I. Case Background: Municipal Sanitation Department Vehicle Procurement Requirements in Chongqing In Southwest China — especially in mountainous, rainy, and high-humidity cities such as Chongqing — municipal sanitation operation vehicles face rigorous environmental challenges. A municipal sanitation department in Chongqing recently issued a public tender for a batch of Ford Transit V362 service vehicles, intended for daily inspections, emergency repairs, and equipment transportation. According to the tender announcement, a total of five units were procured, with an overall budget controlled between approximately RMB 3.15 million and RMB 4.5 million (unit price around RMB 80,000), emphasizing high reliability, low fuel consumption, and corrosion- and rust-resistance to adapt to Chongqing’s climatic characteristics — hot and rainy summers, and cold, humid winters. Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) — leveraging its extensive experience in government procurement and its full range of China VI-compliant products — successfully delivered this batch of Ford Transit V362 service vehicles. This article analyzes the technical rationale behind this procurement plan from key dimensions including engine comparison, fuel efficiency performance, adaptation to plateau vs. plain terrain, and anti-corrosion coating. II. Engine Comparison: Analysis of Differences Among 85 kW / 100 kW / 120 kW Options The Ford Transit V362 service vehicle is typically equipped with three engine options: 85 kW (~115 hp), 100 kW (~136 hp), and 120 kW (~163 hp). How are these engines selected in government procurement? We analyze this based on official announcement parameters of Chengli models such as CLW5070GSSD6. Engine Model | Power (kW) | Horsepower (Ps) | Emission Standard | Typical Application Ford 2.0T Diesel (85 kW) | 85 | 115 | China VI | Urban flat roads, light-load service Ford 2.0T Diesel (100 kW) | 100 | 136 | China VI | Urban mixed-road conditions, medium-load operations Ford 2.0T Diesel (120 kW) | 120 | 163 | China VI | Mountainous areas, high-altitude regions, heavy-load operations As shown in the table above, the 85 kW engine is suitable for urban flat roads and offers lower fuel consumption; the 100 kW engine represents a balanced choice, delivering both adequate power and fuel economy; while the 120 kW engine is specifically designed for complex operating conditions such as high altitudes and steep gradients. In Chongqing — a mountainous city — the Urban Management Bureau of a certain district ultimately selected the 100 kW variant, as it adequately meets routine inspection requirements while providing sufficient torque for hill climbing. III. Fuel Consumption Comparison: Fuel Economy Across Different Engines Based on official MIIT test data (e.g., for models such as CLW5070GSSD6), fuel consumption performance under standard operating conditions is as follows: 85 kW engine: Approx. 8.5–9.5 L/100 km — ideal for low-speed urban driving, though fuel consumption rises to over 10 L/100 km when climbing hills. 100 kW engine: Approx. 9.0–10.5 L/100 km — stable performance across mixed road conditions; Chongqing customers reported average fuel consumption of ~10.8 L/100 km during rainy-season operations. 120 kW engine: Approx. 10.5–12.5 L/100 km — higher fuel consumption, yet delivers superior efficiency under high-altitude or heavy-load conditions. For the Chongqing municipal sanitation department, the 100 kW engine’s fuel consumption profile best aligns with its requirement of ‘keeping unit cost within RMB X0,000’
