A New Equation for Fuel Economy of Internal Combustion Engine Vehicles in Republic of Korea Based on 5-Cycle Test
摘要
The vehicle fuel economy rating system in South Korea has adopted the US 5-cycle fuel economy system since 2012 to provide consumers with comprehensive information. However, due to resource constraints, derived 5-cycle equations have been utilized to approximate 5-cycle test results using the 2-cycle test. This study examines the accuracy of derived 5-cycle fuel economy equations for 20 recent vehicle models in Korea and updates them based on the correlation between 5-cycle and 2-cycle fuel consumption. The updated equations are expected to refine fuel economy ratings for up to three models, ensuring the label's reliability.
