selects for testing the two vehicles, which the service considers to have the highest and the lowest CO2 emissions respectively.  The measurements are performed as described in paragraph 5. and Annex 6.  If the manufacturer's data for these two vehicles falls within the tolerance limits described in paragraph 5.5., the CO2 emissions declared by the manufacturer for all members of the vehicle family can be used as type-approval values.  If the manufacturer's data do not fall within the tolerance limits, the results according to the method described in paragraph 5.5. are used as type-approval values and the technical service shall select an appropriate number of other family members for additional tests

     8. SPECIAL PROVISIONS

      In the future, vehicles with special energy efficient technologies may be offered which could be submitted to complementary testing programmes.  These would be specified at a later stage which can be claimed by the manufacturer in order to demonstrate the advantages of the solution.

     9. CONFORMITY OF PRODUCTION

     9.1. Vehicles approved to this Regulation shall be so manufactured as to conform to the type approved vehicle.

     9.2. So as to verify that the conditions set out in paragraph 9.1. are complied with, appropriate production checks shall be carried out.

     9.3. Vehicles powered by an internal combustion engine only:

     9.3.1. As a general rule, measures to ensure the conformity of production with regard to CO2 emissions from vehicles are checked on the basis of the description in the type approval certificate conforming to the model in Annex 4 of this Regulation.

      The control of production conformity is based on an assessment made by the competent authority of the manufacturer's auditing procedure in order to ensure conformity of the vehicle type with respect to the emission of CO2.

      If the authority is not satisfied with the standard of the manufacturer's auditing procedure, they may require that verification tests be carried out on vehicles in production.

     9.3.1.1. If a measurement of the emissions of CO2 must be carried out on a vehicle type that has had one or several extensions, the tests will be carried out on the vehicle(s) available at the time of the test (vehicle(s) described in the first document or in subsequent extensions).

        9.3.1.1.1. Conformity of the vehicle for the CO2 test.

        9.3.1.1.1.1. Three vehicles are randomly taken in the series and are tested according to the procedure as described in Annex 6.

        9.3.1.1.1.2. If the authority is satisfied with the production standard deviation given by the manufacturer, the tests are carried out according to paragraph 9.3.2.

         If the authority is not satisfied with the production standard deviation given by the manufacturer, the tests are carried out according to paragraph 9.3.3.

        9.3.1.1.1.3. The production of a
