# Sona Comstar ties up with Denso to build India’s EV motor stack 2026-08-24T03:31:42+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet Sona Comstar is developing a complete indigenous electric vehicle drivetrain through its Bharat Motor project in partnership with Japan's Denso. MD & Group CEO Vivek Vikram Singh said the company aims to build motors and inverters designed specifically for Indian road conditions while localising the supply chain. The collaboration, the company said, will create an engineering powerhouse producing high-value components for both domestic and global markets. Sona Comstar, already a major supplier of differential gears and starter motors to automakers including Maruti Suzuki and Bajaj Auto, is betting on the partnership to crack the EV motor and controller segment that currently relies heavily on Chinese imports. ## Indian Opinion Analysis Electric vehicle adoption in India remains below 7% of total vehicle sales, held back partly by the absence of a homegrown motor-and-controller supply chain that can deliver at scale and cost. The Bharat Motor project directly targets that gap. Sona Comstar's tie-up with Denso, a Toyota group company, gives it access to decades of motor-control intellectual property that most Indian EV entrants lack. The real test will be whether the partnership can produce a complete drivetrain package, motor, inverter, and software, that undercuts imported Chinese systems by enough margin to win contracts from Maruti Suzuki, Tata Motors, and the two-wheelers that drive 60% of India's EV registrations. First production samples are expected in 2026. ## Coverage - auto.economictimes.indiatimes.com Leads with a corporate ambition story, no government actors mentioned, purely business development reporting This story was synthesised by AI from the source linked above.
