Aluminum (automobile)

The Aluminum was an American automobile built by the Aluminum Manufacturers, Inc. of Cleveland, from 1920 to 1922. The car was manufactured primarily as an experiment, in an attempt to prove that aluminum could be used in the construction of automobiles. Six cars were built; each was a five-passenger touring car weighing 2400 lb (1100 kg) and featuring a 126-inch (3.20 m) wheelbase and a four-cylinder Alcoa engine. In 1922 Pierce-Arrow became involved in the company, and all cars built after that point were constructed under Pierce-Arrow's aegis and bore the name Pomeroy.

In an unrelated incident, in 1988, when the soon-to-be-introduced Lumina model became the nameplate under which Chevrolet was to compete in NASCAR, irate fans bombarded NASCAR with letters protesting the unfairness of Chevrolet being allowed to race an aluminum car.
