With the new BS7 norms expected to be drafted soon, should one still buy a BS6 car? How quickly were BS4/BS5 cars phased out when BS6 norms were introduced?
The draft BS7 norms are still under discussion, and there is no confirmed implementation date yet. Even when they are finalised, there will be a lead time before they come into effect. When BS6 was introduced, there was a clear deadline, and manufacturers stopped producing BS4 cars well before the cut-off date, but existing BS4 cars already sold to customers remained perfectly legal to own and use.
The same principle will apply with BS7. Your BS6 car will remain fully road legal for its entire life. There is no forced scrappage or ban on existing vehicles. The only impact is that manufacturers will eventually stop producing BS6 cars and switch to BS7-compliant models.
There is no reason to delay your purchase because of BS7. If you need a car now, buy a BS6 car with confidence. The ownership experience, resale value and legality will not be affected by the introduction of BS7. The only reason to wait would be if you are specifically interested in a new model or technology that is expected to arrive with BS7, but for most buyers, that is not a practical reason to delay a purchase.
@autocar.india for someone based in Delhi wherein ICE vehicles are being phased out, does a BS6 vehicle make sense and be future proof for, say, 8-10 years?
