        1.4. Vehicle classification
        PEVs shall be classified as Class 3 vehicles. The applicable test cycle for the Type 1 test procedure shall be determined according to paragraph 1.4.2. of this annex based on the corresponding reference test cycle as described in paragraph 1.4.1. of this annex.
        
        1.4.1. Reference test cycle
        
        1.4.1.1. The Class 3 reference test cycles are specified in paragraph 3.3. of Annex B1.
        
        1.4.1.2. For PEVs, the downscaling procedure, according to paragraphs 8.2.3. and 8.3. of Annex B1, may be applied on the test cycles according to paragraph 3.3. of Annex B1 by replacing the rated power with maximum net power according to UN Regulation No. 85. In such a case, the downscaled cycle is the reference test cycle.

        1.4.2.1. Applicable WLTP test cycle
        The reference test cycle according to paragraph 1.4.1. of this annex shall be the applicable WLTP test cycle (WLTC) for the Type 1 test procedure. In the case that paragraph 9. of Annex B1 is applied based on the reference test cycle as described in paragraph 1.4.1. of this annex, this modified test cycle shall be the applicable WLTP test cycle (WLTC) for the Type 1 test procedure
        1.4.2.2. Applicable WLTP city test cycle
        The Class 3 WLTP city test cycle (WLTCcity) is specified in paragraph 3.5. of Annex B1.
        
        3.5. WLTC city cycles
        PEVs shall be tested using the appropriate Class 3a and Class 3b WLTC and WLTC city cycles (see Annex B8).
        The WLTC city cycle consists of the low and medium speed phases only.
        
        Noi siamo Class 3a perchè vmax < 120 km/h
        
        3.3.1. Class 3a cycle
        
        A 3-phase Class 3a cycle shall consist of a low phase (Low3), a medium phase (Medium3a) and a high phase (High3a)
        NON ci intessa perchè è per i livelli di emissione del GIAPPONE
        
        3.3.1.1. A complete Class 3a cycle shall consist of a low phase (Low3), a medium phase (Medium3a), a high phase (High3a) and an extra high phase (Extra High3).

        3.4. PEVs
        3.4.1. General requirements
        The test procedure to determine the pure electric range and electric energy consumption shall be selected according to the estimated pure electric range (PER) of the test vehicle from Table A8/3. In the case that the interpolation method is applied, the applicable test procedure shall be selected according to the PER of vehicle H within the specific interpolation family
