September 1, 2026 was the day India's electric bus and truck makers had been trying to postpone for a year. From that date, traction motors fitted to electric buses (M2/M3) and electric trucks (N2/N3) must be assembled in India to qualify for PM E-DRIVE subsidies — the scheme that underwrites more than 14,000 electric buses. The Society of Indian Automobile Manufacturers (SIAM) asked on July 22 for a seven-month reprieve to April 1, 2027. As the deadline arrived, no extension had been announced, leaving Tata Motors, Ashok Leyland's Switch Mobility, Olectra, JBM, PMI Electro and others to comply, absorb the subsidy loss, or slow deliveries. At the same time, the electric three-wheeler segment — India's most electrified — continues to boom, with Mahindra's three-wheeler sales up 42% in August. This report covers both sides of the commercial EV story.
What the Localisation Rule Requires
The Phased Manufacturing Programme (PMP) under PM E-DRIVE specifies that, for a vehicle to attract incentives, "manufacturing of traction motor which at least includes magnet fitment, fitment of rotor assembly into motor, fitment of stator assembly into motor, shaft fitment, bearing fitment, enclosure fitment, connectors fitment, cables fitment shall be domestically performed."
In practice, OEMs and their motor suppliers can still import the magnets, the laminated stator and rotor cores and the electronics — but the motor must be put together in an Indian plant. The rule does not ban imported motors; it removes the subsidy for vehicles that use them.
| Date | Event |
|---|---|
| September 29, 2024 | PM E-DRIVE notified with Rs 10,900 crore outlay; PMP localisation timeline set |
| April 4, 2025 | China imposes export controls on dysprosium, terbium and permanent magnets |
| September 1, 2025 | Original localisation deadline for e-bus/e-truck traction motors |
| September 30, 2025 | First deferral: deadline pushed to March 2026 |
| March 13, 2026 | Second deferral: imports of complete motors with rare-earth magnets allowed until August 31, 2026 |
| July 22, 2026 | SIAM seeks third extension to April 1, 2027 |
| August 11, 2026 | PM E-DRIVE extended to March 31, 2028; outlay raised to Rs 11,900 crore |
| September 1, 2026 | Localisation rule takes effect; no extension announced |
Why the Industry Wanted More Time
SIAM's case rested on rare earth magnets. India imports 100% of the sintered NdFeB magnets used in traction motors, and China — which makes more than 90% of the world's supply — has restricted exports of the heavy rare earths (dysprosium and terbium) that let magnets survive motor temperatures. Export licences have been slow and unpredictable. SIAM argued that extending the deadline would prevent production disruptions if supply constraints persisted and give component makers time to build local assembly capacity.
The Ministry of Heavy Industries' apparent reasoning for holding firm is that motor assembly — the step the rule mandates — does not itself depend on magnet supply. Whether magnets are imported into a Chinese motor plant or an Indian one, the magnet constraint is the same; what changes is where the value-added assembly work happens. Business Standard described e-CV makers as "in a quandary" on the eve of the deadline.
Who Is Affected, and How
| Manufacturer | Segment | Exposure to the rule | Likely response |
|---|---|---|---|
| Tata Motors | E-buses (Starbus, Ultra), e-trucks (Ace EV, Prima E) | Largest e-bus fleet under PM E-DRIVE tenders | Has domestic motor sourcing capacity via group suppliers; expected to comply fastest |
| Switch Mobility (Ashok Leyland) | E-buses (EiV 12, EiV 22) | High — a major PM E-DRIVE bidder | Localising motor assembly with suppliers; possible short-term delivery delays |
| Olectra Greentech | E-buses (BYD technology) | High — relies on imported BYD drivetrains | Most exposed; may need to establish local motor assembly or forgo subsidies |
| JBM Electric, PMI Electro | E-buses | High | Working with domestic motor suppliers |
| E-truck start-ups and importers | N2/N3 e-trucks | Moderate; e-truck subsidies are a smaller pool | Some may skip subsidy eligibility for near-term deliveries |
Fleet operators and state transport undertakings (STUs) should expect two consequences in the September-December quarter: renegotiated delivery schedules on existing tenders, and pricing that reflects either localised motors or lost subsidies.

