2. DETERMINATION OF THE NEDC CO2 VALUE FOR THE WLTP INTERPOLATION FAMILY
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.
2.1.1. 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 ( 2 ).
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 ( 3 )

2.1.2. Designation of correlation tool users
Member States shall inform the Commission of the respective contact points responsible for executing the correlation tool runs at the approval authority and, where applicable, at the technical services. Only one contact point per authority or service shall be designated. The information provided to the Commission shall include the following (the name of the organisation, the name of the person responsible, the postal address, the email address and the telephone number). This information shall be sent to the following functional mailbox ( 4 ):
EC-CO2-LDV-IMPLEMENTATION@ec.europa.eu
Electronic signing keys for the purpose of the execution of the correlation tool shall be provided only at the request of the contact point ( 5 ). The Commission shall publish guidance on the procedure to follow for such requests.
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:
(a) In the case two type approval tests are performed, the test results with the highest combined CO2 emissions shall be used;
(b) In the case three type approval tests are performed, the test results with the median combined 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.
2.3.1. Determination of the NEDC vehicle inertia
The NEDC reference mass of vehicles H and, where applicable, of vehicles L and R shall be determined as follows:
RMn,L = (MROL – 75 + 100) [kg]
RMn,H = (MROH – 75 + 100) [kg]
RMn,R = (MROR – 75 + 100) [kg]
Where,
Vehicle R is the representative vehicle of the Road Load Matrix Family as defined in point 5.1 of Sub-Annex 4 to Annex XXI to Commission Regulation (EU) 2017/1151 ( 6 );
MRO is the mass in running order as defined in Article 3(1)(d) of Regulation (EC) No 443/2009 for vehicles H, L and R respectively.
The reference mass to be used as input for the simulations and, where applicable, for a physical vehicle test 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, TMn,H and TMn,R.
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 point 6.6.3 of Appendix 3 to Annex I to Regulation (EU) 2017/1151, the lowest recommended tyre pressure for the vehicle test mass shall be used during the coast down for the road load determination, while this is not specified in the NEDC. The tyre pressure to be taken into account for the purpose of calculating the NEDC road load in accordance with point 2.3.8 shall 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 vehicle H and, where applicable, for vehicles L and R with the following formulae:
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 vehicles H, L and R:
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 the minimum tyre tread depth is 80 % 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 50 % of the nominal value. That 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 vehicles H, L and R:
Where,
RMn,H, RMn,L, and RMn,R are the reference masses of vehicles H, L and R 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 WLTP road loads being determined in accordance with paragraphs 1-4 and 6 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151

Unless otherwise specified the formulae shall apply both in the case of simulations and in the case of physical vehicle tests.
The type approval authority or, where applicable, the technical service shall verify if the wind-tunnel facility referred to in paragraph 3.2.3.2.2.3. in Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151 is qualified to accurately determine the Δ(Cd × Af) values. If the wind-tunnel facility is not qualified, the highest aerodynamic drag value shall apply for all vehicles in the family.
(a) The WLTP road load coefficients and test mass values referred to in the formulae set out in points 2.3.8.1.1. and 2.3.8.1.2. shall be those resulting from vehicle H and L as determined for the interpolation family in accordance with paragraph 5 of Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151.
(b) Notwithstanding point (a), where the cycle energy demand of the WLTP vehicle H and/or L does not result in the highest, or respectively, the lowest cycle energy demand for the NEDC vehicle H and/or L, the NEDC road load coefficients shall be determined in accordance with either of the following:
(i) on the basis of the individual vehicle in the interpolation family with the highest, or respectively, the lowest NEDC cycle energy demand;
(ii) on the basis of the combination of the highest, or respectively, the lowest of each of the road load relevant characteristics, i.e. aerodynamic drag, rolling resistance and mass, taken from any individual vehicle in the interpolation family.

4.2.1.4.1. Road load coefficients derived from NEDC vehicle H and L
The road load coefficients F0,n, F1,n and F2,n for vehicles H and L determined in accordance with point 2.3.8. are referred to as F0n,H, F1n,H and F2n,H and F0n,L, F1n,L and F2n,L respectively.
The road load coefficients f0n,ind, f1n,ind and f2n,ind for an individual vehicle shall be calculated in accordance with the following formula:
For new emission type approvals granted from 1 January 2019, or prior to that date, on the manufacturer's request, the road load coefficients shall be calculated in accordance with the following formula:
Or, if (TMn,H · RRn,H – TMn,L · RRn,L ) = 0, or, where applicable, (RMn,H · RRn,H – RMn,L · RRn,L ) = 0, Formula 2 shall apply:
f0n,ind = F0n,H – ΔF0n
f 1 n,ind = F 1 n,H
or, if Δ[Cd × Af]LH,n = 0, Formula 3 shall apply:
f 2 n,ind = F 2 n,H – ΔF 2 n
where:
ΔF 0,n = F 0n,H – F 0 n,L
ΔF 2,n = F 2n,H – F 2 n,L
4.2.1.4.2. Road load coefficients derived from WLTP road load coefficients of individual vehicles
From 1 January 2019 for new type approvals and from 1 January 2020 for all new vehicles entering into service, or prior to those dates at the request of the manufacturer, the NEDC road loads for an individual vehicle shall be derived from the WLTP road load coefficients of that vehicle in any of the following cases:
(a) if the CO2 emission value, the cycle energy demand, or any of the road load coefficients f0, f1 or f2 calculated in accordance with point 4.2.1.4.1., is to be extrapolated from NEDC vehicle H or L;
(b) if the road load coefficients for NEDC vehicle H and L are derived from different road load families;
(c) if the individual vehicle belongs to a road load family different to the road load family of NEDC vehicle H and/or L;
(d) if the individual vehicle belongs to a road load matrix family.
The NEDC road load coefficients shall, in the cases (a) to (d), be calculated using the formulae set out in point 2.3.8.1.1., where references to vehicle H shall be considered as references to the individual vehicle.
In the case (a), CO2 extrapolation may only be performed, if the difference between the NEDC vehicle H and L is equal to or higher than 5g CO2/km. The interpolation line may in that case be extrapolated by a maximum of 3g CO2/km above the CO2 emissions of vehicle H, or below the CO2 emissions of vehicle L. If the extrapolation exceeds 3g CO2/km, or the difference between NEDC vehicle H and L is less than 5g CO2/km, the manufacturer shall determine a new interpolation line for that interpolation family in accordance with point 2 and 3 of this Annex.
