India’s SDV race heats up: local data, 5g, and cyber rules

By mid-2026, industry leaders like Mahindra's Dr. Shankar Venugopal and Prashanth Doreswamy highlighted a pivotal shift in automotive innovation, where software is poised to surpass hardware as the primary differentiator in vehicles. This evolution enables faster feature rollouts and sustained customer engagement beyond the showroom, underscoring the strategic imperative for OEMs to develop in-house core vehicle intelligence components—such as system architecture, software platforms, data strategies, control logic, cybersecurity, and customer experience—while outsourcing non-core elements like semiconductors and sensors. This approach not only sharpens competitive advantage but also aligns with the broader industry trend towards centralized and zonal computing architectures that streamline development cycles and reduce complexity and costs.

India’s uniquely complex driving environment—with its mixed traffic, unpredictable behavior, and poor lane discipline—poses significant challenges for Advanced Driver Assistance Systems (ADAS), making localized real-world data indispensable for effective software training and deployment. As CityQ Chairman Dr. Seshu B. emphasized, the core hurdle is not merely hardware or software but acquiring and leveraging India-specific ADAS data that captures this complexity. This necessity drives the demand for bespoke software architectures and data strategies tailored to Indian road conditions, ensuring that safety and performance standards are met in a landscape where generic global solutions fall short.

As software complexity escalates and continuous feature deployment becomes the norm, cybersecurity emerges as a defining challenge for automakers transitioning to software-defined vehicles. Managing risks across centralized compute platforms, OTA update systems, and V2X communications requires robust, layered security architectures that can differentiate safety-critical firmware updates from less sensitive software patches, ensuring integrity and rollback capabilities where it matters most.

South Korea has taken a pioneering role in shaping the global SDV landscape by establishing the first internationally binding technical standards under the ITU-T framework, clarifying core functional requirements and creating a unified vocabulary for OTA updates and connectivity. By chairing the committee responsible for ongoing SDV standardization, Seoul positions itself as a global leader influencing future regulatory and technical directions in this rapidly evolving domain.

In India, the collaboration between Tata Motors and cybersecurity firm HackersEra to secure AIS-189 certification for the Sierra.ev underscores how stringent national standards are accelerating SDV adoption by ensuring vehicles meet rigorous cybersecurity benchmarks. Tata Motors’ CTO Sven Patuschka highlighted that achieving AIS-189 readiness not only fortifies connected vehicle architectures but also expedites regulatory approvals and market entry, reinforcing the critical role of cybersecurity in delivering secure, future-ready mobility solutions.

The UK’s DRIVE35 programme, with its unprecedented £4 billion funding through 2035, exemplifies how strategic government investment is catalyzing the transition to software-defined vehicles (SDVs) by prioritizing software capabilities that enhance fleet operations. This financial backing not only accelerates R&D and scale-up efforts but also compels fleet operators to reconsider traditional procurement metrics, integrating software governance factors such as update frequency, remote diagnostics, and failure management into total cost of ownership assessments.

SDVs are revolutionizing fleet management by enabling predictive maintenance and remote troubleshooting through advanced telemetry, which significantly reduces vehicle downtime and optimizes energy consumption. This shift transforms vehicle lifecycle management, allowing fleets to detect faults early and resolve many issues remotely, thereby improving operational efficiency and reducing reliance on physical dealer visits.

The rise of subscription-based and feature-on-demand models introduces both flexibility and complexity for fleets, as operators can activate vehicle functions as needed but must navigate intricate pricing structures and ownership rights. Understanding whether features are included upfront, purchased permanently, or tied to recurring payments becomes critical for managing costs and maximizing utility within fleet operations.

Enhanced vehicle connectivity and cloud integration, while enabling sophisticated fleet management capabilities, simultaneously escalate cybersecurity and data governance risks. Fleets and manufacturers must implement stringent access controls, maintain traceable update processes, and ensure resilience across vehicle and cloud environments to safeguard sensitive data and maintain operational integrity amid growing digital vulnerabilities.

In a landmark collaboration, Tata Communications and Tata Motors have integrated built-in 5G connectivity into the Sierra.ev, leveraging Tata Communications’ MOVE platform alongside Tata Motors’ N.IO software-defined vehicle platform. This integration enables seamless streaming, faster over-the-air updates, and real-time remote diagnostics, setting a new benchmark for premium electric vehicles in India by embedding 5G technology at the manufacturing stage and addressing the rising consumer demand for connected car ecosystems.

This partnership not only advances India’s software-defined vehicle ecosystem but also strengthens Tata Communications’ role as a key enabler of next-generation mobility solutions, expanding its high-margin digital and IoT services portfolio. Drawing on its global experience powering connected vehicles like Jaguar Land Rover EVs, Tata Communications is capitalizing on the emerging high-value B2B segment in telecom infrastructure, establishing factory-fitted 5G as the new standard for premium EVs in the domestic market.

Beyond connectivity, the collaboration supports a suite of advanced features including subscription-based services, AI-enabled applications, and safety-critical functions such as emergency calls and remote diagnostics, making vehicles future-ready and scalable for evolving digital capabilities. As Vivek Manglik, EVP at Tata Communications, emphasized, this 5G-enabled digital backbone forms the central fabric for fostering innovation and scaling intelligent vehicle ecosystems, perfectly aligning with Tata Motors’ vision of continuously connected digital experiences.
