over the applicable cycle resulting from step 9 in Table A7/1 of Annex B7 between test vehicles L and H shall be 20 per cent plus 5 g/km of the CO2 emissions from vehicle H, but at least 15 g/km and not exceeding 30 g/km. See Figure A6/2.

              Interpolation range for pure ICE vehicles
              This restriction does not apply in relation to the application of a road load matrix family or when the calculation of the road load of vehicles L and H is based on the default road load.
              2.3.2.2.1. The allowed interpolation range defined in paragraph 2.3.2.2. of this annex may be increased by 10 g/km CO2 (see Figure A6/3) if a vehicle M is tested within that family and the conditions according to paragraph 2.3.2.4. of this annex are fulfilled. This increase is allowed only once within an interpolation family.

              2.3.2.3. At the request of the manufacturer and with approval of the responsible authority, the application of the interpolation method on individual vehicle values within a family may be extended if the maximum extrapolation of an individual vehicle (Step 10 in Table A7/1 of Annex B7) is not more than 3 g/km above the CO2 emission of vehicle H (Step 9 in Table A7/1 of Annex B7) and/or is not more than 3 g/km below the CO2 emission of vehicle L (Step 9 in Table A7/1 of Annex B7). This extrapolation is valid only within the absolute boundaries of the interpolation range specified in paragraph 2.3.2.2.
              For the application of a road load matrix family, or when the calculation of the road load of vehicles L and H is based on the default road load, extrapolation is not permitted.
              2.3.2.4. Vehicle M
              Vehicle M is a vehicle within the interpolation family between the vehicles L and H with a cycle energy demand which is preferably closest to the average of vehicles L and H.
              The limits of the selection of vehicle M (see Figure A6/4) are such that neither the difference in CO2 emission values between vehicles H and M nor the difference in CO2 emission values between vehicles M and L is greater than the allowed CO2 range in accordance with paragraph 2.3.2.2. of this annex. The defined road load coefficients and the defined test mass shall be recorded.

              The linearity of the corrected measured and averaged CO2 emission for vehicle M, MCO2,c,6,M according to step 6 of Table A7/1 of Annex B7, shall be verified against the linearly interpolated CO2 emission between vehicles L and H over the applicable cycle
