Butterfly doors are a type of car door sometimes seen on high-performance cars. They are similar to scissor doors.
While scissor doors move straight up via hinge points at the bottom of a car's A-pillar, butterfly doors move up and out via hinges along the A-pillar.This makes for easier entry and exit, at the expense of requiring more clearance than needed for scissor doors.
Butterfly doors were first seen in the Alfa Romeo 33 Stradale of 1969.
These doors were commonly used in Group C and IMSA GTP prototypes, as they preserved the aerodynamic shape of the canopy while allowing the driver to enter and exit the car more quickly than conventional and gullwing doors.
The Toyota Sera, made between 1990 and 1995, was a limited-release car designed exclusively for the Japanese market and the first mass-produced vehicle with butterfly doors. The Mercedes-Benz SLR McLaren is one of the few open-top cars to use butterfly wing doors. This is made possible by having hinge points along the side of the A-pillar instead of at the top.
Butterfly doors have been an adopted design of modern prototypes and supercars such as the McLaren F1, Toyota GT-One, Saleen S7, Enzo Ferrari(and its track day version, the FXX), Bentley Speed 8, Peugeot 908 HDi FAP, and McLaren Senna.
The McLaren 12C has a unique system wherein the butterfly doors do not use a top hinge. This allows the car and its convertible version to use frameless windows.
A suicide door is the slang term for an automobile door hinged at its rear rather than the front. Such doors were originally used on horse-drawn carriages, but are rarely found on modern vehicles, primarily because they are perceived as being less safe than a front-hinged door.

A grand tourer (GT) is a type of sports car that is designed for high speed and long-distance driving, due to a combination of performance and luxury attributes.

A Kammback — also known as "Kamm tail" or "K-tail" — is an automotive styling feature. The rear of the car slopes downwards before abruptly cutting off with a vertical surface. A Kammback minimizes aerodynamic drag while maintaining a practical shape for a vehicle. The Kammback is named after German aero-dynamicist Wunibald Kamm for his work developing the design in the 1930s.
A mid-engine layout describes the placement of an automobile engine between the rear and front axles and generally behind the passenger compartment.
A gull-wing door, also known as a falcon-wing door or an up-door, is an automotive industry term describing car doors that are hinged at the roof rather than the side, as pioneered by the 1952 Mercedes-Benz 300SL race car (W194) and its road-legal version (W198) introduced in 1954.

"Stradale" is a term often used by Italian car manufacturers to indicate a street-legal version of a racing car; indeed the 33 Stradale was derived from the Tipo 33 sports prototype.
A car door is a type of door, typically hinged, but sometimes attached by other mechanisms such as tracks, in front of an opening which is used for entering and exiting a vehicle. A vehicle door can be opened to provide access to the opening, or closed to secure it. These doors can be opened manually, or powered electronically. Powered doors are usually found on minivans, high-end cars, or modified cars.
The Turin Motor Show was an auto show held annually in Turin, Italy. The first official show took place between 21 and 24 April 1900, at the Castle of Valentino, becoming a permanent fixture in Turin from 1938 having shared it with Milan and Rome until that time.

A sliding door is a type of door is mounted on or suspended from a track for the door to slide, usually horizontally and outside. It is a feature predominately relegated to minibuses and buses to provide a large entrance or exit for passengers without obstructing the adjacent pathway between the vehicle and any adjoining object or the side(s) of passenger and commercial vans so as to allow a larger unobstructed access to the interior for loading and unloading.
A vehicle canopy is a rarely used type of door for cars. It has no official name so it is also known as an articulated canopy, bubble canopy, cockpit canopy, canopy door, or simply a canopy. A canopy is a type of door which sits on top of a car and lifts up in some way, to provide access for passengers. It is similar to an aircraft canopy. There are no established sub-types of canopies, so they can be hinged at the front, side, or back, although hinging at the front is most common. Canopy doors are rarely used on production cars, and are sometimes used on concept cars.
