Deep in German mud, this M-24 has left its imprint of Cadillac power. For, like more than 10,000 tanks that have gone before it, the M-24 is powered by two Cadillac V-type engines, driving through two Cadillac Hydra-Matic transmissions.
It is no longer a secret that tanks built and powered by Cadillac have long been laying tracks to Victory in every battle sector of the globe. For, with the help of Army Ordnance Engineers, we started building tanks for Army use more than 3 years ago. We have been steadily at it ever since.
The success of the Cadillac V-type engine and Hydra-Matic transmission in powering tanks —the ease with which these power units were adapted to tank use—and their inherent ability to bring a new degree of maneuverability to tank warfare—are all conclusive evidence of their fundamental soundness of design. Abnormal wartime use has subjected both engine and transmission to tests never encountered in civilian service. As a result, they have been improved in many ways.
