Protection against Collisions.
Since embarking on the business of car production, SUBARU has above all else focused on development of “safety technology” to provide protection...
Ring-Shaped Reinforcement Frames body
The heart of all-around safety
Delicately cushioning passengers from the shock of a collision
Submarining to prevent injury to passengers
- Subaru cars have traditionally been powered by the Horizontally-Opposed SUBARU BOXER Engine. With an inherently low centre of gravity, the engine allows the transmission and other components in the drivetrain to be positioned in a straight, symmetrical line. This design allows the engine to “submarine” – or slide – under the floor during a frontal collision, and has been proven to be much safer than other engines, where the transmission and other drivetrain components are often pushed into the cabin during a collision.

Front passenger seat restraints for unexpected accidents
- The front seat seatbelts of Subaru cars have a number of features for added safety. The pretensioner tightens the seatbelt instantaneously during a collision, holding passengers more firmly in their seats. The load limiter maintains tension in the seatbelt, reducing injury to the passenger’s chest. And the seatbelt adjuster changes the position of the shoulder strap to suit different body sizes.
Three-point seatbelts in all seats for better safety
- All rear seats in Subaru cars use three-point seatbelts to firmly hold the waist and chest area of passengers. All retractors feature a child seat (ALR) mechanism.
Driver’s seat and passenger’s seat SRS airbags
Instantly inflatable cushions
- The driver’s seat and passenger’s seat SRS airbags work in tandem with seatbelts to protect passengers. These are folded into a compact size and stored within the steering wheel and dashboard, and inflate instantaneously to form airbags during a collision, providing added protection for the passengers.
Shock absorbing seat design
Reducing passenger whiplash and injury
- Seats play an extremely important role in protecting passengers during a rear-end collision. Standard front seats in Subaru cars incorporate mechanisms to reduce these shocks in three ways: (1) Active headrests to hold the head firmly. (2) Absorb shocks to the head using energy absorbing headrests with a dual layer internal structure, thus minimising neck whiplash. (3) The entire seatback absorbs the shock that throws passengers backwards, minimising the shock transmitted to passengers.Shock absorbing materials have also been used for the ceiling and other cabin surfaces to reduce the shock transferred to the heads of passengers during a collision.
Eliminating injury to lower legs
- If the car is involved in frontal collision, the car’s pedals often move backward, causing injuries to the driver’s leg. All Subaru cars employ auto-retracting pedals to minimise this type of injury. Brake pedals are retracted with the use of a catch and shock absorbing clutch pedals (MT models) limit changes in pedal position. Footrests (AT models) also use shock absorbing material to reduce injury to the driver’s feet.
Side/Offset Collision, Roll-over
Body structure that protects passengers during a side collision or roll-over
Protection against roll-overs
Extremely safe body to help protect cabin space during a roll-over
- Every SUBARU boasts exceptional driving stability owing to the low centre of gravity design and suspension system that offers excellent traction. In essence, SUBARUs are engineered to have a low risk of a roll-over. If the car is involved in a roll-over for whatever reason, the high rigidity of the Ring-Shaped Reinforcement Frames body and deformation of the shock absorbing materials help to prevent cabin space from being compromised. The shock absorbing materials used throughout the ceiling and cabin interior, front side SRS airbags/curtain SRS airbags and other safety features also help to reduce any impact delivered to the heads of all passengers.
SRS side/curtain airbags
For the protection of all passengers
- During a side collision, side airbags installed within the outer contours of the driver’s seat and passenger’s seat inflate to protect the chest and waist area of the driver or passenger. During a roll-over or side collision, curtain airbags inflate from the interior side of the roof, protecting the head and neck area of the driver, passenger and those sitting in the rear seats. Curtain airbags provide a much larger protective area around the head, and are effective for passengers of various body sizes and sitting positions.
Side door beams
First line of protection during a side collision
- Reinforcing beams have been added within the door frames, which help prevent distortion to the cabin during side collisions and ensure the safety of passengers sitting inside. These beams have been installed as standard in all Subaru models since the release of the second generation Legacy in 1993.
Shock absorbing pillars/roof trim
No expense spared for absorbing energy
- A shock absorbing structure has been used within each surface around the driver’s seat and passenger’s seat headspace to provide better protection during a collision.
Pedestrian Protection and Compatibility
A safe design philosophy protecting pedestrian lives and reducing injury
Front of car (bumper)
Reduced injury to pedestrian legs
- A shock absorbing structure has been used around the front bumper area, which has the highest probability of striking against the legs of pedestrians during an accident. This feature absorbs collision energy that would otherwise be transmitted to the pedestrian’s legs, thereby protecting their knee joints and other body parts from potential injury.
Around the bonnet
Preventing injury to pedestrians wherever possible
- There are usually hard, solid objects such as the engine placed immediately beneath the bonnet, which limits how much shock can be absorbed in that area. A Horizontally-Opposed Engine however, sits much lower in the engine bay than other engine types. This results in ample clearance between the bonnet and the top of the engine, giving rise to a large crushable zone within the engine bay. In addition to using steel bonnets, which have a high level of shock absorption, a frame is installed to ensure that shocks are distributed evenly throughout the bonnet area. The front end of the bonnet also features a crushable design that can buckle easily. Even the hinges and bonnet gas struts have been designed to minimise injury to pedestrians.
Detachable modular front wipers
Preventing injury to pedestrian head area
- The front wipers are designed so that the wiper shafts detach when subjected to shock. With this modular layout, injury to pedestrians from the wiper ends is minimised in the event that a pedestrian is thrown on top of the car’s bonnet.
Frontal collision compatibility
Cars built with others in mind
- In an accident involving two cars, the smaller or lighter of the two usually sustains more damage during the collision. Subaru has taken a broad stance for developing cars to ensure an adequate level of safety towards the other car with an efficient, shock absorbing frame, while providing a solid cabin with which to protect its occupants, holding them firmly in place with fail-safe safety restraints.
