Every fourth car part shipped out of an Indian factory these days is headed somewhere else entirely — Germany, the US, Thailand, Italy. India’s auto component industry now exports roughly 28 percent of what it makes, and the sector as a whole crossed $80 billion in turnover for FY2025, growing at a steady 14 percent CAGR. What’s driving it isn’t just cheap labour anymore — Indian factories now run IATF 16949 and ISO 14001 certifications as standard, and manufacturing costs still sit 10-25 percent below Europe and Latin America even at that quality bar. That combination has made India the default sourcing destination for a widening list of global automakers. Here are the ten companies actually building the parts.
1. Samvardhana Motherson International
Motherson is, by a wide margin, India’s biggest component maker by market capitalisation, and the numbers back up that scale — operating revenue hit roughly ₹987 billion in FY2024, up from ₹788 billion the year before. Founded in Noida in 1975, the company has grown from a domestic wiring harness supplier into a genuinely global operation spanning over 41 countries, supplying wiring harnesses, plastic parts, rearview mirrors, and interior modules.
What makes Motherson stand apart is its client list — it’s the go-to supplier for luxury European marques including Audi, BMW, and Mercedes-Benz, alongside domestic giants like Maruti Suzuki and Tata Motors, a customer spread that few other Indian suppliers have managed to build.
2. Bosch Limited
Bosch holds the title of India’s largest auto parts manufacturer by both revenue and market capitalisation, a position built on technology depth rather than sheer manufacturing volume. Established in India in 1951 and headquartered in Bengaluru, the company runs its largest development centre outside Germany right here, focused on fuel injection systems, braking systems, sensor technology, and increasingly ADAS components as vehicles move toward software-defined architectures.
Bosch’s position in India goes beyond parts supply — it’s actively spearheading the shift toward hydrogen fuel cell technology and software-defined vehicles in the domestic market, positioning itself less as a component vendor and more as a technology partner shaping where Indian automakers head next.
3. Bharat Forge
Few companies anywhere can claim what Bharat Forge operates in Pune — the world’s largest single-location forging facility, a scale advantage that’s hard to replicate. Founded in 1961, the company posted consolidated revenue of roughly ₹15,123 crore in FY2024-25, manufacturing safety-critical forged and machined components including crankshafts, front-axle assemblies, connecting rods, and transmission parts.
Unlike suppliers locked into passenger vehicle demand cycles, Bharat Forge has deliberately diversified into defence, aerospace, railways, marine, and energy sectors, a hedge that’s cushioned it against the automotive industry’s periodic slowdowns in a way narrower competitors can’t match.
4. Uno Minda
Uno Minda has ridden a genuine surge in net worth on the back of aggressive EV component expansion, particularly on-board chargers and motor controllers for two-wheelers — a segment where India’s electrification is happening fastest. Its traditional strengths in switching systems, acoustics, and alloy wheels remain the revenue backbone, but the EV pivot is where the growth story now sits.
That timing has worked in Uno Minda’s favour — two-wheeler electrification in India has outpaced four-wheeler EV adoption considerably, and a supplier already positioned in switches and controls for that segment had a natural runway into the electric components those same vehicles now need.
5. Sona BLW Precision Forgings (Sona Comstar)
Sona Comstar has positioned itself as something genuinely rare among Indian component makers — a pioneer specifically in EV component manufacturing rather than a conventional supplier bolting on electric parts as an afterthought. Its differential gears, starter motors, and Belt Starter Generator systems serve both ICE and EV platforms, giving it relevance regardless of which powertrain wins out in any given vehicle segment.
That dual-relevance strategy — components that matter whether a car runs on petrol or electrons — has made Sona Comstar one of the more resilient bets in a sector otherwise nervous about which side of the EV transition to commit capital toward.
6. Tata AutoComp Systems
Tata AutoComp, established in 1995, has built its identity around interior and exterior vehicle systems alongside thermal and powertrain components, serving as one of the more diversified suppliers within the broader Tata Group ecosystem. Being part of that larger conglomerate gives it a built-in anchor customer in Tata Motors while it competes for external OEM business elsewhere.
That internal-plus-external customer base is a structural advantage few standalone component makers enjoy — guaranteed baseline demand from Tata Motors’ production lines, cushioning the company while it builds credibility with other automakers.
7. Endurance Technologies
Endurance has moved decisively into safety systems, announcing ₹135.6 crore in capital investment specifically for expanding Anti-lock Braking System production ahead of new regulations making ABS mandatory for all two-wheelers above 50cc from January 2026. That regulatory tailwind has turned what was a compliance requirement into a genuine growth opportunity for suppliers positioned early.
