<p>The Indian auto component sector is organized around a multi-tier supply chain, with Tier-1 manufacturers directly supplying major OEMs such as Maruti Suzuki, Mahindra & Mahindra, Hyundai Motors, and Tata Motors. The transmission and drivetrain vertical spans gearboxes, differential gears, shafts, clutches, and increasingly, electric axle assemblies integrating motors, inverters, and reduction gears. India's OEM segment, valued at US$ 58.20 billion in 2024, commands approximately 60% of the total domestic auto component market demand, reflecting the sector's concentrated customer base.</p><p>Geographically, manufacturing is heavily clustered: Maharashtra, Tamil Nadu, and Haryana together account for nearly 68% of India's total Gross Value Added (GVA) from the manufacture of motor vehicle parts and accessories as of FY2023-24.

Gujarat's Sanand cluster is rapidly emerging as a hub for passenger vehicle OEMs and advanced powertrain components, while Tamil Nadu hosts major investments such as Allison Transmission's Chennai facility expansion, with initial production slated for Q1 2026 and full capacity ramp-up targeted for 2027. TACO Punch Powertrain, a Tata AutoComp Systems venture, operates a 2,510 square meter dual clutch transmission assembly facility in India with an annual production capacity of approximately 200,000 units that is expandable. Hyundai Transys also maintains an internal combustion engine powertrain production plan in India, and Craftsman Automation Ltd has invested INR 150 crore in a new Hosur manufacturing plant for automotive and industrial components.</p><p>The sector's employment footprint is substantial: approximately 65% of workers in OEM and Tier-1 automotive plants face moderate impacts due to the manufacturing shift from internal combustion engine vehicles (ICEVs) to battery electric vehicles (BEVs), as production requirements for transmission and braking systems evolve.

Concurrently, a shortage of skilled technicians remains a constraint on capacity expansion plans across the industry.</p>

Project-specific demand drivers

• Auto PLI scheme
• EV transition acceleration
• Localisation of imported components
• Two-wheeler electrification
• Commercial vehicle BS-VII compliance
• Aftermarket organised play growth

<p>Technology in the OEM transmission sector is undergoing a fundamental transformation driven by global electrification and tightening CO2 regulations. The integration of electric motors, inverters, and reduction gears into compact e-axles is emerging as a defining trend, with examples including BYD's 8-in-1 integrated unit and Hyundai's P1+P2 hybrid powertrain layouts. Hybrid and battery electric vehicle e-axle adoption is contributing over 1.5% to market CAGR forecasts, and the modular manufacturing systems now being deployed allow OEM transmission plants to simultaneously run ICE transmissions and EV gearboxes on common hardware and software architectures, offering production flexibility during the energy transition.</p><p>On the environmental and efficiency front, the U.S.

Environmental Protection Agency has established specialized Energy Performance Indicator (EPI) scores on a 1-100 scale for motor vehicle transmission plants, where facilities achieving a score of 75 or higher qualify for ENERGY STAR plant certification. In 2022, Ford Motor Company collaborated through the Suppliers Partnership for the Advancement of Clean Technology, exemplifying how global OEMs are pushing energy efficiency standards through their supply chains. Automation trends are also reshaping manufacturing economics, with flexible production layouts enabling rapid switching between product variants.</p><p>From a materials science perspective, the global automotive metals market is valued at USD 411.4 billion in 2025 and USD 439.4 billion in 2026, with aluminum die casting representing a particularly fast-growing sub-segment for transmission housings and e-axle casings.

The U.S. automotive parts aluminum die casting market alone is valued at USD 5.96 billion in 2025, growing to USD 6.42 billion in 2026, with aluminum remaining a primary material segment alongside steel and specialty alloys for transmission components. The shift toward lighter materials is accelerating as EV powertrain architecture demands optimized thermal and structural properties in gearbox housings.</p>

The project’s ₹25.3 crore to ₹332 crore CapEx band supports multiple financing structures. For the ₹25.3-50 crore range (SME Tier-2 supplier), KAMRIT recommends a 75:25 debt-to-equity structure anchored on SIDBI’s ₹10 crore Soft Loan Scheme for Technology Upgradation (interest rate: SBI PLR minus 2%, tenure 10 years with 2-year moratorium) combined with CGTMSE-backed collateral-free working capital.

For the ₹50-150 crore mid-tier project, SBI and HDFC Bank offer TL rates of 9.5-10.5% (floating, MCLR-plus) with Auto PLI disbursement as additional security cover. SIDBI’s ₹50 crore limit under its Tech Financing Scheme and EXIM Bank’s Line of Credit for capital equipment import (10% processing fee, 7-year tenure) reduce effective borrowing cost.

The ₹150-332 crore large-scale plant qualifies for Auto PLI incentives (15% increment on approved sales, capped at ₹3,000 crore over 5 years), NABARD’s ₹75 crore refinance limit for MSME expansion, and state-level incentives (Gujarat’s EV Policy 2024: 10% capital subsidy on CapEx up to ₹50 crore; Tamil Nadu’s EV Policy: 20% electricity duty exemption for 5 years).

Working capital cycle for OEM supply (T+60 payment terms): raw material inventory 30-45 days, WIP 15-20 days, finished goods 7-10 days, receivables 60-75 days. Total WC requirement: ₹8-12 crore for ₹50 crore revenue scale. Recommended WC facility: ₹10 crore CC limit at 9-9.5% from consortium bank.

Debt service coverage ratio (DSCR): 1.6x minimum at stabilisation (Year 3). IREDA refinance available for energy-efficient furnace equipment (IOT-based furnace, waste heat recovery) at 50 bps below market rate.

<p>The transition from ICEV to BEV powertrains poses an existential structural risk to traditional multi-speed transmission manufacturing. Approximately 65% of workers in OEM and Tier-1 automotive plants face moderate disruption as ICE transmission and braking system production requirements evolve, while the primary technology substitutes for traditional transmissions include battery electric vehicle single-speed gearboxes, e-axle modules, and direct-drive architectures that use fewer moving parts and simpler transmission designs. This shift could render significant portions of existing transmission plant capacity and workforce skills obsolete within the forecast horizon.</p><p>Geopolitical and trade policy volatility presents acute near-term risk.

The implementation of 2026 trade policies, including heightened U.S. automotive tariffs on South Korea and shifting regional trade measures, creates severe cost and cross-border shipping unpredictability for OEM transmission plants with global supply chains. Raw material costs remain a pressure point: the global automotive metals market expanded from USD 411.4 billion in 2025 to USD 439.4 billion in 2026, and steel, aluminum, and specialty alloy price volatility can materially compress the 4.7% average EBIT margins typical of global automotive suppliers, with Indian manufacturers facing similar margin constraints.</p><p>Regulatory compliance costs are set to rise. The mandatory BIS certification under the Machinery and Electrical Equipment Safety (Omnibus Technical Regulation) Order, 2024, takes effect on September 1, 2026, requiring transmission component manufacturers to upgrade quality systems and testing infrastructure.

Supplier financial distress among European and global automotive component manufacturers, some of whom are key technology licensors or sub-suppliers for Indian OEM transmission plants, could disrupt supply continuity. Additionally, the BIS mandatory compliance deadline requires companies to ensure energy performance and safety standards across all transmission equipment, with non-compliance risking market exclusion.</p>
