The 3.0L Duramax, officially known as the LM2, was first introduced by General Motors in 2019. Its development was driven by the demand for a more efficient diesel option in lighter-duty trucks and SUVs. GM aimed to combine the towing capacity and fuel economy traditionally associated with diesel engines in a smaller, more refined package. It's currently found in vehicles like the Chevrolet Silverado 1500, GMC Sierra 1500, and the Chevrolet Tahoe and Suburban.
