Making Safe Vehicles

In order to further accelerate its new technology development, including safety technology and electrification for making products more environmentally friendly, SUBARU’s development systems are based on SUBARU’s overall safety philosophy, which focuses on delivering the world’s highest standard of safety and peace of mind for all passengers. This marks a pivot from a system based on functional organizations (e.g., vehicle bodies and power units) to an organic combination along value and functional axes.

Aiming for Zero Fatal Traffic Accidents in 2030

SUBARU has four safety areas. Primary Safety involves design that allows for a good field of vision and does not make the driver or passengers feel tired. Active Safety is controllability that allows a driver to avoid an obstacle that is in front of them, and to continue driving after avoiding it. Preventive Safety refers to pre-crash braking, as represented by EyeSight. And Passive Safety involves damage mitigation to protect the driver and passengers in the event that an accident does occur. By polishing these four safety areas, we intend to achieve a low rate of fatal traffic accidents in the real world.
SUBARU’s intention does not lie in changing everything to automatic, but rather in “Respect of what humans are good at and leave what humans are not good at to automobiles for safe transportation.” With this idea, SUBARU has polished our driver assist technology. Going forward, the evolution of Advanced Driver Assistance System (ADAS) will make it possible to slow down and avoid collisions in high-speed zones and on large bends, which is expected to be of further assistance in preventing and mitigating accidents. At the same time, the current situation reveals an issue where approximately 30% of fatal traffic accidents, primarily caused by no-fault accidents, remain unsolved. We also recognize the challenge of responding to more severe forms of accidents, such as collisions involving cyclists.
Facing these problems, SUBARU is aiming to achieve zero fatal traffic accidents by 2030 by applying our intelligence technologies in the fields of Primary Safety, Active Safety, Preventive Safety, and Passive Safety, plus Connected Safety.

Achieving a Low Rate of Fatal Traffic Accidents in the U.S. and Japan

From FYE March 2009 to FYE March 2023, we carried out an investigation on the number of fatal traffic accidents involving SUBARU cars sold in the U.S., a major market, and those sold in Japan. In the U.S., SUBARU cars have maintained a rate of fatal traffic accidents that is lower than the average for major selling brands in the U.S. for 15 consecutive years. In Japan, SUBARU cars also show a rate of fatal traffic accidents that is lower than the average for other auto manufacturers in the country for 15 consecutive years.

Primary Safety

SUBARU’s predecessor was an aircraft manufacturer. With aircraft, it is necessary to pursue “accident-free vehicle” design, as even a slight error in operation or judgment can cause a severe accident. Inheriting the philosophy of safety, SUBARU focuses on the primary design such as surface and operation, thereby we pursue clear, useful, and comfortable space where the driver can concentrate on driving easily.

Visibility Optimized for Every Condition

Early detection of danger can help avoid accidents. SUBARU has concentrated efforts on minimizing blind spots and improving visibility even under difficult conditions such as driving in rain or at night.

Optimal Driving Position

Optimal driving position allows drivers to move naturally, reducing fatigue and helping to improve safety and comfort while driving.
It also helps the driver to steer the car precisely for taking evasive action when the risk of an accident occurs. SUBARU’s cockpit is designed to be adjusted so that every driver can find their optimal driving position.

Intuitive Interface

Drivers can sometimes have a lapse in concentration when checking the navigation screen or adjusting the air conditioning. To prevent this from happening, SUBARU has designed an interface layout that is easy to use. For example, the navigation screen is placed so that the driver does not need to shift their line of vision too far, while the air-conditioning system and audio controls use switches that allow for intuitive operation so that drivers do not have to take their eyes off the road.

Digital Multi-View Monitor

The digital Multi-View Monitor is a function that contributes to primary safety by displaying the vehicle’s surroundings and reduces the size of blind spots.
It has particular value in that it synthesizes digital camera footage from front, rear, left, and right perspectives, allowing for a comprehensive view of the vehicle’s surroundings on a single screen. We have prepared two types of screen display that allow drivers to see the entire area around the vehicle: a top view that displays the surrounding area as if looking straight down at the car, and a 3D view that allows the driver to choose from eight different angles to display the area as if looking at the car from above at an angle.
This technology is installed to the Crosstrek and Impreza as of FYE March 2023, the Ascent as of FYE March 2024, and the Forester as of FYE March 2025.

