The 6.5L GM diesel was introduced in 1992, replacing the 6.2L in 1993. Also manufactured by Detroit Diesel, the 6.5 was available in several versions to serve several different applications. The 6.5L, like the 6.2L, was underpowered in comparison to its competitors diesel options, but focused more on providing a fuel efficient alternative. A special "Fuel Miser" version of the 6.5 surfaced in P-trucks (delivery trucks for bread/snack food companies) that produced the fuel mileage of a four cylinder. The 6.5L was offered in naturally aspirated & turbocharged versions. It is still in use today by AM General in the HMMWV military vehicles.
