The General Motors–Detroit Diesel V8 engine is a series of diesel V8 engines first introduced by General Motors for their C/K pickup trucks in 1982. Developed in collaboration with GM subsidiary Detroit Diesel, the engine family was produced by GM through 2002, when it was replaced by the new Duramax line. AM General's subsidiary General Engine Products (GEP) still produces a military variant of this engine for the HMMWV.[1]

The General Motors light-truck 6.2L and 6.5L diesel engines were optional in many 1982 through 2002 full-size GM pickups, SUVs, and vans. They were also available in motor homes. The engine was standard on AM General's military HMMWV, civilian Hummer H1, and the 1980s GM military Commercial Utility Cargo Vehicle.