Meanwhile, Electric Three-Wheelers Keep Climbing
The localisation rule does not apply to three-wheelers, and that segment is in rude health. August 2026 data:
- Mahindra three-wheeler sales (including the electric Treo, Zor Grand and the new Udo urban passenger e-3W) rose 42% year-on-year to 14,922 units in August 2026. Total Mahindra auto sales were 59,257 SUVs, up 50%.
- Tata Motors commercial vehicle sales grew 49% year-on-year in August, driven partly by the Ace EV last-mile van.
- Bajaj Auto total sales hit 5.35 lakh units in August, up 28%; its e-3W range now sells under the WEGO brand alongside the GoGo.
| FY2026 electric three-wheeler leaderboard | Units | Growth |
|---|---|---|
| Total e-3W market (L3 + L5) | 8,30,819 | +19% — first time past 800,000 |
| Mahindra Last Mile Mobility | 1,01,905 | Market leader in L5 |
| Bajaj Auto | 89,604 | +76%, No. 2 OEM |
| TVS Motor | Record year (King EV Max) | Third among organised OEMs |
Three-wheeler EV penetration stood at 60.77% in mid-August 2026 — by far the highest of any segment — and August's record 3,31,682 total EV registrations were driven substantially by e-rickshaws and L5 cargo and passenger autos. Our FY2026 e-3W report has the full-year breakdown.
PM E-DRIVE for Commercial EVs: Where the Money Is
The August 11 revision of PM E-DRIVE — extended to March 31, 2028 with a Rs 11,900 crore outlay — keeps the e-bus and e-truck components alive. The scheme supports more than 14,000 electric buses for STUs in nine large cities, and a smaller e-truck incentive pool. The L5 electric three-wheeler component, however, was closed on December 26, 2025 after its allocation was exhausted — a reminder that the scheme is fund-limited and components shut when the money runs out. Our PM E-DRIVE explainer tracks the component-wise status.
What Fleet Buyers Should Do Now
- E-bus and e-truck tenders: Ask OEMs in writing whether the offered vehicle's traction motor is PMP-compliant and subsidy-eligible under the September 1 rule. Build a price adjustment clause into contracts in case the ministry grants a retrospective extension.
- Last-mile fleets: Three-wheeler and small-van (N1) purchases are unaffected. Delhi's EV Policy 2026 adds up to Rs 1 lakh purchase incentive plus Rs 50,000 scrappage benefit for N1 electric goods vehicles registered in the capital.
- Depot charging: With 73% of public chargers below 30 kW, fleet economics depend on owned depot chargers. PM E-DRIVE's Rs 2,000 crore charging allocation remains available through 2028.
Frequently Asked Questions
What is the September 1, 2026 EV localisation rule?
Under PM E-DRIVE's Phased Manufacturing Programme, traction motors for electric buses (M2/M3) and electric trucks (N2/N3) must be assembled in India — including magnet, rotor, stator, shaft, bearing, enclosure, connector and cable fitment — for the vehicle to qualify for subsidies. Imported complete motors were permitted until August 31, 2026.
Did the government extend the traction motor localisation deadline?
Not as of September 1, 2026. SIAM requested on July 22 that the deadline move to April 1, 2027, but no extension was announced. The deadline had already been deferred twice, in September 2025 and March 2026.
Does the rule ban imported electric buses or trucks?
No. It only affects eligibility for PM E-DRIVE incentives. Vehicles with imported motors can still be sold and registered, but without the subsidy.
How are electric three-wheelers performing in 2026?
Very strongly. Electric three-wheeler sales reached a record 8,30,819 units in FY2026, up 19%, with Mahindra Last Mile Mobility (1,01,905 units) and Bajaj Auto (89,604 units) leading. Mahindra's three-wheeler sales rose 42% year-on-year in August 2026, and three-wheeler EV penetration is above 60%.
