(3)As the fuel consumption values and CO2 emissions of heavy-duty vehicles resulting from the regulatory test procedures under Commission Regulation (EU) 2017/2400note is complemented by information recorded by the OBFCM device in accordance with Implementing Regulation (EU) 2025/2161 on the vehicles’ average real-world consumption when the vehicle is driven on the road, and as such information is essential for assessing that the regulatory procedures adequately reflect the average real-world CO2 emissions as well as the quantity of fuel and electric energy consumed, the accuracy of those OBFCM devices should be verified during on-road testing.
