Annex 8

    METHOD OF MEASURING THE EMISSIONS OF CARBON DIOXIDE, FUEL CONSUMPTION AND THE ELECTRIC ENERGY CONSUMPTION OF VEHICLES POWERED BY A HYBRID ELECTRIC POWER TRAIN

       1. INTRODUCTION

       1.1. This annex defines the specific provisions regarding type-approval of a hybrid electric vehicle (HEV) as defined in paragraph 2.12.2. of this Regulation.

       1.2. As a general principle for the tests, hybrid electric vehicles shall be tested according to the principles applied to vehicles powered by an internal combustion engine only (Annex 6), unless modified by this annex.

       1.3. OVC vehicles (as categorised in paragraph 2. to this annex) shall be tested according to condition A and to condition B.

        The test results under both conditions A and B and the weighted average shall be reported in the communication form described in Annex 4.

       1.4. Driving cycles and gear shifting points

       1.4.1. For vehicles with a manual transmission the driving cycle described in appendix 1 of Annex 4 to Regulation No. 83 in force at the time of approval of the vehicle shall be used, including the prescribed gear shifting points.

       1.4.2. For vehicles with a special gear shifting strategy the gear shifting points prescribed in appendix 1 of Annex 4 to Regulation No. 83 are not applied.  For these vehicles the driving cycle specified in paragraph 2.3.3. of Annex 4 to Regulation No. 83 in force at the time of approval of the vehicle shall be used.  Concerning gear shifting points, these vehicles shall be driven according to the manufacturer's instructions, as incorporated in the drivers' handbook of production vehicles and indicated by a technical gear shift instrument (for drivers information).

       1.4.3. For vehicles with an automatic transmission the driving cycle specified in paragraph 2.3.3. of Annex 4 to Regulation No. 83 in force at the time of approval of the vehicle shall be used.

       1.4.4. For vehicle conditioning a combination of the Part One and/or Part Two cycles of the applicable driving cycle shall be used as prescribed in this annex.

        (a) also known as "externally chargeable"

        (b) also known as "not externally chargeable"

       3. EXTERNALLY CHARGEABLE (OVC HEV) WITHOUT AN OPERATING MODE SWITCH

       3.1. Two tests shall be performed under the following conditions:

        Condition A: test shall be carried out with a fully charged electrical energy/power storage device.

        Condition B: test shall be carried out with an electrical energy/power storage device in minimum state of charge (maximum discharge of capacity).
