Have you ever played Stacked Arhats? This is a very old game, which was originally composed of multi-layered cross-legged arhats, so it was called stacked arhats. Over time, it gradually evolved into a variety of skill shapes, such as cheerleading, gymnastics performances, acrobatic performances often appeared. In real life, there is a car company that often stacks luohans, yes! It was Volvo.
Volvo has been playing with stacked Luohan since the last century, and in the 60s, it used 140 series models to stack 7 layers. In the 1980s, four volvo classic models were stacked on top of the 850 models. Although the sharpness of the previous photos is not high enough, the Volvo model at the bottom can be faintly seen and almost intact.
How does Volvo's Stacked Rohan play today?
In April 2021, Mr. Yuan Xiaolin, Senior Vice President of Volvo Cars Group Worldwide and President and CEO of Volvo Cars Asia Pacific, was leisurely on the phone in a Volvo XC60 car. On the surface, Yuan Zong was chatting happily, but there were 6 identical XC60s stacked above the vehicle where Yuan Zong was. In the state of "Tarzan pressure top", you can still talk without changing the color, which shows how much trust you have in the safety of Volvo XC60, and Volvo is synonymous with the security community. So what "martial arts" does Volvo use? The answer is: boron steel!
How good is boron steel?
Boron steel has a completely different strength from ordinary steel, tensile strength of up to 1300-1600MPa, yield strength of 1000Mpa, per square centimeter can withstand more than 10 tons of pressure, 3-4 times stronger than ordinary steel. There may be no concept in this way, if you use ordinary steel and boron steel to make a sword each, after the confrontation, ordinary steel must be potholes, and boron steel will remain firm. With steel of this strength used on Volvo's body, the safety of the members in the car can rise in a straight line.
Not all cars will use boron steel, and the proportion of Boron steel used in the Volvo XC60 is close to 40%, which is more than 4 times higher than the industry level. At the same time, boron steel is used on the roof, A-pillar and other positions that can most effectively protect passengers in the event of an accident. The use of ARO welding technology to improve the welding firmness, completely better than the industry level.
Boron steel + cage body is really safe
There is good steel, of course, also need to have a good structure, just like origami, correct and reasonable origami can make it stronger, and even made into a weapon. Volvo has adopted a cage body structure since 1944, and the high-strength cockpit area can ensure that the occupant compartment is less deformed when it is collided and squeezed, providing sufficient living space for the members of the car. Whether it is a frontal collision or a roof pressure resistance, it provides strong arch support to ensure safety. (The picture below shows the XC60 falling from a height of 30 meters, the AB column is not damaged, and the door is easily opened.) ）
50 tons of truck overturned, the owner of the Volvo car was pressed unscathed?
In June 2020, a truck of about 50 tons rolled over, just in time to crush a Volvo XC60. After about 2 hours of rescue, the owner's family was all rescued. Surprisingly, the owner's family turned out to be unscathed, some people say that this is volvo's best commercial, but in fact, this is just a normal performance of a Volvo XC60. But if you change to other models, can you have the same result? Maybe the consequences are unimaginable!
Not only was there a 50-ton truck rollover, one day in 2018, a large tree fell down after a rainstorm and pressed on the roof of a Volvo S60L. Under almost the same conditions, cases of serious deformation of other models occur from time to time.
Volvo has always put the safety of consumers' lives first, and has made tangible moves. From the invention of seat belts and the sharing of patents without compensation, to the large-scale application of boron steel to the body, every step is based on safety. Many industry insiders say that Volvo has saved more than 1 million lives, and even called Volvo a tank on the road. In fact, as a luxury brand, Volvo is more than BBA in terms of quality, style, driving, handling, etc. Therefore, the tank on the road is not accurate, but the luxury tank on the road.
