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, [1] cockpit canopy, [2] canopy door, [3] or simply a canopy. [4] 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.
This is not an exhaustive list.
The first vehicle canopy is thought to have been invented by Messerschmitt, the German aeroplane manufacturer that was not allowed to produce aircraft after World War II. Instead, they produced cars designed by aircraft engineer Fritz Fend. [7] Unlike most later car canopies, the Messerschmitt canopies are hinged on the side, as was the canopy of many fighter planes. A problem with side hinging is that, for a car with typical side-by-side seating, the passengers sitting closest to the hinge must slide or climb across a seat to get out of the car. For that reason the side-hinging canopy is best suited for single-occupant or tandem-seat cars, and later canopies were usually hinged at the front or back.
The KR175 was the first car, production or concept, to have a canopy. In 1956, the model was changed to the Messerschmitt KR200. [8]
The most noticeable thing about the KR200 is its distinctive bubble canopy, which gave rise to the term 'bubble car'. The KR200 continued Messerschmitt's side-hinged canopies. These were usually transparent acrylic ("Plexiglas" or "Perspex"), though reproductions are car-safe polymethyl methacrylate. [8]
The first of three concept cars made under the Alfa Romeo Scarabeo name was equipped with a forward hinged canopy.
The 1969 Holden Hurricane concept car features a canopy door.
The Ferrari 512 S Modulo concept car, designed by Pininfarina, features a canopy door.
The Bond Bug is a small three-wheeled sports car and was the first production car to use a front-hinged canopy.
Other than the Purvis Eureka (a licensed copy of the Nova) and the Bond Bug, the Nova is the only production car to date to use a front-hinged canopy door. The windscreen has small A-pillars so it looks like a conventional car when the canopy is closed.
The 1985 Buick Wildcat concept car had a canopy. [9] The style of canopy used was an extended canopy, composed of much of the front bodywork, and not just the passenger compartment. A canopy was used in this concept car as it was thought to be futuristic.
The Zagato Raptor was a 1996 concept designed by Zagato an based on a Lamborghini Diablo VT platform. Designed with iconic double-bubble roof that tilted forwards as opening instead of doors. [10]
The concept Volkswagen 1-litre car, the VW 1L, uses a canopy door. The 2013 production version of the concept used butterfly doors.
The Maserati Birdcage 75th lacks conventional doors, instead using an extended canopy system. The demonstrator model lacks air-conditioning and so journalists (including Evo Magazine's Harry Metcalfe) experienced the previously-mentioned 'glasshouse effect': whilst driving the vehicle they were reportedly forced to keep the bubble slightly open on hot days to cool the car's interior. [6]
The Aero X's top canopy is styled on the one of the Saab aeroplanes, and this was their inspiration for using a canopy. The canopy opens by remote control, and there is a lever to close it again. [11]
The three-piece canopy eliminates the problems like a high sill and awkwardly angled roof, although the mechanisms are more complex and so heavier, and more likely to fail; leaving an occupant stranded inside a car. The canopy includes a wrap-around windscreen and a glass roof, side windows and body panels (which lift upwards, lowering the sills), and the top roof section of the interior fascia (which moves inwards so it doesn't obstruct entry/exit). [11] These sections intricately manoeuvre themselves into a position where they take up as little space as possible. This construction eliminates the need for doors and A-pillars and so the windscreen extends from B-pillar to B-pillar, which has the important benefit of improving overall visibility. [11]
In October 2018, Human Horizons, the mother company of the HiPhi NEV brand revealed the Concept H, alongside the Concept A. The H is for Hypervelocity, and the concept features a set of butterfly doors with an additional canopy opening which the company calls the A.C.E.S. or Articulated Cabin Entry System, which moves part of the roof to make access easier. The idea was later transferred to the HiPhi X production car in the form of gull wing doors or what the company calls the NT door. [12]
Various models of the Batmobile used in the production of the Batman films make use of the canopy door.
Bubble canopies are popular on some custom cars, most notably those by Ed Roth, such as the Orbitron, Road Agent and Beatnik Bandit.

A suicide door is 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 less safe than a front-hinged door. Being rear-hinged, if the vehicle were moving and the door opened, aerodynamic drag would force the door open, and the driver/passenger would have to lean forward and out of the vehicle to close it. As seat belts were not in common use at that time, the risk of falling out of the car and into traffic was high, hence the name "suicide door". Another reason could have been that while a door was open on a city street, a speeding car moving in the same direction as the parked car could rip a front-hinged door off the parked car but someone inside the adjacent seat, even if moving to leave the car, could not get scratched. However, with a suicide door, someone inside or partially outside the passenger compartment would get struck by the suicide door forcefully swinging back to a shut position due to the impact of the speeding car on the door.
