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.

Road-legal cars
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.
