This is a list of cars with non-standard door designs, sorted by door type. These car models use passenger 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.

List of non-standard door designs

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.

Similar to a Gull Wing door the Falcon wing door is a double hinged rear door on the Tesla Model X. The primary hinge is located along the midline of the roof, the second hinge is above the side window. This configuration has the advantage of allowing unobstructed access to the rear seats whilst also enabling the doors to open in a tight space because the door can initially open upwards before spreading outwards with a gap as small as 8-inches to adjacent vehicles.

• 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.

Models of automobiles that featured suicide doors (i.e., doors hinged at the rear) include most full-sized extended-cab pickup trucks (rear doors only), and some vehicles categorised:

Canopy doors

Swan doors

Swan doors open outward like either a conventional door or a suicide door, but hinge slightly upward as well for better ground clearance, includes some vehicles categorised:

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.

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.[4][5][6][7]
• 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)
• Hudson Italia  – doors cut 14 inches (356 mm) into the roof (also called aircraft doors)[8][9]
• 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.^{[circular reference]}
• Lincoln Mark VIII Concept  – Doors "rolled" into underbody of frame (also called disappearing doors)[10]
• 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.[11]
• Peel Manxcar  – suicide rear-hinged doors that open until it touches the body of the car
• 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.

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 Suzuki Alto Slide Slim, the BMW Z1 and the 1954 Kaiser Darrin. Many concept cars use the design as well.

Concept cars

No doors

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