# Commission Implementing Decision (EU) 2017/785 of 5 May 2017 on the approval of efficient 12 V motor-generators for use in conventional combustion engine powered passenger cars as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance), Division: Formula 1

Extent: E+W+S+N.I.

η MG i = 60 × U i × I i 2π × M i × n i × 100 All efficiency measurements are to be performed consecutively at least five (5) times. The average of the measurements at each operating point ( η MG i – ) shall be calculated.
The efficiency of the motor generator (ηMG) shall be calculated in accordance with the following Formula 2:
