Chevy will be offering this setup for other full-size SUVs, including the 2021 Suburban. Compared to the Suburban, though, the 2021 Chevy Tahoe has the best fuel efficiency numbers.
First introduced in the 2020 Silverado, the 3.0-liter Duramax turbo-diesel engine utilizes state-of-the-art technology to optimize fuel efficiency. With unique integration for the all-new vehicle architecture, the engine has been adapted to the full-size SUV. It includes enhanced noise abatement and a new engine control module equipped with the ability to take advantage of the faster data-processing power on newer Chevrolet models. For smooth shifting and driving, the engine is coupled with a 10-speed automatic transmission on the 2021 Tahoe.
