Sedan

A sedan, known in British English as a saloon, is a passenger car built to the classic three-box formula: a separate compartment for the engine at the front, a central cabin for the occupants, and a distinct, sealed boot at the rear. The defining feature is that final box. Unlike a hatchback, whose rear glass lifts as part of a single tailgate, a saloon has a fixed rear window and a separate boot lid, so the luggage area is fully partitioned from the passenger compartment. This clean division of functions has made the saloon one of the oldest and most enduring car shapes.

The sealed boot is more than a styling choice; it brings tangible benefits. Because the rear cabin is closed off by a solid bulkhead and parcel shelf rather than left open to the load area, a saloon tends to be quieter and more refined than an equivalent hatchback, with less road and tyre noise reaching the occupants and a structure that can feel more rigid. The boot itself, set low and long beneath the rear screen, often holds a larger total volume than a hatchback's, lending the saloon a reputation for comfortable, hushed long-distance travel.

These qualities explain the saloon's enduring popularity in the executive and luxury segments. Refinement, a settled ride and an air of formality suit cars intended for business travel and chauffeur-driven use, and many of the most prestigious models, from the BMW 3 and 5 Series to the Mercedes-Benz E-Class and S-Class, are saloons at heart. The three-box silhouette also lends itself to balanced, dignified proportions that buyers in these classes value.

The trade-off lies in flexibility. Although the boot is voluminous, access is through a comparatively small opening beneath the fixed rear glass, which makes loading tall or bulky items far harder than through a hatchback's wide aperture or an estate's square tailgate. Folding rear seats mitigate this on many modern saloons, but the fundamental shape still favours suitcases over wardrobes. This is the central practical compromise that buyers weigh when choosing between a saloon and a more versatile body style.

Across the wider family of body styles the saloon serves as a useful reference point. It shares its three-box proportions with the two-door coupé, which sacrifices rear practicality for sleeker looks, and forms the basis of the estate, which extends the roofline over the boot to create a large, flexible load bay. It sits at the core of the executive-car class, and it contrasts most directly with the liftback, which keeps the saloon's elegant shape but replaces the fixed boot with a large lifting tailgate to combine refinement with hatchback-style access.
