The Detroit Series 92 (especially in 6V92TA form) is a favorite of mine in the history of diesel transport. The local Metro bus line replaced old Series-71 equipped GMs with Gilligs in the early 80's. The engine was marketed as a "fuel miser" and was built on the reliability of the previous-gen 71-series. It lacked power, but got the job done. Electronic engine and transmission control improved FE and emissions until the engine was discontinued and replaced by the Series 60, 4-stroke.
Environmentally, the 2-stroke, turbo-aftercooled plant was an emissions nightmare, but served the purpose for the era and offered superior FE compared with older equipment (well into the 90's). Plus there's just something unique about the sound of a 6V-92. Day after day, I heard the passing buses pull a hill from a standing start, which became a familiar routine of "neighborhood sounds" for years.
Anyways, the more gears the better -- 6-speed automatics are becoming more common in cars (borrowing on the torque curve argument)...