Furthermore, in addition to the aforementioned functions, the FYE March 2024 Levorg and WRX (for the Japanese market) and Levorg Layback will be the first SUBARU models to feature the new Auto Mode function.
This function automatically displays the front view and partial top view (the front part of the top view) at low speeds, so even in situations where there are many blind spots and/or a succession of narrow intersections, as often found in residential areas, drivers can check blind spots ahead at a glance.

Active Safety

For SUBARU, “driving” means more than simply delivering enjoyment. It is an important factor in increasing safety.
To make it possible to avoid the situation safely if an accident occurs. To be able to drive safely in various weather conditions and road surfaces, the same way as during normal conditions. SUBARU has fine-tuned all the basic functions of a vehicle—driving, turning, and stopping—to develop vehicles that offer exceptional stability and predictable control in the most challenging conditions, which makes cars safer and more trustworthy.

Driving Stability

On the foundation of outstanding core performance, SUBARU tempers the body and suspension of its vehicles along with employing vehicle control devices that increase drivability, creating stable driving that provides peace of mind to drivers and passengers.

Line Traceability

Imagine being able to drive into a slippery corner on a snowy or rainy day without unpredictable car movement, turn exactly as intended through the corner, and head out of the corner smoothly. SUBARU includes a number of functions that make smooth cornering a reality.

Braking Performance

Braking performance is directly related to a car’s safety, particularly its hazard avoidance capabilities. SUBARU goes beyond polishing such performance, also placing great focus on peace of mind. Brakes that provide peace of mind work as predicted every time. SUBARU repeatedly tests in all environments and on all road surfaces in our quest to deliver brakes that are easy to operate regardless of weather and that react quickly at the critical moment.

Technology: Active Safety (Japanese version only)

Preventive Safety

Our ultimate goal is to eliminate traffic accidents. To achieve this goal, SUBARU has spent more than 20 years developing driver assistance systems. The inexpensive and highly practical EyeSight has become widespread in markets around the world, pioneering advanced safety technology. In 2020, EyeSight was reborn to help aid our goal of zero fatal traffic accidents in 2030.

EyeSight Core Technology

We have revamped our stereo cameras at the core of EyeSight’s driver assistance. In this upgraded system, viewing angles are wider and image recognition is improved, giving it better-than-ever capabilities to distinguish cars, pedestrians, road lines, and other elements while driving. Thanks to improved control performance, driving SUBARU cars is now smoother and safer than ever before. Furthermore, with these new stereo cameras as a core driver and combined with four radar sensors on the front and rear of the vehicle, plus rear sonar, our system can monitor the car’s entire surroundings. This offers support to drivers in a greater variety of situations and a higher level of safety. Beginning with the Levorg in FYE March 2021, we have expanded the lineup of vehicles equipped with this technology, including the WRX, Outback, and Forester in FYE March 2022, the Crosstrek and new Impreza in FYE March 2023, the Levorg Layback in FYE March 2024, and the new Forester in FYE March 2025.

Collision Avoidance Support

Our new stereo cameras greatly expand the usable scope of pre-crash braking. It protects drivers and passengers in tense situations on the road, like oncoming vehicles, crossing pedestrians, or crossing bicycles during a turn, or vehicles approaching from the front. Approximately 40% of vehicle-to-vehicle accidents occur in situations like these. We believe our system significantly mitigates these traffic accidents.
To further improve our collision avoidance performance, we have newly adopted a wide-angle single-lens camera in the Outback, Ascent, Crosstrek, and new Impreza. Utilizing an even broader field of view than the new stereo camera, the wide-angle single-lens camera enables collision avoidance and reduces the potential for harm in scenarios involving head-on encounters with cyclists and incidents involving pedestrians. The system has been incorporated in the Levorg, WRX, and Levorg Layback as of FYE March 2024, and will be incorporated in the new Forester in FYE March 2025.
The EyeSight system has also been equipped in the BRZ manual transmission model in FYE March 2024. By offering high-performance collision avoidance assistance to a broader range of customers, we have taken a significant step toward achieving zero fatal traffic accidents in 2030.

