Chevrolet Series M Copper-Cooled

The 1923 Chevrolet Series M Copper-Cooled was an automobile made to be completely air-cooled by Chevrolet in 1923. It was designed by Charles F. Kettering, head engineer of Delco, the General Motors research division wing in Dayton, Ohio. The automobile used a body style from its predecessor, but incorporated an air-cooled engine. Air cooling, as opposed to water-based cooling, was much more practical in a sense because it did not require a radiator, nor the piping that came with it. Although air cooling was not new to the time period, it was new to engines of that scale. The Copper-Cooled Chevrolet was in fact a feasible project; however, the final product did not live up to the standards that Kettering had imagined. The car dangerously overheated in hot weather, and posed a safety hazard to the drivers. Only a few made it to the sales floor, only to be recalled and destroyed by Chevrolet. The 1923 Chevrolet Series M Copper-Cooled consumed extensive amounts of resources to develop and was a failure in the end. The engine was manufactured as an alternative to the Franklin which also used an in-line air-cooled engine.
