New Delhi : Society of Indian Automobile Manufacturers (SIAM) on Aug 26 said its members will start disclosing the fuel efficiency ratings of their models comparable with their rivals from October 2010.

"SIAM has announced the scheme for voluntary fuel efficiency labelling for vehicles. This label, which will be implemented from October 1, would provide information to consumers on the comparative fuel efficiency of vehicles in different categories," SIAM President Pawan Goenka said at its annual convention here.

Automakers had voluntarily started disclosing the mileage of their own vehicles since 2009 and the government has geared up to make the process a mandatory one. "This will allow consumers to make the right choice of vehicles depending on their individual needs...It would encourage and promote lower fuel consumption," Goenka said. The industry was earlier reluctant to accept the mandatory disclosure of fuel efficiency level, but now it is prepared to do so, he added.

"The industry is willing and prepared to accept mandatory fuel efficiency standard. As a starting point, we invite the government to formally adopt the mandatory requirement," Goenka said. The government had said a mandatory fuel efficiency standard for auto makers will be introduced under the Energy Conservation Act by the Power Ministry.
