The catastrophic failure of a new but unproven copper-cooled Chevrolet in 1923 led the General Motors Corporation to buy back the 100 cars it had sold to the public and recall another 400 in company and dealer hands. As a result, in 1924 General Motors started building the industry's first scientific proving ground to test new vehicle designs before they were released for production and sale. Before this, all automakers tested new cars haphazardly on public roads and within limited engineering laboratories. Better known by the public as test tracks, the proving grounds became a source of curiosity for decades about the secrets they might hold. Detroit Area Test Tracks goes behind the test track walls to show how the facilities evolved and what typically takes place inside.
