· Haval H4 first publicly challenged the US IIHS top pressure test for excellent evaluation

<

On March 25th, Haval's new compact SUV Haval H4 was officially launched. Debuted as the focus, on the day of the listing, Haval H4 first publicly carried out the rigorous US IIHS top pressure test, and passed the 4.56 times stress test, which proved its outstanding safety performance with excellent results!

What is the IIHS pressure test?

IIHS is the abbreviation of the Insurance Institute for Highway Safety. It is the authoritative vehicle safety data testing and statistical agency in the United States. The US IIHS test consists of five major crash test items, 25% small overlap collision, 40% frontal offset collision, side impact, roof strength test, whipping test, and four grades (Good Excellent, Acceptable Good, Marginal Qualified, Poor) Poor). Among them, the US IIHS roof strength test has the most stringent requirements in the world. IIHS introduced this project in 2009 to simulate the protection of occupants when the vehicle rolls over. As the most demanding test for vehicle safety in automotive top pressure testing, it is not easy to get an excellent rating in this test.

Why should Haval H4 openly carry out the IIHS top pressure test?

The results of the IIHS survey show that when the roof is subjected to a pressure of 4 times the weight of the vehicle, the fatal damage in the rollover accident is reduced by 50%. The public safety test was conducted with real test data to verify the safety of existing vehicles, which in turn promoted the safety of Harvard's future vehicles. Dare to use such a rigorous test to verify the safety of the vehicle, and also to see the Harvard brand's confidence in the safety performance of H4.

Confidence stems from the tough strength of the product itself. The Haval H4 uses the 3DP body safety design concept to achieve all-round protection from the three dimensions of “occupants, pedestrians, and vehicles”. Haval H4 adopts high-strength and high-efficiency energy-absorbing integrated safety body design. It applies a large number of high-strength steel and thermoformed steel, high-strength side column, with annular envelope skeleton structure and laser welding technology for safety performance requirements. The key parts are reinforced to create a high-strength safety “barrier” for the user. In the design of roof pressure compression safety, Haval H4 designed the complete force transmission channel of A-pillar, B-pillar, C-pillar and top cover beam, and evaluated according to the US IIHS roof static pressure requirement, achieving Good grade. The results of this top pressure test are the best verification of its excellent roof pressure capacity.

What are the IIHS test methods and standards?

The roof strength test method is to make the metal platen hit the side surface of the single side of the roof at a certain speed, and then based on the ratio of the peak load measured in the range of 127 mm of the platen displacement to the vehicle weight (the whole vehicle quality state) during the test. (SWR) for evaluation;

The roof strength rating is divided into four levels: excellent, good, average, and poor. The SWR limits are as follows:

SWR≥4.00 is excellent (corresponding to “G” in IIHS standard), 4.00≥SWR≥3.25 is good (corresponding to “A” in IIHS standard), 3.25≥SWR≥2.50 is general (corresponding to “M” in IIHS standard), SWR<2.50 Poor (corresponding to "P" in the IIHS standard).

Passed a 4.56 times pressure test to set a new benchmark for autonomous compact SUV
At the test site, the staff rigidly fixed a Haval H4 to a rigid level, closing all windows, closing and locking all doors. The loading device moves down in a direction perpendicular to the lower surface until the load reaches the official size. More than 300 media from all over the country witnessed the test and looked forward to the final results of Haval H4!

The IIHS top pressure test results are more than 4 times the highest weight, and the Haval H4 has passed the 4.56 times stress test with its high-strength body and excellent roof compression safety technology! As a newcomer to the Harvard Legion, Haval H4 proved himself with an outstanding record!

It is worth mentioning that Harvard also carried out the pyramidal test at the scene of the H4 launch conference. On the scene, six Haval H4s were displayed in the form of a pyramid. The bottom vehicle was under pressure of more than 9 tons. The Haval H4 was extremely visually impactful. The way, once again proves its strong safety genes and excellent safety body design, it is strongly branded with "high security".

Strict production standards cast a safety strength SUV
Passing the most stringent IIHS top pressure test with excellent results not only proves the outstanding safety performance of Haval H4, but also confirms the strength of Haval brand in manufacturing high safety SUV. Since the development of the new car, Great Wall Motor has injected the concept of R&D safety, adopting the world's most stringent technical standards and safety collision evaluation system, and designing and developing products according to EU standards. While perfectly inheriting the core safety technology of Haval, the strict control of the quality of H4 products by the manufacturers is also “cracking”. In the introduction of active and passive safety configuration, the world's top security suppliers such as Bosch, Autoliv and the mainland are selected. The car provides a more powerful quality assurance, providing users with safer and more reliable products.

With the upgrading of the automobile consumer market, car safety has become one of the most concerned factors for consumers to buy a car. As a self-owned brand with the concept of safe car manufacturing in China, it has already been ahead of other car companies and is at the forefront of the industry. As the latest strategic model of the Haval brand, in fact, the Haval H4 not only inherits the high safety performance of Haval products, but also maintains the excellent performance in power, control and configuration. It is a powerful SUV with obvious competitive advantages. It is believed that with the solid product strength, the Haval H4, which has been officially listed, can bring consumers a new choice of car purchase.
