A few days ago, I went to the 4S shop to replace the start-stop battery. When I was wandering around the exhibition hall, I saw an old XC60 in the exhibition hall. After the body was disassembled and disassembled, I could see in detail Volvo Cars ‘efforts to ensure the safety of people inside the car. Regardless of cost and unremitting pursuit of safety performance, it is really a model in the industry.
Nowadays, cars are a bulk consumer goods that improve the quality of life and have basically reached a state that everyone can afford. Therefore, each car brand has its own distinctive selling points, including a sense of technology and a tendency to control performance. However,”safety” is a unified consensus. However, for Volvo Cars, which has unique insights into safety, safety is everything. cornerstone. If a car cannot ensure the safety of the people inside it, everything else is like a castle in the air and extremely fragile.
Volvo cars with the new SPA modular platform all use ultra-high-strength cage bodies. Key parts including A, B and C columns are made of boron steel. When it comes to boron steel, many people may not know much about it. Let me give you a brief introduction here: this steel is made of boron based alloy elements. Boron steel has extremely high material strength properties. Its tensile strength is as high as 1,300 – 1,600 MPa, and its yield strength is more than 1000MPa. While the tensile strength of ordinary high-strength steel plates is only 400 – 450MPa, which is fully higher than that of ordinary steel plates. It has increased by 4 times, and the plasticity, toughness and tensile strength of boron steel are much stronger than ordinary steel plates. Because boron steel itself has many advantages, it can be made into complex shapes and welded to the main parts of the car body to a certain extent to reduce the weight of the car body, thereby controlling fuel consumption, which can be said to achieve multiple goals at one stroke.
All Volvo cars on the new SPA platform use boron steel, and some models use a maximum of 30%. There are not many such conscientious car companies in China that do not care about cost for safety.
As Volvo Cars founder Gustav Larsson & Arthur Gebbleson said-“The guiding principle of everything we do is and must be-safety.”
