Having regard to Regulation (EU) 2019/631 of the European Parliament and of the Council of 17 April 2019 setting CO2 emission performance standards for new passenger cars and for new light commercial vehicles, and repealing Regulations (EC) No 443/2009 and (EU) No 510/2011(1), and in particular Article 11(4) thereof,
On 6 December 2018, the manufacturers Toyota Motor Europe NV/SA, Opel Automobile GmbH – PSA, FCA Italy S.p.A., Automobiles Citroën, Automobiles Peugeot, PSA Automobiles SA, Audi AG, Ford Werke GmbH, Jaguar Land Rover Ltd, Hyundai Motor Europe Technical Center GmbH, Bayerische Motoren Werke AG, Renault, Honda Motor Europe Ltd, Volkswagen AG and the supplier Robert Bosch GmbH submitted a joint application (‘the application’) for the approval as an innovative technology of the engine-on and engine-off coasting functions for use in internal combustion engine powered passenger and in not off-vehicle charging hybrid electric (NOVC-HEV) passenger cars.
The application has been assessed in accordance with Article 11 of Regulation (EU) 2019/631, Commission Implementing Regulation (EU) No 725/2011(2) and the Technical Guidelines for the preparation of applications for the approval of innovative technologies pursuant to Regulation (EC) No 443/2009 and Regulation (EU) No 510/2011 (July 2018 Revision V2)(3).
The application refers to CO2 emission savings that may not be demonstrated by measurements performed in accordance with the New European Driving Cycle (NEDC) as set out in Commission Regulation (EC) No 692/2008(4).
The coasting function decouples the combustion engine from the drivetrain and prevents deceleration caused by engine braking. It allows the rolling distance of the vehicle to increase in situations where no propulsion or a slow reduction of the speed is needed. The coasting function should be automatically activated in the predominant driving mode, which is the mode automatically selected when the engine is turned on.
The application concerns two distinct coasting functions: engine-on coasting and engine-off coasting. With engine-on coasting, the combustion engine remains switched-on during the coasting events with a certain fuel consumption required to retain idle speed. With engine-off coasting, the combustion engine is switched-off during the coasting events.
In determining the potential CO2 savings of the technologies, it is necessary to consider the effect on fuel consumption of the restart of the engine after the coasting event in the case of engine-off coasting, and of the need to bring engine speed up to the desired synchronisation speed for both technologies.
New information concerning the potential of the engine-off coasting function to save CO2 emissions became available to the Commission during the course of 2019, i.e. well after the submission of the application. Additional data was requested from the applicants and this was made available in February 2020.
As regards the engine-off coasting function, it has not been possible, on the basis of the supporting data provided, to conclusively determine the level of CO2 savings that may be achieved.
In particular, it has not been sufficiently demonstrated that the CO2 savings achieved by switching off the engine are not offset by the CO2 emissions resulting from the energy required to restart the engine and to bring the engine speed up to the desired synchronisation speed.
The engine-on coasting function for use in passenger cars powered by an internal combustion engine has already been approved as an eco-innovation in relation to the NEDC emissions test by Commission Implementing Decisions (EU) 2015/1132(5), (EU) 2017/1402(6) and (EU) 2018/2079(7).
Based on the experience gained from those Decisions, together with the information provided with the present application, it has been satisfactorily and conclusively demonstrated that the engine-on coasting function for use in passenger cars powered by an internal combustion engine meets the criteria referred to in Article 11(2) of Regulation (EU) 2019/631 and the eligibility criteria specified in Article 9(1)(a) of Implementing Regulation (EU) No 725/2011.
For certain NOVC-HEVs for which uncorrected measured fuel consumption and CO2 emission values may be used in accordance with Annex 8 to Regulation No 101 of the Economic Commission for Europe of the United Nations(8), it has been demonstrated that the same conditions apply as for internal combustion engine powered passenger cars. As regards other NOVC-HEVs, those conditions cannot be considered applicable, as it has not been sufficiently substantiated in the application how the CO2 savings from the use of the engine-on coasting function in such NOVC-HEVs are to be determined.
The testing methodology proposed by the applicants for determining the CO2 savings from the use of the engine-on coasting function differs from the one approved in Implementing Decision (EU) 2018/2079 in the way the baseline vehicle is to be tested. As the methodology simplifies the testing process, whilst ensuring more conservative results, it is appropriate to approve it for the purpose of determining the CO2 savings of the technology in question.
Manufacturers should have the possibility to apply to a type-approval authority for the certification of CO2 savings from the use of the innovative technology where the conditions laid down in this Decision are met. Manufacturers should for that purpose ensure that the application for certification is accompanied by a verification report from an independent and certified body confirming that the innovative technology complies with the conditions laid down in this Decision and that the savings have been determined in accordance with the testing methodology referred to in this Decision.
It is the responsibility of the type-approval authority to verify thoroughly that the conditions for certifying the CO2 savings from the use of an innovative technology as specified in this Decision are met. Where the certification is issued, the responsible type-approval authority should ensure that all elements considered for the certification are recorded in a test report and kept together with the verification report and that this information is made available to the Commission on request.
For the purpose of determining the general eco-innovation code to be used in the relevant type-approval documents in accordance with Annexes I, III, VI and VIII to Commission Implementing Regulation (EU) 2020/683(9), it is necessary to attribute an individual code to the innovative technology.
From 2021, manufacturers’ compliance with their specific emissions targets under Regulation (EU) 2019/631 is to be established on the basis of the CO2 emissions determined in accordance with the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) set out in Commission Regulation (EU) 2017/1151(10). CO2 savings from the innovative technology certified by reference to this Decision may therefore be taken into account for the calculation of a manufacturer’s average specific emissions of CO2 only for calendar year 2020.
In view of the change to WLTP, it is appropriate to repeal with effect from 1 January 2021 this Decision together with the following Implementing Decisions that refer to the conditions applicable under the NEDC, i.e. Commission Implementing Decisions 2013/128/EU(11), 2013/341/EU(12), 2013/451/EU(13), 2013/529/EU(14), 2014/128/EU(15), 2014/465/EU(16), 2014/806/EU(17), (EU) 2015/158(18), (EU) 2015/206(19), (EU) 2015/279(20), (EU) 2015/295(21), (EU) 2015/1132, (EU) 2015/2280(22), (EU) 2016/160(23), (EU) 2016/265(24), (EU) 2016/588(25), (EU) 2016/362(26), (EU) 2016/587(27), (EU) 2016/1721(28), (EU) 2016/1926(29), (EU) 2017/785(30), (EU) 2017/1402, (EU) 2018/1876(31), (EU) 2018/2079, (EU) 2019/313(32), (EU) 2019/314(33), (EU) 2020/728(34), (EU) 2020/1102(35), (EU) 2020/1222(36).
Taking into account that the time of applicability of this Decision is limited, it is appropriate to ensure that it enters into force as soon as possible and not later than seven days following its publication in the Official Journal of the European Union,
