But not to worry, this Ram V6 vs V8 engine comparison article would give you clear insights into choosing the right engine for your Ram truck.

Facts About Dodge Ram V6 Engine

If you’re a getting a brand new Ram 1500 truck, the newer years (talking from 2020) have about two (2) V6 engine options for you to choose from.

However, the base engine is a 3.6L Pentastar V6. Both the base 3.6L Pentastar and the optional 3.0L EcoDiesel V6 delivers good power and stability for all kinds of driving.

The eTorque technology used to fine-tune the base V6 engine on Ram 1500s does a good job in delivering more torque power to the engine; thus, the Ram base V6 engine can deliver 90 pound-feet of launch torque.

If you pick the EcoDiesel V6 engine, it’s still a very powerful engine with the highest fuel efficiency in Ram’s engine lineup.

Facts About Dodge Ram V8 Engine

There are about three (3) V8 engine options to choose from when you decide to go with a V8 engine on your Ram truck.

The most basic V8 option is a 5.7L Hemi engine; it is a notable gas-powered engine engineered with MDS and VVT technologies for higher fuel economy and quit throttle response.

Dodge Ram V6 vs V8 Engines Comparison

1. Fuel Efficiency and Gas Mileage

Many people are interested in the gas mileage they’d get from an engine. Well, generally, V6 engines would give you much better gas mileage and fuel economy.

This is because the V6 engine has fewer cylinders and they are pretty lightweight (meaning they have fewer fuel-consuming components).

However, the V8 engine options for Rams offer decent gas mileage too. Among the 5 engine options available for the Ram 1500 newer models, the EcoDiesel option gives you the highest fuel economy – offering 22 mpg for city driving and 32 on highways – while the supercharged 6.2L HEMI V8 gives the poorest fuel economy.

2. Towing and Hauling

The main reason a lot of people buy pickup trucks is for towing and hauling. Yeah, trucks do a good job in towing and hauling, but there’s a limit to the amount of load you can tow/haul using your truck.

For Rams, you can haul pretty heavy items with the V6 engines; here’s the maximum capacity for each Ram 1500 engine.

3. Performance (Horsepower and Torque)

The horsepower and torque provided by an engine can affect the way you drive. Rams remarkably offer decent horsepower and torque for on-road and off-road driving.

As expected, the V8 engine models offer the most horsepower, but the Pentastar V6 option comes a bit close.

 Engine TypeTechnologyHorsepowerTorque
V6 3.0LEcoDiesel260 HP480 Lb-Ft
V6 3.6LPentastar with eTorque305 HP269 Lb-Ft
V8 5.0LHEMI395 HP410 Lb-Ft
V8 5.7LHEMI with eTorque395 HP410 Lb-Ft
V8 6.2Lsupercharged HEMI720 HP650 Lb-Ft

If you’re going with a V6 engine, you’d get more horsepower with the base Pentastar V6 tuned with eTorque, while the optional EcoDiesel V6 gives you more torque. But for heavier-duty applications, the V8 engine options give you more power all-around.

4. Stability and Comfort

Both V6 and V8 engines offer stability and provide you with good comfort while driving. However, when drifting in corners, accelerating, or driving (generally), V6 engines tend to offer more stability and comfort (less noise).