The company’s bet on ABS capacity expansion reflects a broader pattern across Indian component makers — reading upcoming safety regulation not as a cost burden to absorb but as demand to capture before competitors catch up.
8. Lumax Industries
Lumax, part of the DK Jain Group, has built a genuine specialty in automotive lighting and plastic components, posting brand revenue around ₹10,000 crore in FY2025. Its headlamps, tail lamps, and lamp assemblies reach nearly every major OEM operating in India, alongside a growing focus on sustainable lighting solutions as automakers push toward more energy-efficient vehicle systems.
Lighting might sound like a narrow category compared to the powertrain and chassis suppliers on this list, but it’s become an increasingly technology-intensive segment as LED and adaptive lighting systems replace older, simpler designs — giving Lumax more room to differentiate on engineering than a purely commodity lighting supplier would have.
9. Rane Holdings
Rane serves nearly every vehicle segment India produces — passenger cars, commercial vehicles, two-wheelers, three-wheelers, and farm tractors — through a genuinely broad product range spanning steering gear products, suspension and steering linkage systems, die casting products, and engine valves. That breadth across vehicle categories gives Rane exposure most single-segment suppliers lack.
The company’s steering and suspension expertise has increasingly extended into electric power steering, a segment where it’s begun collaborating with global players like ZF, positioning itself for the more electronics-heavy steering systems that modern vehicles, EV or otherwise, increasingly demand.
10. Schaeffler India
Schaeffler operates as the Indian arm of the German precision-engineering giant, bringing bearing and precision component technology into the domestic auto supply chain. Reporting on a calendar-year basis rather than India’s typical fiscal year, the company’s presence reflects the broader trend of multinational component makers treating India as core manufacturing geography rather than a peripheral sourcing option.
That multinational parentage gives Schaeffler India access to global engineering standards and R&D that purely domestic suppliers have to build independently, a genuine edge in categories like precision bearings where manufacturing tolerance and material science expertise matter enormously.
Frequently Asked Questions
Q1. Which company is India’s largest auto component manufacturer by revenue?
A: Bosch Limited holds the position of India’s largest auto parts manufacturer by both revenue and market capitalisation, followed closely by Samvardhana Motherson International, which recorded operating revenue of roughly ₹987 billion in FY2024. Bharat Forge rounds out the top three by scale, distinguished particularly by operating the world’s largest single-location forging facility in Pune.
Q2. How is India’s shift toward electric vehicles affecting traditional auto component manufacturers?
A: EVs require fewer moving parts overall since they eliminate engines, exhaust systems, and traditional transmissions, which threatens demand for conventional ICE-focused components, but this shift simultaneously creates substantial new demand for EV-specific parts like wiring, sensors, and battery systems. Companies like Sona Comstar and Uno Minda have moved early into EV-relevant components such as differential gears, motor controllers, and on-board chargers specifically to capture this transition rather than being disrupted by it.
Q3. What government policies are supporting India’s auto component manufacturing growth?
A: The ₹26,058 crore Production Linked Incentive scheme for auto components and advanced automotive technology specifically encourages domestic manufacturing of EV batteries, drivetrains, and other advanced components, while the government’s broader Automotive Mission Plan targets US$300 billion in overall automobile industry turnover. Additional support includes easier credit access for MSME suppliers in the component supply chain, aimed at strengthening smaller manufacturers who form a significant part of India’s broader auto component ecosystem.
Q4. Which countries are the largest destinations for India’s auto component exports?
A: North America receives the largest share at roughly 34 percent of India’s auto component exports, followed by Europe at approximately 27 percent and Asia at 19 percent, with the United States alone accounting for about $3.5 billion or 28 percent of total exports. Companies like Samvardhana Motherson, Bosch, and Bharat Forge are among the largest exporters, shipping components specifically to the USA, Germany, Japan, and Mexico.
Q5. Why are global automakers increasingly sourcing components from India rather than other manufacturing hubs?
A: India offers a distinctive combination of cost-effectiveness, with manufacturing costs typically 10-25 percent lower than Europe and Latin America, alongside rigorous adherence to international quality certifications including ISO, IATF 16949, and CE standards. This balance of low cost and high quality compliance has positioned India as a preferred sourcing partner, particularly as global automakers look to diversify supply chains away from single-country dependence on China.
