As a clichéd issue, automobile safety has received more and more attention in recent years, especially whenever the latest evaluation results of the China Insurance R&D cloth, which has the reputation of "quality mirror", can always cause heated discussion in the industry.
On April 6, China Insurance Research Institute released the test results of the latest batch of models, covering a total of 6 SUVs and 1 MPV, and they are all popular models in the market. It is worth noting that this time the Insurance Research Institute rarely tested two models of a brand at the same time, that is, Buick GL8 ES Luzun and Oncovey S, which believe that many users are more concerned about the collision results of GL8, today we will talk about their performance.
Oncovey S, save life to preserve value
When it comes to Oncovi S, the author remembers most deeply that when netizens talked about the retention rate, some car owners said: "Oncovey S is to save life to preserve value", which also shows the owner's recognition of the safety of OncoveY S. We are also willing to see more consumers pay attention to car safety, because only when safety is ensured, there is a so-called retention rate.
Judging from the results of the R&D of this china insurance, OncoveY S has obtained excellent "G" results in the protection of passengers and pedestrians in the car.
First of all, the most stringent 25% bias collision, from the official release of the video can be seen, the collision occurred at the moment, the A pillar of the Oncovi S is intact, the engine compartment is fully absorbed, and the crew compartment maintains a good integrity; at the same time, the side air curtain, the airbag pops out quickly, and the seat belt restraint device acts quickly, ensuring that the key parts of the driver and occupants are well protected.
The same is true for side collisions, where the side air curtain quickly pops open at the moment of the collision, protecting the key parts of the driver and occupants, and the distance between the B-pillar and the centerline of the driver's seat is within the excellent standard.
In the roof strength test, the peak load of the Oncovi S reached 82239N, and the load-to-mass ratio was 4.99. In other words, the oncovi S roof can withstand up to 4.99 times the pressure of self-weight, and it has also received excellent evaluations.
In addition, in the seat/headrest test, the outside pedestrian protection test and other projects, Oncovi S has received G excellent evaluation. The "M" score was obtained in the vehicle assistance safety project, and there is still some room for improvement in this regard. Overall, the strength of the Encore S lies in the strength of the body and the protection of the crew compartment.
The proportion of high-strength steel for oncovi S body parts has reached 75%, of which the ultra-high-strength steel with a yield strength of more than 800Mpa has reached 27.5%, while key parts such as A-pillar, B-pillar, driver's foot guard plate and other key parts use ultra-high-strength thermoformed steel with a yield strength of 1500Mpa in a large area to ensure the stability of the body structure under extreme conditions.
Not only that, Oncovi S also made full safety design and optimization for the different types of collisions that may occur in the vehicle, using a reasonable body structure and force transmission path design to effectively alleviate the body shape change caused by the collision and fully protect the life safety of the occupants in the car.
The security evolution of the Buick GL8
After talking about the Encore S, let's take a look at gl8 ES Lu Zun. GL8 is also the second time to be selected by the China Insurance Research Institute to participate in the test, the first test time was in 2018, when the 2017 version of the test procedure was used, which is also rare in the testing career of the China Insurance Research Institute.
At the same time, Buick GL8 ES Luzun is also the only MPV model among the 7 models in this test, which makes people wonder whether the GL8 of the second strike can withstand the test of the more stringent 2020 version of the regulations.
In this test, the GL8 occupant and pedestrian safety scores were "A" good, and in the 2018 Mid-Security Research Institute's test results of the 2017 Buick GL8, the safety score of the occupants in the car was "M" at that time, and it can be seen that in terms of collision, GL8 has optimized and improved the body structure to a certain extent.
In the most concerned frontal 25% bias collision, the GL8's A-pillar structure is relatively complete, the cockpit has not been invaded too much after the collision, and the airbags and side air curtains that quickly bounce off have fully protected the driver and passengers. The GL8 body can also be observed "sliding" to the other side in the event of a collision to break down the impact of the front barrier on the cockpit.
The damage and deformation of the B-pillar of the side impact are within the acceptable range, the preservation is relatively intact, the structure does not cause obvious damage to the passengers, and the side air curtain pops out quickly, which protects the passengers in the car.
In fact, compared with cars and SUVs, MPV models have a natural disadvantage in crash tests, due to the pursuit of maximum space performance, in the same body length, MPV can only move the A-pillar and cockpit forward, in order to better arrange the second row of VIP seats and ensure the third row of seating space, while leaving enough trunk space.
The design of the short front end, the collapse energy absorption area, which is crucial for collision safety, has been compressed, and the collision performance is naturally not so good.
In addition to the improvement of collisions, gl8 active safety assistance system is also quite bright, in this regard, GL8 has been performing well, for the popularization and application of intelligent assisted driving, in the field of MPV is relatively leading. With this system, accidents can be avoided in advance to a large extent.
Judging from the results of Zhongbao's R&D cloth, Buick GL8 has obtained G excellent evaluation on the vehicle auxiliary safety index, including vehicle-to-car and vehicle-to-cyclist AEB, lane keeping assist LSS and other items, Buick GL8 is passed by a super high scoring rate, and the final total score of vehicle auxiliary safety reached 94.18, a veritable excellent evaluation.
Not long ago, Buick also launched the first eCruisePro advanced intelligent driver assistance system OTA remote upgrade, adding ILC driver command lane change function. With mobile EyeQ4 and 12 ultrasonic radars, 5 high-performance millimeter-wave radars, 4 megapixel HD panoramic cameras and 1 2-megapixel wide-angle HD camera, the Buick GL8's travel experience has become safer, smarter and more efficient.
The safety DNA of the Buick brand
Looking back at Buick's century-old history, it has always been accompanied by the implementation of safety in its DNA.
For example, after the three-point seat belt was patented, when the market was hostile to this "new thing", Buick was the first car company in the world to wear a three-point seat belt as standard.
For example, GM engineers invented the rear turn signal for the first time, and innovatively introduced an off-neutral crash test to simulate the collision performance of passengers in different states.
In addition, like "BFI integrated body", with the help of computer finite element model technology, the design and analysis of body performance is carried out by establishing more than 3 million finite element units, and then the connection between the body frame and the optimization of the deformation structure of the vehicle when the collision occurs. The popularity of intelligent assisted driving, the creation of a safe user service experience such as OnStar, etc., are enough to show Buick's emphasis on safety.
Write at the end:
Car safety is closely related to everyone, crash testing only provides us with a reference and judgment of the basis, we need to look at it rationally, and the situation in real life will undoubtedly be more complex, manufacturers in the continuous optimization and improvement at the same time, we also have to improve their own safety awareness.
In fact, from the perspective of the collision results of Buick this time, there are points to see, there are deficiencies, but it is gratifying that in the face of the voice of the market, in the face of user feedback, it is the responsibility of a car company, that is, the market is developing in a better direction, which is not what consumers are willing to see
