6.2L fitted to a 1987 HMMWV. The original 6.2 L (379 cu in) diesel V8 was introduced in 1982 for the Chevrolet C/K and was produced until 1993. The 6.2L diesel emerged as a high-fuel-economy alternative to the V8 gasoline engine lineup, and achieved better mileage than Chevrolet's 4.3L V6 gasoline engine of the 1980s, at a time when the market was focused on power rather than efficiency.
After 2016, the 6.6 L Duramax diesel V8 was discontinued; a 2.8 L inline-4 Duramax (the first four-cylinder in a full-size Chevrolet van since 1964) replaced it as the diesel engine offering. For 2018, an "EcoTec3" 4.3 L V6 was introduced as the base gasoline engine; the same year, CNG/LPG capability was added as an option to the 6.0 L V8.

During the latter years of production, 379-and-432-cubic-inch (6.2 and 7.1 L) versions with enlarged crankshaft journals were manufactured as well.
