With factors like exhaust emissions, non-exhaust emissions, battery durability and lifetime requirements (in terms of mileage and lifetime) as the key requirements, vehicles complying with BS 7 emission regulations will see a considerable rise in onboard controllers. 
The commercial vehicles will be particularly subject to a doubling of controllers onboard as the new emission regulations kick in the next two to three years, mentioned a technology chief of an automobile company in India recently. 
The number of controllers will double in a commercial vehicle from 10 to 20, he explained. He drew attention to the move up to Euro 7 emission norms in Europe and stated, “The BS 7 emission norms in India are loosely based on the Euro 7 emission regulations that come into effect in Europe in 2025.”  
The Euro 7 emission regulations in Europe will come into force for passenger vehicles from 1 July 2025. The Euro 7 emission regulations for commercial vehicles will come into force from 1 July 2027. 
The BS 7 emission regulations draft is out, mentioned an auto components industry leader. “The emission regulations, like in Europe, are expected to be enforced in a staggered manner,” he added. 
The government is expected to announce the BS 7 regulations for passenger vehicles and two-wheelers in the middle of next calendar year. These would closely follow the RDE norms that came into force from middle of last calendar year. 
The effect of BS & emission norms is expected to be considerable in terms of price escalation in vehicles.
