In the fast-evolving automotive industry, innovation plays a pivotal role in building strategic relationships and maintaining a competitive edge. As companies push the boundaries of what’s possible, advancements in autonomous driving, electrification, and connected technologies are transforming the landscape.

“Automotive OEMs and mobility suppliers seek future-proof solutions, not just short-term cost savings” explains Zsolt Rehak, leader of advanced engineering at Voltaira.

Partnering with a supplier that has an R&D mindset provides access to superior, forward-thinking solutions that set companies apart. Martin Schloms, leader of advanced engineering at Voltaira Autokabel, cites aluminum as an example: “Autokabel Group was a pioneer in aluminum technology. At the time, aluminum busbars were new and different, offering unique properties and processes that set us apart from others in the market.”

How Change is Happening: The Role of OEMs and Strategic Partnerships

Innovation in the automotive industry is a collaborative effort. OEMs drive the demand for new technologies, while suppliers translate those needs into tangible solutions. “For example, the shift to 48-volt systems, which enhances energy efficiency in electric vehicles, was first pioneered by suppliers before being widely adopted by OEMs,” says Schloms.

Strategic partnerships between suppliers and OEMs accelerate innovation. Rehak emphasizes, “Getting closer to the customer is a top priority for mobility suppliers. Understanding their direction is critical for staying ahead of the curve.” Companies that engage in early, strategic collaboration will lead the way in shaping future automotive technology.

Major Trends Shaping the Future of Automotive Technology

While large-scale changes in vehicle architecture have traditionally been slow, the next decade will bring significant transformations. “For 15 years, the industry has been exploring new main body harness architectures, but the system has remained largely conservative,” says Schloms. But with new players and new perspectives, innovation is accelerating.

OEMs that embrace innovation not just in customer-facing features but also in basic components—such as cables, materials, and fasteners—will be the ones driving the next generation of vehicles.

1. Autonomous Driving

Many wonder when the highest possible autonomy will be reached. The answer: It’s closer than you think. While fully automated vehicles already exist, the real challenge is regulatory approval. This shift will require a complete overhaul of a car’s electrical architecture. Today’s traditional “wire harnesses” are not designed to handle the increased power and data demands of autonomous vehicles. “Voltaira and Voltaira Autokabel are actively developing components such as busbars and connectors to meet these evolving requirements”, says Schloms.

2. Sensor Expansion

Next-generation vehicles will require an increasing number of sensors to enhance safety and autonomous driving. This expansion is critical for full self-driving capabilities and maximum safety—monitoring the car’s interior, the driver’s condition, and the surrounding environment, including roadblocks and traffic situations. According to Rehak, the number of sensors in vehicles could multiply, marking a significant increase.

3. Steer-by-Wire Systems

Traditional EPS steering systems will soon be replaced by steer-by-wire systems. OEMs are already testing and selling these new solutions, which will eventually eliminate steering columns altogether. Rehak predicts that steer-by-wire technology will become a widespread trend within the next decade, significantly improving vehicle efficiency and design flexibility.

4. Globalization of R&D and Innovation

Innovation is no longer confined to a single region. Key players in Europe, the U.S., and Asia are operating at the same level, fostering a new era of global collaboration. “The days of a sequential, one-market-at-a-time approach are behind us. Innovation happens everywhere, and companies can no longer rely on a single regional headquarter to lead development,” Rehak says. Expanding global networks is crucial for staying competitive.

5. Faster R&D Cycles Through Simulation and Virtual Testing

In today’s digital, hyper-connected world, the speed of innovation is critical. Suppliers need to bring ideas to market faster than ever. The rapid exchange of information is transforming R&D, not just in the development phase but also in how products are realized. Virtual testing and simulation allow suppliers like Voltaira to reduce excessive development loops and reduce the need for physical prototypes. “From virtual testing to seamless software integration, the tools of the future will enable automotive suppliers to work faster, smarter, and more efficiently,” says Schloms.

Choosing a Strategic Supplier Partner That Delivers Value
