Government Procurement Case and Bid-winning Solution Analysis of the Ford New Generation V348 Service Vehicle in Zhuhai. In this coastal city, the hot-humid climate and frequent rainy season impose stringent requirements on the weather resistance and operational efficiency of municipal sanitation vehicles. A municipal sanitation department recently completed the procurement of a batch of service vehicles, ultimately selecting Chengli’s service vehicle built on the Ford New Generation V348 chassis. Following delivery, daily inspection and emergency response capabilities improved significantly. This article reconstructs the case—from procurement background and solution alignment to user feedback—to provide reference for industry peers. I. Pain Points of Aging Equipment: Performance Bottlenecks in Hot-Humid Environments. The department’s existing fleet of service vehicles had been in operation for many years and faced three core issues: Severe Body Corrosion: Zhuhai’s high-salinity fog and high humidity cause extensive corrosion on standard steel bodies within just 2–3 years—not only degrading appearance but also compromising structural integrity and driving up maintenance costs. Aging and Failure of Sealing Components: Rubber seals on doors, windows, and inspection hatches accelerate aging under alternating hot-humid conditions; during the rainy season, water and dust ingress into the cabin impair equipment functionality. Frequent Failures under High-Load Operation: During the rainy season, inspections and emergency tasks increase sharply. Aging vehicles—due to insufficient engine cooling capacity and low air-conditioning refrigeration efficiency—commonly break down after four consecutive hours of operation, reducing fleet availability. According to records provided by the department, annual maintenance costs for the old vehicles have approached 30% of their residual value, with failure rates increasing by over 40% during the rainy season—making replacement urgent. II. New Requirements Research Process: From Tendering to On-site Inspection. In Q3 2025, the department launched its procurement process, with a budget capped at approximately RMB 402,000 (per publicly available tender information), aiming to acquire two multi-functional service vehicles. Key requirements included a reliable chassis, body modifications suited to hot-humid environments, and rapid response capability. The research team evaluated multiple manufacturers, focusing on the following criteria: Chassis Performance: The Ford New Generation V348 chassis is renowned for high reliability and low fuel consumption—ideal for urban road conditions. Anti-Corrosion Treatment: Must employ electrophoretic coating or hot-dip galvanization to ensure no visible corrosion for at least five years. Seal Durability: Seals must be made from silicone rubber or fluororubber, rated for temperatures from −40°C to +150°C, and certified via humid-heat aging tests. Modification Flexibility: Must include pre-installed interfaces for mounting mobile communications systems, emergency lighting, and other equipment. During an on-site visit to Chengli Special Purpose Vehicle Co., Ltd. (No. 1 Chengli Avenue, Economic Development Zone, Suizhou City, Hubei Province), the team discovered that Chengli’s southern-market-customized solutions had passed multiple hot-humid environmental tests. Chengli Sales Manager Zhang Yue (Tel: ) presented prior projects—including water-sprinkling and mist-cannon vehicle deployments in Guangdong industrial parks—all optimized for southern climates with enhanced anti-corrosion and sealing designs. III. Chengli’s Solution Match: Customized Modifications of the Ford New Generation V348 Service Vehicle. Based on the department’s requirements, Chengli proposed a modification solution built on the Ford New Generation V348 chassis, featuring the following key attributes: Comparison Item | Legacy Aging Vehicles | Chengli Ford New Generation V348 Service Vehicle
