energy consumption shall be so designed, constructed and assembled as to enable the vehicle, in normal use, despite the vibrations to which it may be subjected, to comply with the provisions of this Regulation.

        5.2. Description of tests for vehicles powered by an internal combustion engine only

        5.2.1. The emissions of CO2 and fuel consumption shall be measured according to the test procedure described in Annex 6.  Vehicles which do not attain the acceleration and maximum speed values required in the test cycle must be operated with the accelerator control fully depressed until they once again reach the required operating curve.  Deviations from the test cycle must be recorded in the test report.

        5.2.2. For CO2 emissions the results of the test must be expressed in grams per kilometre (g/km) rounded to the nearest whole number.

        5.2.3. Fuel consumption values must be expressed in litres per 100 km (in the case of petrol, LPG or diesel) or in m3 per 100 km (in the case of NG), and are calculated according to paragraph 1.4.3. of Annex 6 by the carbon balance method using the measured emissions of CO2 and the other carbon related emissions (CO and HC).  The results will be rounded to the first decimal place.

        5.2.4. For the purpose of the calculation mentioned in paragraph 5.2.3., the fuel consumption shall be expressed in appropriate units and the following fuel characteristics shall be used:

            (1) density: measured on the test fuel according to ISO 3675 or an equivalent method.  For petrol and diesel fuel the density measured at 15 ºC will be used; for LPG and natural gas a reference density will be used, as follows:

             0.538 kg/litre for LPG
             0.654 kg/m3 for NG [3]/

            (2) hydrogen-carbon ratio:  fixed values will be used which are:

             1.85 for petrol

             1.86 for diesel fuel
             2.525 for LPG
             4.00 for NG

        5.3. Description of tests for vehicles powered by an electric power train only

        5.3.1. The technical service in charge of the tests conducts the measurement of the electric energy consumption according to the method and test cycle described in Annex 7 to this Regulation.

        5.3.2. The technical service in charge of the tests conducts the measurement of the electric range of the vehicle according to the method described in Annex 9.

         The electric range measured by this method is the only one which may be included in sales promotional material.

        5.3.3. The result of the electric energy consumption must be expressed in Watt hours per kilometre (Wh/km) and the range in km, both rounded to the nearest whole number.

        5.4. Description of tests for vehicles powered by a hybrid electric power train

        5.4.1. The technical service in charge of the tests
