We’re still saying goodbye to diesel trucks, but only one full-size option will be left in 2025. If you want to snag a diesel engine then don’t hesitate. As automakers turn to greener solutions, diesels aren’t making the cut. 

Only 1 full-size truck will have a diesel engine in 2025 

The one full-size truck with a diesel engine in 2025 will be the Chevrolet Silverado 1500. Technically, the GMC Sierra 1500 will also offer diesel power, but the trucks are nearly identical. 

Plus, they will use the same 3.0-liter inline-six Duramax diesel. It provides 305 hp and 495 lb-ft of torque. It’s available with every Silverado trim except for the standard WT model and the Custom. 

The engine currently costs $1,000 more than the gas-powered 5.3-liter V8 engine and $1,000 less than the larger 6.2-liter V8 gas-powered engine. 

When properly equipped, Silverado and Sierra trucks can tow up to 13,300 lbs with the diesel engine. It gets an EPA-estimated 23 mpg in the city and up to 29 mpg on the highway. 

During my week with the TrailBoss model, I hovered around 22.8 mpg. However, the heavier off-roading equipment and larger off-roading tires may have had an impact. Plus, I didn’t have to use my lead foot the entire time.

The 2024 Ford F-150, 2024 Ram 1500, 2024 Toyota Tundra, and 2024 Nissan Titan no longer offer diesel engines. Also, the Titan was officially discontinued earlier this year. 

If you really want diesel power, you don’t have to settle for the Silverado 1500 or Sierra 1500. Heavy-duty trucks like the Ford F-250, Ram 2500 HD, Silverado 3500 HD, and more still have diesel engine options to consider. 

But heavy-duty trucks are more expensive than light-duty options. They’re also larger, meaning they might not be as convenient in the city and other crowded areas. 

It’s unclear how much longer the diesel Silverado and Sierra will hold out. If sales still provide enough funds to make the Duramax engine greener, then it could hang around.
