Industry-wide ₹8,000-15,000 Cr cumulative penalty exposure FY28-FY32 modelled OEM by OEM, plus the capex required to close the gap and the PLI / FAME / GST incentive stack that offsets it.
If OEMs take no action and the BEE notification activates as drafted — 3.0× BEV super-credit flat, no pooling, strict enforcement — the per-OEM penalty exposure looks as follows. The third column is the gross penalty if the deficit is fully unmet; the fourth is the ‘likely actual cost' factoring in BEV ramp, SHEV mitigation, and partial credit purchases at clearing prices.
| OEM | 5-yr deficit potential | 5-yr penalty if no action | Likely actual cost |
|---|---|---|---|
| Maruti Suzuki | 1.5-3 g/km × 1.8M+ units | ₹2,000-5,000 Cr cumulative | ~₹1,500 Cr (SHEV mitigates) |
| Hyundai Motor India | 2-13 g/km × 650K+ | ₹2,000-4,500 Cr | ~₹2,800 Cr |
| Kia India | 5-15 g/km × 300K+ | ₹800-1,800 Cr | ~₹1,200 Cr |
| Mahindra & Mahindra | 0-9 g/km × 500K+ | ₹0-1,500 Cr | ~₹500 Cr (BEV ramps) |
| Honda Cars India | 13-21 g/km × 100K | ₹600-1,200 Cr | ~₹600 Cr (penalty-leaning) |
| Skoda-VW India | 20-25 g/km × 100K+ | ₹1,200-2,500 Cr | ~₹800 Cr (pooling lobby) |
| Mercedes-Benz | 14-22 g/km × 25K | ₹350-700 Cr | ~₹400 Cr |
| BMW India | 9-15 g/km × 18K | ₹150-350 Cr | ~₹200 Cr |
| Audi India | 9-20 g/km × 9K | ₹100-250 Cr | ~₹150 Cr |
| Renault-Nissan | 11-16 g/km × 75K | ₹200-500 Cr | ~₹300 Cr |
The aggregate
₹8,000-15,000 Cr cumulative penalty exposure FY28-FY32 across the deficit-side OEMs if no action is taken and no super-credit haircut occurs. Likely actual cost falls in the ₹7,000-10,000 Cr range as OEMs partially close the gap through BEV ramp, SHEV deployment, off-cycle tech, and OTC credit purchases.

Run it in TerraNova →Under base-case assumptions (3.0× super-credit holds, BEV ramps deliver as guided), four OEMs generate meaningful surplus over the FY28-FY32 block. Tata is in a league of its own on absolute volume.
| OEM | 5-yr surplus generated (g-units) | OTC value @ ₹2,500/g.u floor | Banked carry-forward share |
|---|---|---|---|
| Tata Motors | ~60M | ₹15,000 Cr | ~80% banked (oversupply) |
| MG Motor (JSW-MG) | ~9M | ₹2,250 Cr | ~₹1,800 Cr realised |
| BYD India | ~7M | ₹1,750 Cr | ~₹1,400 Cr realised |
| Toyota Kirloskar | ~5M | ₹1,250 Cr | Mostly tradable |
| Volvo Cars India | ~500K | ₹125 Cr | Tradable |
The structural problem
Tata's nominal ₹15K Cr surplus is real on paper but ~80% of it is banked in the base case because supply outstrips demand by ~7×. That is roughly ₹12,000 Cr of ‘scrip nobody wants’ — the structural fragility in the oversupply scenario. Tata's lobbying position is in part designed to prevent exactly this outcome.
