"Many car brands are still experiencing rust issues. Technically speaking, corrosion and rust prevention are not difficult. However, some brands may not implement these measures thoroughly due to cost considerations. The SAIC Volkswagen ID.ERA 5S uses 30% hot-formed steel, ensuring effective corrosion protection." On August 11, Fu Qiang, Deputy General Manager of Sales and Marketing at SAIC Volkswagen Automotive Co., Ltd. and General Manager of Shanghai SAIC Volkswagen Automotive Sales Co., Ltd., addressed the current quality control issues in vehicle manufacturing at the product launch for the SAIC Volkswagen ID.ERA 5S. During the event, live guests revealed that the content of hot-formed steel in the body of some models has dropped to as low as 18%. "Many car brands promote televisions, refrigerators, and sofas, but its also important to invest effort in areas that are not visible," said Li Jun, Executive Director of Brand Marketing at SAIC Volkswagen Automotive Co., Ltd. Fu Qiang noted that under intensified price competition in the industry and pressure to control costs, many models may cut back on investments in aspects such as body materials and durable protection that consumers may find difficult to perceive intuitively. However, in the family sedan market, safety is the most important foundation.
