The 2021 Chevrolet Tahoe 3.0L Duramax turbo-diesel is the most fuel-efficient full-size SUV in its class1. Better fuel efficiency supports longer trips in this best-selling nameplate known for its size, capability and cargo.

The Chevrolet Tahoe with the available 3.0L Duramax turbo-diesel engine offers an EPA-estimated 28 highway, 21 city and 24 combined mpg in rear-wheel-drive models. EPA-estimated fuel economy for four-wheel drive models is 26 highway, 20 city and 22 combined mpg.

This is Chevy’s first diesel inline-six engine for full-size SUVs, and the brand’s first diesel offered in full-size SUVs since 1999. In the Suburban, the 3.0L Duramax offers an EPA estimated 27 highway, 21 city and 23 combined mpg in two-wheel drive models and 26 highway, 20 city and 22 combined mpg in four-wheel drive models.

The 3.0L Duramax turbo-diesel launched first in the 2020 Silverado, utilizing state-of-the-art technologies to optimize fuel and integrate into the all-new vehicle architecture. Small changes adapt the engine for the full-size SUV application, including enhanced noise abatement and a new engine control module, specifically designed to leverage the faster data-processing power of the all-new models. The engine is exclusively paired with a 10-speed automatic transmission for a smooth shifting experience.

With an SAE-certified 277 horsepower and 460 lb-ft of torque, the Tahoe 3.0L Duramax with two-wheel drive is capable of maximum towing up to 8,200 pounds and a max payload of 1,717 pounds2. The Suburban with the same engine is capable of a maximum towing of 8,000 pounds and a max payload of 1,625 pounds in two-wheel drive models. A standard exhaust brake is available in tow-haul mode and can provide additional driver confidence when towing.

The driver-selectable stop/start technology optimizes fuel economy by shutting off the engine at stoplights and certain other stop-and-go situations, helping to save fuel.

The 3.0L Duramax turbo-diesel is available on the LS, LT, RST and Premier trims with an MSRP3 of $995 over the base 5.3L V-8 gas engine. It is also available in the High Country trim as a $1,500 MSRP decrease over the standard 6.2L V-8 gas engine.

The first customer deliveries of the 2021 Tahoe and Suburban with the available 3.0L Duramax turbo-diesel are expected to begin before the end of the year.
