station wagon

A station wagon (US, also wagon) or estate car (UK, also estate) is an automotive body-style variant of a sedan 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/boot 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.

The American Heritage Dictionary defines a station wagon as "an automobile with one or more rows of folding or removable seats behind the driver and no luggage compartment but an area behind the seats into which suitcases, parcels, etc., can be loaded through a tailgate."
