Size of the deviation in CO 2 emission values and determination of the vehicles concerned
Article 22
Where the granting approval authority has issued a conclusion as referred to in Article 21(4), point (b), the Commission shall determine the size of the deviation in the CO 2 emission values and all vehicles that are concerned, as follows: (a) for a VTP family, the size of the deviation in the CO 2 emission values is equal to the size of the deviations established by the granting approval authority and referred to in Article 21(4), point (b)(ii) of this Regulation. The vehicles concerned are all vehicles of the VTP family that have the same combination of engine and transmission. If the investigation under Article 8(2)(b) determines that the cause of the failure referred to in that provision is a component listed in Article 12(1), points (a) to (f), (h) and (j), of Regulation (EU) 2017/2400, the vehicles concerned are all vehicles with that component; (b) for an ISV air drag family, the Commission shall determine the size of the deviation in the CO 2 emission values for each vehicle subgroup of this ISV air drag family, based on re-running the reference model in the simulation tool with the declared value and with the corrected value for air drag. The corrected value for air drag is C d A declared multiplied by the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned are all vehicles of the ISV air drag family concerned, referred to in Article 21(4), point (b)(i), and all vehicles for which the air drag value has been transferred from an air drag family of that ISV air drag family; (c) for a CFD family, the Commission shall determine the size of the deviation in CO 2 emission values for each vehicle subgroup and for each air drag family of this CFD family, based on re-running the reference model in the simulation tool with the declared value and with the corrected value for air drag. The corrected value for air drag is equal to the air drag value for the parent (worst case) vehicle of each air drag family, or in case this value is determined by CFD simulation, the default value for this air drag family, minus the declared air drag value for each vehicle concerned. The vehicles concerned are all vehicles of that CFD family, and all vehicles for which the air drag value has been transferred from an air drag family of that CFD family; (d) for an ISV tyre family, the Commission shall determine the size of the deviation in the CO 2 emission values for each vehicle subgroup of this ISV tyre family, based on re-running the reference model in the simulation tool with the declared value and with the corrected value for the rolling resistance coefficient. The corrected value for the rolling resistance coefficient is RRC declared multiplied by the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned are all vehicles registered after 1 July 2025 using tyres from the ISV tyre family concerned, referred to in Article 21(4), point (b)(i); (e) for a mass test, the Commission shall determine the size of the deviation in the CO 2 emission values, based on re-running the fleet-average model in the simulation tool with the declared value and the corrected value for mass, for each vehicle sub-group of this manufacturer. The corrected value for mass is mass declared multiplied by the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned are all vehicles of the manufacturer; (f) in case an artificial strategy is present according to the conclusion referred to in Article 21(4), point (b), the size of the deviation in the CO 2 emission values is equal to the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned shall be determined based on the conclusion referred to in Article 21(4), point (b).
