2023 Chevy Silverado 1500 and Sierra get new Duramax LZ0 diesel engine

A truck isn’t a truck if it can’t haul and tow. One of the best ways to get monster abilities in a truck is to get a diesel. Ram offers the Cummins, Ford the Power Stroke, and GM offers Duramax diesels in its Chevy and GMC trucks and vans. So if you’re looking for a Chevy Silverado 2500 HD or a GMC Sierra, the big 6.6 is your choice. But for the 1500, GM is ditching the older 3.0-liter Duramax, known internally as the LM2, and replacing it with the next-generation LZ0 for 1500 trucks.
