Commission Implementing Regulation (EU) 2017/1153 of 2 June 2017 setting out a methodology for determining the correlation parameters necessary for reflecting the change in the regulatory test procedure and amending Regulation (EU) No 1014/2010 (Text with EEA relevance)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
This is the original version as it was originally adopted in the EU.
This legislation may since have been updated - see the latest available (revised) version
The manufacturer shall calculate the (phase-specific and combined) NEDC CO2 values and the fuel consumption values to be attributed to individual passenger cars in accordance with points 4.1 and 4.2 and record those values in the certificates of conformity.
The provisions on rounding set out in point 1.3 of Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151 shall apply.
Where the CO2 emissions of the WLTP interpolation family are determined by reference to vehicle H only in accordance with point 1.2.3.1 of Sub-Annex 6 to Annex XXI to Regulation (EU) 2017/1151, the NEDC CO2 value to be recorded in the certificates of conformity of the vehicles belonging to that family shall be the NEDC CO2 emissions determined in accordance with point 3.2 of this Annex and recorded in the type-approval certificate of the vehicle H in question.
The NEDC reference mass of the individual vehicle (RMn,ind) shall be determined as follows:
Where: MRO ind is the mass in running order as defined in Article 3(d) of Regulation (EC) No 443/2009 of the individual vehicle.
The mass to be used for the calculation of the NEDC CO2 values of the individual vehicle 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 determined in accordance with this point and referred to as. TMn,ind.
The tyre rolling resistance values determined in accordance with point 3.2.3.2.2.2 of sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151 shall be used for the purpose of the interpolation of the NEDC CO2 value of the individual vehicle.
The aerodynamic drag of the individual vehicle shall be calculated by considering the difference in aerodynamic drag between an individual vehicle and vehicle L, due to a difference in body shape (m2):
Where:
is the aerodynamic drag coefficient;
is the frontal area of the vehicle, m2.
The type-approval authority or, where applicable, the technical service shall verify if the wind tunnel facility referred to in 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) for body shapes that differ between vehicle L and H. If the wind tunnel facility is not qualified, the for vehicle H shall apply for the individual vehicle.
If vehicles L and H have the same body shape, the value of for the interpolation method shall be set to zero.
The road load coefficients F0,n, F1,n and F2,n for test 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:
or, if = 0, Formula 3 shall apply:
where:
The cycle energy demand of the applicable NEDC Ek,n and the energy demand for all applicable cycle phases Ek,p,n applicable for individual vehicles in the WLTP interpolation family shall be calculated according to the procedure in paragraph 5 of Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151, for the following sets k of road load coefficients and masses:
In case the chassis dynamometer coefficients specified in Table 3 of Annex 4a of UN/ECE Regulation No 83 are applied, the following formulae shall be used:
For each cycle phase p of the NEDC applicable for individual vehicles in the WLTP interpolation family, the contribution to the total mass of CO2 for an individual vehicle shall be calculated as follows:
The mass of CO2 emissions, g/km, attributed to an individual vehicle of the WLTP interpolation family shall be calculated as follows:
The terms E1,p,n, E2,p,n, E3,p,n, and E1,n, E2,n, E3,n respectively are defined in paragraph 4.2.1.5.
For each cycle phase p of the NEDC applicable for individual vehicles in the WLTP interpolation family, the fuel consumption, l/100km, shall be calculated as follows:
The fuel consumption, l/100km, of the complete cycle for an individual vehicle of the WLTP interpolation family shall be calculated as follows:
The terms E1,p,n, E2,p,n, E3,p,n, and E1,n, E2,n, E3,n respectively are defined in paragraph 4.2.1.5.
