The Economic Daily published an article pointing out that recently, the topic of express cars has hit the headlines and has become a hot topic of continuous discussion in the automobile industry. Behind the buzz, on the one hand, hundreds of new cars were launched in the first half of this year; on the other hand, the cost of rapid delivery may be a lack of necessary safety verification and durability tests, and its safety hazards have become public concerns. In the midst of the transformation of new energy vehicles, vehicle building methods are improving. The express car dispute is the industry's reflection on whether quality has given way to speed in current competition, reflecting the unprecedented competitive pressure brought about by market segmentation behind the intensive launch of a large number of new cars. According to industry insiders, if a new car wants to enter the market, it still needs to complete special verification. For example, to verify tightness, it is necessary to use a specific machine to simulate a heavy rainfall environment to check whether the vehicle's quality in terms of water seeping, corrosion, and gaps has passed. Also, for environmental and durability verification, it is necessary to carry out three-level calibration verification, full-scene durability road test, and salt spray corrosion verification. This test requires a minimum of two winters and two summers, and long-distance road tests of tens of thousands of kilometers to simulate the intensity of use throughout the entire life cycle of the vehicle and verify the quality of the chassis, body, and in-vehicle accessories. To complete the full verification process described above, the vehicle requires actual running time and sufficient mileage. The total time required is 12 to 18 months. Some models rely on mature platform reuse technology to complete some virtual verification in advance through digital simulation, which can appropriately reduce the length of some of the steps, but reliability verification steps such as the core actual vehicle's “three highs” and durability cannot be drastically reduced; otherwise, the product safety threshold will be lowered.