The Excel CAFE-III market model produces four scenario outputs that bracket the realistic range. Headline market values vary by an order of magnitude depending on super-credit policy and BEV-ramp assumptions.
| Scenario | 5-yr OTC market value | S/D ratio | Clearing price |
|---|---|---|---|
| Base case (3.0× flat, base BEV ramps) | ₹12,360 Cr | 7.03 (heavy supply) | Floor ₹2,500/g.u |
| EU phase-out (3.0→2.0→1.0 schedule) | ₹31,730 Cr | 0.85 (balanced) | Mid-range moving to ceiling |
| Downside (BEV −25%, no pooling, strict enforcement) | ~₹15,000 Cr OTC + ~₹40,000 Cr penalty | <0.5 (undersupplied) | Ceiling ₹4,500/g.u |
| Upside (BEV +25%, pooling on, lax enforcement) | ~₹4,000 Cr | >10 (extreme oversupply) | Floor |
The downside scenario produces the largest aggregate market because penalty value dominates — OEMs that cannot meet target and cannot buy enough credits pay the EC Act Section 26 penalty directly. The upside scenario produces the smallest market because pooling allows internal netting and lax enforcement removes the demand floor.
Closing the CAFE-III gap is not free. The capex needed across product platforms, BEV launches, battery sourcing, manufacturing line retooling, and dealer infrastructure is meaningful for every major OEM.
| OEM | Estimated capex commit FY26-FY30 | Key drivers |
|---|---|---|
| Tata Motors | ₹3,500-5,000 Cr | Sierra EV, Avinya 1, Curvv EV ramp, Harrier EV, Tata Power TPEZ charging network |
| Maruti Suzuki | ₹5,000-7,000 Cr | eVitara, eWagonR, eSwift, SHEV powertrain investments across volume models |
| Mahindra | ₹3,000-4,000 Cr | INGLO BEV platform (BE 6, XEV 9e, Sierra EV) |
| Hyundai Motor India | ₹2,500-3,500 Cr | Creta EV, Carens EV, Inster localisation, charging partnerships |
| Toyota Kirloskar | ₹1,500-2,500 Cr | SHEV powertrain expansion, bZ4X local assembly evaluation |
| Honda Cars India | ₹500-800 Cr | e:HEV powertrain refresh; BEV from FY29 contingent on import economics |
The real cost question
CAFE-III capex is mostly capex the OEMs would do anyway under their existing strategy plans — what CAFE-III does is harden the timeline and shift the spend forward. The marginal CAFE-driven capex is closer to 20-40% of the headline numbers above.
BEV economics in India are propped up by a deep stack of incentives that offset the capex and per-unit cost gap to ICE. The stack is what makes the per-unit value of a BEV actually defensible at sub-₹20L price points.
Consider a single Tata Nexon EV at a notional ₹14L pre-tax ex-factory base. The total incentive + CAFE value stack adds up as follows.
| Component | Per-unit value | Mechanism |
|---|---|---|
| 5% GST vs 28%+cess advantage | ~₹2,40,000 | Permanent (subject to GST Council review) |
| State road-tax waiver / registration | ~₹85,000 | Average across major EV-policy states |
| PLI-Auto pass-through | ~₹65,000 | 18-20% on incremental AAT sales, manufacturer-level |
| CAFE super-credit value | ~₹2,10,000 | At BEE OTC ceiling pricing, fully realised |
| Total stack per Nexon EV | ~₹5,60,000 | ~40% of the pre-tax base price |
The strategic implication
Of the ~₹5.6L stack, ~₹2.1L is CAFE super-credit value. If BEE haircuts the multiplier mid-block, this drops to ~₹1L or lower. The decision Tata makes today on how aggressively to ramp the Sierra EV and Avinya 1 is pricing in the full ₹2.1L — if the multiplier moves, the BEV-economics calculus shifts materially.
TerraNova for Treasury Teams
TerraNova surfaces the per-unit value stack across your full lineup, with each component as a switchable lever.
Book a treasury walkthrough →The market for CAFE-III tooling and advisory is bounded by the number of obligated OEMs (22 PV makers across mainstream and premium) and the scale of decisions they need to support. Climate Decode's estimated addressable revenue across the FY28-FY32 block:
Conservative 5-year cumulative: ₹500-1,500 Cr addressable across the full stack. The platform layer is the anchor; advisory and methodology are higher-margin add-ons; the index and government work compound brand position over time.
