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(1), and in particular the first subparagraph of Article 13(7) thereof,
Whereas:
(1) Based on the experience gained from the implementation of Commission Regulation (EU) 2017/1151(2) and Commission Implementing Regulation (EU) 2017/1153(3), it has become evident that certain elements of the latter Regulation should be amended.
(2) It is necessary to complement the existing method for defining the end-points of the interpolation line used for calculating the NEDC CO2 emission value of an individual vehicle. Those end-points, which are represented by a test vehicle with the highest CO2 emission values, and test vehicle with the lowest values, should be defined so that the difference between the two test vehicles high and low is equal to or higher than 5 g CO2/km.
(3) In order to avoid that the CO2 emission values of individual vehicles are determined on the basis of interpolation lines that do not provide the minimum difference, it is appropriate that this amendment enters into force without delay.
(4) Where for the purpose of type approval under Regulation (EU) 2017/1151, road load matrix families are used, the calculation of the CO2 emission value of an individual vehicle belonging to such a family should be simplified by deriving the road load coefficients to be used for the calculation of the NEDC CO2 value from the road load coefficients of the individual vehicle as determined under Regulation (EU) 2017/1151.
(5) In order to ensure a robust correlation output, it is appropriate to add the number of cylinders as an input to be provided for the correlation tool.
(6) The opportunity should also be taken to correct some editorial errors in the text.
(7) The measures provided for in this Regulation are in accordance with the opinion of the Climate Change Committee,
HAS ADOPTED THIS REGULATION:
Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Regulation (EC) No 692/2008 (OJ L 175, 7.7.2017, p. 1).
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 (OJ L 175, 7.7.2017, p. 679).
