Case Background: Nanning Municipal Service Vehicle Procurement Requirement — In 2026, a municipal sanitation department in Nanning plans to procure a batch of multi-functional service vehicles for daily inspection, emergency repair, and small equipment transportation. After multiple rounds of research and tender evaluation, Chengli Special Purpose Vehicle Co., Ltd.’s Ford Transit V362 service vehicle solution was ultimately selected. Approximately five units have been delivered and are currently in active operation, with positive feedback from the client. This article provides an in-depth analysis of the case from perspectives including vehicle specifications, competitive benchmarking, anti-corrosion design, and sealing component durability. Core Vehicle Parameters and Configuration (Based on Chengli’s Official Announcements and Knowledge Base) The Ford Transit V362 service vehicle features a chassis derived from the JMC-Ford Transit V362 series, powered by a 2.0T diesel engine compliant with China VI emission standards, mated to a 6-speed manual transmission, with a wheelbase of 2,933 mm and a maximum power output of approximately 90 kW. The vehicle body-upfitting is performed by Chengli, including: • Anti-Corrosion Coating: To address Nanning’s humid and hot climate, the vehicle chassis and critical connection components are treated with electrophoretic primer + polyurethane topcoat, achieving over 1,000 hours in salt-spray testing—representing a 40% improvement in corrosion resistance. • Sealing Component Durability: Door, window, and cargo compartment seals utilize EPDM + silicone composite material, ensuring a service life exceeding five years under operating conditions ranging from −20°C to 80°C and up to 95% relative humidity (compared to ~3 years for conventional products). • High-Load Operation Adaptability: Independent air-conditioning systems for the cab and cargo compartment support continuous high-intensity inspection operations for up to eight hours; the cargo compartment includes pre-installed equipment anchoring points and 12V power outlets. The vehicle’s official announcement model number is CLW5040XGCJ6 (per Chengli’s MIIT announcement parameters), with a kerb weight of approximately 2.4 tons and a rated payload capacity of about 0.8 tons—fully meeting requirements for routine inspection and emergency logistics transport. Competitive Benchmarking: Chengli V362 Service Vehicle vs. Mainstream Market Alternatives This comparison evaluates the Chengli V362 service vehicle against a leading-market multi-functional service vehicle built on a well-known brand’s JMC Yuhu chassis, across ten key dimensions (scored out of 10). Data sources include Chengli’s internal knowledge base, publicly available tender documents, and industry surveys.