Reducing Operating Burden

SUBARU believes that reducing operating burden leads to greater safety.
In 2020, EyeSight X was born, an evolutionary advance from our EyeSight system. This new system combines high-precision 3D maps and satellite positional data to recognize road conditions well ahead of the vehicle, beyond the detection range of stereo cameras and radar. These high-precision 3D maps constitute an important element technology at the heart of next-generation driver assistance. SUBARU was one of the first among automotive companies to apply this technology and bring it to market. It helps reduce driver burden especially on long hauls, offering a luxurious touring experience. It does this through a variety of features, including speed control at optimal levels just before curves and toll booths, active lane change assistance, and assistance during traffic congestion, including hands-off and start-and-stop support. Our ongoing efforts to expand the integration of the EyeSight X system included its implementation across all grades of the Outback for the Japanese market in FYE March 2022 and for all grades of the Levorg, WRX, and Levorg Layback, also for Japan, in FYE March 2024. We are committed to offering comfortable transportation to a wider range of customers.

Support for Safe Driving

We are also expanding the implementation of the Driver Emergency Support System to prepare for unforeseen circumstances. If the driver’s hands come off the steering wheel for a long time while Active Lane Keep is engaged, or when the system detects a distracted or drowsy driver while hands-off congestion driving assistance is active, it will warn the user. If the driver does not move the steering wheel even after the warning, the system determines that an emergency situation is underway, activating hazard lights and the car horn to inform nearby vehicles of the situation and gradually slowing the vehicle to a stop. Introduced for the first time in the Levorg released for the Japanese market in FYE March 2021, this system was also incorporated into the WRX and Outback for Japan in FYE March 2022.
The Crosstrek and new Impreza for the Japanese market are equipped with features that are integrated with SUBARU STARLINK. When the Driver Emergency Support System is activated, it automatically connects to a call center, allowing for quicker response in an emergency.
In the new Forester for FYE March 2025, we are strengthening the Driver Monitoring System integration. Even if the driver is operating the steering wheel, it will activate if it detects that the driver is looking away from the road or falling asleep. A pulse brake warning has also been added to give the driver a physical warning of an abnormality.

Technology: Preventive Safety (Japanese version only)

Passive Safety

Since the time of “Subaru 360,” when we started mass production, SUBARU has positioned safety as one basic function that cars should have. Also, we have been performing our own original damage mitigation tests that include protecting pedestrians since the 1960s—a time before thinking regarding damage mitigation had yet to be fully instilled. SUBARU’s damage mitigation functions take into consideration not only the driver and passengers but also pedestrians as well as the possibility of harm to the occupants of other vehicles. These functions have received high evaluations both in Japan and around the world.

New Ring-Shaped Reinforcement Frame

SUBARU has a uniquely safe body design. In the cabin, the pillar and frame combine to form a “cage.” The purpose of this is to protect from deformation regardless of the angle from which the vehicle is struck. A relatively crushable zone is provided to disperse and absorb the shock of a powerful impact. This gives SUBARU vehicles high collision absorption performance against impacts from any direction.

Front-end/Rear-end Collisions

Even small components can become as deadly as weapons when receiving the powerful force of a collision. Based on that fact, SUBARU equips its vehicles with a horizontally-opposed engine, which has the advantage of being able to effectively absorb the energy from a collision. During a front-end collision, not only can it easily slip under the floor, but the frame that absorbs the shock can extend symmetrically as well as straight. Each component of the cabin is made of shock-absorbing materials in order to protect lives.

