ZF Begins Series Production of Steer-by-Wire Technology With NIO

Germany's ZF is equipping NIO’s flagship electric vehicle, the ET9, with its latest generation steer-by-wire system. ZF is supplying both the steering wheel actuator for steering and steering feel as well as the redundant steering gear actuator and associated software.

The ET9 will have no mechanical connection between the steering wheel and the front wheels.

The technology enables possibilities for the development of new, more compact steering wheels that no longer require drivers to change their grip when parking. 

Since the creation of its 'Chassis Solutions' Division at the beginning of 2024, ZF now has a comprehensive portfolio of purely electronically controlled steering and braking systems and controlled damping systems. 

In combination with ZF's cubiX software, these technologies form the basis for software-defined vehicles (SDVs).

Dr. Peter Holdmann, Member of the Board of Management at ZF and responsible for the Chassis Solutions Division, says: "We are supplying customers with the steering of the future. With our production-ready steer-by-wire steering system, we are launching the era of the software-defined vehicle. With an entire portfolio of innovative by-wire technologies, we are a sought-after supplier and a key driver of future-oriented chassis technologies. ZF is firmly establishing itself as a technology leader in this area and giving car manufacturers such as NIO new freedom in terms of design, safety, comfort and driving functions."

Danilo Teobaldi, Principal Chief Engineer at NIO, adds: “At NIO, we are committed to delivering groundbreaking innovations that redefine premium driving experience. Steer-by-wire technology is a key enabler of software-defined vehicles, offering enhanced driving comfort, uncompromised dynamics, and future-proof technology.” 

ZF supplies highly developed products and systems for the mobility of passenger cars, commercial vehicles and industrial technology.
