Project Background: From Initial Procurement to Requirement Iteration — The Ford Transit V362 service vehicle procurement project for a municipal sanitation department in Qujing (hereinafter referred to as 'the client') originated from road inspection and emergency repair requirements at the end of 2023. Initially, five Ford Transit V362 chassis-based service vehicles were procured, primarily for routine inspections, equipment transportation, and minor repairs. However, after six months of actual operation, the client identified several critical issues: insufficient cargo compartment space, unable to accommodate large-scale repair tools simultaneously; limited chassis load capacity, leading to rear axle wear due to frequent operations; and higher-than-expected fuel consumption, resulting in operational costs exceeding budget. These 'pain points' prompted the client to launch a second procurement round in 2024, with requirements upgraded from 'basic mobility' to 'professional emergency service vehicles', demanding enhanced power output, greater cargo capacity, and lower operating costs. Following market research and a formal tender process, the client ultimately selected Chengli Special Purpose Vehicle Co., Ltd.’s upgraded service vehicle — retaining the Ford Transit V362 chassis but fully customizing the bodywork to meet the new requirements. This article details this 'requirement-iteration' procurement case and analyzes key aspects of the solution. First-round Procurement Experience: Ford Transit V362 Base Model The initial batch of five vehicles utilized the Ford Transit V362 chassis, equipped with a 2.0L turbo-diesel engine and a 5-speed manual transmission. Standard configurations included dual-row seating (accommodating up to five passengers), an open rear cargo area (approx. 3.5 m³ volume), and basic lighting and power outlets. Unit price was approximately RMB 120,000 (per publicly available tender data), with total budget capped at RMB 687,000. Identified Shortcomings During Operation: • Space Limitations: Cargo compartment height was only 1.2 meters, preventing upright storage of ladders, generators, and other large equipment — requiring disassembly for transport and reducing repair efficiency. • Load Capacity Issues: Rated rear axle payload was merely 1.2 tons; loading repair tools and spare parts frequently resulted in overloading, increasing shock absorber failure rates. • High Fuel Consumption: Actual combined fuel consumption reached ~10.5 L/100 km (fully loaded), exceeding the target of 8 L/100 km and raising annual operating costs by ~RMB 12,000 per vehicle. • Substandard Modifications: Aftermarket-installed racks and cabinets lacked secure mounting, causing severe rattling during transit, and dedicated tool anchoring points were absent. After six months, the client reported: 'The vehicles perform adequately on flat roads, but clearly lack sufficient capability during mountain-area inspections or urgent repair scenarios.' This prompted a comprehensive reassessment of procurement requirements. Enhanced Requirements: Key Specifications for the Second-round 'Upgraded' Procurement In May 2024, the client issued its second tender, with core requirements significantly upgraded: • Chassis: Retain Ford Transit V362 platform, but require reinforced rear axle (rated payload ≥1.8 tons) and a 6-speed automatic transmission (to reduce driver fatigue). • Bodywork: Tiered cargo compartment design — lower tier for securing heavy equipment such as generators and pumps (max. load capacity: 1.2 tons); upper tier enabling upright ladder storage (height ≥1.8 meters), plus rotating turntables and locking mechanisms. • Power System: Integration of a 100Ah lithium battery pack and a 3,000W pure sine-wave inverter, supporting grid connection for on-site emergency power supply. • Temperature Control & Storage
