As vehicles evolve into intelligent, software-defined systems, data connectivity emerges as a critical enabler of automotive innovation. From autonomous driving to smart interiors and zonal architecture, the ability to transmit and process data in real time transforms how vehicles are designed, built, and experienced.

We interviewed Mathias Oehrle, Data Connectivity Engineering Lead at Voltaira, to explore the key trends shaping the future of automotive connectivity and how Voltaira is helping lead the transformation.

What Is Data Connectivity?

Matthias Oehrle describes data connectivity, at its core, as the transfer of signals between different systems within a vehicle. As software-defined vehicles, ADAS, and other technologies advance, much more data needs to be transferred simultaneously. Oehrle says, “This is why connectivity is no longer just a support function—it’s becoming central to innovation in the automotive industry. “

Oehrle adds, “Modern vehicles rely on a growing number of sensors and cameras that generate massive volumes of data. These signals must be transmitted in near real-time to enable functions like image recognition, decision-making, and safety interventions.”

Key Trends Shaping Data Connectivity Architecture

1. Autonomous Driving

“Automation means autonomous driving. It is one of the most visible and transformative trends in the industry.” says Oehrle. “Another key driver is entertainment, because you will have many more screens inside the car.” Higher levels of autonomy demand ultra-fast data handling, while passengers will expect rich media experiences. At the same time, interior sensing technologies are emerging, allowing the car to monitor where the driver is looking or even detect vital signs.

“They may even monitor vital signs of the driver. For example, many accidents are caused by heart attacks. The car could detect such an event and respond to avoid a severe accident.”

While most vehicles today operate at level 2 autonomy, higher levels are on the horizon. “A German car maker just announced a level 4 robotaxi will be introduced in the next two years. Another well-known OEM is already testing its model. The shift to autonomous driving requires ultra-fast, low-latency data transmission. This can only be delivered with advanced connectivity and edge computing.” says Oehrle.

2. Edge Computing

Edge computing enables vehicles to process data locally, reducing latency and improving reliability. As Oehrle says, it is crucial that data is processed where it is created: at the sensors or very close to them. “The longer the cable, the more OEMs and automotive suppliers compromise on data quality.” This is especially critical for time-sensitive applications like ADAS, interior sensing, and V2X communication.

3. Zonal Architecture and Software-Defined Vehicles

Traditional vehicle architecture relies on numerous electronic control units (ECUs), each dedicated to a specific function. Zonal architecture consolidates these into fewer, more powerful computing zones. “In the future of automotive architecture, a central vehicle computer will serve as the brain of the car, while zonal ECUs will manage local functions within each physical zone. This approach significantly reduces wiring, lowers system complexity, and improves scalability and efficiency.” says Oehrle. This shift not only simplifies manufacturing but also supports continuous software updates—turning vehicles into upgradable platforms, much like smartphones.

4. Smart Interiors and In-Cabin Sensing

Connectivity is also transforming the in-cabin experience. Vehicles are increasingly equipped with sensors that monitor driver attention, passenger health, and more. “Checking vital values of the driver will contribute to fewer or less severe accidents. We, at FIT Group, are also allocating resources to the development of biometric detection sensors. These innovations will enhance safety and open the door to personalized, responsive vehicle environments.”

5. Vehicle-to-Everything (V2X) Communication

V2X enables vehicles to communicate with each other and with infrastructure, improving traffic flow and safety. “If there’s an accident for example, it automatically pops up in the vehicle navigation guide, and planned routes can be instantly adjusted. However, this also raises cybersecurity concerns, making robust protection measures essential.” says Oehrle.

Voltaira’s Vertical Integration: A Competitive Advantage

“As Voltaira, the mobility business unit of Foxconn Interconnect Technology, we have a strong advantage in vertical integration.” says Oehrle. “With deep expertise at the component and subsystem levels, we offer more than just parts— we deliver integrated application, module, and component solutions. Our approach enables us to support our customers as a trusted, end-to-end technology partner.”

Voltaira designs and produces components such as Fakra, Mini-Fakra, and Automotive Ethernet connectors, as well as modular connectors, and delivers complete cable assemblies and modules. This end-to-end expertise enables flexibility, innovation, and speed—key success factors in the fast-changing automotive market.

Looking Ahead: The Software-Defined Future

Over the next five to ten years, Oehrle sees software-defined vehicles, zonal architecture, and smart sensing as the biggest drivers of change in data connectivity.

Oehrle also mentions the importance of sustainable solutions, “While sustainable solutions may currently come with greater expense, they could become a unique selling point in the future, distinguishing companies whose components and systems actively support sustainability.”

With over 450 engineers and more than 1,100 patents, Voltaira Group, the mobility business unit of Foxconn Interconnect Technology, is building the digital backbone of tomorrow’s transportation—delivering intelligent, secure, and sustainable connectivity solutions that keep customers ahead of the curve.

Connectivity is reshaping the automotive industry, and we are enabling the infrastructure that makes it all possible.
