In the crash test results released by C-NCAP this year, Xingtu TXL ranked first among mid-level SUVs since the implementation of C-NCAP’s new rules with a comprehensive score of 93.6, and received a 5-star rating. On November 21, Xingtu held an M3X Mars architecture safety technology sharing meeting in Guangzhou, explaining the safety secrets of its current high-performance global M3X Mars architecture.
The "M3X Mars Architecture" is based on Chery Automobile's 23 years of mature vehicle manufacturing experience and the R&D system structure of five major R&D centers, and is jointly created with Magna. From the perspective of platform scalability, the M3X Mars architecture adopts a modular concept and is compatible with all categories from A-class to C-class cars, SUVs, MPVs, and new energy products.
At present, Xingtu has launched a number of products, and Xingtu TXL is undoubtedly the one with flagship positioning. In terms of safety, the Xingtu TXL model developed based on the M3X platform adopts a cage-type energy-absorbing body with a high-strength steel coverage ratio of 78%. The A and B pillars use a large amount of 1500Mpa hot-formed steel and can brake at 100km/h-0 The distance is 36.5 meters.
The 5-star C-NCAP crash test result was not surprising to Dr. Xu Youzhong, Assistant General Manager of Chery Automobile and Executive Director of the Product Development Management Center. Xu Youzhong revealed that in fact, this model has experienced 1 million hours of simulated collisions when it was developed, and has 25 offset collision patent blessings. Its internal evaluation has already met the most stringent crash IIHS (Insurance for Highway Safety) Association) standards. In addition, Chery took the lead in building a collision laboratory as early as 2008. It is the first laboratory in China that can meet American standards and can meet all global standards. It is also the only national engineering laboratory authorized and recognized by the National Development and Reform Commission. This engineering laboratory It was put into use in 2010, so Xingtu's products meet all crash standards.
Professor Zhu Xichan from the School of Automotive Engineering of Tongji University once participated in the construction of Chery’s multi-track collision laboratory. According to Professor Zhu Xichan, the collision laboratory built by Chery currently has eight tracks. In the past, to complete a collision standard experiment, only one runway and a fixed obstacle avoidance were enough. In fact, since its establishment in 2008, Chery has had a collision laboratory capable of reproducing traffic accidents, making it the fourth in the world.
In terms of side impact, Xingtu not only complies with the current offset impact requirements of 50km/h, but has actually developed it according to 60km/h and verified it in advance with more stringent requirements. In the C-NCAP test of the new version of the regulations, the ground clearance was 50 mm higher than the European star rating. According to Liu Yuguang, chief engineer of the National Car Quality Supervision and Inspection Center, "Don't underestimate the height of 50 mm. You can imagine that if the car that hit it is relatively tall, it will be difficult for the sill beam of the hit car to function."
Why is the test height of C-NCAP higher than that in Europe? Liu Yuguang explained that this is consistent with the situation of China's road vehicles. "The number of SUVs in China is very high globally, so when a collision occurs in simulated road traffic accidents in China, the average height above the ground is higher than High in Europe, which is also a very important factor why the 2018 version of C-NCAP is more stringent than European standards in terms of side collisions.”
In addition, Xingtu has also undergone strict pillar impact tests. In fact, the side pillars. The collision conditions are also very harsh. Both the front door and the rear door side collision conditions are verified accordingly. This is a plus point in the US collision requirements and European collision requirements. That is to say, you are only allowed to do this side pillar collision if you have a relatively high score in completing the conventional side collision to see if the car has better ability to prevent pillar collisions.
In addition to the passive safety design and materials in place, in terms of active safety, Xingtu TXL adopts ADAS driving assistance equipment and Bosch’s latest ESP?9.3 system, which is committed to making the best possible decisions before the vehicle is involved in an accident. Quick response.
In Liu Yuguang's view, in the context of more and more active safety configurations in cars in the past two years, consumers should pay the same attention to active safety configurations when choosing cars as they did before to ESP. The more active safety configurations such as AEB are installed in models, the more The more advantageous it is.
