These days, we all know what a concept car is. For those who may have occupied the underside of a rock for a while, a concept car is a model that automakers use to showcase things like future design plans, new powertrains, or simply to show the world what the designers were capable of when they had fewer limits. The first model to be considered a “concept car” was the Buick Y-Job, introduced in 1938. It was a design experiment that showcased Buick’s future direction in terms of styling.
