However, consistently highly-rated and frequently cited contenders for best diesel pickup truck engine include:
* Cummins (various): Cummins engines, particularly those found in Ram trucks (like the 6.7L), have a strong reputation for power, towing capacity, and longevity. They're often praised for their robustness and reliability, though they can be less refined than some competitors.
* Ford Power Stroke (various): Ford's Power Stroke engines (like the 6.7L) are known for their strong performance and advanced technology. They often deliver a good balance of power, fuel economy, and refinement.
* Duramax (various): GM's Duramax engines (like the 6.6L) are another popular choice, often praised for their balance of power and fuel efficiency. They've seen improvements in refinement over the years.
Factors to consider when choosing:
* Towing capacity: If you need to tow heavy loads, towing capacity is paramount. Larger displacement engines generally offer more towing power.
* Fuel economy: Fuel costs can add up quickly. Look for engines with good EPA estimates. Real-world fuel economy can vary depending on driving style and conditions.
* Reliability: Some engines have a better track record for reliability than others. Research reported issues and owner experiences.
* Maintenance costs: Diesel engines generally require more maintenance than gasoline engines. Consider the long-term maintenance costs.
* Refinement: Some diesel engines are quieter and smoother than others. If a refined driving experience is important, consider this factor.
* Technology: Modern diesel engines often incorporate advanced technologies like selective catalytic reduction (SCR) and diesel particulate filters (DPF) to reduce emissions. These systems can add complexity and potential maintenance needs.
Ultimately, the best diesel pickup truck engine for *you* will depend on your individual needs and priorities. Research specific engine specifications and read owner reviews to make an informed decision. Consider test driving different trucks to experience the differences firsthand.
