BAKGRUNN (fra kommisjonsforordningen)

(1) Commission Regulation (EU) 2017/2400 introduced a common method to compare the performance of heavy-duty vehicles placed on the Union market as regards their CO2 emissions and fuel consumption. It lays down provisions for the certification of components with an impact on CO2 emissions and fuel consumption of heavy-duty vehicles, introduces a simulation tool for the purpose of determining and declaring CO2 emissions and fuel consumption of those vehicles, and lays down, inter alia, requirements for Member States’ authorities and manufacturers to verify the conformity of the certification of the components and the conformity of the simulation tool operation. 

(2) Commission Regulation (EU) 2022/1379 expanded the scope of Regulation (EU) 2017/2400 to medium lorries and heavy buses and added new technologies such as hybrid and pure electric vehicles, dual-fuel vehicles and waste heat recovery. 

(3) As other new technologies are being developed and may enter the market in the future, requirements for such new technologies should be laid down. Such new technologies should include vehicles running on hydrogen, efficient wheel ends, vehicles propelled by several drivetrains operating independently or vehicles capable of recharging while in motion. 

(4) As it may be unclear at the time of certification of the CO2 emissions and fuel consumption values whether a vehicle will be a vocational vehicle or not, all simulations for vehicles in the concerned groups should be simulated on all mission profiles. The correct allocation of the certified CO2 emissions and fuel consumption values should thus be made depending on the status of the registration of the vehicle. 

(5) As equipping vehicles with efficient wheel ends makes a positive impact on CO2 emissions, a new procedure is introduced to allow for the certification of efficient wheel ends in order to ensure that their high efficiency is reflected in the determination CO2 and fuel consumption values. 

(6) The procedure for determining the air drag performances of vehicles should be reinforced in order to improve its repeatability and reproducibility and, in order to reduce the testing burden and to ensure that features improving aerodynamic performances can be effectively certified it should be complemented with a new process relying on computational fluid dynamics simulation. 

(7) As the on-road verification testing procedure proved to be an important tool for the verification of calculations of CO2 emissions and fuel consumption of medium and heavy lorries, it should also apply to heavy buses, with certain adjustments to reflect the complexity of the frequent multi-step production of such vehicles. 

(8) As new technologies will be covered by this Regulation, notably for medium lorries, conflicting obligations between Regulation (EU) 2017/2400 and the Worldwide harmonised Light-duty vehicles Test Procedures for the purpose of determining CO2 emissions and fuel consumption values as prescribed in Commission Regulation (EU) 582/2011 should be avoided. Commission Regulation (EU) 582/2011 should be amended accordingly to ensure that no medium lorries are tested under two different regimes for the purpose of determining CO2 emissions and fuel consumption values. 

(9) In order to provide Member States, national authorities and economic operators with sufficient time to prepare for the application of the rules introduced by this Regulation, its date of application should be deferred. 

(10) In order to allow for an early application of the Regulation, in particular for technologies newly covered by this amendment, it should be possible to obtain a licence to operate the simulation tool and to receive a certification for components in accordance with Regulation (EU) 2017/2400 as amended by this Regulation as of the entry into force. 

(11) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles,
