to the procedure in paragraph 5. of Annex B7 for the sets k of road load coefficients and masses according to paragraph 3.2.3.2.3. of Annex B7.
              4.5.3. Calculation of the interpolation coefficient for individual vehicles
              The interpolation coefficient  per period shall be calculated for each considered period p using the following equation:

              where:

                      is the interpolation coefficient for the considered individual vehicle for period p;

                      is the energy demand for the considered period for vehicle L according to paragraph 5. of Annex B7, Ws;

                      is the energy demand for the considered period for vehicle H according to paragraph 5. of Annex B7, Ws;

                      is the energy demand for the considered period for the individual vehicle according to paragraph 5. of Annex B7, Ws;

                      is the index of the individual period within the applicable test cycle.

              In the case that the considered period p is the applicable WLTP test cycle,  is named .

              4.5.4. This paragraph is applicable only for Level 1A:

              Interpolation of the CO2 emission for individual vehicles

              4.5.4.1. Individual charge-sustaining CO2 emission for OVC-HEVs and NOVC-HEVs

              The charge-sustaining CO2 emission for an individual vehicle shall be calculated using the following equation:

              where:

                      is the charge-sustaining CO2 emission for an individual vehicle of the considered period p according to Table A8/5, step No. 9, g/km;

                      is the charge-sustaining CO2 emission for vehicle L of the considered period p according to Table A8/5, step No. 8, g/km;

                      is the charge-sustaining CO2 emission for vehicle H of the considered period p according to Table A8/5, step No. 8, g/km;

                      is the interpolation coefficient for the considered individual vehicle for period p;

                      is the index of the individual period within the applicable WLTP test cycle.

              The considered periods shall be the low phase, medium phase, high phase, extra high phase and the applicable WLTP test cycle.

              4.5.4.2. Individual utility factor-weighted charge-depleting CO2 emission for OVC-HEVs

              The utility factor-weighted charge-depleting CO2 emission for an individual vehicle shall be calculated using the following equation:

              where:

                      is the utility factor-weighted charge-depleting CO2 emission for an individual vehicle, g/km;

                      is the utility factor-weighted charge-depleting CO2 emission for vehicle L, g/km;

                      is the utility factor-weighted charge-depleting CO2 emission for vehicle H, g/km;

                      is the interpolation coefficient for the considered individual vehicle for the applicable WLTP test cycle.

              4.5.4.3. Individual utility factor-weighted CO2 emission for OVC-HEVs

              The utility factor-weighted CO2 emission for an individual vehicle shall be calculated using the following equation:

              where:

                          is the utility factor-weighted CO2 emission for an individual vehicle, g/km;

                          is the utility factor-weighted CO2 emission for vehicle L, g/km;

                          is the utility factor-weighted CO2 emission for vehicle H, g/km;

                          is the interpolation coefficient for the considered individual vehicle for the applicable WLTP test
