The Second Monitoring Report on Chile's Energy Efficiency Law finds that while the light-duty vehicle industry exceeded the 2025 fuel economy standard of 18.8 km/lge (reaching 19.3 km/lge), this was primarily due to multipliers for plug-in vehicles; the actual sales-weighted economy was lower at 16.9 km/lge. Compliance among importers remained stagnant at 45%. Despite this, the market saw a 200% increase in available BEV models and a 32% decrease in available ICE models between 2023 and 2025. BEV and PHEV prices fell significantly, and the cost per kilometre for BEVs is now 70% lower than for ICE vehicles. These improvements contributed to a reduction of 9.1 million litres of gasoline demand and 21.4 thousand tonnes of CO2 emissions since 2024.

The 'Segundo Reporte de Monitoreo Eficiencia Energética de Vehículos Livianos en Chile' analyzes the impact of Law 21.305 on the light vehicle market during 2024 and 2025. It finds that while the average fuel efficiency of sold vehicles reached a historical record of 16.9 [km/lge] in 2025, this progress is heavily reliant on multipliers for plug-in vehicles, as only 45% of importers met their corporate efficiency standards.
