The Detroit Diesel history began in 1938, just as World War II was heating up. That year, General Motors formed the GM Diesel Division — the ancestor to Detroit Diesel. The needs of tanks, landing craft, road building equipment and standby generators meant our first engines had to be compact, lightweight, two-cycle products. It was during this epic time that a tradition of strength, quality and dependability was born.
