A notchback full-size luxury sedan.
A 'sedan'
car,
American English terminology ('saloon' in
British English), is one of the most common
body styles of the modern automobile. At its most basic, the sedan is a passenger car with two rows of seats and adequate passenger space in the rear compartment for adult passengers. The vehicle has a separate
trunk ('boot' in British English), for luggage at the rear.
Types of sedan

The 3-box design, indicative of a notchback sedan, as illustrated on a full-size luxury sedan.
Several versions of the body style exist, including four-door, two-door, and
fastback models.
A sedan seats four or more and has a fixed roof that is full-height up to the rear window. The roof structure will typically have a fixed "B"
pillar on sedan models. Most commonly it is a four-door; two-door models are rare, but they do occur (more so historically). In the U.S., this term has been used to denote a car with fixed window frames, as opposed to the
hardtop style without a "B" pillar and where the sash, if any, winds down with the glass. However, true hardtops have become increasingly rare.
Notchback sedans
A
notchback sedan is a 'three-box' sedan, where the passenger volume is very distinct from the trunk volume of the vehicle (when seen from the side). The roof is on one plane, generally parallel to the ground, the rear window at a sharp angle to the roof, and the trunk lid is also parallel to the ground. Historically, this has been a very popular and traditional form of passenger vehicle.
Fastback sedans

A
fastback sedan is a 'two-box' sedan, with continuous slope from the roof to the base of the
decklid, but excludes the
hatchback feature.
Marketing terminology is often misleading in this area - for example
DaimlerChrysler calls the
Mercedes-Benz CLS-Class sedan a ''four-door coupe,'' because of its semi-fastback design tries to give the impression of a coupe. Certain sedans are edging close to being ''one-box'' vehicles, where the windshield is steeply raked from the hood and the rear window slopes toward almost the end of the car, leaving just a short rear deck that is part of the trunk lid - the 2006 4-door
Honda Civic is an example of this. They are not fastbacks because their bodyline changes from the roof to the rear deck. Their steeply raked rear windows end with a
decklid that does not continue down to the bumper. Instead, their rear ends are tall - sometimes in a
Kammback style - to increase
trunk space.
Typically this design is chosen for its
aerodynamic advantages. Automakers can no longer afford the penalty in
fuel consumption produced by the traditional
notchback ''three box'' form.
Two-door sedan

A traditional two-door sedan, 1959
Rambler American with a B-pillar and fixed window frames.
The
SAE defines such a vehicle as any two-door model with rear accommodation greater than or equal to 33 cubic feet (0.934 m³) in volume (a calculation made by adding the legroom, shoulder room, and headroom). By this standard, the
Chevrolet Monte Carlo,
Ferrari 612 Scaglietti, and
Mercedes-Benz CL-Class coupes are all two-door sedans. Only a few sources, however (including the magazine ''
Car and Driver''), use the ''two-door sedan'' label in this manner.
In the popular vernacular, a two-door sedan is defined by appearance and not by volume; vehicles with a B-pillar between the front and rear windows are generally called two-door sedans, while hardtops (without the pillar, and often incorporating a sloping backlight) are called coupés.
The
Mazda RX-8 meets the volume requirement to be called a sedan, but it has vestigial rear-hinged rear doors, so some call it ''2+2-door sedan''. Another term for a coupé endowed with rear-hinged doors is a "quad coupé". Although this may simply be vernacular, based on a possible copyright by ''
General Motors'', for its ''
Saturn ION Quad-Coupé''.
Hardtop sedans
In historic terminology a sedan will have a frame around the door windows, while the
hardtop has frameless door glass. A true
hardtop sedan design also has no "B" pillar (the roof support behind the front doors). This body style has an open feel, but requires extra underbody strengthening for structural rigidity. The hardtop design can be considered separately (i.e., a vehicle can be simply called a four-door hardtop), or it can be called a hardtop sedan. During the 1960s and 1970s, hardtop sedans were often sold as ''sport sedans'' by American manufacturers and were very popular. During the 1980s, automakers in the U.S. focused on removing weight and increasing strength, and new four-door sedans with B-pillars were called ''pillared hardtops'' or ''pillared sedans''. The ''sport sedan'' term has since been appropriated for other uses. In Japan, and among Japanese manufacturers worldwide, the hardtop design was quite popular among luxury sedans throughout the 1990s.
Hatchback sedan

