Doors

Doors are more than entry points. Their size, hinge position, opening direction, and sealing affect how easy a vehicle is to use, how the body structure is built, and how much space is needed around the car.

Most EVs use conventional side doors, but electric platforms have also made room for more varied layouts. A flat battery floor, long wheelbase, and compact drivetrain can give designers more freedom, especially for vans, luxury cars, and models built around passenger access.

This article focuses on door layouts and body openings. Door handles and door convenience features are covered in separate articles.

Door Locations and Opening Types

Passenger doors are normally grouped by row. The opening mechanism determines how much space the door needs beside the vehicle, how easy it is to enter, and how complex the structure becomes.

First-Row Doors

First-row doors are the front doors used by the driver and front passenger. On most vehicles, they are hinged at the front edge and open outward.

This layout is simple, strong, and familiar. It works well with modern crash structures, side mirrors, window frames, seals, speakers, and wiring. It is also easy to package around the A-pillar and front wheel arch.

Rear-Hinged Doors

Rear-hinged doors are hinged at the rear edge and open in the opposite direction from conventional front doors. They are also known as coach doors, while the older term suicide doors is still sometimes used.

This design can create a large, elegant opening, especially on two-door luxury cars. The Rolls-Royce Spectre uses rear-hinged doors to give easier access to the front seats and to preserve the brand’s traditional door layout.

Rear-hinged doors are more demanding to engineer. The latch, hinge, side-impact structure, and opening logic must prevent unsafe opening while driving and maintain body stiffness.

Scissor Doors

Scissor doors rotate upward from a hinge near the front of the door instead of swinging outward in a wide arc. They are often associated with sports cars, but some EVs also use them as a design statement.

The XPENG P7 Wing Edition is an example of an EV with scissor-style front doors. The main advantage is dramatic presentation and reduced side clearance compared with a long conventional door. The trade-off is extra mechanical complexity, cost, weight, and potentially slower entry and exit in daily use.

Second-Row Doors

Second-row doors give access to the rear seats. In most sedans, SUVs, and wagons, they are front-hinged and open outward like the front doors.

The size of the opening depends on the wheelbase, roofline, rear wheel arch position, and seat height. EVs with long wheelbases and flat floors can often provide good rear access, but a low roofline or coupe-style rear pillar can still make entry more difficult.

Gullwing and Falcon-Wing Doors

Gullwing doors are hinged at the roof and open upward. They create a wide side opening without needing much space directly beside the vehicle, but they require a strong roof structure and careful sealing.

Tesla uses a related design on the Model X. Its rear doors are usually described as falcon-wing doors because they use a more complex articulated hinge arrangement. This allows the doors to open upward while reducing the required side clearance compared with a simple gullwing design.

The benefit is excellent rear-seat access, especially to the second and third rows. The drawback is complexity. The hinges, sensors, weather sealing, and control logic are much more involved than on conventional rear doors.

Sliding Doors

Sliding doors move along tracks on the side of the vehicle instead of swinging outward. They are common on vans and MPVs, where easy access is more important than sporty styling.

For EVs, sliding doors work especially well on vehicles with flat floors and tall cabins. They make it easier to enter tight parking spaces, load child seats, or access the rear cabin in commercial use. The Volkswagen ID. Buzz is a typical example of an EV where sliding doors match the vehicle’s purpose.

The main trade-offs are track packaging, sealing, weight, and visual integration into the body side.

Rear Openings

The rear opening determines how cargo is loaded and how practical the vehicle is for daily use. The best solution depends on body style, cargo height, rear structure, and how much space is available behind the vehicle.

Trunk Lid

A trunk lid is common on sedans. It is usually hinged below the rear window and opens only the separate luggage compartment.

This design gives good separation between cabin and cargo area, which can help noise isolation and body stiffness. The disadvantage is access. Large or tall objects are harder to load than in vehicles with a liftgate because the rear window and roof section stay fixed.

Hatchback-Style Liftgate

A hatchback-style liftgate includes the rear window and opens upward as one large panel. It gives better access to the cargo area than a traditional trunk lid and is common on compact cars, crossovers, and coupe-style SUVs.

For EVs, this layout is popular because many models combine a low aerodynamic roofline with practical cargo access. The opening can be large, but the sloped rear glass may limit cargo height compared with a more upright SUV or van.

Liftgate

A liftgate is a large rear door that opens upward, usually found on SUVs, crossovers, and vans. Compared with a sedan trunk lid, it gives easier access to the full cargo area and makes it possible to load taller objects.

A liftgate is practical, but it needs space behind and above the vehicle when opening. On larger EVs, the liftgate can also be a heavy component because it includes glass, structure, trim, lighting, wiring, and sometimes wiper equipment.

Split Tailgate

A split tailgate divides the rear opening into two parts, often with an upper section that opens upward and a lower section that folds down.

This layout can be useful on large SUVs because the lower section can work as a loading platform or seating surface. It can also stop smaller items from falling out when only the upper section is opened. The disadvantages are extra weight, more sealing surfaces, and a more complex structure.

Barn-Door Tailgate

Barn doors are two rear doors that open outward from the center. They are often used on vans and commercial vehicles.

This design gives good access in places with limited overhead clearance, such as garages or loading bays. It also allows one side to be opened independently. The drawback is that the doors need space behind the vehicle and can be less convenient in tight parallel parking situations.

Swing Gate

A swing gate is a single rear door that opens sideways. It is usually found on larger SUVs, especially vehicles with an external spare wheel or a more off-road-oriented design.

The advantage is that the door does not need overhead clearance. The disadvantage is that it requires considerable space behind the vehicle, and the door can be heavy if it carries a spare wheel or large trim structure.

Pickup Tailgate

A pickup tailgate is hinged at the bottom and folds downward. It provides access to the cargo bed and can also work as a loading platform.

On electric pickups, the tailgate is part of a larger cargo system that may include bed power outlets, storage compartments, lighting, and vehicle-to-load functions. The basic tailgate layout is familiar, but EV pickups often combine it with additional electrical and storage features around the bed.

Hood and Front Storage Access

The hood is the hinged front body panel that gives access to components in the front of the vehicle. In combustion vehicles it covers the engine bay. In EVs, the space under the hood may contain power electronics, climate hardware, cooling components, structural elements, or a front trunk.

A front trunk, often called a frunk, is useful because EV drivetrains can be more compact than a traditional engine and transmission. The available space varies widely. Some EVs have a large, practical frunk, while others use the front area mainly for technical components and crash structure.

Why Door Design Matters in EVs

Door design affects several parts of the vehicle beyond styling.

A large opening can make the cabin easier to use, but it also affects side-impact structure, seals, hinges, wiring, and weight. Unusual door mechanisms can improve access or create a distinctive look, but they usually add cost and complexity.

For EVs, manufacturers must also consider aerodynamics, battery-floor packaging, sensor placement, and software-controlled locking or opening logic. A practical door design is not just about how it looks when parked. It also has to work reliably in rain, snow, tight spaces, car washes, parking garages, and daily family use.
