When it comes to heavy-duty pickup trucks, the Ram 2500 stands tall as a formidable contender. With two potent engine options—the 6.4L Hemi V8 and the 6.7L Cummins Turbo Diesel—the Ram 2500 offers a range of capabilities to suit diverse needs. However, one critical factor that differentiates these two engines is their fuel economy, which significantly impacts operating costs and environmental considerations. In this comprehensive guide, we delve into the intricate details of the Ram 2500 6.4 vs 6.7 mpg debate, empowering you to make an informed decision that aligns with your specific requirements.

Power and Performance

The 6.4L Hemi V8 engine delivers impressive power, generating 410 horsepower and 429 lb-ft of torque. This robust engine is ideal for those who prioritize towing and hauling heavy loads. On the other hand, the 6.7L Cummins Turbo Diesel engine reigns supreme in terms of torque, producing a colossal 1,075 lb-ft of torque. This exceptional torque output enables the Ram 2500 to effortlessly handle the most demanding towing and hauling tasks.

Fuel Economy

While both engines offer exceptional capabilities, their fuel economy ratings differ significantly. The 6.4L Hemi V8 engine achieves an EPA-estimated 17 mpg in the city and 23 mpg on the highway. In contrast, the 6.7L Cummins Turbo Diesel engine returns an EPA-estimated 15 mpg in the city and 22 mpg on the highway.

Diesel vs. Gasoline: The Key Differences

Diesel engines are renowned for their superior fuel efficiency and durability. However, they come with a higher upfront cost and require more frequent maintenance. Gasoline engines, on the other hand, are more affordable to purchase and maintain but offer lower fuel economy.

Towing and Hauling Capacity

The 6.4L Hemi V8 engine delivers a maximum towing capacity of 17,540 pounds and a maximum payload capacity of 3,170 pounds. The 6.7L Cummins Turbo Diesel engine boasts an even greater towing capacity of 20,000 pounds and a maximum payload capacity of 3,220 pounds.

Off-Road Capabilities

Both engine options provide excellent off-road capabilities, thanks to the Ram 2500’s rugged construction and advanced suspension systems. However, the 6.7L Cummins Turbo Diesel engine’s superior torque output may provide an advantage in challenging off-road conditions.

Environmental Impact

Diesel engines produce fewer greenhouse gases than gasoline engines, making the 6.7L Cummins Turbo Diesel engine a more environmentally friendly choice. Additionally, diesel fuel contains less energy than gasoline, which contributes to its lower fuel economy.

Which Engine is Right for Me?

The choice between the 6.4L Hemi V8 and the 6.7L Cummins Turbo Diesel engine ultimately depends on your specific needs and preferences. If you prioritize power and performance, the 6.4L Hemi V8 engine is an excellent option. However, if fuel economy, towing capacity, and durability are your top priorities, the 6.7L Cummins Turbo Diesel engine emerges as the superior choice.
