08.6 · Autos & ancillaries¶
Sector playbook. Autos are the most measurable sector in India — monthly wholesale (SIAM), retail (FADA) and registration (VAHAN) data by segment, maker and state — and the one where the demand cycle, the EV transition and commodity costs interact most visibly. FY26 was a record year (28 million units, +7%; tractors +19%; EV registrations 3.5 million). This page covers OEMs by segment, the component supply chain and what to watch as the cycle matures.

1. How the industry makes money¶
| Segment | Economics | EBITDA margin | Cycle driver | Leaders (verify) |
|---|---|---|---|---|
| Two-wheelers | Volume game; 20+ million units; exports 15–25% of volumes; financing penetration rising | 12–20% (Bajaj, TVS, Hero, Eicher/Royal Enfield 25%+) | Rural incomes, financing, fuel prices; EV penetration (6.5% of 2W in FY26 — BusinessToday) | Hero MotoCorp, Bajaj Auto, TVS, Eicher (case I6), Ola Electric, Ather |
| Passenger vehicles | 4.7 million units FY26; SUV mix > 55%; premiumisation | 10–15% | Urban incomes, interest rates, model launches; EV 4.3% share | Maruti Suzuki, Tata Motors PV, M&M, Hyundai India |
| Commercial vehicles | Most cyclical: freight demand, infra capex, replacement; 1 million+ units FY26 | 8–14% | GDP/IIP, fleet-operator economics, financing (Nirmal Finance's customers), scrappage policy | Tata Motors CV, Ashok Leyland, Eicher (VECV) |
| Tractors | Rural/monsoon-linked; 1 million+ units FY26 (+19%) | 15–20% | Monsoon, crop prices, rural credit, government support | M&M, Escorts Kubota, Sonalika (unlisted) |
| Three-wheelers & small CVs | EV penetration highest (e-rickshaws) | Last-mile logistics | Bajaj, Piaggio, Mahindra | |
| Components | Tier-1/2 suppliers; content per vehicle; OEM programmes; exports and aftermarket | 10–18% (commodity parts lower; technology/proprietary higher) | OEM volumes; content per vehicle (EV, safety, emissions); exports; commodity pass-through with 1–2 quarter lag | Bosch, Motherson, Bharat Forge, Sona BLW, Uno Minda, Endurance, Schaeffler, Sundram Fasteners, Exide/Amara Raja (batteries) |
| Auto software / ER&D | Engineering services to global OEMs | 15–20% | Software-defined vehicles | KPIT, Tata Elxsi, Tata Technologies (08.2) |
2. Value chain and structure¶

OEMs hold the power over Tier-1s (annual price-downs, pass-through clauses) except where the supplier has proprietary technology.
3. KPIs¶
| KPI | Where | Notes |
|---|---|---|
| Volumes by segment, model, geography; wholesale (SIAM) vs retail (FADA) vs registrations (VAHAN) | Monthly; company releases | Wholesale > retail for months = dealer inventory build (a classic pre-downturn signal); FADA publishes dealer inventory days |
| Market share | SIAM/FADA/VAHAN | By segment and by fuel (EV vs ICE) |
| Realisation per vehicle | Revenue ÷ volumes | Mix (SUVs, premium 2W), price increases |
| EBITDA per vehicle | The unit-economics metric; compare across OEMs | |
| Gross margin vs commodity basket | Steel, aluminium, precious metals (catalysts), rubber | 1–2 quarter lag; OEM pass-through to consumers via price hikes |
| Capacity utilisation; capex; new plants | Capital cycle: PV capacity additions announced in 2024–26 | |
| Order book / waiting periods (PVs) | Concalls | A demand signal that reverses sharply |
| Dealer inventory days | FADA | > 30 days (2W) / > 40 days (PV) is a warning |
| Financing penetration; NPA trends at auto NBFCs | Lenders' disclosures | Demand's credit engine |
| Content per vehicle (components) | Presentations | The EV/premiumisation lever |
| Export volumes and geographies | Africa/LatAm for 2W; Europe for components | |
| EV metrics | Penetration by segment; battery cost; subsidy (PM E-DRIVE) status; charging | Policy-sensitive |
4. What drives earnings and multiples¶
- The demand cycle: PVs and CVs track incomes, rates and infrastructure; 2W and tractors track rural incomes and the monsoon. FY26 was a peak year across segments (record retail 2.97 crore units, +13% — FADA); the base effect makes FY27 growth harder, and August 2026 retail (+18%) suggests the cycle is still running (Business Standard).
- Commodities: steel/aluminium/precious metals swing gross margins by 200–400 bps; OEMs pass through with lags and lose volume when they raise prices into weak demand.
- Regulation: emission norms (BS-VI, CAFE), safety mandates, GST (the September 2025 GST cut on small cars and two-wheelers — verify — was a demand catalyst), scrappage policy, EV subsidies and localisation rules.
- EV transition: 2W and 3W first; PVs slower; CVs slowest. It changes the component pie (engines, exhausts and transmissions lose; batteries, motors, electronics gain), the competitive set (new entrants), and margins during the transition. Model content-per-vehicle by powertrain for component companies.
- Multiples: OEMs 15–30x P/E through the cycle (Maruti/M&M at the top on growth and mix; Tata Motors on SOTP post-demerger — case I15); premium 2W (Eicher) 25–35x; components 20–40x for technology leaders, 10–20x for commodity parts. Use normalised margins for CVs and mid-cycle volumes for OEMs (07.3).
5. Accounting quirks¶
Finance subsidiaries consolidated into OEMs (Tata Motors Finance, M&M Finance associate) — separate the industrial and finance businesses for leverage and valuation; development costs capitalised (Ind AS 38 — Tata Motors/JLR capitalises heavily; Maruti expenses); warranty and recall provisions; export incentives; PLI for auto components; JLR consolidation and currency (GBP, USD, EUR); dealer incentives netted from revenue; inventory of finished vehicles at quarter-end.
6. Red flags¶
Wholesale far above retail for consecutive months; dealer inventory > 45 days; discounts rising while "demand is strong"; capitalised development costs rising faster than R&D disclosure; finance-subsidiary NPAs rising while OEM volumes grow (financed demand); a component supplier's top customer losing share; EV start-ups' unit economics (subsidy-dependent gross margins, warranty costs, cash burn — the 2024–26 experience of listed EV 2W makers); promoter-group related-party transactions in dealerships or components.
7. How to value¶
OEMs: mid-cycle EBITDA per vehicle × normalised volumes → EV/EBITDA and P/E with the cycle stated; SOTP for groups with finance arms, JLR or listed subsidiaries. Components: P/E vs growth with content-per-vehicle and customer-mix drivers, EV-transition scenarios. EV start-ups: 07.4. Always cross-check with VAHAN data for the last three months before believing a volume forecast.

9. The 10-question sector checklist¶
- Where in the cycle are volumes (vs 5-year average and vs last peak), by segment?
- Wholesale vs retail vs registrations — is the channel filling?
- Realisation and EBITDA per vehicle trend; commodity pass-through lag?
- Regulatory calendar: emissions, safety, GST, subsidies, scrappage?
- EV: penetration in the segment, the company's position, and content-per-vehicle exposure (components)?
- Capacity and capex vs demand — is the industry adding too much?
- Financing: penetration and lender asset quality in the segment?
- Exports: share, geographies, currency, tariffs?
- Group structure: finance arm, overseas subsidiaries, listed subsidiaries, related parties?
- What volumes and margins does the multiple imply, and are they mid-cycle or peak?
