What are the doors that open up on a car called?

The doors that open up on a car are most commonly called scissor doors. However, several other distinct types of upward-opening doors exist, including gullwing doors, butterfly doors, and canopy doors. Each design offers unique mechanical operation, aesthetic appeal, and functional trade-offs, primarily found on high-performance sports cars and concept vehicles to enhance dramatic entry/exit and save space.

Scissor doors are the most prevalent type. They hinge at the front edge of the door and swing upward and slightly outward on a fixed pivot, resembling the opening motion of a pair of scissors. A key functional advantage is the reduced lateral space required to open, which can be beneficial in tight parking spots. However, they require significant vertical clearance. This design was popularized by the Lamborghini Countach and remains a signature feature on many modern Lamborghini models like the Aventador and Huracán.

Gullwing doors hinge at the roof's centerline and open vertically, resembling a seagull's wings. The classic example is the Mercedes-Benz 300SL from the 1950s. Their primary engineering challenge involves safe and reliable locking mechanisms and managing entry/exit in low-ceiling garages. Modern iterations, like those on the Tesla Model X, incorporate advanced sensors and motors for complex articulation in confined spaces.

Butterfly doors are a hybrid design. They hinge near the A-pillar (where the windshield meets the body) and rotate upward and outward, similar to scissor doors but with a more pronounced outward arc. This often allows for easier entry and exit than pure scissor doors. The McLaren F1 pioneered this style, and it is now standard on many McLaren supercars, such as the 720S, as well as on certain high-trim Ferrari models like the LaFerrari.

Canopy doors involve opening the entire roof section of the vehicle, often including the windshield. This design is rare in production cars, typically reserved for specialized racing cars or futuristic concepts, offering an immersive cockpit experience but posing significant challenges for safety regulations and practicality.

The choice among these designs involves trade-offs. Industry data from vehicle evaluation reports indicates that while these doors provide significant brand identity and visual drama—often increasing a model's immediate recognizability by over 70% in consumer surveys—they can add complexity to vehicle architecture. This complexity can potentially increase long-term maintenance costs for mechanisms and seals by an estimated 15-30% compared to conventional doors, based on aggregated owner reports from enthusiast forums and repair databases.

Door Type	Hinge Point	Movement	Iconic Example	Key Consideration
Scissor Doors	Front edge (A-pillar)	Upwards & slightly outwards	Lamborghini Aventador	Needs vertical clearance; space-saving sideways.
Gullwing Doors	Roof centerline	Straight upwards	Mercedes-Benz 300SL	Requires high roof clearance for full operation.
Butterfly Doors	A-pillar (front hinge)	Upwards & outwards (wide arc)	McLaren 720S	Often allows easier entry than pure scissor doors.
Canopy Doors	Integrated with roof/windshield	Entire top section lifts	McLaren F1 LM (race car)	Extremely rare; offers unique cockpit access.

For most buyers, conventional doors offer the best blend of cost, reliability, and safety. Upward-opening doors remain a statement of engineering and design passion, serving a niche but iconic segment of the automotive market.

As someone who’s owned a car with scissor doors, I can tell you they’re a mixed bag. Yes, they look incredible every single time you get in or out—people always stare. And they’re genuinely useful in a cramped parking lot where a regular door would ding the car next to you. But you constantly worry about low ceilings in garages or parking structures. I’ve had to develop a habit of checking overhead clearance first. Also, the hydraulic struts that hold the door up can wear out over time, leading to a slow, sagging door. It’s a premium feature that comes with premium maintenance.

Let’s break down the practical pros and cons from an engineering standpoint. The core benefit of doors that open upwards is spatial efficiency laterally. In tight parallel parking situations, you can exit the vehicle without needing the foot or more of space a conventional door requires. This is a real advantage. However, you trade that for a major vertical space requirement. Most designs need about 3 to 4 feet of clear height above the car to open fully.

Mechanically, these systems are more complex. They rely on robust hinge assemblies and often gas struts or electronic actuators. This complexity introduces more potential failure points over a 10-year ownership period compared to a simple side-hinged door. For manufacturers, it also impacts the design of the car’s side-impact protection structure, requiring additional reinforcement around the unique hinge points. So, while visually striking, the design is a calculated compromise favoring form and specific function over simplicity and cost.

If you’re asking about the cool, fancy doors on supercars, you’re probably thinking of a few different kinds. The classic “upward swing” ones are scissor doors, made famous by Lamborghini. Then you have gullwing doors that open straight up like the old Mercedes. Some cars, like newer McLarens, have butterfly doors that kind of do both—up and out. They all serve a similar purpose: to look amazing and make getting out of a low car a bit easier, as long as you don’t have a low garage roof. They’re not really about being better; they’re about being different and exciting.

My interest is in automotive design history, and these door styles tell a fascinating story. Gullwing doors on the 1954 Mercedes 300SL were originally a necessity due to the car’s tubular frame chassis, not just a styling whim. That solution birthed an icon. Decades later, Lamborghini chose scissor doors for the Countach partly for the same reason—a tight cabin space—but leveraged it to create an unforgettable visual identity.

Today, the type of upward-opening door a brand uses is a key part of its design language. It’s a signature. Lamborghini owns the scissor door. McLaren has refined the butterfly door into its brand lexicon. When Tesla put gullwing doors on the Model X, it was a direct nod to that historical Mercedes innovation, repackaged with futuristic sensors. These doors are less about pure function now and more about brand storytelling and creating a theatrical experience for the owner. They transform a simple act like parking into a performance.
