Govt proposes BS-VII norms for passenger cars from April 2029, adds brake, tyre and EV battery-durability rules
Our read
The draft is likely to be notified with its 1 April 2029 BS-VII start intact, while the brake-particle and battery-durability details are eased or phased.
For operators
The Ministry of Road Transport and Highways' draft would bring BS-VII to new passenger cars from 1 April 2029, so car retailers and dealer groups should expect compliance-driven model and pricing changes and plan stock around the transition, with comments open for 30 days.
Watch
Final notification keeping the 75% battery-retention rule past the 30-day comment window would mean EV makers must warrant packs and cell suppliers face tighter specs.

The report,
The Ministry of Road Transport and Highways has invited public comments for 30 days on a draft that adds brake-particle and tyre-abrasion limits from April 2031. Passenger cars would face BS-VII exhaust limits from 1 April 2029, alongside battery-durability rules for EVs.
- Pure EVs3 mg per km
- Other powertrains7 mg per km
Reported figures
From the report. Source details below
| Brake-particle limit, pure EVs from April 2031: | 3 mg per km |
|---|---|
| Brake-particle limit, other powertrains from April 2031: | 7 mg per km |
| EV battery retention, first five years or 100,000 km: | 75% |
Why it matters to operators
The draft sets BS-VII from 1 April 2029, brake-particle caps from April 2031 and 75% EV battery retention over five years or 100,000 km, which points to higher compliance spending for carmakers, though final terms may shift after the 30-day comment window.
What to watch next
- Industry body comments on lead time to 1 April 2029
- Whether the 2031 brake-particle caps of 3 mg per km and 7 mg per km survive the final text
- Any relaxation of the NOx 60 mg per km petrol limit in the notified version
- Announcements on fuel quality and test-lab readiness for BS-VII
