV The USA truck market is currently in a state of shift Ram has presented the Ram 1500 REV an allelectric version of the pickup Furthermore the Ramcharger model introduces a distinct principle an electric vehicle with an onboard gaspowered generator the 36 L Pentastar that acts solely as a variety extender never driving the wheels directly This hybrid technique aims to get rid of variety stress and anxiety while keeping the pulling abilities of a standard internal combustion engine
Regularly Asked Questions FAQ Is the 57 L HEMI being stopped Yes for the Ram 1500 lineup the 57 L HEMI V8 is being phased out in favor of the 30 L Hurricane TwinTurbo Inline6 However it stays offered in some Heavy Duty and older stock designs
Which Ram engine is the most reliable The 67 L Cummins Turbo Diesel is widely considered one of the most reliable engines in the world often reaching 300000 to 500000 miles with appropriate upkeep For learn more the 36 L Pentastar is kept in mind for its durability and low repair expenses
What is the distinction in between the Hurricane SO and HO The Standard Output SO is tuned for a balance of efficiency and power ideal for most drivers The High Output HO variation features various internal parts and greater boost levels developed for those who desire performance similar to or surpassing a standard V8
Does the Ram 1500 require premium fuel The 36 L Pentastar and 57 L HEMI can run on 89octane midgrade or 87octane regular though 89 is advised for the HEMI The brandnew 30 L Hurricane High Output engine needs premium fuel 91 octane or higher to attain its rated performance
Can the 36 L Pentastar tow a large trailer While the Pentastar is a capable engine its towing capacity is capped around 7700 pounds For large travel trailers or heavy equipment the Hurricane I6 or the Cummins Diesel choices are considerably better matched
Last Thoughts The landscape of Dodge Ram engines in the USA is changing rapidly While the holler of the V8 is gradually being replaced by the hiss of turbochargers and the hum of electric motors the core mission remains the same supplying American truck owners with the power and reliability they require to finish the job Whether one picks the traditional Cummins diesel for its sheer strength or the new Hurricane I6 for its modernday performance the Ram powertrain lineup continues to be a criteria for the industry