Chevy Malibu Maxx (on Saab chassis)
Hatchback (a.k.a.
liftback) sedans typically have the
fastback profile, but instead of a trunk lid, the entire back of the vehicle lifts up (using a liftgate or hatch). A vehicle with four passenger doors and a liftgate at the rear can be called a four-door hatchback, four-door hatchback sedan, or five-door sedan. An example of such is the
Chevrolet Malibu Maxx. There can also be two-door hatchback sedans (three-door sedans), by the same technical explanation for two-door sedans. Examples of this design are the
Volkswagen Golf,
Toyota Celica, and
Renault Vel Satis.
Chauffeured sedans

The Lincoln Town Car is the most commonly chauffeured car in the US.
Chauffeured
limousine sedans are primarily used by businesses for meetings as well as for airport transportation. Main vehicles used for these means are usually the
Lincoln Town Car, a
Cadillac, or a
Mercedes.
Chauffeurs are professional drivers, usually with experience in the
transportation industry or
tourism industry. Chauffeured sedans are owned either by private owners, livery services, or corporations. Large corporations as well as governments commonly provide luxury sedans to their top executives as well as VIP guests. Chauffeured sedans, especially the Lincoln Town Car, may also be stretched into limousines that are capable of seating up to twenty people. Another, smaller number of chauffeured sedans are owned by private individuals who hire chauffeurs to drive them in their own cars.
Manufacturers and configurations
Currently(in 21st century) high end and luxury sedans by manufacturers
Mercedes,
BMW are
rear wheel drive(with
FR layout), ultra luxury segment also follows the same. Low end sedans by manufacturers
Toyota,
Ford,
Honda,
GM are
front wheel drive(with
FF layout), these form majority in number. High end sedans of
Audi are Front wheel drive with longitudinal engine stand as exception. Rear wheel drive sedans fall in price band above around US $50,000, though it is not necessarily true in all cases.
Terminology

Sede chair carried by two people
Origin
Main articles: Litter (vehicle)
The word ''sedan'' is possibly derived from a southern
Italian dialect derivative of Italian ''sede'' "chair" (the first sedan was said to have been introduced from
Naples). However,
Portuguese and
Spanish navigators and colonists encountered
litters of various sorts in
India,
Mexico, and
Peru. They were imported into
Spain in the late sixteenth century. Soon the fashion spread into
France and then
England. All the names for these derived from the root "sed-" from the
Latin "sella" - the traditional name for a carried chair.
[1]
The derivation from the town of
Sedan in France, where it was said to have been made or first used, lacks historical evidence, according to
OED. The word ''sedan'' was later used to refer to a litter or windowed box containing a passenger seat carried by two or more bearers.
International terminology
In
North American English and American Spanish, the term sedan is used.
In
British English the configuration is called a 'saloon' and has its engine under the ''bonnet'' at the front, and a ''boot'' for luggage at the rear. The British English term is sometimes used by British car manufacturers in the United States. For example, the
Rolls-Royce Park Ward was sold as a saloon in the United States, while the smaller
Silver Seraph was called a sedan.
In
Australia and
New Zealand, the American term sedan is used, albeit with the British terms ''boot'' and ''bonnet'' being retained. In other languages, sedans are known as 'berline' (
French), 'Berlina' (
Spanish,
European Portuguese,
Romanian, and
Italian); although these terms also may include hatchbacks. These terms, besides sedan, derive from types of
horse-drawn
carriages. In
German, the term 'Limousine' is used for sedans whereas the term ''Stretch-Limousine'' is used for
limousines.
