the dilution air bags. Correction shall be carried out according to paragraph 3.2.1.1. of this annex.
              3.2.3. Fuel consumption, fuel efficiency and CO2 calculations for individual vehicles in an interpolation family
              3.2.3.1. Fuel consumption, fuel efficiency and CO2 emissions without using the interpolation method (i.e. using vehicle H only)
              The CO2 value, as calculated in paragraphs 3.2.1. to 3.2.1.1.2. inclusive of this annex, and fuel efficiency/fuel consumption, as calculated according to paragraph 6. of this annex, shall be attributed to all individual vehicles in the interpolation family and the interpolation method shall not be applicable.
              3.2.3.2. Fuel consumption and CO2 emissions using the interpolation method
              The CO2 emissions and the fuel consumption for each individual vehicle in the interpolation family may be calculated according to paragraphs 3.2.3.2.1. to 3.2.3.2.5. inclusive of this annex.
              3.2.3.2.1. Fuel consumption and CO2 emissions of test vehicles L and H
              The mass of CO2 emissions, , and  and its phases p,  and , of test vehicles L and H, used for the following calculations, shall be taken from step 9 of Table A7/1.
              Fuel consumption values are also taken from step 9 of Table A7/1 and are referred to as FCL,p and FCH,p.
              3.2.3.2.2. Road load calculation for an individual vehicle
              In the case that the interpolation family is derived from one or more road load families, the calculation of the individual road load shall only be performed within the road load family applicable to that individual vehicle.
              3.2.3.2.2.1. Mass of an individual vehicle
              The test masses of vehicles H and L shall be used as input for the interpolation method.
              TMind, in kg, shall be the test mass of an individual vehicle according to paragraph 3.2.25. of this Regulation.
              If the same test mass is used for test vehicles L and H, the value of  shall be set to the mass of test vehicle H for the interpolation method.
              3.2.3.2.2.2. Rolling resistance of an individual vehicle
              3.2.3.2.2.2.1. The actual RRC values for the selected tyres on test vehicle L, RRL, and test vehicle H, RRH, shall be used as input for the interpolation method. See paragraph 4.2.2.1. of Annex B4.
              If the tyres on the front and rear axles of vehicle L or H have different RRC values, the weighted mean of the rolling resistances shall be calculated using the equation in paragraph 3.2.3.2.2.2.3. of this annex.
              3.2.3.2.2.2.2. For the tyres fitted to an individual vehicle, the value of the rolling resistance coefficient RRind shall be set to the RRC value of the applicable tyre energy efficiency class according to Table A4/2 of Annex B4.
              In the case where individual vehicles can be supplied with a complete set of standard wheels and tyres and
