Yes, you are right. It will be ARAI who will be the body that will be testing models for FE and issuing certifications one the law is passed.

God knows what silly methods they choose to test cars and give out FE that is hardly met by an average customer on the road. Find out surprising that manufacturers boast with those figures.

High time they get down to real time FE testing and publishing.

Default Re: Government wants corporate average fuel economy of 18.2 kmpl

The Government needn't bother. In India, only fuel-efficient cars sell. Gas guzzlers don't. Fuel economy is among the topmost priorities of customers in the mass market segment (that's over 99% of cars on our roads).

I prefer not to. For one, it's too hot most of the year in Mumbai. Second, I practice 60-second turbo idling in my cars. Third, in my Civic, I need to switch the stereo off before restarting.

Not at all. CAFE is the average fuel economy that the Government wants to impose on car manufacturers. Meaning, they can get away with a guzzler or two as long as they have other fuel-efficient cars.

Anyway, not like the homegrown SUVs are guzzlers. The Mahindra Scorpio has an ARAI rating of 15.37 kmpl.

Time for you to be happy . The varying excise duties (starting from 1.2L sub-4 meter cars) are in place for this reason only. You'll also see how big cars with big engines are taxed the highest.

That is one way of encouraging small cars. But, being excise duties, the auto-manufacturer passes off the duties onto the customer, most of whom, happily bear the burden of buying a mean big machine. This does not encourage innovation and technological improvement on the part of the manufacturers on a direct level.

However, if there is a system of penalties or a 'Green tax' exclusively on companies that do not meet the mileage benchmarks (for each category of cars), then maybe the companies will be forced to consider bringing out upgraded cars that do not cause much pollution or use less fuel. I agree that this is not simple. For example, one cannot levy a penalty on a car with bigger engine to a car with a smaller engine (but tuned better and gives less mileage) based on engine capacity alone. But, some meaningful benchmarks can sure be put in place to directly promote less-fuel guzzling cars.

Great news! Tin box car manufacturers will be very happy to make lighter weighing cars and laugh all the way to the bank. India's largest car manufacturer (by domestic market share) will sure be happy to toe the line with the kpl requirement.

**applaud. applaud**.

Govt doesn't feel the need to improve on the safety first.

Not one switches the engine off but cries out loud when fuel prices are increased.
Absolutely! It's funny how some of them rush to fuel bunks to save 60-100 rupees on fuel cost increase but will happily idle their engines at every signal. (some fools do it even when they're not using AC).

However, like GTO had mentioned, given the heat in the daytime, switching engine off may mean starting to sweat. In the evenings though, returning home, I always switch the engine off at the signal where I know I will be stranded for a while. Sometimes, twice on the same road (total stretch of <3 kms).

Switching off in the evening at signals where idling time will be >60 seconds is definitely worth. You won't be sweating too much either. (anyway, you're returning home and a little discomfort to save money & fuel, I assume, won't hurt).

Hare-brained idea.

On the one hand, we need stricter pollution control norms. On the other, the government insists on higher fuel efficiency.

Someone has to tell those babus and ministers who create these policies, that tighter emission control norms are invariably linked to lower fuel efficiency (as well as lower performance). As it is, plenty of folks around the country, in their quest for higher performance and FE, are tearing out and throwing away their pollution control devices (catcons, EGRs etc.), and no one cares (or even knows / understands).

The OEM's cannot really do that if they have to comply with BS regulations, but I suspect they'll find some loophole too, whereby the emission load will be higher but FE will go up enough to satisfy government rules. This would in all likelihood be in association with reduced safety standards to lighten weight too, with bodyshells that are less protective, and passive and active safety devices that are of poor quality (or even non-existent).

Hybrids -- coming soon?

Default Corporate Average Fuel Efficiency (CAFE) Standards for India

(Just found that there is already a thread on this topic. Request Mods to please merge this one.)

http://www.team-bhp.com/forum/indian...18-2-kmpl.html (Government wants corporate average fuel economy of 18.2 kmpl)

The Corporate Average Fuel Efficiency (CAFE) Standard is the average annual fuel efficiency for the fleet from the portfolio or range of each vehicle manufacturer. It is measured in terms of global warming causing carbon dioxide emissions. Only carbon dioxide emission is considered under the CAFE norms.The norms aim to reduce carbon footprints and calls for constant improvements in fuel efficiency of the manufacturer's fleet. (KYOTO protocol where the third world is crying hoarse over the emissions by developed countries).

The Govt of India has in 2014, assigned a target of 129.8 gms emission of carbon dioxide per km for the fiscal year 2018 and 113 gms of carbon dioxide per km for the fiscal year 2022, from the levels of 142 gms per km as in 2014. The manufacturer's fleet fuel efficiency for petrol vehicles should improve by April 2017 to 18.2 kmpl and for diesel 20.41 kmpl from the 16-18 kmpl earlier.

Failure to meet targets will make the manufacturers liable to be fined per extra emission of fiscal as is prevalent in Europe.
Credits will be awarded to manufacturers if they show better carbon dioxide footprints, that can be carried over as bonus points to the next year. Failure to meet target in the first year gives leeway to the manufacturer to correct its average , the next year.

The government says this will envisage savings of 20 million tonnes of fuel (petrol and diesel combined) by 2025. This will mean a gain of Rs 90,000 crores every year from when the norms are implemented, till 2025 .

The manufacturers now say that the CAFE norms which requires a double digit improvement in fuel economy can be only met with diesel engines, that the NGT and the SC are now decrying. Diesel vehicles emit less carbon dioxide and the diesel technology of Rudolf Diesel ensures a more complete fuel combustion during the combustion process, as compared to Otto Van's petrol engine technology. "Any manufacturer will have to have diesel share of at least 30 % in its fleet, or else it will have to struggle to meet the CAFE norms" according to Mr Kaushik Madhavan of Frost and Sullivan who talked to Economic Times.

Of course, the BS VI norms and the compatible clean, low-sulphur diesel when made available may be a game changer for diesel engines.

Here is a link for reference:
