Differences Of The Two: 6.4 Hemi Vs 6.7 Cummins

Horsepower

For a certain kind of car, the Hemi is generally more powerful than the 6.7 Cummins. For example, the 410 hp on a 2019 Ram 2500 is an example of this. Faster engine and speed owners choose to utilize this.

Compared to the 6.4 Hemi in the same 2019 Ram 2500 model, the Cummins offers less horsepower (370 hp). Torque output makes it an excellent choice for heavy-duty vehicles. As a result, they’re best suited to heavy-duty vehicles that often tow trailers.

Cost

Because of the high production expenses, Hemi is often more costly whilst the Cummins engine costs less.

Durability

Because of their high durability, Hemi engines may be anticipated to last up to 250000 miles. However, if you don’t regularly haul hefty weights, their lifespan is extended. On the other hand, there is a maximum mileage of 350000 miles for Cummins. Since they are so long-lasting, they are ideal for pulling vehicles.

Torque

On the 2019 Ram 2500, a Hemi delivers 429 lb-ft of torque as a standard. For the same car models, Cummins engines have always been known to provide more torque than the 6.4 Hemi. To put it another way, while using the basic Cummins engine on the 2019 Ram 2500, the engine produced 855lb-ft of torque.

Towing Capacity

Hemi’s maximum towing capacity for the 2019 Ram 2500 was 16,320 pounds. As a result, the engine’s maximum speed would be limited to 35mph when hauling a big cargo up an inclining road for a lengthy period.

On a 2019 Ram 2500, Cummins can haul a whopping 19780 lbs thanks to its powerful engines. In addition, an air-leveling rear suspension is supported, which lets the vehicle adjust to shifting loads or situations. If you’re going to be hauling a lot of weight, a Cummins engine could be a better choice.

Fuel Efficiency

The Multi-Displacement System (MDS) engineering in a Hemi helped to drastically reduce gas usage. When not in use, up to four of the engine’s eight cylinders are turned off. Fuel pumping losses may be reduced by turning off the cylinders’ fuel supply.

As a result, Cummins provides superior fuel management and a higher MPG of 17.5, compared to 15.7 MPG for the 6.4 Hemi on the Dodge Ram 2500 when tested.

Payload Capacity

For the 2019 Ram 2500, Hemi delivers a maximum payload capacity of 4050 pounds. Because of its high-speed automatic gearbox, this is feasible.

The cargo capacity of the 2019 Ram 2500 is marginally reduced when powered by a Cummins engine. The total weight was 3260 pounds. However, this engine’s towing capacity was increased as a result of a greater torque rating.

Mileage

The cumulative mileage of a Hemi may reach up to 250,000 miles or more with proper usage and care. Heavy towing, on the other hand, usually results in a much worse gas economy than light towing.

For Ram pickups, Cummins can drive up to 350000 miles on a single charge. Regular engine maintenance, on the other hand, is required regularly.

Maintenance

Oil filters may be cleaned or a spare air filter can be kept on hand for Hemi’s basic maintenance. Furthermore, you should only use the prescribed oil.

Cummins demands extra maintenance, such as EGR coolers, head gaskets, and so forth. In addition, it is required to do routine maintenance on the air filter.
