In previous articles, OT has introduced the SDV strategies of several leading players across the automotive ecosystem, including Infineon, NXP, Qualcomm, BMW, and Mercedes-Benz. Interestingly, despite their different positions in the value chain—ranging from top-tier IC design companies to global automakers—they have all highlighted their own approaches to SDV. This naturally leads to a bigger question: what exactly is SDV? In this article, OT will not only explain what SDV really means, but also explore the technical requirements behind it, as well as the future trends shaping its development.

When people used to talk about the automotive industry, the first things that came to mind were engines, chassis, transmissions, vehicle platforms, and a competitive logic built primarily around mechanical performance. But in recent years, the center of gravity has shifted rapidly: software is no longer just a supporting layer, but increasingly the main driver of value.
Today, it is not only automakers that are talking about SDV. Major Tier 1 suppliers, automotive semiconductor companies, and platform providers are all treating software-defined vehicles as one of the defining themes of the next decade in mobility. If there is one company that best represents this trend in practice, it is difficult to ignore Tesla. The reason is not simply its EV sales or brand visibility, but the fact that Tesla turned OTA updates, continuous feature iteration, and software-driven product evolution into a user experience the market can actually see and feel. In Tesla’s case, the idea that a car can continue evolving after delivery is no longer just a concept. It has become a recognizable product model.
What Is an SDV?
When people first hear the term SDV, they often assume it simply means “a car with lots of software in it.” But the real point is not the quantity of software. The real point is this: more and more of a vehicle’s functions, differentiation, and upgrade potential are being defined by software.
In other words, SDV does not mean hardware is no longer important. It means that hardware is no longer the only core source of value. In the traditional automotive era, a vehicle’s functionality was largely fixed the moment it left the factory. Under an SDV model, however, the vehicle becomes more like an updatable platform. Buying a car is no longer just buying a fixed set of features; it is buying a foundation that may continue to expand, improve, and generate new services throughout its lifecycle.
That is why the smartphone analogy is so often used in discussions of SDV. What changes product competitiveness is no longer only hardware specification, but also platform capability and software lifecycle management. In that sense, SDV is not simply a new technical label. It reflects a deeper change in how vehicles are designed, delivered, operated, and monetized.
What Does SDV Include, and What Technical Upgrades Does It Require?
SDV matters because it is not a single-point technology. It is a systemic shift that affects the entire vehicle architecture and the broader supply chain.
The first foundational change is the upgrade of the E/E architecture. In conventional vehicles, there are often many distributed ECUs inside the car, each responsible for a specific function and interconnected through complex wiring harnesses and in-vehicle communication networks. As vehicles begin to support more advanced cockpit computing, connected services, driver assistance, and continuous software delivery, this highly distributed architecture becomes harder to scale. The industry is therefore moving toward more centralized computing and zonal architectures, in which fewer but more capable computing nodes coordinate broader sets of functions.
The second major dimension is the upgrade of the software platform itself. SDV is not simply about writing more software into ECUs. It requires stronger platform-level capabilities, including operating systems, middleware, virtualization, development frameworks, toolchains, testing infrastructure, and reusable software bases across vehicle programs. In the SDV era, the key question is no longer only how powerful an individual chip is, but whether the underlying platform can support scalable development, long lifecycle maintenance, and efficient feature deployment across different models.
The third dimension is OTA and vehicle-cloud collaboration. When people hear SDV, they often think first of OTA, and that is understandable. But OTA is much more than remote updates. It represents software asset management, validation, rollback mechanisms, version governance, fleet operations, and ongoing service delivery. Once software becomes a continuous part of the product, automakers and suppliers need the infrastructure and governance to update vehicles safely and repeatedly over time.
The fourth dimension is AI and the data feedback loop. Future vehicle competitiveness will not depend only on sensors and compute hardware, but also on whether automakers and suppliers can build a full loop of data collection, model improvement, cloud-based development, and edge deployment in the vehicle. This makes SDV not only a software issue, but also a data issue, a cloud issue, and increasingly an AI issue.
Future Trends and Development of SDV
Looking at the industry’s current direction, the next few years of SDV development are likely to deepen along several major lines.
First, centralized computing and zonal architectures will continue to spread. This does not mean every vehicle will shift to the same architecture overnight, but the overall trajectory is increasingly clear. Functions are gradually moving away from large numbers of distributed controllers toward fewer but more capable central or zonal platforms. This shift helps reduce complexity while also making software integration, cybersecurity governance, and lifecycle updates more manageable.
Second, AI will penetrate more deeply into the cockpit, driver assistance, and vehicle control logic. In the past, automotive AI was often associated mainly with voice recognition or perception tasks. Today, however, the industry is beginning to place generative AI, agentic systems, and vehicle platforms within the same strategic frame. This suggests that future vehicles may not only understand commands better, but also become more capable of context-aware interaction, cross-functional coordination, and proactive service delivery.
