Three-box design
Where the Renault Dauphine is a three-box that carries its engine in the rear and its cargo up front, the styling of the Škoda Octavia integrates a hatchback with the articulation of a three-box. This style was later used by its larger Škoda Superb, which marketed as the TwinDoor, within the liftgate operable as a trunk lid or as a full hatchback. As with the third generation European Ford Escort (also a hatchback), the third box may be vestigial. And three-box styling does not need to be boxy: Car Design News calls the fluid and rounded Fiat Linea a three-box design—and most examples of the markedly bulbous styling of the ponton genre are three-box designs.
