When it comes to the Besturn B70, the first impression of many friends is that it is sturdy and durable. Indeed, from the first generation of Besturn B70 to today's first-class models, it adheres to the principle and bottom line of high quality in terms of design, development and quality control. However, many people have raised questions: compared with the old model, what improvements have been made in terms of safety and comfort of Besturn B70?Are the advantages continued?Is the short board made up?Recently, with these key questions, Besturn B70 has a special experience of "comparative dismantling", and the whole dismantling process is very enjoyable, let's take a look.
Previously, the 100km top speed rolling challenge was done for the *** Besturn B70, the vehicle moved at a speed of 100km h, and then the whole car was jacked up, rolled in the air to the limit, and finally landed. During the roll, the equipment fell to the ground, just like the drag racing collision scene in the movie. Because the scene was too tragic, we once thought that the Besturn B70 had a high probability of dying. But the actual situation is that there is no major damage to the structure of the vehicle, and the safety performance is so strong
In order to verify the authenticity, the program decided to "break and crush" the Besturn B70, and compare it with the old model to study the internal power of the vehicle.
Let's look at the anti-collision beam first, after the front and rear anti-collision beams of the new and old models are removed, we found that the front anti-collision beams of the new and old Besturn B70 are made of double-layer stamped steel plate structure, and the connection between the anti-collision beam and the body has an energy-absorbing box, and the front section of the body longitudinal beam has a collapse guidance area, in the event of a collision, these can absorb energy to a certain extent and protect the occupants in the car.
In terms of specific size, due to the different body structure, the length of the front impact beam of the original Besturn B70 is 6cm longer than that of the ** model, but the material of the ** model is thicker and relatively stronger. The rear impact beam is a single-layer design, and the ** model has a slight advantage in length, and the thickness difference is very small.
Through the dismantling of the anti-collision beam, it can be seen that FAW Besturn has always been very willing to use materials on the body hardware. Let's take a step closer and see if the body structure also performs well. After the staff removed all the seats and floors in the car, the floor of the vehicle was completely visible. **The bottom plate of the Besturn B70 has four beams, which is to cope with side impacts, and the regular gluing and wiring harness are professional and attentive in workmanship.
After the vehicle is raised, it can be seen that the new car adopts the double E-shaped and 3H structure that FAW Besturn is proud of, and the steel result is 76% high-strength steel and 22% hot-stamping steel, which is why it can withstand the 100 kilometers of top speed rolling test.
At the same time, the on-site staff directly cut the steel from the key positions such as the left and right sides of the Besturn B70 A-pillar, the A-pillar order and the inner and outer layers of the B-pillar, and tested their tensile strength by a professional laboratory after processing.
Above, from the perspective of body structure and materials, the safety performance of **Besturn B70 is completely OK. Both the second and third generations of the model have received five-star safety certification, which is also the first domestic car to receive five-star safety twice. Although the *** model has not yet been tested, if nothing else, this honor is inevitable.
Intelligent assisted driving is also an important part of vehicle safety, and in the chaos of intelligent driving, the AEB automatic emergency braking system is a major difficulty, for which professionals have tested it on closed road sections. The Besturn B70 is moving at a speed of 60km h, with a stopping distance of 166cm, and it is advancing at a speed of 66km h, and it is only a slight touch with the car in front. The results were good, and they were tested on slippery roads in light rain.
When it comes to vehicle comfort, most users focus on the seat, but in fact, quietness is the key to testing whether a car is cost-effective and has advanced craftsmanship. The use of sound-absorbing cotton will greatly affect quietness, so in the process of comparison and disassembly, the staff specially disassembled the door panel to intuitively compare the sound-absorbing cotton materials.
After comparison, we found that the original Besturn B70 has a very solid sound-absorbing cotton material in the firewall, front and rear four door panels, wheels, and the bottom of the car, and even the upper part of the tail box has a large amount of sound-absorbing cotton. **Besturn B70 has evolved on this basis, in addition to the sound-absorbing cotton that can be found everywhere around the vehicle, it also uses foam materials and thick foam, which can prevent noise from entering the car from outside the car.
At the same time, the staff also made a real evaluation of the intelligent technology and detail process such as the car machine response, body gaps, and paint surface of the **B70, and the results were very satisfactory. It can be said that from hardware to software, the Besturn B70 is armed to the teeth, and it is a genuine national high-quality car.
Write at the end. To be honest, we didn't expect the Besturn B70 to be so attentive in the invisible place until the test results came in. The new car does not stay at the level of "enough on the line", but provides the best value through a safer body mechanism and more reliable detail quality. With the blessing of many "hidden" and "explicit" advantages, I believe that the Besturn B70 will become a cost-effective family sedan in the hearts of more people.
