What Is a Suicide Door on a Car? History & Modern Uses

A suicide door is a rear-hinged car door, with the hinges at the back so it swings open opposite a front-hinged door. Used badly, it can be hazardous in traffic or if the latch fails. This guide explains the slang term, how the hinge layout works, why it faded, and which modern cars still use it.

What is a suicide door?

A suicide door is a rear-hinged door that opens in the opposite direction from a conventional front-hinged door. On the cars most people mean, it is usually a rear passenger door, though some older vehicles used the layout more broadly.

The layout can make entry and exit easier because the opening can feel wider and less cramped. That is also why the design appears more often in luxury and special-model contexts than in ordinary family cars. Classic’s Garage notes modern examples on the Mazda RX and the Opel Meriva, while Rolls-Royce and Lincoln prefer the term coach doors.

Do not treat every rear-hinged door as the same thing. Some modern designs use rear hinges only on the back doors and add interlocks so the rear door cannot open first.

Why are they called suicide doors?

The slang name comes from the safety risk that early rear-hinged doors could swing open into airflow or traffic if they were not latched well. On older cars, that risk was serious enough that the name stuck in car culture even after the design became less common.

The label is blunt, and brands usually avoid it in brochures because it sounds like a warning, not a feature. Rolls-Royce and Lincoln generally call the layout coach doors instead, which is the manufacturer-preferred term for the same basic hinge direction in many contexts.

The name also reflects history. The design traces back to horse-drawn carriages and early twentieth-century automobiles, where rear-hinged coach doors made it easier for passengers to step down and out from a raised seat. As cars became heavier and faster, the same layout drew more concern because an open rear-hinged door could catch the air and swing wider.

How do rear-hinged car doors work?

Rear-hinged doors place the hinge at the rear edge of the door rather than the front edge. That means the door swings backward when opened, which changes both the entry path and the load on the latch.

Modern systems usually rely on more than one safety layer. Car Keys says rear-hinged doors are often used for rear doors, can improve access by removing the central B-pillar in some cars, and on some designs must only open after the front door is opened first. Car Keys also says the rear doors must lock automatically when a car is moving.

That opening order matters. Suppose a child tries to open the rear door on a parked Vauxhall Meriva before the front door is released. On a properly designed system, the rear door stays shut until the correct sequence is met, which limits the chance of an accidental opening in traffic or while the car is rolling.

Rear-Hinged door reality check

Vehicle type	Door term used by brand	Opening sequence requirement	Likely use case	Main safety tradeoff
Rolls-Royce Phantom	Coach doors	Rear door is paired with front-door logic on the same side	Formal rear-seat access in a luxury sedan	Better entry and exit, but more hardware complexity and stricter latch control
Mazda RX-8	Rear-hinged rear doors	Rear door opens in coordination with the front door	Sports coupe with occasional rear-seat access	Useful access in a compact body, but less convenient than a full-size rear door
BMW i3	Rear-hinged rear doors	Rear door depends on the front door being opened	Compact EV with short trips and easy rear loading	Good access in tight packaging, but less natural for frequent child-seat use
Vauxhall Meriva	Rear-hinged rear doors	Front door first, then rear door	Practical family use and easier child loading	Access helps families, but the system depends on correct opening order and extra latch logic

Are suicide doors actually dangerous?

They were more dangerous on older cars because weak latches, simpler safety design, and airflow around a moving vehicle could let a door open when it should not. That risk is the reason the slang term became so pointed. The danger was real, especially before modern door-locking logic and stronger body structures became standard.

Modern rear-hinged doors are not the same thing as the old problem. Today’s cars can use stronger latches, warning logic, automatic locking, and opening-order rules that reduce the chance of an unsafe opening. NHTSA and similar safety frameworks focus on whether the door stays secured under normal driving and crash conditions, not on the slang label itself.

A common first-timer mistake is to assume any rear-hinged door is unsafe by default. That is too broad. The better question is whether the vehicle uses an approved latch system, whether the rear door can open only in the correct sequence, and whether it locks automatically once the car is moving.

Which modern cars still use them?

They survive in a small number of modern cars, mostly where packaging or brand identity makes the layout worth the extra complexity. Some sources list the Lincoln Continental, Mazda RX-8, Tesla Model X, and BMW i3 as examples, while others also point to the Mazda RX and Opel Meriva as modern cases.

Rolls-Royce is the clearest modern luxury association, and coach doors remain part of that brand’s image. The Mazda RX-8 and BMW i3 are the better-known mainstream exceptions, though neither makes the layout common. Car Keys also notes the Vauxhall Meriva as a modern example that meets restrictions.

Picture a narrow parking bay with a child seat in the back. A rear-hinged rear door can make buckling a child easier because the opening is larger and the side of the car may be less awkward to reach. The tradeoff is that the system must still be opened in the right order, which adds another step for the driver.

Why did carmakers move away from them?

Carmakers moved away from suicide doors because conventional doors are simpler to build, easier to package, and easier to certify across a wide range of buyers. As cars grew safer and faster, the older layout also carried a stronger reputation for risk, which made it a poor fit for mass-market use.

Child-seat access, parking-space clearance, and occupant loading all sound like reasons to keep the design. In practice, most buyers are better served by a normal front-hinged door because it is easier to use with less coordination, fewer moving parts, and fewer special opening rules.

The layout still has a place when a brand wants a formal rear seat or when a compact model needs better access without a long wheelbase. But the real-world tradeoff is clear: easier access for some passengers, more engineering complexity, and a narrower set of use cases.

Frequently asked questions

What is a suicide door on a car?

It is a rear-hinged car door that opens opposite a conventional front-hinged door. The term usually refers to a rear passenger door, especially on older cars or rare modern models. The layout can improve access, but it needs stronger latch and lock logic than a standard door.

Which modern cars still use suicide doors?

Modern examples include the Mazda RX-8, BMW i3, and some Rolls-Royce models that use the term coach doors. Other sources also name the Vauxhall Meriva, and list the Lincoln Continental and Tesla Model X. These remain exceptions, not a mainstream layout.

What is the difference between coach doors and suicide doors?

Coach doors is the manufacturer-friendly term many luxury brands use for rear-hinged doors. Suicide doors is the older slang term, usually used when the safety risk is part of the discussion. In practice, the hinge layout is similar, but the branding and the safety logic can differ by model.

Can a car have rear-hinged doors and still meet safety rules?

Yes. Modern rear-hinged doors can meet safety requirements when the car uses approved latches, automatic locking while moving, and opening-order logic that keeps the rear door from being opened at the wrong time. The same source notes that Europe allows rear-hinged rear doors only if front doors are opened first.
