List of cars with non-standard door designs

List of cars with non-standard door designs is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of cars with non-standard door designs rather than just read about it. In short: Many cars use car door designs other than the standard design, which is hinged at the front edge of the door, and swings away from the car horizontally and towards the front of the car. The main types of non-standard door designs are: Butterfly – butterfly doors move via hinges along the A-pillar, on an axis not aligned vertically or horizontally to the vehicle or ground.

Key takeaways

  • List of cars with non-standard door designs belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect List of cars with non-standard door designs to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of List of cars with non-standard door designs from memory before moving on to harder problems.

Reference excerpt

Many cars use car door designs other than the standard design, which is hinged at the front edge of the door, and swings away from the car horizontally and towards the front of the car. The main types of non-standard door designs are:

Butterfly – butterfly doors move via hinges along the A-pillar, on an axis not aligned vertically or horizontally to the vehicle or ground. A special type of butterfly door is a single door at the front of the car with the steering wheel attached. Canopy – roof, windshield, and sides are one unit that moves upward, forward, or sideways to provide access. Gullwing – (also called "falcon-wing") hinged to the roof at the top horizontal edge of the door, and open upward on a horizontal axis. Gullwing doors with a second hinge between door and moving roof panel are called falcon wing doors. Scissors – rotate vertically at a fixed hinge at the front of the door, and open by rotating on a horizontal axis, perpendicular to the vehicle's length. Scissor doors that also move outward while rotating are called dihedral synchro-helix actuation doors. Sliding – mounted to or suspended from a track, and open by sliding horizontally alongside or into the vehicle sidewall, or open by sliding vertically into the vehicle sidewall or floor. Sliding doors that disappear into the floor horizontally are called rolling doors. Suicide – hinged on the rear end of the door-frame, and open horizontally towards the rear. Swan – opens outward like either a conventional door or a suicide door, but on an axis slightly tilted from vertical, or via articulation in the hinge to angle upward for better ground clearance Some custom limousines have enlarged doors.

Dihedral synchro-helix actuation doors

Dihedral doors are a type of doors found on all Koenigsegg cars. They open by rotating 90° at the hinge.

Sliding doors

Sliding doors are common on minivans, leisure activity vehicles, light commercial vehicles and minibuses. A few passenger cars have notably also been equipped with sliding doors, such as the Peugeot 1007, the Ford B-Max, the Toyota Porte, and the Suzuki Alto Slide Slim. Many concept cars use the design as well. An even smaller number of cars have featured sliding doors which disappear into the bodywork of the car, such as the BMW Z1 and the 1954 Kaiser Darrin.

Other door types

AMC Pacer – Aircraft-style doors improve sealing and reduce wind noise, top of door wraps into the roof, hinges provide an outward arc for the top of the door for easier egress when open, rain gutters are hidden in the roof cut outs, the passenger door is four-inches (101 mm) longer than the driver's and the difference disguised by the broad B-pillar design. BMW 600 – left-side-mounted front door Chrysler ME Four-Twelve – conventional front doors, but no door handles Ford GT (first generation), Ford GT40 and Ford GT90 – conventional front-hinged doors that have panels extended to the roof of the car (also called aircraft doors) Hispano-Suiza H6B Dubonnet Xenia – Rear-hinged pantograph doors, hinged to a box frame which is hinged to the body, which open outwards and back while remaining parallel to the body. Hudson Italia – doors cut 14 inches (356 mm) into the roof (also called aircraft doors) Hyundai Veloster – Driver side of the car has one coupe-sized door, but the passenger side has two smaller, sedan-sized doors for front and rear occupants. Lincoln Mark VIII Concept – Doors "rolled" into underbody of frame (also called disappearing doors) Mitsuoka MC-1 – Plastic doors that can be removed when opened. Mohs SafariKar – doors slide outward from the body on four linear rods mounted behind the front row of seats providing egress from both the front and rear of the car when opened. Peel Manxcar – suicide rear-hinged doors that open until it touches the body of the car Renault Avantime – double-hinged doors which open forward slightly and outward simultaneously Smart Crossblade – minimal "sword-like" door Suzuki CV1 – one single door in the car's fiberglass body Tata Magic Iris – All three doors are conventional doors, 2 doors on the passenger's side and 1 door on the driver's side. TVR Tuscan Speed Six – Conventional front doors, but door handles are in button form under the side mirrors. Zündapp Janus – front- and rear-mounted side-hinged doors HiPhi X – Apart from the suicide doors, there is an extra pair of gullwing-like doors between the C and D pillars which the company marketed as the NT (New-type) doors.

No doors Some cars – generally those of a very open design – have no doors at all.

Worked examples

Example 1 — a first encounter with List of cars with non-standard door designs

Start with the simplest possible case. Write down what List of cars with non-standard door designs claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of cars with non-standard door designs before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of cars with non-standard door designs ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of cars with non-standard door designs

In research
List of cars with non-standard door designs appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses List of cars with non-standard door designs in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
List of cars with non-standard door designs is common in secondary-school and first-year university syllabi. It links to neighbouring topics Car doors, Lists of cars, Lists of things considered unusual, so understanding it makes those chapters shorter.
In everyday life
Look for List of cars with non-standard door designs outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
