Background:
From MoparWiki
As used in the Category Models, background can be a brief summary of why the model was created. For instance, if you were to give the background of the Barracuda, you might say something like:
In 1964, Plymouth created a sportier version of their compact/economy Valiant at about the same time as Ford created the sportier Mustang from their compact economy Falcon. These became to be known as Pony Cars.
