Fuel Efficiency Comparison
The EPA-estimated fuel economy ratings for the Ram 2500 with the 6.4L Hemi V8 and the 6.7L Cummins turbo diesel are as follows:
| Model | City | Highway | Combined |
| — | — | — | — |
| Ram 2500 6.4L Hemi V8 | 14 mpg | 18 mpg | 16 mpg |
| Ram 2500 6.7L Cummins Turbo Diesel | 17 mpg | 23 mpg | 20 mpg |
As you can see, the 6.7L Cummins turbo diesel offers significantly better fuel efficiency than the 6.4L Hemi V8, especially on the highway. This is due to the inherent efficiency of diesel engines, which burn fuel more efficiently than gasoline engines.
Factors Affecting Fuel Economy
In addition to the engine itself, several other factors can impact the fuel economy of the Ram 2500:
- Weight: Heavier trucks require more fuel to move.
- Tire size: Larger tires increase rolling resistance, reducing fuel efficiency.
- Aerodynamics: Trucks with poor aerodynamics experience more wind resistance, which decreases fuel economy.
- Driving habits: Aggressive driving, such as rapid acceleration and hard braking, can reduce fuel efficiency.
Performance Comparison
While fuel efficiency is an important consideration, performance is also crucial for many truck buyers. Here’s a comparison of the performance specs of the Ram 2500 with the 6.4L Hemi V8 and the 6.7L Cummins turbo diesel:
| Model | Towing Capacity | Payload Capacity |
| — | — | — |
| Ram 2500 6.4L Hemi V8 | 17,540 lbs | 4,010 lbs |
| Ram 2500 6.7L Cummins Turbo Diesel | 20,000 lbs | 4,280 lbs |
As you can see, the 6.7L Cummins turbo diesel offers superior towing and payload capacities, making it a better choice for heavy-duty hauling tasks.
Additional Considerations
When choosing between the 6.4L Hemi V8 and the 6.7L Cummins turbo diesel, there are a few additional considerations to keep in mind:
- Fuel cost: Diesel fuel is typically more expensive than gasoline, but the increased fuel efficiency of the Cummins diesel can offset this cost over time.
- Maintenance costs: Diesel engines require more frequent and specialized maintenance than gasoline engines.
- Resale value: Trucks with diesel engines tend to hold their value better than those with gasoline engines.
Recommendations: Making the Right Choice
The choice between the Ram 2500 6.4L Hemi V8 and the 6.7L Cummins turbo diesel depends on your individual needs and priorities. If fuel efficiency is your top concern, the Cummins diesel is the clear winner. However, if you need superior towing and payload capacities, the Hemi V8 might be a better choice. Ultimately, the best way to decide is to test drive both models and see which one best meets your requirements.