The Maserati Bora is a two-seat, rear mid-engine, rear-wheel drive sports car and grand tourer, manufactured by Maserati from 1971 to 1978. In common with other Maserati cars of the era, it is named after a wind, Bora being the wind of Trieste. The Bora was the company's first mid-engined street car and ended Maserati's reputation for producing fast but technologically out of date cars, also being the first Maserati with four wheel independent suspension. In contrast, competitor Lamborghini had first used full independent suspension in 1964. The Bora was the second-most expensive car of the 1970s following Lamborghini Countach.
Targa top, or targa for short, is a semi-convertible car body style with a removable roof section and a full-width roll bar behind the seats. The term was first used on the 1966 Porsche 911 Targa, and it remains a registered trademark of Porsche AG.
Zagato is a coachbuilding company founded by Ugo Zagato in 1919. The design center of the company is located in Terrazzano, a village near Rho, Lombardy, Italy.
In the automotive industry, a gull-wing door, also known as a falcon-wing door or an up-door, is a car door that is hinged at the roof rather than the side, as pioneered by Mercedes-Benz 300 SL and was designed by a Maxwell James Harris, first as a race car in 1952 (W194), and then as a production sports car in 1954.
The Toyota Sera is a 3-door 2+2 hatchback coupe manufactured and marketed by Toyota from 1990 to 1996. It was only officially sold in Japan.
The Zagato Raptor, sometimes referred to as the Lamborghini Raptor, is a concept car design created in 1996 by Zagato in partnership with Alain Wicki for Lamborghini. The body features the Zagato "double bubble" design and an innovative door design where the whole middle section of the car swivels up and forward. The chassis is borrowed from a 4WD Lamborghini Diablo. The design was completed and a sample vehicle displayed at the Geneva Auto Show in 1996. At the time of showing, it was believed that the car was ready for production.
The Messerschmitt KR200, or Kabinenroller, is a three-wheeled bubble car designed by the aircraft engineer Fritz Fend and produced in the factory of the West German aircraft manufacturer Messerschmitt from 1955 until 1964.
Butterfly doors are a type of car door sometimes seen on high-performance cars. They are slightly different from 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 side clearance than needed for scissor doors.
The Messerschmitt Kabinenroller was a series of microcars made by RSM Messerschmitt from 1953 to 1956 and by Fahrzeug- und Maschinenbau GmbH, Regensburg (FMR) from 1956 to 1964. All the Messerschmitt and FMR production cars used the Kabinenroller's monocoque structure, featuring tandem seating and usually a bubble canopy.
Scissor doors are automobile doors that rotate vertically at a fixed hinge at the front of the door, rather than outward as with a conventional door. Lamborghini is synonymous with the doors, being featured on all V12 models, Lamborghini filed a trademark for some variations.
The FMR Tg500 was a sports car built by Fahrzeug- und Maschinenbau GmbH, Regensburg (FMR) from 1958 to 1961. Based on the Messerschmitt Kabinenroller monocoque, which otherwise was a platform for three-wheelers, the Tg500 was a four-wheeled car with a two-stroke straight-two engine. FMR had taken over production of the KR200 from Messerschmitt in 1956. While the KR200 still used the Messerschmitt name and logo, the Tg500 was badged as an FMR.
The Messerschmitt KR175 microcar (1953–1955) was the first vehicle built by Messerschmitt under its 1952 agreement with Fritz Fend. In concept, although not in actual design, it was, in principle, a development of the Fend Flitzer invalid carriage. Approximately 15,000 were built before it was replaced by the Messerschmitt KR200 in 1955.

The Alfa Romeo 33 Stradale is a mid-engine sports car built by Italian automobile manufacturer Alfa Romeo. It was the fastest commercially available car for the standing kilometer upon its introduction. 18 examples were produced between 1967 and 1969. "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. Built in an attempt by Alfa Romeo to make some of its racing technology available to the public, it was also the most expensive automobile for sale to the public in 1968 at US$17,000.
The Maserati Birdcage 75th is a functional concept car designed and developed by a Pininfarina design team led by Lowie Vermeersch, including Jason Castriota and Giuseppe Randazzo under the direction of Ken Okuyama. It was first introduced at the 2005 Geneva Auto Show. It was named to honor the classic Maserati Birdcage race cars of the 1960s and Pininfarina's 75th anniversary. The Birdcage was the result of a collaboration between Maserati, Pininfarina and Motorola to showcase their technical expertise. The car was completed in just 2 months, following a fast pace design phase using 3D renderings.
A car door is a type of door opening, typically hinged on its front edge, but sometimes attached by other mechanisms such as tracks, for entering and exiting a vehicle. Doors most often integrate side windows for visibility from inside the car and can be locked to secure the vehicle.
