 I. GENERAL
 On 15 June 1979* under the Community 's programme for energy saving, the
 Commission forwarded to the Council a proposal for a Resolution on new
 lines of action by the European Community in the field of energy saving ( l ).
 In item 3.1 of this proposal it is agreed that "voluntary indicative targets
 for the fuel consumption of motor cars and light vans should be established
 at Community level in cooperation with the automobile industry" and that the
 Commission should aocelerate "the completion of the remaining technical work
 to develop a standard method of measuring fuel consumption by vehicles ".
 The importance of a Community method of measuring the fuel consumption of
 a vehicle is beyond question not only as regards the monitoring of the
 abovementioned targets for the reduction of consumption but also as regards , ,
 the supply of objective information to customers and users .
 Negotiations sire under way with the motor-vehicle manufacturers with a view
 to reaching agreement on voluntary measures by the latter to restrict fuel
 consumption . As regards the method of measuring this consumption, the Com­
 mission is in a position to put forward a proposal for a Direotive , sinoe
                                                         *
 the basis of this essentially technical text is already available .
                                       *                        •»
  At the same time , the Commission is likewise in a position to put forward
  a proposal for a Directive on a method of measuring the engine power of
  motor vehicles . These two proposed Directives are part of the procedure for
  EEC type-approval of motor vehicles and their trailers which was the sub­
  ject of Council Directive 70/156/EEC of 6 February 1970 (2 ) and in respect
  of which a proposed amendment was forwarded to the Council by the Commissign
– in January 1977 (3 )» In adopting these two proposed Directives , the Council
  must therefore take prior or simultaneous measures to adopt the corresponding
                                                                        • •/ • •

amendments to Directive 70/I56/ ESC . The sections in question are 3.2.5 and
3.2.10 , Annex I (minor amendments being required in respect of Notes ( s )
and ( t ) of this same annex ) and 3*2.1 and 3.2.3 , Annex II . Lastly, it should
be emphasized that , in formulating these two proposed Directives , the Commis­
sion took as its basis work already carried out in this area by the Geneva-
based Economic Commission for Europe – a fact which , as far as trade is
concerned , must be an added advantage , since a very large number of countries
are represented in this organization *
II . COMMENTS , ON THE TWO PROPOSED DIRECTIVES
As regards the measurement of fuel consumption , the field of application
is limited to motor vehicles of Catsgof-y      (l )» As regards the measurement
of engine power ? the field of application covers notor vehicles of Categories
M ( l ) and N (l ) ( Artioles 1 and items 2 of the annexes ).
Article 2 in each case incorporates into the ESC type-approval procedure the
provisions relating to methods of measuring fuel consumption and engine power
respectively . In the case of certain Member States which do not at present
have a national type-approval procedure it has 'b sen necessary to introduce
provisions under which the use in these countries of vehicles complying with
the requirements of the two Directives can be guaranteed .
Article 3 in each case lays down the procedure for the adaptation to tech­
nical progress of the requirements of the annexes , This procedure is set out
in Article 13 of Directive- 1Q/l^6/ESC on the EEC type-approval cf motor vehic­
les and their trailers .
Article 4 in each case lays down the deadline for the entry into force of
the provisions necessary in order to comply with the two Directives .
Lastly , the Commission must be informed within a reasonable period of any
draft provisions drawn up bjf the Member States in the fields covered by the
two Directives , so as to enable it to put forward any comments it may wish
to make on these draft provisions ( Articles 4 « paragraphs 2 ).
                                                                           0 »! v •

        For the purposes of this Directive ,
3.1 .   "Net power" means the power obtained on the test bed at the end of the
        crankshaft or its equivalent at the corresponding engine speed with the
        auxiliaries listed in table 1 . If the power measurement can be carried
        out with a mounted gear-box only, the efficiency of the gear-box shall
        be taken into account .
3.2.    "Available power" means that part of the net power, which is calculated
        according to the provisions of appendix 4)

        facturer for a particular application.            '

 Notes to the Statement of the Results of Calculation of Available Power.
       1/   Available Pover – method of determination :    The smilable power is th<?
 cUffervnce between the net power determined according to the method described in
 paraf-raph 5 . above ana the cun of the pover of the auxiliaries other than those
 specified, in table 1 ( paragraph 5.1-1.2 . above ) and in continuous operation.
      2J    Power to be included for the variouc auxiliaries
      This note gives a non-exhaustive list of auxiliaries which can be fitted to
the vehicle and indicates the power to be taken into account in calculating* the
available power as defined in note l/ above .                                 '      ■ . ■
      Air compressor or other sources of pover for the braking device . Only the
power in the unloaded condition shall be taken into account in calculating the
available power .
      Power steering- compressor.     Since this operates intermittently, only the
minimum power absorbed will be t^ken into account .
      Suspension compressor.    Since this operates intermittently, only the minimum ,
power absorbed will be taken into account .
      Air–conditioning1 or refrigerating system *    The rated power absorbed by this
equipment will be taken into account -.                      -   -

      Mfchanieal equipment taking power directly or indirectly from the engine of
the vehicle and in continuous operation while the vehicle is moving
( cesent-cixer etc .).   The nominal power absorbed by such equipment will be taken
into account .      "
            The maximum available power and torque and corresponding engine speeds
are determined by considering the horizontal tangent where applicable .
