China News Service, July 20th (Zhongxin Finance and Economics Ge Cheng) The ideal car was "spoiled" because of the suspension problem.

　　Recently, a topic related to "Break of the Air Suspension of the Ideal Test Drive's Emergency Brake" appeared on Weibo's hot search.

This topical product, which is self-proclaimed as "the strongest family SUV within 5 million", was questioned again when it was about to be delivered.

Ideal response to "suspension fracture" questioned

　　At the Lixiang L9 press conference about a month ago, Li Xiang, CEO of Lixiang Auto, said that everyone is welcome to bring their friends and let them drive the top SUVs such as Cullinan, Mercedes-Benz GLS Maybach, Land Rover Range Rover and BMW X7. For a test drive, "let everyone take a look and see if the ideal L9 is worthy of the title of the best family SUV within 5 million."

　　Shortly after these remarks were issued, due to the "suspension break" storm, the Ideal L9 was immediately pushed to the "cusp" of public opinion.

According to a number of media reports, the ideal L9 in the accident suffered a "bang" after experiencing a sudden brake, and the front suspension broke.

　　In response, Li Auto responded that the accident "was caused by a test drive in Chongqing that rushed through a deep pit of more than 20 cm at a speed of 90 km/h, resulting in damage to the buffer ring inside the air spring."

　　Li Auto also stated that due to supply problems, some test cars use the buffer ring in the trial production stage.

Although the trial version meets the safety standards, it will occasionally fail under large shock conditions.

The strength of the buffer ring of the actual production version is 2.5 times that of the trial version, and there will be no problem in the face of greater impact.

　　However, people in the industry have also raised doubts about the ideal car.

Hu Zhengnan, the former president of Geely Research Institute and a partner of Shunwei Capital Investment, said on social media, "'The pit with a speed of 20 cm per hour at 90 km/h' is not in line with the actual situation. The ground clearance of ordinary vehicles is not 20 cm. .And normal people don't travel at high speed in the pit of 20 cm. And if this is the case, then I can only say that your tires are awesome. In this condition, the tires did not burst and only blew up in the air. a word."

　　In addition, Hu Zhengnan also questioned the claim that the ideal car was a "trial product", he said, "In addition, the test drive uses a trial product, the strength of the mass production part is 2.5 times, and the performance of the trial product is different. You make it what?"

　　After the incident, Li Auto revised the relevant warranty policy and decided to upgrade the Li Li L9 air spring (including the air spring body, air pump, and air storage tank) to the same 8 years or 160,000 kilometers as the three electric system. , and the used car transaction does not affect the validity period of the warranty.

　　However, for the ideal new warranty policy, some consumers said that they should be "wait and see" and "see it."

Chassis Parts "Material War"

　　A few days before the accident of the sudden brake air suspension breakage of the ideal test car, the ideal L9 had caused a material dispute over the lower swing arm of the chassis on social media.

　　In the message of Li Xiang, CEO of Ideal Motors, sharing his views on car suspension, some netizens mentioned that "My friends found that the suspension of Ideal L9 is obviously made of iron, and the manufacturer insisted that the surface be painted with aluminum alloy. It made him feel very puzzled."

　　In response, Li Xiang responded, "No one stipulates that cast iron must be coated with black paint, and cast iron is not black. The large horizontal swing arm of the rear five-link of the ideal L9 adopts a much more expensive anti-corrosion coating, which has an anti-corrosion effect. More than 200% better, the cost is higher. The color of the anti-corrosion coating is silver, and we never said it was aluminum, and aluminum is not a high-end thing."

　　Li Xiang also said, "It is strongly recommended that netizens who think that aluminum must be better than steel and iron, remove the main steel structure of their house and replace them all with aluminum, which is absolutely safe and scientific! It's not a concept of stealing, but to make what you think in your mind, what you say in your mouth, what you do in action, and what you really do consistent, so that knowledge and action are unified. Where aluminum is used in a car, steel and Iron, it is not decided by slapping the head and typing on the keyboard." However, this reply has now been deleted.

　　Li Xiang's remarks immediately caused controversy. Some netizens said, "It's obviously two things. Can building materials and vehicle materials be the same thing?"

　　An automotive chassis engineer told Zhongxin Finance that compared with steel swing arms, aluminum materials are lighter and more expensive. It can effectively reduce the unsprung mass of the car, which can correspondingly improve handling.

"However, it depends on the adjustment. The chassis of the car is an overall structure, and the specific model needs to be analyzed in detail." (End)
