COMMISSION IMPLEMENTING REGULATION (EU) 2017/1152

of 2 June 2017

setting out a methodology for determining the correlation parameters necessary for reflecting the change in the regulatory test procedure with regard to light commercial vehicles and amending Implementing Regulation (EU) No 293/2012

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

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

Having regard to Regulation (EU) No 510/2011 of the European Parliament and of the Council of 11 May 2011 setting emission performance standards for new light commercial vehicles as part of the Union’s integrated approach to reduce CO2 emissions from light-duty vehicles (1), and in particular the first subparagraph of Article 8(9) and the third subparagraph of Article 13(6) thereof,

Whereas:

| (1) | A new regulatory test procedure for measuring CO2 emissions and fuel consumption from light duty vehicles, the Worldwide Harmonised Light Vehicles Test Procedure (WLTP), set out in Commission Regulation (EU) 2017/1151 (2), will replace the New European Test Cycle (NEDC), which is currently used pursuant to Commission Regulation (EC) No 692/2008 (3), 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. |

(1)

A new regulatory test procedure for measuring CO2 emissions and fuel consumption from light duty vehicles, the Worldwide Harmonised Light Vehicles Test Procedure (WLTP), set out in Commission Regulation (EU) 2017/1151 (2), will replace the New European Test Cycle (NEDC), which is currently used pursuant to Commission Regulation (EC) No 692/2008 (3), 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 (EU) No 510/2011. |

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 (EU) No 510/2011.

| (3) | For light commercial vehicles, the WLTP is to be gradually applied in two separate steps, starting with new N1 class I vehicle types from 1 September 2017 and all new N1 class I vehicles from 1 September 2018. The WLTP will be implemented 1 year later for category N1 class II and III, i.e. for new vehicle types from 1 September 2018 and for all new vehicles from 1 September 2019. End-of-series vehicles as defined in point (22) of Article 3 of Directive 2007/46/EC of the European Parliament and of the Council (4) belonging to the latter category N1 class II and III may however remain on the market until 28 February 2021 at the latest in accordance with Article 27 of Directive 2007/46/EC. |

| (4) | While it is appropriate to continue verifying compliance with specific emission targets using NEDC based CO2 emission values during the separate steps of gradual application of the WLTP, it is also desirable to ensure that the change to WLTP based targets takes place at the same time for all light duty vehicles. As a consequence, it is necessary to take into account the end-of-series vehicles that will remain on the market until 2021 and attribute a default WLTP CO2 emissions value to those vehicles. That default value should be defined so that it does not affect negatively the manufacturer’s ability to comply with its specific emission target in 2021. |

That default value should be defined so that it does not affect negatively the manufacturer’s ability to comply with its specific emission target in 2021.

| (5) | Consideration should also be given to the specific situation of manufacturers of incomplete vehicles as defined in Article 3(19) of Directive 2007/46/EC which are type approved in multiple stages. For the purposes of the correlation, it is appropriate to attribute a single correlated NEDC CO2 emissions value to incomplete vehicles belonging to the same road load matrix family as defined in point 5.2 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151. |

| (6) | Moreover, manufacturers should be allowed, in the case of N1 vehicles with a technically permissible maximum laden mass of 3 000 kg or more to have the choice to either derive NEDC road load coefficients from the WLTP tests or to use the tabulated values set out in Table 3 of Annex 4(a) to Regulation UN/ECE No 83 (5). |

| (7) | It is 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. |

The input data for the correlation tool should not require additional tests but be derived from the WLTP type approval tests.

| (8) | The stringency of the CO2 reduction requirements following the change to WLTP must, in accordance with the fourth subparagraph of Article 13(6) to Regulation (EU) No 510/2011, remain comparable for manufacturers and vehicles of different utility to that defined in Regulation (EU) No 510/2011 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. |

The correlation procedure should therefore take into account those NEDC test conditions which are explicitly required for granting a type approval.

| (9) | 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. |

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.

| (10) | In order to ensure comparable stringency, it is necessary to make certain adjustments to the calculation of the eco-innovation savings referred to in Article 12 of Regulation (EU) No 510/2011. However, the framework conditions for that modality are considered not to be directly dependent on the applicable test procedure, and, should, as a consequence, be maintained without adjustments, including the cap set for the eco-innovation savings. |

| (11) | 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. |

| (12) | The monitoring of CO2 emission values is regulated in Commission Implementing Regulation (EU) No 293/2012 (6). The provisions of that Implementing Regulation need to be adjusted to the new test procedure. It is also appropriate to align the monitoring provisions for light commercial vehicles with the monitoring provisions for passenger cars set out in Commission Regulation (EU) No 1014/2010 (7). With the WLTP, a specific CO2 emission value will be calculated and recorded in the certificate of conformity of each individual vehicle and those values should be monitored in addition to already existing data parameters. Therefore, Implementing Regulation (EU) No 293/2012 should be amended accordingly. |

2.3.1.   Determination of the NEDC vehicle inertia

2.3.1.1.   NEDC reference mass of vehicle H, and where applicable of vehicle L, and of the representative vehicle of a road load matrix family in the case of completed vehicles

The NEDC reference mass of vehicles H and L of the WLTP interpolation family and vehicle R of the WLTP road load matrix family shall be determined as follows:

Formula

Formula

Formula

Where,

MRO is the mass in running order as defined in Article 3(g) of Regulation (EU) No 510/2011 for vehicle 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 shall be referred to as TMn,L, TMn,H and TMn,R.

2.3.1.2.   NEDC reference mass of the representative vehicle of a road load matrix family in the case of incomplete vehicles to be submitted to multi-stage type approval

In the case of incomplete N1 vehicles, the NEDC reference mass (RMn,MSV) of the representative vehicle in the road load matrix family shall be determined as follows:

Formula

Where,

MRO is as defined in point 2.3.1.1, and

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 Section 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 % 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. 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 vehicle H, and where applicable, for vehicles L and R in accordance with the following formulae:

For vehicle H:

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:

For vehicle H:

For vehicle L:

For vehicle 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:

For vehicle H:

For vehicle L:

For vehicle R:

Where,

RMn,H, RMn,L or RMn,R are the reference masses of vehicle H, L and R determined in accordance with point 2.3.1.1.

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 shall be considered, while for the purpose of the NEDC tests only two rotating wheels shall 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 shall 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 shall be transferred to forces and vice versa by neglecting the effect of rotational mass (only the 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 points 4 and 6 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151 for complete N1 vehicles

The NEDC road load coefficients for complete N1 vehicles shall be calculated in accordance with the formulae specified in point 2.3.8.1.1 of this Annex (for vehicle H) and in point 2.3.8.1.2 (for vehicle L).
