In a strategic move to future-proof its mobility offerings, Tata Motors has partnered with Chinese automotive electronics leader Desay SV Automotive to co-develop the core architecture and software stack for its next generation of software-defined vehicles (SDVs).
According to sources familiar with the development, the collaboration focuses on building a centralised compute architecture and domain controller-based electronics systems. These are seen as critical enablers for advanced driver assistance systems (ADAS), over-the-air (OTA) updates, vehicle-to-cloud integration, and personalised in-cabin experiences — hallmarks of modern connected vehicles.
Tata Motors has already assembled a team of more than 100 engineers at its Pune facility to work on the SDV programme. This initiative supports the development of the company’s upcoming TiDAL SDV platform, a modular, software-oriented architecture designed to decouple hardware from software. The TiDAL platform promises faster feature rollouts, improved cybersecurity, seamless OTA updates, and the ability to upgrade digital features without redesigning the vehicle.
Desay SV Automotive, a key supplier to global players like Volkswagen, NIO, and BYD, brings expertise in cockpit domain controllers, high-performance computing platforms, and integrated software stacks — all essential as automakers shift toward a software-first approach.
This partnership comes at a time when Tata Motors is gearing up for an extensive product overhaul, planning 30 new models over the next five years, including seven all-new nameplates. The move to SDV platforms is expected to strengthen its position as the automotive industry transitions to connected, electric, and autonomous mobility.
The alliance also marks an inflection point for India’s automotive sector, which is increasingly adopting software-defined architectures to meet rising consumer expectations around digital interfaces, safety, and upgradeable features — not just in premium vehicles, but even in mass-market segments.
Tata Motors is also expected to leverage the expertise of group companies such as Tata Elxsi, Tata Consultancy Services, and Tata Technologies to support the initiative, particularly in embedded software, system integration, and validation.
While Tata Motors did not officially comment on the specifics of the partnership, sources indicated that the collaboration will power upcoming electric and internal combustion engine vehicles for both Indian and global markets, including the anticipated Avinya series, slated to debut in 2027 with advanced electronics and immersive digital features.
By aligning with Desay SV, Tata Motors signals its intent to compete in the fast-evolving landscape of automotive intelligence, where vehicles are increasingly defined by their computing power, connectivity, and upgradable software layers as much as — if not more than — their mechanical performance.
