ZF Equips NIO ET9 with Cutting-Edge Steer-by-Wire Technology, Paving the Way for Software-Defined Vehicles

(IN BRIEF) ZF is equipping NIO’s ET9 electric vehicle with its advanced steer-by-wire technology, offering a fully electronic steering system that enhances driving comfort, safety, and adaptability. The system is part of ZF’s broader strategy to lead the development of software-defined vehicles. With additional customer orders in Europe and other global markets, ZF is solidifying its role as a pioneer in the by-wire chassis sector.

(PRESS RELEASE) FRIEDRICHSHAFEN , 17-Feb-2025 — /EuropaWire/ — ZF, a leading global technology group, is equipping NIO’s flagship electric vehicle, the ET9, with its advanced steer-by-wire system, marking a significant step forward in automotive innovation. The new system, which eliminates the mechanical connection between the steering wheel and the front wheels, is a breakthrough in the growing field of by-wire technology. ZF is providing NIO with a full suite of components, including the steering wheel actuator, redundant steering gear actuator, and the necessary software to ensure a seamless, responsive driving experience.

Launched in 2024, ZF’s newly established “Chassis Solutions” Division offers a broad range of electronically controlled steering and braking systems, including the steer-by-wire technology. This shift is part of ZF’s broader strategy to support the development of software-defined vehicles, utilizing its cubiX software platform to integrate these systems into a cohesive, adaptable solution for manufacturers.

According to Dr. Peter Holdmann, Member of ZF’s Board of Management and head of the Chassis Solutions Division, “Our steer-by-wire system is not just a technological leap forward; it marks the beginning of the software-defined vehicle era. As a key player in the industry, we are offering car manufacturers like NIO unparalleled design freedom, comfort, driving dynamics, and safety innovations.”

NIO, known for its commitment to revolutionizing the electric vehicle sector, views steer-by-wire technology as a pivotal component of their future offerings. Danilo Teobaldi, Principal Chief Engineer at NIO, expressed, “Steer-by-wire is central to creating vehicles that are not only comfortable but also adaptive to the needs of future driving. Our collaboration with ZF represents a shared vision to push the boundaries of electric mobility and create a new benchmark for the automotive industry.”

Since the strategic partnership between ZF and NIO began in 2022, the companies have worked together to industrialize this cutting-edge technology, positioning NIO’s smart EVs for success on the global stage.

Steer-by-Wire: A Leap Forward in Steering Technology

ZF’s steer-by-wire system employs a mechatronic actuator that provides all steering power, removing the need for any mechanical connection between the steering wheel and the wheels. The system uses a steering wheel actuator that detects the driver’s input, while an electric torque feedback unit delivers road feel, making the driving experience both intuitive and responsive. The steering ratio is dynamically adjusted based on speed and driving conditions, allowing for improved maneuverability, especially at low speeds, such as when parking.

This technology also opens the door for smaller, more compact steering wheels that no longer require drivers to adjust their grip when making tight turns. When combined with ZF’s AKC mechatronic rear-wheel steering, driving comfort is significantly improved, especially in electric vehicles with a longer wheelbase. The steering feel can be customized to suit different preferences, from sporty and direct to more comfortable and relaxed, all while increasing driver safety by eliminating the steering column.

Expanding Market Reach: ZF’s Growing Presence in By-Wire Systems

In addition to its partnership with NIO, ZF’s steer-by-wire technology is being adopted by another major global car manufacturer, with additional orders for the system in Europe. ZF’s success in bringing this technology to market underscores the company’s leadership in developing and industrializing by-wire systems for modern vehicles.

Dr. Holdmann remarked, “The success of our steer-by-wire technology in the series production phase validates our strategy. By offering a comprehensive portfolio of hardware and software solutions for vehicle motion control, we are not only responding to market demands but also actively driving the evolution toward software-defined vehicles.”

As part of the restructuring in January 2024, ZF combined its Active Safety Technology and Car Chassis Technology divisions into a single, unified unit, further strengthening its position as a leader in chassis innovation. This move has already yielded results, with ZF securing a major order for brake-by-wire systems, which will equip nearly five million vehicles globally with electromechanical braking technology.

With its extensive range of by-wire technologies, which eliminate the need for mechanical links and system fluids, ZF is at the forefront of transforming the future of automotive chassis systems.
