THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 443/2009 of the European Parliament and of the Council of 23 April 2009 setting emission performance standards for new passenger cars as part of the Community’s integrated approach to reduce CO2 emissions from light-duty vehicles, and in particular the first subparagraph of Article 8(9) and the first subparagraph of Article 13(7) thereof,

Whereas:

(1) A new regulatory test procedure for measuring CO2 emissions and fuel consumption from light-duty vehicles, the World Harmonised Light Vehicles Test Procedure (WLTP), set out in Commission Regulation (EU) 2017/1151, will replace the New European Test Cycle (NEDC), which is currently used pursuant to Commission Regulation (EC) No 692/2008, with effect starting from 1 September 2017. The WLTP is expected to provide CO2 emission and fuel consumption values that are more representative of real driving conditions.

(2) In order to take into account the difference in the level of CO2 emissions measured under the existing NEDC and the new WLTP procedures, a methodology for correlating those values should be provided to allow the determination of the manufacturers’ compliance with their specific CO2 emission targets pursuant to Regulation (EC) No 443/2009.

(3) The WLTP is to be phased in, starting with new vehicle types from 1 September 2017 and all vehicles from 1 September 2018. From 1 September 2019, when also end-of-series vehicles have been phased out, all new vehicles placed on the Union market will be tested in accordance with the WLTP. It is appropriate to continue to verify compliance with the specific emission targets using NEDC-based CO2 emission values during this period.

(4) It is however desirable to limit the testing burden for both manufacturers and type-approval authorities and the possibility to determine the reference NEDC CO2 emission values by way of simulations should therefore be provided. A specific vehicle simulation tool (the correlation tool) has been developed for that purpose. The input data for the correlation tool should not require additional tests but be derived from the WLTP type-approval tests.

(5) The stringency of the CO2 reduction requirements following the change to WLTP must, in accordance with the second subparagraph of Article 13(7) to Regulation (EC) No 443/2009, remain comparable for manufacturers and vehicles of different utility to that defined in Regulation (EC) No 443/2009 by reference to the CO2 emission levels determined in accordance with the NEDC procedure. The correlation procedure should therefore take into account those NEDC test conditions which are explicitly required for granting a type-approval.

(6) There may be advanced vehicle technologies or specific technology configurations for which the correlation tool might not be able to deliver NEDC CO2 values with sufficient accuracy. In those cases, the manufacturer should have the possibility to perform a physical vehicle test instead. In order to ensure a level playing field, the same NEDC test conditions that have been defined for the correlation tool should apply for those tests.

(7) Regulation (EC) No 443/2009 provides a number of modalities which may be applied to facilitate achieving the specific emission targets. In order to ensure comparable stringency, it is necessary to make certain adjustments to the calculation of the super-credits specified in Article 5a of Regulation (EC) No 443/2009 and to the eco-innovation savings referred to in Article 12 of that Regulation. However, the framework conditions for those modalities are considered not to be directly dependent on the applicable test procedure, and, should, as a consequence, be maintained without adjustments, including the caps set for both super-credits and eco-innovation savings.

(8) It is important to ensure that procedural tolerances and correlation tool outputs are applied as intended and not as a means to artificially lower the CO2 emission values used for target compliance purposes. Therefore, a limited number of random physical tests should be performed with a view to verifying that the input data and the NEDC reference values based on the correlation tool output are correctly determined. If it is found, as a result of a random test, that a manufacturer has declared an NEDC CO2 value for the purpose of the type-approval that is lower than the tolerance permitted in the measurement result or if incorrect input data has been provided, it should be possible for the Commission to determine and apply a correction factor to increase the average specific emissions of a manufacturer. This should also act as a disincentive for any abuse or overexploitations of measurement tolerances.

(9) The monitoring of CO2 emission values is set out in Commission Regulation (EU) No 1014/2010 and these provisions also needs to be adjusted to the new test procedure. With the WLTP, a specific CO2 emission value will be calculated and recorded in the certificate of conformity of each individual vehicle. In order to effectively monitor and verify those values, it is necessary to use vehicle identification numbers as a basis for the monitoring.

(10) In view of the required extensive adaptations of vehicle registration and CO2 monitoring systems, it is appropriate to provide Member States with the possibility to gradually introduce the new monitoring parameters in 2017 and require the complete new dataset from 2018 only. The 2017 data to be reported should include as a minimum the data required for target compliance purposes and for preventing abuse of the correlation procedure.

