Cars to come with star rating for fuel efficiency

    While we have energy efficiency rating on electric appliances, we are yet to see any rating on fuel efficiency ratings on automobiles like the developed western markets. Several countries have the rating system and the regulatory authorities like U.S has EPA which certifies the automobile’s efficiency.

    Now according to a report in The Economic Times, some preliminary estimates have found that in India, only 9 percent to 16 percent car models are energy efficient. It was reported that a consultation paper recently released by the Bureau of Energy Efficiency (BEE) to set fuel efficiency standards for car models pointed out that the average weight of cars sold every year in the country was increasing and there has been a three-fold rise in the number of cars over the last decade. It was mentioned that according to the paper, "If the trend continues, in 2020, it would increase to over 5.5 million per year and the total stock in the country would exceed 45 million. The annual fuel requirement would then be in excess of 25 million tonnes of oil equivalent." It revealed that with the increasing weight of cars, the fuel consumption per 100 km was not reducing.

    The report stated that preliminary estimates made in the paper state that of the total 330 car models in India, 32 fell within 5-star category-assumed as the most fuel efficient while 52 fell in 4-star category, comparatively less fuel efficient. As per the BEE's assumption, cars in 5-star category are those which roughly consume up to 7 litres of fuel for 100 km. Those consuming between 7 and 9 litres fall in 4-star category whereas those between 9 and 11 litres per 100 km belong to the 3-star category. Cars consuming 12 litres of fuel for 100 km and beyond are in the 1-star category. It was also reported that primary findings suggest that 105 car models fall in the 3-star category while 69 models belong to the 2-star category. In the 1-star category, there are 72 models. Thus, there are more number of less fuel efficient cars than efficient ones.

    It was mentioned in the report that considering the market of car models falling in different star categories as per BEE's preliminary assumption in thousands, the sale of 1-star and 5-star models assumes the lowest between 62 and 72 vehicles per 1,000 vehicles. The sale of four-star car models is the highest at 625 in 1,000 vehicles. However, the 2- and 3-star categories are selling at 535 to 585 cars among 1,000 vehicles each, making it difficult for the country to meet the fuel efficiency target. "In view of the expected tripling of cars in the next decade and considering national import dependence on petroleum in excess of 70 percent, besides the declining urban air quality due to increasing fuel consumption, it is important to provide strong signals to both car manufacturers and users of the need to reduce the average fuel consumption of new cars," the paper stated, according to the report.

    The report mentioned that the BEE now aims to introduce medium and long term fuel consumption standards for new cars which would provide a regulatory signal to manufacturers to continuously reduce the average fuel consumption of cars sold by them over the next 10-year period. "Similarly, labelling of cars in the market will help consumers know the fuel consumption of a car model and the relative fuel consumption of another model in the same weight category," said the BEE paper.

    With this technique, BEE hopes to achieve the reduction in fuel consumption per 100 km from the present 6 litres to 5.1 litres by 2016 and up to 4.4 litres per 100 km by 2021, the report stated.

    Grande Punto 1.3
    Punto and Linea fall in 5-star category. So no issues. :)

    The differentiating criteria doesn't make much sense to me. To fall in the 5 star category a car needs to achieve 7l/100km =14.2 kmpl . That's not an impressive figure, by far. Especially for diesels.

    9l/100 = 11kmpl is 4 stars !

    That's really weird.

    Guru as usual, they are putting a loop hole here so that any manufactures can attain a 5 star rating easily. Another big nonsense on the papers. :punch

    May be the above calculation criteria is for Petrol Vehicles. There might be another calculation for Diesels. There cannot be the same calculation for a petrol and diesel for any model from any single manufacturer.
