9 pickup trucks you can still order with a diesel engine

Diesel engines used to be the default choice for serious towing, but automakers have trimmed their oil-burning lineups as buyers shift toward gas and electric options. A handful of heavy-duty and light-duty pickups still offer a factory diesel, from six-cylinder Cummins and Duramax setups to Ford’s V-8 Power Stroke. Here are nine trucks that still let a buyer check the diesel box.

1. Ram 2500 Heavy Duty: The $12,595 Cummins Option

Ram’s heavy-duty pickup still offers the 6.7-liter Cummins turbo-diesel inline-six as a factory option, according to Car and Driver’s Ram coverage, priced at $12,595 and rated at 430 horsepower and 1,075 pound-feet of torque, output that has stayed near the top of the heavy-duty segment for years.

That torque arrives low in the rev range, which is why the option remains popular for gooseneck and fifth-wheel towing, even as most buyers on the dealer lot still choose the standard gas V-8 for everyday driving, lighter loads, and a lower sticker price.

2. Ram 3500: Still Rated At 430 Horsepower

The 2026 Ram 3500 keeps the same Cummins-based option sheet as its 2500 sibling, and J.D. Power’s 2026 Ram 3500 listing shows an intercooled turbo-diesel inline-six rated as high as 430 horsepower alongside a standard gasoline V-8 that ships on far more trucks off the lot.

The dually-capable 3500 trades some of the 2500’s daily drivability for higher payload and towing ceilings, and the diesel inline-six remains the engine buyers pick when a truck needs to pull a loaded gooseneck trailer across mountain grades without downshifting constantly.

3. Ford F-250 Super Duty: A 500-Horsepower Power Stroke

Ford still fits the F-250 with the 6.7-liter Power Stroke diesel V-8, and in its high-output tune Car and Driver’s Super Duty coverage lists the engine at 500 horsepower and 1,200 pound-feet of torque, among the strongest factory diesel ratings in a pickup this size.

The low-output version of the same V-8 is offered as a less expensive step up from the base gas engine, giving buyers a choice between maximum towing capability and a lower price on the option sheet, a trade-off unique to the Super Duty line among heavy-duty domestic pickups.

4. Ford F-350 Super Duty: Diesel On Every Trim Level

The F-350 shares its diesel option sheet with the smaller F-250, and Car and Driver’s Super Duty review confirms every F-350 trim can be ordered with the 6.7-liter Power Stroke V-8, in either the low-output or high-output tune Ford builds for the Super Duty lineup.

That consistency matters for fleet buyers and contractors who want the same drivetrain across a mixed lineup of trucks, whether the truck rides on single rear wheels or the dual-wheel dually setup that raises payload and towing capacity further, depending on the configuration a buyer specs at order time.

5. Ford F-450 Super Duty: No Gas Engine Offered

Ford does not give F-450 buyers a gasoline option at all: J.D. Power’s 2026 F-450 listing names a single engine, an intercooled turbo-diesel V-8 rated between 475 and 500 horsepower depending on the specific trim and configuration ordered.

Because the F-450 is built around commercial and chassis-cab work, from tow trucks to large campers, the diesel-only lineup reflects how few buyers at this weight class would ever consider a gas-powered alternative for daily heavy-duty hauling, towing gooseneck trailers, or running a loaded flatbed body through a full workday.

6. Chevrolet Silverado 2500HD: The Allison-Paired Duramax

Chevrolet still pairs the Silverado 2500HD with the Duramax 6.6-liter Turbo-Diesel V8, and Chevrolet’s own Silverado HD page rates the engine at 470 horsepower and 975 pound-feet of torque when it is mated to the Allison 10-speed automatic transmission.

That transmission pairing is part of why the Duramax remains the default choice for buyers hauling horse trailers or construction equipment, even though the standard 6.6-liter gas V-8 costs thousands less at the dealership and returns better fuel economy for buyers who rarely tow near the truck’s rated limits.

7. GMC Sierra 3500HD: Rated To Tow 36,000 Pounds

The Sierra 3500HD carries the same Duramax 6.6-liter Turbo-Diesel V8 as its Chevrolet counterpart, and GMC’s Sierra HD page pairs it with an Allison 10-speed automatic for a maximum towing rating of 36,000 pounds, matching the segment-leading number Ram and Ford also claim for their heaviest trims.

That figure sits at the top of the heavy-duty pickup class and is aimed squarely at buyers pulling gooseneck livestock trailers, large fifth-wheel campers, or flatbed equipment trailers that would overwhelm a half-ton truck’s gas engine, especially on long highway grades where sustained pulling power matters most.

8. Chevrolet Silverado 1500: The Only Light-Duty Diesel

Diesel power is not limited to the heavy-duty trucks: Chevrolet’s Silverado 1500 page lists the Duramax 3.0-liter Turbo-Diesel as an available engine and calls it the only diesel offered in the light-duty pickup class, rated at 28 miles per gallon on the highway.

That mileage figure is well above what the Silverado’s gas V-8 options return, which is why the light-duty diesel appeals to owners who tow occasionally but drive most miles unloaded and want to cut fuel costs without giving up a half-ton truck’s cargo box and crew-cab space.

9. GMC Sierra 1500 Denali: Denali Trim, Diesel Six

Buyers who want a diesel in GMC’s upscale Denali trim are not out of luck: J.D. Power’s Sierra 1500 review lists the Duramax 3.0-liter turbodiesel inline-six at 305 horsepower and 495 pound-feet of torque, with a combined EPA rating of 25 miles per gallon.

That combination of light-duty comfort features, a quiet cabin, and a torque-heavy diesel under the hood is the appeal of the Sierra 1500 Denali, which mixes highway efficiency with enough pulling power for a mid-size camper or boat without the ride harshness of a heavy-duty truck.
