Stellantis has built India into one of its key powertrain bases, with the group's Hosur plant in Tamil Nadu at the center of that effort, according to a report by HT Auto.

The Hosur facility, located in the Krishnagiri district of Tamil Nadu, has moved beyond serving only the domestic market and now functions as a manufacturing and engineering anchor for Stellantis powertrain operations across the group. HT Auto's plant-level report details how the site fits into the OEM's broader global footprint.

The report frames Hosur as evidence of a wider shift: global OEMs increasingly treat India not just as a vehicle market but as a production base for engines and drivetrain components that supply programs beyond the country's borders.

For Stellantis, the positioning matters. The group operates in India through its brands and has invested in local manufacturing capability as part of its strategy in one of the world's fastest-growing passenger vehicle markets. Hosur gives the group a powertrain manufacturing node in South Asia, complementing its assembly operations and component sourcing in the region.

HT Auto's account describes the plant's role within the group's supply chain and engineering organization, showing how output from Hosur supports Stellantis powertrain programs. The publication characterizes the site as a key base rather than a marginal assembly operation.

What to watch: Stellantis has not publicly tied the Hosur ramp-up to specific new capacity figures or launch dates in the material reviewed. Trade watchers should monitor the group's India announcements for confirmed production numbers, export volumes from Hosur, and any formal capacity expansion commitments — the metrics that would move this story from reported positioning to verifiable output.
