High & Low powered vehicle classification have been proposed by DHC based on PMR and Max. speed of the vehicle. This will determine what driving cycle(s) would be necessary for the test vehicle. Also depending on Passenger Cars or Goods vehicle the test mass would have to be set. In certain cases between cars and goods vehicles there is hardly any difference in test mass (e.g. for a low powered vehicle such as Gio there is only a 7 kg difference). In such cases, the test need not have to be run twice, if the difference is not exceeding 60 kg. This is logically inferred as the step in GTR test mass is 60 kg. This proposal may be discussed in meeting on 22nd May 2012.
