The Government of India is rumoured to be considering skipping a stage in emission norms and adopting BS-VI standards.

The authorities believe that oil companies can easily supply fuel necessary for BS-VI standards over the next few years. This is because the fuel quality specifications for BS-V and BS-VI standards are nearly the same. The authorities also believe that since local manufacturers such as Mahindra and Tata Motors have acquired some global carmakers, it would be easy for them to access the technology and knowhow necessary to update their engines in order to leapfrog one stage.

At present, 33 cities in India are following BS-IV norms, while the rest of the country is following BS-III standards. The entire country is to move to BS-IV standards by 2017. BS-V and BS-VI norms were to be adopted by 2020 and 2024, respectively. India is approximately 5 years behind Europe in emission norms. A leap from BS-IV to BS-VI will enable it to close this gap considerably.

However, the automobile industry believes that upgrades in emission norms and technology should be done in stages. Advancing the deadlines for the next stage in emission norms requires heavy investment. It is estimated that Rs. 50,000 crore would have to be invested in the four-wheeler segment for upgrading engines from BS-IV to BS-V standards.

If the oil companies have no problems, car manufacturers should not have a problem either. Its high time we did this and sync'ed with the rest of the world in emission and safety.

I hear the OMCs still have issues with BS-IV Diesel, forget BS-V. BS-IV is somewhat laxer than Euro-IV. So they must start producing BS-IV in adequate quantities so that the whole nation can get that, then switch Euro-IV spread across the land, before talking of BS-VI. I hear they are buying large quantities of BS-IV diesel from RIL.

If BS V and BS VI don't have a huge difference and if OMCs are okay with it then there's no problem and by 2020-2022, India should move to these standards. But the question is whether they can implement the BS-IV standard nationwide by 2017. I hope the new government should see this as an integral part of their transportation reforms. At least this will justify the never ending hike in excise duty.

Off topic: Is there any news on their plan in giving incentive for electric vehicle.

For reference purpose, what the Bharat Std quality of fuel means.
So what we are staring at is MAINLY reduced sulfur in the fuel.

Also attached is the current state of refiners with respect to the capacities and the fuel standards they manufacture.


From what I can gather, moving from Euro5 to Euro6 (and therefore from BS5 to BS6) is mainly engine change. The fuel remains the same.
NOx emissions need to be reduced.
Since the refineries are already on plan to invest so that they can produce BS5 by 2020, they will not raise any objections if Republic of India says we want BS6.

Automobile manufactures seem to agree to compress the timeline for the proposed Emission norms by a year. BS V in 2019 and BS VI in 2023.

Diesel Vehicles could see an increase of cost by 30 - S0k INR as it moves from BS IV to BS V and another 20-40K when the switch to BS VI is made.

Here in Bangalore , some Shell gas stations supply BS4 diesel while its BS 3 at others .

What are the implications on the engines ? The Ciaz is BS4 but the Shell Diesel that I fill is BS3 .
