Yes, the 2021 Chevy Tahoe offers a turbodiesel 3.0-liter I6 LM2 Duramax engine on every trim level except the off-road oriented Z71. This engine was initially designed primarily for use in half-ton pickup trucks, being included in the 2019 Silverado and 2019 GMC Sierra. It’s unofficially, affectionately, known as “baby Duramax.”

The architecture of baby Duramax emphasizes reduced friction and smooth operation. This powerplant is delightfully quiet and buttery at all engine speeds, thanks in part to supporting elements such as a tuned air induction system and other noise-attenuating gizmos.

What other vehicles feature the baby Duramax diesel engine?

Besides the 2021 Tahoe, other vehicles that this turbodiesel I6 has been used in include the abovementioned 2019 GMC Sierra 1500 and 2019 Chevy Silverado, along with the 2021 GMC Yukon, 2021 GMC Yukon XL, 2021 Cadillac Escalade, and 2021 Cadillac Escalade ESV.
