Ever since the Ram 2500 debuted in the late '90s, it has been confidently taking on the tasks that other trucks shy away from. Its impeccable towing capacity and rugged build allow it to be a key member of work fleets across the nation. What’s more is that, with its cozy cabin, tackling a long haul for work will be more enjoyable than you ever thought possible in a work truck.

Why Choose a HEMI Engine?

So, now that you know how amazing the Ram 2500 is, should you choose the HEMI V8 or the Cummins Turbo-Diesel to help you move forward with confidence? Well, the standard engine on the 2024 Ram 2500 is the 6.4L HEMI V8, which outputs up to 410 hp and 429 lb-ft of torque.

Not only does this engine deliver an exciting ride, but it can also tow up to 17,730 lbs, helping you take on more tough tasks during the day, especially on the job site. This powertrain also allows you to handle up to 4,000 lbs of payload, perfect for loading up your truck with heavy materials for a project.

HEMI engines are ideal in a variety of situations, especially when it comes to work. The power that radiates out of these impressive engines is top-of-the-line, so when it comes to doing big tasks efficiently, HEMIs are at the top of their class.

Thanks to a hemispherical design, HEMI engines burn fuel more effectively, with a smaller surface area due to its shape, allowing less heat to escape during the combustion process. These engines also include larger valves, which improve airflow, allowing your truck to operate at its peak at all times. Efficient cooling and use of its fuel make the HEMI one of the best engines to choose for peak performance.

The Ram 2500’s 6.4L HEMI V8 is paired with an eight-speed automatic transmission, adding smoother control to the drive that you won’t find elsewhere. Gas-powered V8 engines also tend to be a bit quieter than their diesel counterparts, allowing you to enjoy a more peaceful cabin experience. If you’re looking for an engine that’s powerful yet refined, the HEMI V8 may be exactly what you’re looking for in your Ram 2500.

Why Choose the Cummins Turbo-Diesel?

Cummins and Ram go together like butter and toast, and when it comes to completing tough tasks, nothing is better than a diesel. Diesel engines are not only more powerful than their V8 competitors, but they’re also highly efficient, proving themselves graceful on the highway and beyond, allowing drivers to take advantage of a level of performance and fuel economy that can’t be beaten.

The 2024 Ram 2500 can be armed with an available 6.7L Cummins Turbo-Diesel inline-six, which offers 370 hp and an astounding 850 lb-ft of torque to the drive. This allows the Ram 2500 to tow up to 19,990 lbs and handle up to 3,150 lbs of payload. It’s clear that the Cummins Turbo-Diesel excels when it comes to towing; however, it is a bit slower off the line—but this usually isn’t a reason to be dissuaded from the Cummins.

Diesel engines come with a host of advantages that make them top picks with heavy-duty drivers across the nation. In addition to exceptional fuel economy, diesel engines prioritize torque, which helps them tow more than other types of engines. They also require less maintenance due to the fact that there are fewer components comprising these skilled engines. You’ll also find that diesels are built to last, offering levels of reliability far past other types of powertrains available.

Ram pairs its spectacular Cummins Turbo-Diesel with a six-speed automatic transmission, which presents an accurate and responsive ride, perfect for those who require more out of their truck. Unlike many other diesel engines, this particular powertrain also offers a rather quiet ride, which is a big win for drivers who want to be able to sit back and relax during their journey.

If you’re searching for a truck that’s strong, efficient, and ready for anything, arming your Ram 2500 with the Cummins Turbo-Diesel will allow you to enjoy one of the best driving experiences possible.

HEMI vs Cummins: Which Should You Choose?

There’s no doubt about it: both of these engines are incredible, able to provide the power needed to complete challenges while also providing the refinement you’re looking for behind the wheel.

If you want a truck that’s quick off the line while also being a strong tower and hauler, the HEMI V8 may be right for you. If you need to be able to tow heavier loads with precision while maximizing fuel efficiency, the Cummins Turbo-Diesel may be your ideal pick.

Either engine will change the way you drive, offering a performance that you won’t find in others, allowing you to make the most out of whatever challenge you take on next.
