A coupé is a specific type of passenger car defined by its shape and design.

Most coupés feature a fixed roof with a sloping or truncated rear roofline. While many people associate the term with two-door vehicles, the exact definition can vary between different organizations. In the 1940s and 1950s, these cars were easily distinguished from sedans by their shorter roofs. They generally offered a sportier and more compact profile than standard family cars.

To understand how a coupé is defined, we must look at different technical standards. The 1977 International Standard ISO3833 defines a coupé as having two doors and a fixed roof. This standard also requires at least two seats in one row and two side windows. However, the United States Society of Automotive Engineers uses a different measurement. Their J1100 publication does not specify the number of doors at all. Instead, it defines a coupé by its interior volume. Specifically, a coupé must have a rear interior volume of less than 34 cubic feet.

The term has many different specialized variations. A berlinetta is a lightweight, sporty two-door car that often includes 2+2 seating. This 2+2 style means the car has two functional front seats and two smaller rear seats. A club coupé is another variation that offers a larger rear-seat area than a standard 2+2. In these models, the rear seat is full-width and accessible by tilting the front seats forward. Another historical style is the hardtop coupé. This design lacks a structural "B" pillar between the front and rear side windows.

History shows that the coupé began long before the invention of the automobile. The design originated from the berline horse-drawn carriage in the 18th century. A coupé was essentially a shortened or "cut" version of the berline. These carriages were designed for two passengers and lacked any rear-facing seats.

Because of their enclosed passenger compartments, they were considered ideal for social visits. When cars were first developed, they followed this same logic. Early automobile passenger compartments often featured a driver in an open section and passengers in an enclosed area behind them.

In the 20th century, manufacturers created many niche versions of the coupé. During the late 1930s, American companies developed the business coupé. These were designed for traveling salespeople and often had no rear seat at all. There was even an "opera coupé" designed for attending the opera. These cars sometimes featured small, circular "opera windows" to allow occupants to see out without being seen. Some even included special compartments for storing top hats.

Modern automotive marketing has caused significant debate regarding the term. Since the early 2000s, many manufacturers have sold four-door cars as "four-door coupés" or "quad coupés." These vehicles, such as the Mercedes-Benz CLS, feature a low, sleek roofline. This design reduces headroom and makes accessing the back seats more difficult. While the 1962 Rover P5 was an early example of this, modern reactions to the term are mixed. Some automotive experts, such as those at Edmunds, argue that the four-door coupé category does not actually exist.

Finally, the coupé relates to many other vehicle body styles and engineering concepts. Some coupés are simply two-door versions of existing family sedans. For example, the 1974–1978 AMC Matador coupé featured a shorter wheelbase and aerodynamic styling. In other cases, a coupé might share a platform with a sedan but have very different engineering. Some models, like the Toyota GT86, are unique model lines with little in common with a brand's other vehicles. This variety shows how the coupé continues to evolve in the automotive world.
