Station wagon

A station wagon, also called an estate car, estate wagon, or simply wagon or estate, 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.

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."

When a model range includes multiple body styles, such as sedan, hatchback and station wagon, the models typically share their platform, drivetrain and bodywork forward of the A-pillar. In 1969, Popular Mechanics said, "Station wagon-style ... follows that of the production sedan of which it is the counterpart. Most are on the same wheelbase, offer the same transmission and engine options, and the same comfort and convenience options."

Station wagons have evolved from their early use as specialized vehicles to carry people and luggage to and from a train station, and have been marketed worldwide.

Station wagon and wagon are the common names in American, Canadian, New Zealand, Australian and African English, while estate car and estate are common in the rest of the English-speaking world. Both names harken to the car's role as a shuttle, with storage space for baggage, between country estates and train stations.
