For the purpose of the calculation referred in point 2.2.3., the fuel consumption shall be expressed in appropriate units and the following fuel characteristics shall be used: (a) density: measured on the test fuel according to ISO 3675:1998 or an equivalent method. For petrol and diesel fuel, the density measured at 288,2 K (15 °C) and 101,3 kPa shall be used; for LPG, natural gas, H 2 NG and hydrogen, a reference density shall be used, as follows: 0,538 kg/litre for LPG; 0,654 kg/m 3 for NG ( 1 ) / biogas; Equation 7-1: for H 2 NG (with A being the quantity of NG/biomethane in the H 2 NG mixture, expressed in percent by volume for H 2 NG); 0,084 kg/m 3 for hydrogen (b) hydrogen-carbon ratio: fixed values will be used, as follows: C 1 : 1,89 O 0,016 for E5 petrol; C 1 : 1,86 O 0,005 for diesel; C 1 : 2525 for LPG (liquefied petroleum gas); C 1 : 4 for NG (natural gas) and biomethane; C 1 : 2,74 O 0,385 for ethanol (E85). 2.3. Description of tests for vehicles powered by an electric powertrain only 2.3.1. The technical service in charge of the tests shall conduct the measurement of the electric energy consumption according to the method and test cycle described in Appendix 6 to Annex II. 2.3.2. The technical service in charge of the tests shall measure the electric range of the vehicle according to the method described in Appendix 3.3. 2.3.2.1. The electric range measured by this method shall be the only one referred to in promotional material. 2.3.2.2. Category L1e vehicles designed to pedal referred to in Article 2(94) shall be exempted from the electric range test. 2.3.3. Electric energy consumption shall be expressed in Watt hours per kilometre (Wh/km) and the range in kilometres, both rounded to the nearest whole number. 2.4. Description of tests for vehicles powered by a hybrid electric powertrain 2.4.1. The technical service in charge of the tests shall measure the CO 2 emissions and the electric energy consumption according to the test procedure described in Appendix 3. 2.4.2. The test results for CO 2 emissions shall be expressed in grams per kilometre (g/km) rounded to the nearest whole number. 2.4.3. The fuel consumption, expressed in litres per 100 km (in the case of petrol, LPG, ethanol (E85) and diesel) or in kg and m 3 per 100 km (in the case of NG/biomethane, H 2 NG and hydrogen), shall be calculated according to point 1.4.3. of Annex II by the carbon balance method using the CO 2 emissions measured and the other carbon-related emissions (CO and HC). The results shall be rounded to the first decimal place. 2.4.4. For the purpose of the calculation referred to in point 2.4.3., the prescriptions and reference values of point 2.2.4. shall apply. 2.4.5. If applicable, electric energy consumption shall be expressed in Watt hours per kilometre (Wh/km), rounded to the nearest whole number. 2.4.6. The technical service in charge of the tests shall measure the electric range of the vehicle according to the method described in Appendix 3.3. The result shall be expressed in kilometre, rounded to the nearest whole number. The electric range measured by this method shall be the only one referred to in promotional material and used for the calculations in Appendix 3. 2.5. Interpretation of test results 2.5.1. The CO 2 value or the value of electric energy consumption adopted as the type-approval value shall be that declared by the manufacturer if this is not exceeded by more than 4 percent by the value measured by the technical service. The measured value may be lower without any limitations. In the case of vehicles powered by a combustion engine only which are equipped with periodically regenerating systems as defined in Article 2(16), the results are multiplied by the factor K i obtained from Appendix 13 to Annex II before being compared with the declared value. 2.5.2. If the measured value of CO 2 emissions or electric energy consumption exceeds the manufacturer’s declared CO 2 emissions or electric energy consumption value by more than 4 percent, another test shall be run on the same vehicle. Where the average of the two test results does not exceed the manufacturer’s declared value by more than 4 percent, the value declared by the manufacturer shall be taken as the type-approval value. 2.5.3. If, in the event of another test being run, the average still exceeds the declared value by more than 4 percent, a final test shall be run on the same vehicle. The average of the three test results shall be taken as the type-approval value. 3. Modification and extension of approval of the approved type 3.1. For all approved types, the approval authority that approved the type shall be notified of any modification of it. The approval authority may then either: 3.1.1. consider that the modifications made are unlikely to have an appreciable adverse effect on the CO 2 emissions and fuel or electric energy consumption values and that the original environmental performance approval will be valid for the modified vehicle type with regard to the environmental performance, or 3.1.2. require a further test report from the technical service responsible for conducting the tests in accordance with point 4. 3.2. Confirmation or extension of approval, specifying the alterations, shall be communicated by the procedure referred to in Article 35 of Regulation (EU) No 168/2013. 3.3. The approval authority that grants the extension of the approval shall assign a serial number for such an extension according to the procedure set out in Article 35 of Regulation (EU) No 168/2013. 4. Conditions of extension of vehicle environmental performance type-approval 4.1. Vehicles powered by an internal combustion engine only, except those equipped with a periodically regenerating emission-control system A type-approval may be extended to vehicles produced by the same manufacturer that are of the same type or of a type that differs with regard to the following characteristics in Appendix 1, provided the CO 2 emissions measured by the technical service do not exceed the type-approved value by more than 4 percent: 4.1.1. reference mass; 4.1.2. maximum authorised mass.; 4.1.3. type of bodywork; 4.1.4. overall gear ratios; 4.1.5. engine equipment and accessories; 4.1.6. engine revolutions per kilometre in highest gear with an accuracy of +/– 5 %. 4.2. Vehicles powered by an internal combustion engine only and equipped with a periodically regenerating emission-control system. The type-approval may be extended to vehicles produced by the same manufacturer that are of the same type or of a type that differs with regard to the characteristics in Appendix 1, as referred to in points 4.1.1. to 4.1.6., without exceeding the propulsion family characteristics of Annex XI, provided the CO 2 emissions measured by the technical service do not exceed the type-approved value by more than 4 percent, where the same K i factor is applicable. The type-approval may also be extended to vehicles of the same type, but with a different K i factor, provided the corrected CO 2 value measured by the technical service does not exceed the type-approved value by more than 4 percent. 4.3. Vehicles powered by an electric powertrain only Extensions may be granted after agreement with the approval authority. 4.4. Vehicles powered by a hybrid electric powertrain The type-approval may be extended to vehicles of the same type or of a type that differs with regard to the following characteristics in Appendix 3 provided the CO 2 emissions and the electric energy consumption measured by the technical service do not exceed the type-approved value by more than 4 percent: 4.4.1. reference mass; 4.4.2. maximum authorised mass; 4.4.3. type of bodywork; 4.4.4. type and number of propulsion batteries. Where multiple batteries are fitted, e.g. to extend the range extrapolation of the measurement, the base configuration, taking into account the capacities and the way in which the batteries are connected (in parallel, not in series), shall be deemed sufficient. 4.5. Where any other characteristic is changed, extensions may be granted after agreement with the approval authority. 5. Special provisions Vehicles produced in the future with new energy-efficient technologies may be subject to complementary test programmes, to be specified at a later stage. Such testing will enable manufacturers to demonstrate the advantages of the technologies. ( 1 ) Mean value of G20 and G25 reference fuels at 288,2 K (15 °C).
