[YesAuto technology] Geely Borui, which was led by the former Volvo design director Peter Hobury, to complete the exterior design, has received unanimous praise from domestic consumers for its appearance since its inception. Obviously, after acquiring the Nordic brand, Geely started With more ability and confidence to carry out positive research and development of models, and the results are really good. In addition to more advanced design concepts, what else can Geely gain from this acquisition? Very simple, it must be safety, because the Volvo brand is still unique in safety, so Borui’s safety should have been “true” by Volvo.
Borui’s high-end models are equipped with most of the active safety configurations currently available on the market, including ACC system, blind spot monitoring system, urban pre-collision safety system, yaw warning system and automatic parking system. In addition, in traditional For the electronic stability control system, Geely has also conducted in-depth cooperation with the international component giant Bosch. ESP, ABS and TCS all use the latest version of Bosch's system and have passed relevant Bosch tests.
Geely Borui engineers frankly said that Borui has indeed learned a lot from Volvo in terms of active safety technology. For example, the city pre-collision safety system and the blind spot monitoring system are derived from Volvo's City Safety system. With the continuous development and maturity of technology, Geely will work with Volvo to further improve active safety technology.
In terms of car body structure, Borui adopts a cage car body structure, which can ensure that in the event of an impact, the body structure can effectively disperse and absorb the impact energy, thereby maintaining the integrity of the passenger compartment and maintaining a living space for the occupants. In addition, Borui ranks first in the application of high-strength steel in Geely's models . 58% of the steel in the body structure is high-strength steel. Especially in the A-pillar, B-pillar and some beam structures, the yield strength is also used. Hot-formed ultra-high-strength steel of 1400MPa or more. Of course, during the design and development of the body structure, the Borui project also received technical support and help from Volvo, so it can be said that Borui has incorporated Volvo's safety genes.
In terms of restraint systems, Geely has launched a comprehensive cooperation with Autoliv, a well-known supplier in the industry. Both the seat belt system and the airbag system come from Autoliv. It is worth mentioning that the high-end Borui models are equipped with 7 airbags, of which the driver's knee airbag is less equipped with models of the same price and the same level.
Geely engineers said that Borui’s passive safety design goals would be slightly higher than the current collision rules, and the EU’s E-NCAP standards were taken into consideration at the beginning of the design. In addition, although there is no plan to enter the North American market, Geely still conducted a small overlap collision test similar to the IIHS 25% offset collision test for Borui. Therefore, in the face of the 2015 version of the C-NCAP test standard, Borui's engineering developers seemed confident.
-Borui's C-NCAP test
Speaking of the C-NCAP test, we are very fortunate to witness Borui's 100% frontal rigid barrier crash test and side crash test. During a collision with a 100% frontal rigid barrier, the energy-absorbing area at the front of the car body completely collapsed, absorbing the energy of the collision to the maximum, so the wheels did not have too much intrusion displacement backwards, and the front tires could also maintain Intact, indicating that the front energy absorption effect is still relatively good. The aluminum alloy anti-collision beam transmits the energy of the front impact to the cage body structure through the energy absorbing box and the longitudinal beam, so that the energy is effectively dispersed and the passenger compartment structure remains intact.
In the side impact test, Geely Borui's passenger compartment can still remain relatively intact after being impacted. This is mainly due to the structural design of the cage body and the application of high-strength steel in key parts. In addition, the side airbags and air curtains equipped with high-end models will theoretically also play a role in the test.
Due to the test schedule, we have not seen Borui's performance in several other projects, and the official final results of C-NCAP will also be officially announced in the future. Only from the 100% frontal rigid barrier crash test site, Borui did not show any obvious deficiencies when facing the existing crash standards, and we will report on the overall performance of this model in more detail in the future. .
to sum up:
Borui 2015 1.8T flagship
With monthly sales of more than 4,000 units, Geely Borui has become the most successful medium-sized sedan of a Chinese brand in history. If all its current success is attributed to its beautiful appearance, it is obviously unfair. After successfully acquiring Volvo's passenger car business, Geely, which is still slightly naive in terms of technology development, has obviously obtained a lot of useful resources, including the safety technology that the Swedish brand has relied on for decades.
Since the acquisition of Volvo in 2010, Geely has signed a framework agreement for strategic cooperation with each other. Since then, the two parties have begun to send engineers to each other's teams for technical exchanges. Since then, many of Volvo's domestic tests have been completed in Geely's laboratories, and some of Geely's engineers have also made a special trip to Volvo's headquarters in Sweden to study and jointly develop technology with its engineering team. Geely Borui, which was born after digesting and assimilating foreign technologies, is clearly expected to perform in terms of safety. In terms of the active and passive safety configuration of the vehicle, we have seen its self-confident capital, and the C-NCAP test will also become a touchstone for verifying the safety level of Borui.
