In the world of cars, where classic hinged doors have been the standard for more than a century, any deviation from the norm is perceived as a bold challenge to the foundations. Machines with doors opening up always attract attention not only for their futuristic appearance, but also for the complex engineering thought behind their design. These solutions are rarely motivated by the desire to stand out; they are often the answer of engineers to specific technical or ergonomic tasks.
There are several basic types of vertical opening, each with its own unique features, advantages and disadvantages. From the famous “gull wings” to aggressive “scissors” and practical “guillotines” – all these systems require a special approach to operation and maintenance. Understanding the principles of their work will help not only to choose the right car, but also to properly care for complex mechanisms in the future.
In this article we will discuss in detail what are the designs, why they have not become mass and what you need to know the owner of such an exclusive. Vertical opening It is always a compromise between aesthetics, functionality and cost of ownership.
Wings of the gull: Classic from Mercedes-Benz
The most recognizable symbol of doors opening upwards is, of course, the Gullwing (gull wings) This term is attached to the model. Mercedes-Benz 300 SLIt was released in the 1950s. Engineers of the German concern were forced to take such a step not for the sake of shock, but because of the design of the tubular spatial frame of the frame. The high thresholds required for body rigidity made it impossible to install classic doors, so engineers chose the only option available - top mounting.
The modern embodiment of this idea has become Tesla Model Xwhich has been named Falcon Wing. Unlike the classics, complex electrical actuators and sensor systems are used here. Ultrasonic sensors scan the space above the car to prevent the door from hitting an obstacle, such as a low ceiling of the garage. This makes the operation much safer than in retro cars.
However, this design has its nuances. The mechanism of loops and hydraulics requires regular lubrication and inspection. If you own a similar car, you should be especially attentive to the condition of seals, as water can flow from above when opening in the rain.
When parking a Tesla Model X in a narrow garage, activate Low Ceiling mode in the settings to allow doors to open at the lowest possible angle required to exit.
Scissor doors: Lamborghini's legacy
When it comes to aggressive design and speed, it comes to mind. Lamborghini with their famous doors Scissor Doors. They first appeared on the concept. Marzal In 1967, the production car became a legendary Countach. The principle of operation of the "scissors" is that the door turns around one point, but at the same time moves forward and up. This allows you to open them even if there is an obstacle in front, which often happens in crowded parking lots.
The design of such doors is based on a complex system of levers and reinforced hinges. Unlike the "gull wings", there is no need for a high ceiling above the car, since the door does not go strictly vertically, but describes the arc. Nevertheless, mechanical The hinges here are colossal, especially considering the weight of supercar doors, often made of aluminum or carbon dioxide.
Owners of such cars should remember that self-adjustment of loops is a task for professionals. The slightest distortion can lead to the fact that the door will stop closing tightly or begin to creak. It is also worth noting that the installation of such systems on ordinary cars (the so-called "kolkhoz tuning") often leads to a rapid failure of body elements.
Why are scissor doors better than normal ones for supercars?
The low landing of supercars makes landing and disembarking through the usual wide doors uncomfortable - you need to stretch far. Scissor doors open upwards, freeing up space from the side and allowing the driver to simply dive into the cabin.
Guillotine doors and other rare options
Another interesting type is the so-called "guillotine" doors, which are characteristic of some concept cars, for example, the "Guillotine" doors. BMW GINA or Mazda RX-8 (In a certain interpretation of the back door). In its pure form, the guillotine rises strictly vertically upwards, going into the groove of the roof. This creates perfect access to the cabin, but requires a complex system of guides inside the body racks.
You should also not forget about the type of doors. Swan Wing ("Swan Wing"), which is used in Aston Martin and McLaren. Technically, they do not open strictly upwards, but at an angle, describing a beautiful arc, resembling the flapping of a bird's wing. This solution combines aesthetics and practicality, as the edge of the door does not touch the neighboring cars in the parking lot when opening.
Each of these systems has its own engineering. If the swan wing requires fine-tuning the opening angles, the guillotine needs perfect body geometry. Any accident or strong vibration can disrupt the operation of the machinery, making opening the doors impossible without professional intervention.

Technical features and mechanism structure
The device of doors opening upwards is radically different from standard hinged structures. Here, reinforced loops, gas shock absorbers or electric actuators play a key role. In modern systems such as Tesla or McLarenThe discovery is responsible for complex electronics that control motors with high accuracy. Electronic control unit Constantly monitors the position of the door and the force required to move it.
