A
station wagon, also called an
estate car,
estate wagon, or simply
wagon, is an automotive
body-style variant of a
sedan/saloon with its roof extended rearward over a shared passenger/cargo volume with access at the back via a third or fifth door (the
liftgate or tailgate), instead of a trunk lid. The body style transforms a standard
three-box design into a two-box design — to include an
A, B, and C-pillar, as well as a D-pillar. Station wagons can flexibly reconfigure their interior volume via fold-down rear seats to prioritize either passenger or cargo volume.
