A coupé is a two-door version of a four-door saloon car or a fixed-roof version of a convertible.

The word comes from the French couper, to cut, and indicates that a coupé is normally a shortened version of the vehicle. However, this aspect of the term has largely been forgotten and some cars regarded as coupés are no shorter than the saloons on which they are based. The Peugeot 405 coupé was actually longer than its saloon progenitor.
