Synopsis: Sona Comstar has hit record production milestones of 500 million differential gears and 10 million assemblies,reflecting a nearly doubled global market share of 8.7%.

Sona BLW Precision Forgings Ltd. officially achieved two major manufacturing milestones on April 7, 2026: production of 500 million differential gears and 10 million differential assemblies since 1995. 

This announcement highlights a significant increase in production speed; while it took 14 years to produce the first 100 million gears, the most recent 100 million were made in less than two years. 

This rapid growth mainly comes from the company’s increasing involvement in the global Battery Electric Vehicle (BEV) segment. Sona Comstar’s global market share in differential gears has jumped from 4.5% in 2019 to an estimated 8.7% in 2025. 

Management noted that the next 5 million assemblies were completed in under three years, showing the trust global OEMs have in their facilities in Gurugram, Pune, and Manesar.

Sona BLW Precision Forgings Limited was trading at ₹512.25 on April 7, 2026 on NSE, up 0.56% with a market capitalization of ₹31,854 crore.

Despite an intraday dip to ₹499.20, the stock recovered to a high of ₹514.80, supported by the milestone announcement. Over the past year, the stock has delivered an annual 34.87% return, significantly outperforming the Nifty Auto index’s 22% gain.

Sona BLW Precision Forgings Limited is an Indian multinational automotive systems and components manufacturer. It specializes in precision forged gears, differential assemblies, and starter motors for conventional and electric vehicles.

Crossing the 500 million mark is not just a volume milestone; it confirms Sona Comstar’s technological advantages during the EV transition. As driveline requirements become stricter for high-torque electric motors, the company’s six-year market share growth shows its readiness to lead the global supply chain. For FY 2026-27, the focus will be on maintaining these margins as global BEV adoption continues to change the automotive landscape.
