Ram Trucks Fuel Economy Guide

Ram Trucks Fuel Economy - Germain CDJR

You already know that Ram trucks offer incredible capability, not to mention the best truck interiors in the business. But what about fuel economy? Most Ram truck guides focus on things like towing capacity. But since we already covered that elsewhere, we put together a guide to Ram fuel economy, so you can have the whole picture.

Ram 1500 Fuel Economy

Ram 3500 Towing




Fuel Economy (city / highway / combined)

3.6L Pentastar® V6


273 lb-ft 20 / 26 / 23
5.7L HEMI® V8


410 lb-ft 18 / 23 / 20
Supercharged 6.2L HEMI® V8


650 lb-ft 10 / 14 / 12

For most trims of the 1500, the base engine is a 3.6-liter V6. This is a robust engine, and it puts out plenty of power for what most people use their 1500s to do. But for people who need more power, the available 5.7-liter V8 puts out noticeably more torque and horsepower both, yet the fuel economy tradeoff isn’t nearly as big. Although it isn’t the most powerful engine option, the 5.7 V8 is usually the preferred option for 1500s configured for towing. That’s because the more powerful supercharged 6.2-liter V8 is available only in the TRX, and although the TRX has a respectable towing capacity, it’s meant more for offroad performance.

Ram Commercial Vehicles

The rest of the Ram lineup is classified as commercial, and therefore exempt from EPA reporting on fuel economy. But even though we don’t have fuel economy data on the ProMaster, 2500 or 3500, we can still show how much power the engines in these vehicles make:

Ram 3500 Towing





3.6L Pentastar® V6


250 lb-ft

2500 / 3500

6.4L HEMI® V8


429 lb-ft
6.7L Cummins® Turbo Diesel I6


850 lb-ft
High-Output 6.7L Cummins® Turbo Diesel I6 (3500 only)


1,075 lb-ft

As you can see, there is a wide variety of engines available for Ram commercial vehicles, thanks to an even wider range of applications for these highly versatile vehicles. You might have noticed that the 3.6-liter V6 in the ProMaster produces slightly less power than the 3.6-liter V6 in the 1500. That’s because, as a commercial vehicle that is expected to be part of a fleet, the ProMaster engine is tuned to be as low maintenance as possible, and that’s why the ProMaster only needs servicing every 10,000 miles.

When it comes to towing, truck buyers tend to prefer diesel engines, and one look at the torque produced by the Cummins® diesel engines offered for heavy-duty Ram trucks makes it immediately clear why. The incredible torque produced by these engines is why the 3500 has a maximum towing capacity of 37,090 pounds, an incredible feat. Whatever your needs, there is a Ram commercial vehicle that can make the job easier.
