Analysis of Fuel Cost Efficiency Through the Implementation of Speed Limiters in Distribution Fleets

Abstract

Introduction/Main Objectives: Fuel consumption efficiency is essential for controlling distribution fleet operating costs. This study evaluates the impact of speed limiter implementation on fuel efficiency. Background to the Problem: Although speed limiters are widely used for speed control, empirical evidence of their effectiveness under actual operating conditions remains limited. Novelty: This study combines quantitative fuel consumption analysis with qualitative findings from actual operational routes, providing a comprehensive assessment. Research Method: A mixed-method approach was employed. Quantitative data were obtained from four Mitsubishi L300 units, four Colt Diesel (CDE) units, and one Grandmax Box unit. Qualitative data were collected through interviews with management and logistics teams. Results/Findings: Speed limiter implementation improved fuel efficiency, with the consumption ratio increasing from 9–10 km/liter to 12–15 km/liter. Qualitative findings indicate that speed restrictions encourage more stable and efficient driving patterns. Conclusion: Speed limiters effectively improve fuel efficiency, reduce fuel costs, and support operational efficiency in distribution fleets.
