Sona Comstar Bets on 10x Growth Amid Joint Ventures
Sona Comstar is a company that makes parts for cars and trucks.
In July 2026, it sold a part of its business that builds electric‑vehicle drivetrains to a new company it owns, and gave a big Japanese company called Denso a 49% share.
The next day, Sona announced a new robotics division that already has orders worth 600 crore rupees.
The company has grown from one product to five different kinds of parts, including motors, sensors, railway equipment, and robotics.
Even though a rare‑earth magnet shortage hurt its sales in 2026, Sona made new motors that don’t need those magnets and still grew a lot.
In the first quarter of 2027, it earned 1,310 crore rupees, with 436 crore coming from electric‑vehicle parts.
Sona’s plan is to keep growing by working with partners like Denso and by using its existing skills in new areas like robotics.
Sona BLW Precision Forgings sold its 2W/3W EV drivetrain unit to a subsidiary for Rs 893 crore and gave 49% of that subsidiary to Denso at an enterprise value of Rs 1,750 crore.
The company launched “Sona Comstar 2.0” with a robotics vertical that already secured Rs 600 crore in orders, reporting 54% revenue growth and double‑digit EV revenue increase in Q1 FY27.
Sona’s business now spans five verticals—driveline, motors, sensors, railway equipment, and robotics—supported by acquisitions in Serbia, China, and India.
Joint ventures with Denso provide high‑voltage EV technology to Sona and low‑voltage drivetrain to Denso, while Sona retains majority control of the low‑voltage JV.
Despite a rare‑earth magnet supply crisis in FY26, Sona developed rare‑earth‑free motors and achieved record FY26 revenue of Rs 4,475 crore, with Q1 FY27 revenue at Rs 1,310 crore and BEV revenue at Rs 436 crore.
