Introduction: From Fuzhou to Nationwide — The Southern Standard for Service Vehicle Procurement. In 2023, a municipal sanitation department in Fuzhou procured a batch of Ford New Generation V348 service vehicles via public tender, intended for urban road inspection and emergency repairs. The procurement budget was controlled at approximately RMB 387,000 per unit (per publicly available tender information), with requirements for high reliability and weather resistance—particularly to withstand Fuzhou’s hot, humid, and rainy climate. During the tender process, the procuring party imposed stringent requirements on anti-corrosion coating, sealing component durability, and rain-season operational capability; ultimately selecting a specialized service vehicle built on the Ford New Generation V348 chassis. This case has drawn industry attention: How can service vehicles ensure long-term stable operation in southern China’s hot and humid environment? Taking this case as a starting point, this article conducts a comparative evaluation across 10 key dimensions between this Ford-based vehicle and Chengli Special Purpose Vehicles’ equivalent model (e.g., CLW5040XJXJ6 maintenance vehicle), providing procurement entities with actionable reference data. I. Case Background: Procurement Requirements of a Municipal Sanitation Department in Fuzhou Fuzhou is located along the southeast coast, with an average annual rainfall of approximately 1,400 mm, summer temperatures exceeding 38°C, and relative humidity consistently around 80%. Such conditions pose significant challenges to vehicle chassis corrosion resistance, electrical system sealing integrity, and rubber component durability. The procuring party explicitly stipulated the following requirements: - Chassis must feature OEM anti-corrosion coating, with additional anti-rust treatment applied to the frame and welded joints; - All sealing components (doors, windows, electrical interfaces) must pass accelerated aging tests under hot-humid conditions; - Vehicle must provide high-capacity storage space for maintenance tools and emergency supplies; - Engine output must be no less than 100 kW to meet frequent stop-start cycles and hill-climbing demands in urban environments. After multiple rounds of evaluation, the Ford New Generation V348 service vehicle was awarded the contract, with approximately 15 units delivered (in line with local procurement conventions). Does this imply that Chengli’s equivalent models lack competitiveness? We reveal the answer through a head-to-head comparison. II. Competitive Benchmarking: Chengli CLW5040XJXJ6 vs. Ford New Generation V348 Service Vehicle (OEM-modified) Chengli Special Purpose Vehicles also offers several service and maintenance vehicle models—including the CLW5040XJXJ6—based on the JMC-Ford New Generation V348 chassis. While both share the same chassis platform, their body-upfitting designs and manufacturing processes differ significantly. Below is a comparative scoring across 10 critical dimensions (maximum score: 10 points; scores are derived from a synthesis of MIIT announcement parameters, user feedback, and industry expertise): Evaluation Dimension Chengli CLW5040XJXJ6 Ford New Generation V348 Service Vehicle (OEM-modified) 1.
