applicable cycle, the fuel efficiency, km/l, for an individual vehicle shall be calculated using the following equation:

              The fuel efficiency in km/l, of the complete cycle for an individual vehicle shall be calculated using the following equation:
              The terms E1,p, E2,p and E3,p, and E1, E2 and E3 respectively shall be calculated as specified in paragraph 3.2.3.2.3. of this annex.
              3.2.3.2.6. For Level 1A
              The individual CO2 value determined in paragraph 3.2.3.2.4. of this annex may be increased by the original equipment manufacturer (OEM). In such cases:
                  (a)  The CO2 phase values shall be increased by the ratio of the increased CO2 value divided by the calculated CO2 value;
                  (b)  The fuel consumption values shall be increased by the ratio of the increased CO2 value divided by the calculated CO2 value.
              This shall not compensate for technical elements that would effectively require a vehicle to be excluded from the interpolation family.
              For Level 1B
              The individual fuel efficiency value determined in paragraph 3.2.3.2.5. of this annex may be decreased by the original equipment manufacturer (OEM). In such cases:
                  (a)  The fuel efficiency phase values shall be decreased by the ratio of the decreased fuel efficiency value divided by the calculated fuel efficiency value;
              This shall not compensate for technical elements that would effectively require a vehicle to be excluded from the interpolation family.
              3.2.4. Fuel consumption, fuel efficiency and CO2 calculations for individual vehicles in a road load matrix family
              The CO2 emissions and the fuel efficiency/fuel consumption for each individual vehicle in the road load matrix family shall be calculated according to the interpolation method described in paragraphs 3.2.3.2.3. to 3.2.3.2.5. inclusive of this annex. Where applicable, references to vehicle L and/or H shall be replaced by references to vehicle LM and/or HM respectively.
              3.2.4.1. Determination of fuel consumption, fuel efficiency and CO2 emissions of vehicles LM and HM
              The mass of CO2 emissions  of vehicles LM and HM shall be determined according to the calculations in paragraph 3.2.1. of this annex for the individual cycle phases p of the applicable WLTC and are referred to as  and respectively. Fuel consumption and fuel efficiency for individual cycle phases of the applicable WLTC shall be determined according to paragraph 6. of this annex and are referred to as FCLM,p, FCHM,p, FELM,p and FELM,p respectively.
3.2.4.1.1. Road load calculation for an individual vehicle
              The road load force shall be calculated according to the procedure described in paragraph 5.1. of Annex B4.
3.2.4.1.1.1. Mass of an individual vehicle
              The test masses of vehicles HM and LM selected according to paragraph 4.2.1.4. of Annex B4 shall be used as input.
              TMind, in kg, shall be the test mass of the individual vehicle according
