A sturdy car body by itself does not necessarily make the car safe. If the body is simply rigid, maybe the car itself will not be damaged much during a crash, but the people inside end up taking the full impact of the collision, which is very dangerous. For example, if you place a raw egg inside a sturdy square box and strike the box hard, the box will not be damaged but the egg will break. However, if a shock-absorbing material such as a sponge is placed inside the box, the egg will not break.
When a crash occurs, it is much more important to ensure the safety of the people inside the car than to try to save the car itself. That is our first priority. We use hard and strong steel to make a cabin that will not deform if there is a collision, so it will protect the people inside. We call this a high-rigidity cabin. The front or rear portion of the car body is designed to crumple first, in order to absorb the impact of the crash. The sturdy cabin is designed to let the remaining impact force escape safely and protect the people inside. Toyota developed such a safe car body to satisfy the safety standards we adopted on our own - the highest safety levels in the world. We call this car body a Global Outstanding Assessment or GOA body.
In answer to your question, let's look at how much impact it takes to deform the cabin. The GOA body is able to keep the cabin intact with only minor deformation during an offset frontal collision test (a test where the test car hits the corner of a square pillar) at a speed of 60km/h. This GOA body exceeds both the regular Japanese and world standards. Toyota plans to continue to research and develop ever safer cars.
Regardless of how safe cars are made, if their drivers ignore traffic rules or drive recklessly, traffic accidents will not disappear. That is why Toyota holds driving courses all over Japan, helping people learn safe driving practices. And we have a request for you too. When you get in a car with your mom or dad, please be sure to buckle up your seatbelt. You may not think it's such a big deal, but it is very important. A seatbelt can save your life if you're ever involved in an accident.
