Difference Between a Coupe and a Sedan (With Table)

A car is an automobile that runs primarily on the road, has 2-8 seats, has four wheels, and is used for transportation for humans and not goods. The invention of cars in the 20th century has made it so popular that every economy is dependent upon it in modern times. In the year 1886, cars were invented for the first time by Karl Benz. Cars are usually associated with comfortability, parking, driving, features, control, ease to operate, etc. Cars come in many models, among which a coupe and a sedan are common.

Coupe vs Sedan

The difference between a coupe and a sedan is that a coupe car is usually shorter in length and has small doors and windows. While a sedan is longer, that gives it luxury and comfortability over a coupe. A sedan has more cargo space for carrying additional luggage and passengers. A coupe is generally considered sportier as it can have only 2 seats for driving with less interior and more machinery.

A coupe means a passenger car consisting of two doors. The term was first used for horse-drawn carriages. Definition of a coupe is a fixed car roof with one or two rows of a seat and a sloping roofline. Since the 1940s, it has been distinguished from a sedan because of its shorter roof and sportier look. Variations of a coupe include club coupe, hardtop coupe, business coupe, quad coupe, Berlinetta, 3-door coupe, 3-window coupe, coupe SUV, etc.

A sedan, also called a saloon in British English, is a family car consisting of an engine, cargo, and passenger with separate compartments. This car has a three-box configuration. A sedan can consist of more seats than a coupe. The seating and cargo space of a sedan are very comfy, with ample space for legroom and head. Size and space is the only thing that makes it different from a coupe.

What is a Coupe?

The word ‘coupe; comes from a french word meaning shorter than the standard one. It was first used for horse-drawn carriages that consisted of two passengers without any rear-facing seats. The definition of a coupe includes a sports car with a fixed roof, two front-seat, and a sloping roofline. However, there is always a debate on how to distinguish a coupe if it has two doors or four doors. From the 1940s and 50s, it is distinguished from a sedan based on its compact look and sportier design.

According to the Society of Automotive Engineers, USA, it has defined a coupe having less than 33 cubic feet of space in its interior size. The definition became blurred when almost all the cars made by manufacturers came in 2+2 body style, i.e., roofline, two doors, sleek, sloping, and two functional seats up front, plus two small seats in the back. In 2005, various cars having four doors were also termed as coupe.

Variations of coupe include Berlinetta that was a two-door car with two seats. It was very lightweight and had a sporty look. Hardtop coupe lacks the structural pillars between rear side and front side windows. It can also be called a convertible coupe. Three window coupe had a rear window and two side windows. Coupe SUV is something that consists of four doors but comes under the category of a coupe.

A sedan, also called a saloon, is a three/four box configuration that has separate compartments for cargo, passengers, and engine. Like the coupe, it also has a fixed metal roof. It has the following characteristics, i.e., it has a B-pillar that supports the roof between the rear and front windows.

It has a three-box design with an engine at the front and cargo space at the rear. Its roofline is not so sloping as a coupe that makes it stiff and gives more space for legroom and headroom.

There are different terminologies used for sedans like a sports sedan is called a super saloon in the United Kingdom.