(11) The measures provided for in this Regulation are in accordance with the opinion of the Climate Change Committee,

ANNEX

ANNEX I

1. INTRODUCTION This Annex sets out the methodology for determining the NEDC CO2 value of individual M1 vehicles.

2. DETERMINATION OF THE NEDC CO2 VALUE FOR THE WLTP INTERPOLATION FAMILY

2.

2.1. Correlation tool The type-approval authority shall ensure that the NEDC CO2 values to be used as reference for the purpose of Section 3 are determined by way of simulations in accordance with the provisions set out in this Annex. The Commission shall provide a simulation tool for that purpose (hereinafter the correlation tool) in the form of downloadable, executable, software. The Commission shall also provide guidance on the capacity of the correlation tool to simulate vehicles with advanced technologies, and, where necessary, recommend the use of physical measurements instead of simulations.

2.1.

2.1.1. Access to the correlation tool The correlation tool shall be installed on a computer of the type-approval authority or, where applicable, the technical service, following the instructions provided in the following website: (http://ec.europa.eu/clima/policies/transport/vehicles/cars/documentation_en.htm) The type-approval authority shall ensure that the correlation tool is operated in accordance with the requirements of this Regulation and the user instructions set out in the user manual. Support to the approval authorities and technical services using the correlation tool for the purpose of this Regulation shall be provided by the Commission on request. Requests for support shall be addressed to the following functional mailbox: co2mpas@jrc.ec.europa.eu The correlation tool shall be accessible to other users, however, support shall only be provided to those users within the limits of available resources.

2.1.2. Electronic signature and sealing of the correlation tool output An electronic signing-key for the purpose of electronically signing and sealing the original correlation tool output file referred to in point 3.1 shall be made available to the approval authorities and, where applicable, technical services following a request to the Commission. The request shall include the relevant name and contact details (mail address, email address, telephone number) of the person responsible for the execution of the correlation tool output and be sent to the following functional mailbox: EC-CO2-LDV-IMPLEMENTATION@ec.europa.eu

2.1.3. Annual update of the correlation tool The performance of the correlation tool shall be continuously reviewed, taking into account information provided, in particular, by the contact persons referred to in point 2.1.2. Where appropriate, the Commission shall prepare a new version of the tool to be released annually on 1 September. The new version shall not affect the validity of results provided by previous versions. The new version may be applied for the purpose of the procedure set out in Section 3 of this Annex from the date of its release. With the agreement of the type-approval authority or the technical service, the previous version of the correlation tool may, however, continue to be used during a maximum period of two months following the release of the new version. The version used as well as the operating system of the computer on which the correlation tool has been run by the type-approval authority or technical service shall be indicated in the electronically signed correlation tool output report. Where the applicability of the new version requires the adjustment of any provisions set out in this Regulation, the release of the new version shall not take place until the Regulation has been amended accordingly.

2.1.4. Ad-hoc adjustments of the correlation tool Notwithstanding point 2.1.3, in case of serious malfunctioning of the correlation tool for the purpose of the procedure set out in Section 3, a new version of the tool shall be prepared and released as soon as possible following the detection of the malfunction. The new version shall apply from the date of its release and shall not affect the validity of results provided by previous versions. Where the applicability of the new version requires the adjustment of any provisions set out in this Regulation, the release of the new version shall not take place until the Regulation has been amended accordingly.

2.2. Identification of the WLTP test results to be used for the purpose of defining the input data for the simulation model The input data for the correlation tool simulations shall be taken from the relevant WLTP test results for vehicle H and, where applicable, vehicle L as defined in accordance with point 4.2.1 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151. Where more than one WLTP type-approval test of vehicle H or L is performed in accordance with Table A6/2 of Annex XXI to that Regulation, the following test results shall be used for the purpose of determining the input data:

2.2.

(a) in the case where two type-approval tests are performed, the test results with the highest CO2 emissions shall be used;

(b) in the case where three type-approval tests are performed, the test results with the median CO2 emissions shall be used.

2.3. Determination of the input data and conditions for the operation of the correlation tool The test conditions referred to in Annex XII to Regulation (EC) No 692/2008 shall be taken into account in the correlation tool simulations, including the precisions provided for in points 2.3.1 to 2.3.7 of this Annex. The physical vehicle measurements referred to in point 3 shall be performed in accordance with the conditions referred to in that Regulation, with the precisions given in this Annex, and, where applicable, the input data defined in point 2.4.

2.3.