Third, the automotive development model will increasingly resemble that of the tech industry rather than traditional manufacturing alone. Once SDV becomes central to vehicle strategy, competition is no longer only about lower hardware cost or stronger supply chain execution. It also becomes about who can develop, validate, deploy, monitor, and iterate software more quickly and more reliably. In other words, the future automotive industry will depend more heavily on software engineering discipline, cloud-linked workflows, and end-to-end platform thinking.
Impact on the Supply Chain
The true impact of SDV does not lie in the upgrade of a single component. It lies in the fact that the value distribution across the entire automotive supply chain is being reshaped.
For automakers, future competitiveness will no longer come only from vehicle platform development, styling, and manufacturing capability. It will increasingly come from platform-level software capability, vehicle-cloud operations, version governance, and control over data and services. As vehicles become more like evolving platforms, carmakers must think beyond the one-time sale and toward continuous product operation over the full lifecycle.
For Tier 1 suppliers, the role is also changing. Instead of focusing mainly on single-function modules, they are gradually moving toward supplying computing platforms, zonal controllers, software frameworks, validation capabilities, and integration services. In the SDV era, value shifts upward from isolated hardware delivery toward system integration and long-term software support.
For IC design companies and platform providers, the rise of SDV is equally significant. It means competition in automotive semiconductors is no longer just about the computing power, interfaces, or power consumption of individual chips. It is now about who can provide a more complete set of capabilities to support SDV.
As a result, more and more IC companies are trying to establish a position in this market, with Qualcomm, NXP, and Infineon among the most prominent and aggressive players. However, their strategies are not the same.
Qualcomm’s approach is more centered on high-performance SoCs, extending into centralized computing, intelligent cockpits, in-vehicle connectivity, and AI platforms. Its ambition is to move beyond the role of a chip supplier and become a platform provider for the software-defined vehicle era.
By contrast, NXP and Infineon are more clearly aligned with the foundational capabilities required by zonal architectures. Their strengths lie closer to the lower layers of the vehicle stack, such as zonal controllers, real-time control, in-vehicle networking, power management, functional safety, and cybersecurity.
If we look more closely, these strategic differences are not difficult to understand. Qualcomm’s strength comes from mobile computing and highly integrated SoC design, which makes it well suited to push from the direction of centralized computing platforms, integrating CPU, GPU, NPU, connectivity, and AI ecosystems into a scalable automotive platform.
NXP and Infineon, on the other hand, have spent years building strength in automotive-grade MCUs, body control, networking, safety, and power devices. Naturally, their SDV entry points are more focused on the foundational nodes that “hold the vehicle together,” such as zonal control, power distribution, communication backbones, diagnostics, and safe power routing.
In other words, SDV is not pushing every IC company toward the same path. Instead, it is making each company’s strengths and strategic positioning clearer. This reflects a broader trend: in the SDV era, the value of automotive semiconductors will no longer depend only on which chip is stronger, but on who occupies the more critical position in the overall architecture.
If we widen the lens further to include surrounding parts of the supply chain—such as Bluetooth, Wi-Fi, GNSS, V2X, automotive modules, cybersecurity, OTA systems, and vehicle-cloud services—the impact of SDV becomes even more significant. In the future, these technologies will no longer be seen as optional add-ons. They will become part of the infrastructure that enables the software platform of the vehicle to keep operating, updating, and connecting over time.
That means supplier competitiveness will no longer rest only on hardware specifications or isolated performance metrics. It will increasingly depend on whether suppliers can support higher-level software-hardware integration, version compatibility, remote operations and maintenance, compliance, and data-enabled services.
The Road Ahead: From SDV to AIDV
SDV is not just a buzzword, and it is not merely a new phrase on automaker presentation slides. What it really represents is this: the center of value in the automotive industry is shifting from hardware alone toward software, platforms, and continuous service capability.
Tesla is often used as the emblem of this shift not simply because it makes electric vehicles, but because it showed the market earlier than most that a vehicle can behave like an evolving platform. And the involvement of players such as Qualcomm, NXP, Infineon, BMW, Mercedes-Benz, and many others makes it clear that this is no longer the path of a single company. It is a direction the entire supply chain is moving toward together.
In the coming years, SDV may not be implemented at the same speed across all vehicle classes or markets, but the overall trajectory is already clear: more centralized architectures, stronger OTA capability, deeper AI integration, and a development model that looks increasingly like the tech industry. For the automotive supply chain as a whole, this is not a minor upgrade. It is a structural redistribution of roles and value. Whoever can seize the capabilities of platforms, software, and continuous services in this transformation will have a far better chance of occupying a critical position in the next era of the automotive industry.
Looking ahead, the rapid advancement of large language models (LLMs) is expected to drive SDV toward its next stage of evolution: AIDV (AI-Defined Vehicle). If SDV represents a shift in which vehicle functionality is increasingly defined by software, then AIDV suggests a further transformation in which AI becomes a deeper layer of decision-making, interaction, and service orchestration inside the vehicle. In this sense, the future trajectory of the automotive industry may extend beyond software-defined vehicles toward vehicles increasingly defined by artificial intelligence.