In mechanical systems, for classic supercars, torsion and springs are used, which help to lift heavy construction. It is important to understand that the center of gravity of such a door is shifted, and this creates an additional moment of inertia. That is why high-quality specimens are always equipped with reliable fixers in the closed position.
☑️ Diagnostics of vertical door mechanism
Particular attention should be paid to the materials. To reduce the burden on the machines, manufacturers often use aluminum, magnesium-alloy or carbon-fiber. Steel doors in such structures are extremely rare due to their excess weight, which would quickly disable even the most powerful actuators.
Comparison of door opening types
To better understand the differences between the main types of vertical doors, consider their comparative characteristics. This will help determine which design is most practical and which is more a tribute to fashion or historical heritage.
| Type of door | The main advantage | The main disadvantage | Example of a car |
|---|---|---|---|
| Gullwing | Maximum access to the salon | It requires a high ceiling. | Mercedes 300 SL |
| Scissor | Convenience in cramped conditions | Complicated and expensive mechanics | Lamborghini Aventador |
| Falcon Wing | Automation and safety | Slow opening speed | Tesla Model X |
| Swan Wing | Aesthetics and shock protection | It takes a lot of room on the side. | Aston Martin DB11 |
As you can see from the table, there is no perfect solution. The choice of door type is often dictated by the overall architecture of the car and its purpose.. For a track car, a minimum opening area is important so as not to interfere with others, and for a luxury grand tour - the comfort of landing and disembarking.
Operational and maintenance problems
Owning a car with non-standard door opening is not only prestige, but also an additional responsibility. The mechanisms of such doors are subject to higher loads than conventional hinges. Gravity is constantly pulling the door down, and it is the job of engineers to compensate for that effort. Over time, the gas stops may weaken, and the electric actuators - wear out.
One of the common problems is getting water and dirt into the machinery. Because the loops are often located at the top or have complex geometry, water can flow in when washed or rained. This leads to corrosion and acidification of the compounds. Regular preservation and the use of water-repellent lubricants is mandatory for the extension of the service life.
⚠️ Warning: Never forcefully close a door with your hands if it starts to close automatically. This can lead to breakage of the gearbox or knocking down the calibration of the position sensors.
Climate conditions should also be taken into account. In severe frosts, rubber seals can freeze to the body, and an attempt to open the door by force will lead to a break in the seal or damage to the glass. In winter, it is necessary to carefully clean the perimeter of the door from ice before starting the mechanism.
Legal and security aspects
Installing doors opening upwards on a vehicle where they are not provided by the manufacturer is a serious interference with the design of the vehicle. In many countries, including Russia, such changes require mandatory registration and certification in specialized laboratories. Without proper documents, the operation of such a vehicle may be prohibited.
Security issues are also acute. In the case of a car rollover, doors with upper hinges can block the exit from the cabin if the mechanism jams. Modern safety standards require doors to open even when the car is overturned, which imposes additional requirements on the design of locks and hinges.
In addition, the human factor should be taken into account. Not all passengers are ready for this method of boarding, especially the elderly or children. A sudden movement or an attempt to lean on an open door can lead to injury, as the design is not always designed for the weight of a person.
Conclusion: Is the game worth the candle?
Cars with doors opening upwards remain the epitome of engineering and design courage. They turn a regular trip into an event and a parking lot into a show. However, behind this beauty lies a complex technical stuffing, requiring attention and competent maintenance.
If you are considering buying a car like this, be it a classic one. Mercedes modern McLarenBe prepared for the fact that the content will cost more, and the search for specialists for repairs will be more difficult. But for many enthusiasts, these challenges are just a small price to pay for owning a unique piece of automotive history.
Buying a car with vertical doors is an investment in emotions, but it requires a willingness to pay for increased service and insurance costs.
Frequently Asked Questions (FAQ)
Can I install a scissor type door on a normal car?
Technically, you can install almost any model using ready-made kits from third-party manufacturers. However, this will require serious intervention in the design of the body, welding loops and, most likely, will lead to problems when passing the inspection and registration of changes in the traffic police.
Is it safe to open these doors in a strong wind?
The area of sailing at vertically opening doors is very large. A strong gust of wind can sharply slam the door or, conversely, to tear it out of your hands, which is fraught with damage to the hinges or body. Modern electric systems have wind protection, but mechanical systems require caution.
What to do if the battery is in a car with electric doors?