2.3.1. Determination of the NEDC vehicle inertia The NEDC reference mass of vehicles H and L shall be determined as follows: RMn,L MROL 75 100 [kg]RMn,H MROH 75 100 [kg] Where: MRO is the mass in running order as defined in Article 3(d) of Regulation (EC) No 443/2009 for vehicle H and L respectively. The reference mass to be used as input for the simulations shall be the inertia value set out in Table 3 of Annex 4a to UN/ECE Regulation No 83 which is equivalent to the reference mass, RM, determined in accordance with this point and referred to as TMn,L and TMn,H.

2.3.2. Determination of the pre-conditioning effect In preparing the chassis-dynamometer for the execution of a type-approval test, the vehicle is pre-conditioned in order to reach similar conditions to those used in the coast-down test. The pre-conditioning procedure used in the WLTP test differs from that used for the purpose of NEDC so that, with equal road loads, the vehicle is considered subject to higher forces under the WLTP. That difference shall be set at 6 Newton and that value shall be used for the calculation of the NEDC road loads in accordance with point 2.3.8.

2.3.3. Ambient conditions referred to in point 3.1.1 of UN/ECE Regulation No 83 For the purpose of the correlation tool, the test cell temperature shall be set at 25 °C. Also in the case of a physical vehicle measurement pursuant to point 3, the test cell temperature shall be set at 25 °C. However, on request by the manufacturer, the test cell temperature may be set at a value between 20 to 25 °C for the physical measurement.

2.3.4. Determination of the initial battery state of charge The initial battery state of charge shall be set to at least 99 per cent for the purpose of the correlation tool test. The same shall apply in the case of a physical vehicle test.

2.3.5. Determination of the difference in tyre pressure prescriptions According to the WLTP, the lowest tyre pressure for the vehicle test mass shall be used, while this is not specified in the NEDC. For the purpose of determining the tyre pressure to be taken into account for the purpose of calculating the NEDC road load in accordance with point 2.3.8, the tyre pressure shall, taking into account the different tyre pressure per vehicle axle, be the average between the two axles of the average between the minimum and maximum tyre pressure permitted for the selected tyres on each axle for the NEDC reference mass of the vehicle. The calculation shall be carried out for both vehicles H and L in accordance with following formulae: For vehicle H Pavg,H Pmax,H Pmin,H2 For vehicle L Pavg,L Pmax,L Pmin,L2 Where: Pmax, is the average of the maximum tyre pressures of the selected tyres for the two axles; Pmin, is the average of the minimum tyre pressures of the selected tyres for the two axles. The corresponding effect in terms of resistance applied to the vehicle shall be calculated using the following formulae for the respective vehicle H and L: TPH Pavg,HPmin,H 0,4TPL Pavg,LPmin,L 0,4

2.3.6. Determination of the tyre tread depth (TTD) According to point 4.2.2.2 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151 a minimum tyre tread depth of 80 % is to be considered for the WLTP test, while pursuant to point 4.2 of Appendix 7 to Annex 4a to UN/ECE Regulation No 83, the minimum allowed tyre tread depth for the purpose of the NEDC test is to be considered as equal to 50 % of the nominal value. This results in an average difference of 2 mm in tread depth between the two procedures. The corresponding effect in terms of the resistance applied to the vehicle shall be determined for the purpose of the NEDC road load calculation in point 2.3.8 in accordance with the following formulae for the respective vehicle H and L: TTDH 2 ·0,1 · RMn,H · 9,811000TTDL 2 ·0,1 · RMn,L · 9,811000 Where: RMn,H and RMn,L are the reference masses of vehicle H and L determined in accordance with point 2.3.1.

2.3.7. Determination of the inertia of rotating parts For the purpose of the correlation tool: During the simulation of the WLTP test four rotating wheels are to be considered, while for the purpose of the NEDC tests only two rotating wheels are to be considered. The effect this has on the forces applied to the vehicle shall be taken into account in accordance with the formulae set out in point 2.3.8.1.1(a)(3). The acceleration and deceleration forces in the correlation tool shall be calculated for the NEDC simulation by considering the inertia of only two rotating wheels. For the purpose of a physical test: During the WLTP coastdown setting, coastdown times are to be transferred to forces and vice versa by taking into account the applicable test mass plus the effect of rotational mass (3 % of the sum of the MRO and 25 kg). For the NEDC coastdown setting, coastdown times are to be transferred to forces and vice versa by neglecting the effect of rotational mass (only NEDC vehicle inertia calculated in point 2.3.1 is used).

2.3.8. Determination of the NEDC road loads

2.3.8.1. In the case of road loads being determined in accordance with points 1-4 and 6 of Sub-Annex 4 of Annex XXI to Regulation (EU) 2017/1151
