              4.4. Calculation of brake specific fuel consumption
              The cycle work needed for the calculation of the brake specific fuel consumption shall be determined in accordance with paragraph 7.8.6. of Annex 4.
              4.4.1. WHTC
              The brake specific fuel consumption ef (g/kWh) shall be calculated as follows:
              Where:
              qmf, cold  is the fuel mass of the cold start test, g/test
              qmf, hot  is the fuel mass of the hot start test, g/test
              Wact, cold is the actual cycle work of the cold start test, kWh
              Wact, hot  is the actual cycle work of the hot start test, kWh
              4.4.2. WHSC
              The brake specific fuel consumption ef (g/kWh) shall be calculated as follows:
              Where:
              qmf is the fuel mass, g/test
              Wact is the actual cycle work, kWh

                   Annex 12 ‑ Appendix 1 Provisions on CO2 emissions and fuel consumption for extension of a type approval for a vehicle type-approved under this Regulation with a reference mass exceeding 2,380 kg but not exceeding 2,610 kg
A.1.1.  Introduction
              A.1.1.1. This appendix sets out the provisions and test procedures for reporting CO2 emissions and fuel consumption for extension of type approval for a vehicle type-approved under this Regulation to a vehicle with a reference mass exceeding 2,380 kg but not exceeding 2,610 kg.
A.1.2.  General requirements
              A.1.2.1. In order to receive an extension of a type-approval for a vehicle in respect of its engine type-approved under this Regulation to a vehicle with a reference mass exceeding 2,380 kg but not exceeding 2,610 kg, the manufacturer shall meet the requirements relating to the measurement of CO2 emissions and fuel consumption established by the type 1 emissions test procedures set out in Annex B6 to UN Regulation No. 154 with only speed trace and RCB corrections. The CO2 emissions shall be determined in accordance with table A6/2 of that annex not taking into account the criteria emission test results, where the vehicle during testing shall apply no AES and be considered as VH. The test reports specified in Appendix 1, Part I until paragraph 2.1. inclusive, and Appendix 2 to Annex A1 of UN Regulation No. 154, shall be submitted to the type approval authorities including the results of pollutant emissions.

              The manufacturer shall provide the type approval authority with a signed declaration that all variants and versions for which this extension is requested are in conformity with the type-approval emission requirements in this Regulation and that the type 1 test was performed in compliance with the previous paragraph.

              For dedicated compression ignition engines fuelled with ethanol (ED95), a fixed carbon-hydrogen-oxygen ratio shall be used for the purposes of calculating fuel consumption values, which shall be C1H2.92O0.46.
