In order to allay the concerns of users, the ideal car released the "upgrade of the ideal L9 air spring quality assurance scheme" on the app. Ideal Automobile official said, "recently, an ideal L9 store test drive high-speed impact on the road pit, causing air leakage damage to the right front air spring, bringing users doubts about the quality and durability of the air spring." Out of confidence in product quality and to allay users' concerns about air springs, we decided to upgrade the ideal L9 air spring (including air spring body, air pump, gas storage tank) warranty scheme to the same 8 years or 160000 kilometers as the Sandian system, and the used car transaction does not affect the validity period of the warranty. "
According to the CCTV report, an ideal L9 suspension problem, the vehicle left front wheel trapped in the body, can not drive normally, suspected of vehicle air suspension failure. According to the group chat, it is suspected that an emergency brake caused the air suspension of the ideal L9 to break.
In this regard, the ideal car responded: "the test driving in Chongqing is to rush through a pit with a depth of 20 cm at a speed of 90 km / h, resulting in damage to the buffer ring inside the empty spring." Because of the supply problem, some of our test drivers have used the buffer ring in the trial production stage. Although the trial version meets the safety standards, it will fail occasionally under large impact conditions. The buffer ring strength of the actual mass production version is 2.5 times that of the trial version, and there will be no problem in the face of greater impact. " In addition, ideal said, "this failure is a case of non-mass-produced parts, which has been identified and will be resolved on the final mass-produced body."
However, such an explanation is not convincing. Public data show that the minimum ground clearance of the ideal L9 is 176mm, which is smaller than the "20cm pit" of the ideal car, which means that the ideal L9 may hit the chassis when passing through the pit, while the speed of 90km / h is over the "20cm pit", the tire does not explode and the rim is not deformed, but the buffer ring inside the empty spring is damaged, which is not in line with physical common sense at all.
In addition, Hu Zhengnan, former director of Geely Research Institute, said: a pit with a speed of more than 20 centimeters per hour is not quite in line with the actual situation. In general, the clearance between the ground of a vehicle is less than 20 centimeters, and normal people will not travel at a high speed toward a pit of 20 centimeters. If this is the case, it can only be said that your family's tires are really great. In addition, Hu Zhengnan also questioned the so-called "trial parts used for trial driving, and the strength of the produced parts is 2.5 times that of the ideal car." Hu Zhengnan believes that a car from a prototype to a mass production car has to go through TT (tooling testing), PP (trial production), VP (prototype vehicle confirmation), and MP (mass production) stages, and each stage of the car has a corresponding use scene.
It is understood that the ideal L9 is the second production car of the ideal car, which officially went on sale on June 21 with a price of 459800 yuan. It is known as "the best household flagship SUV within 5 million". At the launch of the new car, ideal car founder Li Xiang said: "the ideal L9 suspension uses a front double-arm and rear five-link structure, providing flagship driving performance and ride comfort, coupled with millisecond response CDC damping system, even compared with Curinan, we are not afraid." Li Xiang even said, "in order to feel the suspension system, he deliberately goes home an extra 20 kilometers from work every day."
As a matter of fact, someone did compare him to Curinan. Chen Zhen, a well-known car critic, said after a test drive of the ideal L9: "the L9 is obviously a comfortable adjustment style. Compared with my Curinan, it lacks a little sense of stability and weight, but the overall chassis is very comfortable." In addition, Yan Chuang, a well-known car critic, said: "when the ideal L9 crosses a bumpy road, the chassis has a good texture. I was pleasantly surprised by the steering of the car and the delicate feedback of the chassis. The support of the chassis for the mountain road, for the daily filtering of small bumps on the road, is a good performance."
Official data show that the ideal L9 suspension system is an adaptive air suspension system. On the "spring" assembly of the system, the ideal L9 uses an "air spring" rather than a traditional spring, and its principle is to fill the pressure cylinder with inert gas so that the pressure in the cavity is higher than the atmospheric pressure. the telescopic movement is realized by using the pressure difference caused by the cross-sectional area of the piston rod is smaller than that of the piston. It is understood that the advantage of "air spring" is to ensure that the suspension has a stable compression stroke in the case of multiple passengers, and can dynamically adjust the height of the chassis. At present, there are three "air spring" suppliers for the ideal L9, including Baolong Technology.
Judging from the response of the ideal car, directly arranging an 8-year or 160000-kilometer warranty for the air spring (including the air spring body, air pump, and gas storage tank) is more convincing than the public relations response, and from the feedback of users, it can be regarded as a comeback. However, the ideal L9 incident will still affect the ideal brand. After all, Li Xiang once boasted that "L9 is the best SUV within 5 million" and "hanging Curinan, Mercedes-Benz and BMW". In fact, this kind of low-level problem should not occur. Although officials have not admitted that there are product defects, they will still leave a shadow on users.
High hardware configuration does not necessarily mean high quality. Compared with traditional car brands, the reason why New Power cars can attract more attention is mainly to rely on stacking materials. The ideal L9 matches all the air suspension, CDC, front double-arm and rear multi-connecting rods, which is known as "the best household flagship SUV within 5 million" and "is not afraid even compared with Curinan", but there is still a problem, which shows the problem. In other words, a high configuration also needs to match a high-quality provisioning level.
