Chevy is proud to offer diesel engines in much of its lineup. Incorporated into both truck, like the Silverado, and full-size SUVs, you can find a powerful engine in several vehicles, such as:

  • 2023 Chevrolet Tahoe.
  • 2023 Chevrolet Suburban.
  • 2024 Chevrolet Silverado.
  • 2024 Chevrolet Silverado HD.

Diesel Engine Options

When shopping for your next truck, getting a Duramax Diesel engine is sure to beat out the competition with its unmatched power and performance. Chevy offers two different Duramax diesels under the hood. Here’s more about these two impressive engines.

3.0-Liter Duramax Turbo-Diesel

Optimizing fuel efficiency yet still delivering impressive power, the 3.0-liter Duramax turbo-diesel engine can give you anywhere from 277 to 305 horsepower, depending on your vehicle choice. This engine can also pump out between 460 and 495 lb-ft of torque, helping you get the most when you’re trailering. When you’re not hauling, your diesel engine can help you journey further with its astounding EPA-estimated highway range. With this engine, you can get a max range between 672 and 756 miles.

6.6-Liter Duramax Turbo-Diesel

Available on the upper-end Silverado HD, this beast pushes out a whopping 470 horsepower and up to 975 lb-ft of torque. This engine pairs with a 10-speed automatic transmission, offering you astounding power and smooth performance.

Chevy Diesel SUVs

Chevrolet Tahoe

Boasting room and power, the Chevrolet Tahoe has been a main staple of Chevy’s SUV lineup. Offering the choice of the 3.0-liter Duramax turbo-diesel engine in much of the trim lineup for the 2024 model year, you can expect a towing capacity of around 8,000 pounds with the diesel engine.

Regardless of what engine you choose in this beast, it pairs with a 10-speed automatic transmission that has an overdrive system along with a traction select system that includes a tow/haul function. This offers you a smooth ride, regardless of what you’re hauling around, along with a better fuel consumption rating.

Speaking of fuel consumption, with the diesel engine, you can expect an EPA-estimated 21 mpg in the city and 28 mpg on the highway with the two-wheel-drive (2WD) powertrain. If you opt for four-wheel drive (4WD), you can get 20 mpg in the city and 26 mpg on the highway. This beats out the efficiency rating of the other two engine options for the Tahoe, which both get an EPA-estimated 20 mpg on the highway.

Chevrolet Suburban

While the gas engines offer more towing power than the diesel upgrade, opting for the 3.0-liter Duramax turbo-diesel engine still delivers impressive towing capacity along with a better fuel economy rating. Going the diesel route, you can expect a max capacity of around 7,800 pounds on the latest iteration of the Suburban, while the rear-wheel-drive gas engine offers a towing rating of around 8,300 pounds. Regardless of your engine choice, you still need to add on the max trailering package to achieve the full-size SUVs towing potential.

Where this engine really makes a difference in the 2024 Chevrolet Suburban is the fuel efficiency. Both the 5.3-liter and 6.2-liter EcoTec3 V-8 engines offer a max highway rating of 20 mpg. The 3.0-liter Duramax turbo-diesel, however, offers an EPA-estimated 27 mpg on the highway with the 2WD drivetrain. If you opt for the more off-road sturdy 4WD, you can expect a rating of 20 mpg in the city and 26 mpg on the highways.

Diesel Trucks from Chevy

Chevrolet Silverado

Diesel gives the Silverado its strength, and the 2024 model embodies this with its 13,300-pound towing capacity. There are several setups that can help you achieve this impressive hauling feat, one of which requires that you opt for the 3.0-liter turbo-diesel engine along with 20-inch wheels, the max trailering package, and either the double cab standard bed 2WD or crew cab short bed 2WD configuration.

With the 2WD configuration, you can also enjoy better fuel economy than the 4WD variation or the other engine choices. For the 2024 model year, you can get around 23 mpg in the city, 29 mpg on the highway, and an impressive combined rating of 26 mpg. Going the 4WD route, you can expect 23 mpg in the city and 27 mpg on the highway, for a combined rating of 24 mpg.

Chevrolet Silverado HD

The heavy-duty Silverado HD comes in two major variations: the 2500 HD and the 3500 HD. These two offer different towing capacities, making it an important consideration when shopping for your next truck.

Diesel enables the 2024 Silverado 2500 HD to get the most out of its hauling prowess. With the available 6.6-liter Duramax turbo-diesel engine, you can expect a maximum towing capacity of around 22,500 pounds and a max payload capacity of 3,850 pounds. This is up from the gas engine’s 18,700-pound towing capacity and 3,758-pound payload capacity.

If you still want more towing capacity, the 2024 Chevrolet Silverado 3500 HD is the route to go. If you opt for the massive 6.6-liter Duramax turbo-diesel V-8 engine — along with the WT 2WD DRW trim with the regular cab long bed configuration — you can get the class-leading 36,000-pound towing capacity.
