On October 13, 2017, the most rigorous open rollover test for a Chinese SUV was carried out in the Real Car Collision Laboratory of the China Automotive Technology and Research Center (CATARC) in Tianjin for the first time. New Haval H6, meeting all the indicators, manifests its superior safety performance as a SUV leader.
Compared with tests in Europe and the United States, this test is more rigorous in standards, more comprehensive in content, and more adaptable to roads all over the world. The test, attracting extraordinary attention of the public, was attended by hundreds of people including industrial experts, media and consumers who witnessed the test of New Haval H6 and result releasing on site.
CATARC initiated its study on rollover associated safety of the Chinese domestic brand automobiles in 2015. The ground of test is set as asphalt concrete pavement according to the condition of real highway situations. The test standards are more rigorous and advanced than those in Europe and the United States. The test features faster initial rollover speed of 50 km/h and increasing mass with one more dummy added, resulting in a more intense rollover. The test becomes more comprehensive with another H3 5% dummy (Short adult female figure) added on the passenger seat. In this way, it is possible to assess the safety performance of the automobile for passengers of different body types and locations.
The test car is randomly selected from commercial automobiles of mass production. At the test site, the New Haval H6 was pushed at a speed of 49.8 km/h by the rolling machine, and then it rolled for three and a half rounds on the asphalt concrete pavement specially laid.
After the test, as suggested by the final results released by CATARC, the New Haval H6 performed well in the four tests. As the body structure remains complete and the constraint system plays its role rapidly and effectively, all parts of the dummy remain within the cabin. With damage probability of such key parts of the passengers as head and neck below 10%, and rescue after an accident will not be hindered.
Body structure serves as the first guard for rollover associated safety of a vehicle. The vehicle model with panoramic sunroof, one of the most popular ones in the Chinese market, is selected for the test. Although it is widely thought that a sunroof is regarded as a weakness by lowering body strength, the high strength steel body of the New Haval H6 with laser welding technology remains complete in the test. Doors kept closed and no visible crush or bending is found in the A/pillar and B/pillar.
Constraint system plays a major role in fixing and protecting passengers in the rollover process. In the rollover test of the Haval H6, all the body parts of the two dummies remain within the cabin, and seats have showed no failure including reverse, overturn and slip; the seat belt warning device has worked to constraint passengers on the seat effectively in the moment when the automobile hit the ground; the air curtain and side airbag for both the driver and assistant driver have been inflated in time to prevent the damage hurt caused by the strike between head and body and the automobile rigid structure.
Passenger's damage value shows the damage probability. As shown by the data collected from the dummy, the head and neck damage probability for the driver is 0.3% and 5.3% respectively, while those for the assistant driver are 0.3% and 6.9%. The risk is low, proving that the new Haval H6 is effective in protecting its passengers.
As to the rescue work after rollover, all the doors of the New Haval H6 can be opened without hassle. The constraint system is not locked, the seat belt can be opened normally, and there is no sign of fuel tank leakage, which prevents a fire risk after rollover.
The core value of Haval, putting safety first, is important in making it the choice for nearly 4 million customers. The vice president of Great Wall Motor, Samuel Chen said at the test site that: "We have applied the most rigorous technological standard and safety collision evaluation system meeting the global market's requirement, to build Haval, the most valuable SUV brand in the world".
Haval's emphasis on safety can be told from its resources input. It has invested RMB 5 billion around (R10 billion) to build the largest world-class automobile R&D technological center in China, with the construction area of 260,000 m2. Also, Great Wall has formed the 3D safety design concept of "safety of passengers, pedestrians and body structure" since 2010, established the safety R&D technological system based on the scientific combination of virtual design and experimental validation, made innovative use of collision safety performance development process. Targeted on the New Haval H6, over 80 safety conditions covering passengers, pedestrians and body structure have been taken into consideration and more than 5000 virtual simulation analyses have been conducted, which have helped the new Haval H6 to reach the goal of safety performance in the first round model collision test.
The Great Wall Motor's current safety test can meet the requirements in both China and the EU, even part of the laws and regulations of the US and NCAP. In the New Haval H6, a new "armor safety system" is introduced. In addition, it is also equipped with high-performance four-wheel ventilated brake disc rarely seen in the same class model, as well as the Bosch 9th generation ESP. At the same time, a series of safety facilities are equipped like ABS+EBD, HDC, EBA, visible right front blind area and SAHR.
Haval H6 is a popular car, and with its cumulative sales having surpassed 2 million units in September. Its great market share has not only revitalized China's SUV market as well as the passenger car market, but also attracted the world's attention to China's manufacturing as an independent brand in the SUV field.