Side Collisions/Rollovers

To protect the driver and passengers during a side collision, an extremely rigid side door beam is installed in the door. In addition to that, the new high-rigidity Ring-Shaped Reinforcement Frame protects the cabin space during a collision or rollover. Furthermore, several kinds of airbags and energy-absorbing materials line the entire car, protecting every person inside the cabin.

Protecting Pedestrians

SUBARU strives to protect not only our drivers and passengers but also pedestrians.
For example, our horizontally-opposed engines have a wide energy absorption space between the front hood and engine unit. This reduces damage from being struck by the top of the hood, which is a highly probable head injury for pedestrians.
Furthermore, our cars are designed to absorb the shock from components such as the hinge and hood stay. SUBARU’s four safety areas, which take into consideration all forms of safety, can be found in all of our designs and initiatives, and have been carried over to our BEV. As an example, we were the first Japanese automobile manufacturer to install pedestrian protection airbags, which have now been equipped in seven models.

Safety Recognized around the World

SUBARU’s damage mitigation features have received high evaluations in safety assessments from countries all around the world.

Technology: Passive Safety (Japanese version only)

Connected Safety

We use connection technology and data based on SUBARU’s four safety areas of Primary Safety, Active Safety, Preventive Safety, and Passive Safety, and develop new technologies and services to further pursue safety. Our vehicles feature the Advanced Automatic Collision Notification (AACN^*) system. In the event of a collision that triggers the airbags, it automatically connects to a call center and coordinates with the police, emergency services, and medical institutions, aiding in more speedy rescue activities. D-Call Net, an element of this system, is installed in vehicles for the Japanese market. When a vehicle is involved in a traffic accident, information such as the direction of impact, speed, severity of impact, and whether or not the occupants were wearing seatbelts is immediately sent to the D-Call Net server. From this information, the severity of the injuries to the occupants is automatically estimated, and if necessary, a request is made for a medical helicopter.
In addition, SUBARU’s mass market car models are equipped with the Driver Monitoring System, which attentively watches over the state of the driver. It detects when the driver looks away or shows signs of sleepiness, and sends an alert. Going forward, we will couple it with various controls.

This system estimates the severity of injuries to passengers in the event of a traffic accident involving a car equipped with an event data recorder (EDR) in its airbag system, and notifies the fire department and/or medical helicopter service base hospital, based on data sent automatically from the EDR and using a certain algorithm.

Car Assessments

SUBARU undergoes safety performance testing and assessment of public organizations in and out of Japan including JNCAP^*1 in Japan, IIHS^*2 and U.S. NCAP^*3 in the U.S., Euro NCAP^*4 in Europe, and ANCAP^*5 in Australia, and has gained the highest rank of assessment in most of them.
In FYE March 2024, the Crosstrek and Impreza won the JNCAP Five Star Vehicle Safety Performance 2023 Award, the highest rating in the JNCAP. Furthermore, of the five star award winners, the vehicles also won the JNCAP Five Star Vehicle Safety Performance 2023 Best Award, only awarded to the vehicles earning the highest overall points. At the IIHS, as of May 2024, one of SUBARU’s 2024MY (model year) vehicles had won the organization’s 2024 TOP SAFETY PICK+ (TSP+) Award, and three vehicles had won its 2024 TOP SAFETY PICK (TSP) Award. In the U.S. New Car Assessment Program (NCAP), two 2025MY models and five 2024MY models received 5-Star Safety Ratings in the overall rating.

Safety Is Our DNA

Since its founding, the core of the SUBARU Group, an organization with roots in the aircraft industry, has been to put people first and to engage in Human-Oriented Monozukuri. We believe that safety is the most critical basic function for cars. Since the launch of Subaru 360 more than half a century ago, we have passed this belief on as an element of our company DNA, making relentless efforts in every era to perfect the most essential functions of a car—driving, turning, and stopping—reflected in our unique engineering know-how, including all-around safety performance. Looking to the future, SUBARU will continue to engage in automotive manufacturing with a philosophy of “All-Around Safety” and maximum emphasis on safety performance.
