SPR Auto Technologies, formerly known as Shriram Pistons & Rings, is transforming from a piston specialist into a comprehensive automotive supplier, leveraging acquisitions to diversify into EV motors, cabin systems, and interior components, aiming to better serve OEMs in India’s evolving market.
SPR Auto Technologies is trying to reinvent itself from a specialist in engine parts into a broader automotive supplier that can serve vehicle makers across combustion, electric and interior platforms. The company, best known for pistons, piston rings and engine valves, has used a string of acquisitions to move into high-precision injection-moulded parts, EV motors and controllers and cabin systems, according to its own corporate material and company filings.
That shift has been deliberate. Screener and the company’s website say SPR Auto Technologies, formerly Shriram Pistons & Rings, has built out an end-to-end product mix aimed at original equipment manufacturers, or OEMs, rather than relying only on traditional powertrain parts. The company says this approach is meant to improve both performance and cost competitiveness for customers.
The most visible change came through acquisitions, including control of Takahata Precision India and TGPEL Precision Engineering, a larger stake in SPR EMF Innovations, the Singapore-based EV motor and controller business, and the purchase of Karna Intertech for mould-making. In January 2026, SPR also bought three Grupo Antolin businesses in India, adding automotive interiors and lighting products such as headliners, door panels and centre consoles under a technology licence arrangement.
This expansion is already changing the company’s revenue profile. Trade Brains says powertrain-agnostic products now account for more than 35% of consolidated revenue, reducing dependence on internal combustion engines at a time when the pace of India’s EV transition remains uncertain. The company’s own quarterly presentation, as cited by Trade Brains, showed consolidated income rising 51% year on year in the June quarter, even as margins eased under commodity and supply-chain pressure.
The integration challenge is now as important as the growth story. Trade Brains said standalone profit was weighed down by finance costs tied to Rs 1,000 crore of non-convertible debentures used to fund the Antolin deal, while debt levels increased. Still, the broader opportunity is clear: the automotive interiors market in India is expected to expand steadily over the next five years, and SPR already counts several major OEMs among its customers across both legacy and acquired businesses.
