ZF's By-Wire Chassis Business Is Shaping How Steering, Braking, Damping and Vehicle Motion Are Coordinated Inside the Next Gen of SDVs

Key Takeaways

• ZF's cubiX central algorithm links steering, braking, damping, roll control
• First production steer‑by‑wire in NIO ET9 (2025) and Lotus Eletre (2023)
• Mercedes‑Benz slated for ZF steer‑by‑wire rollout in Europe 2026
• ZF secured brake‑by‑wire program for ~5 million vehicles, deliveries start 2027
• ZF merged safety and chassis units into Chassis Solutions Division Jan 2024

Pulse Analysis

The automotive industry is rapidly moving toward software‑defined vehicles, where the line between hardware and code blurs. ZF’s by‑wire chassis strategy exemplifies this shift by offering a unified control layer—cubiX—that orchestrates multiple subsystems in real time. This approach reduces the need for separate electronic control units, cuts wiring complexity, and enables over‑the‑air updates, positioning ZF as a critical enabler of next‑generation electric vehicle architectures.

Competitors are watching ZF’s rollout closely. While traditional Tier‑1s have long supplied discrete steering racks or brake calipers, ZF’s move to sell the coordination logic forces suppliers to provide higher‑value components such as redundant actuators, fast‑response sensors, and certified software interfaces. The upcoming Chinese steering standard change in July 2026, which eases regulatory hurdles for steer‑by‑wire, further expands the addressable market, prompting OEMs worldwide to consider integrated solutions over legacy hardware stacks.

For investors and strategists, ZF’s restructuring signals a broader industry trend: the monetization of vehicle‑level software platforms. By consolidating Active Safety and Chassis technologies into a single division, ZF aligns engineering, procurement, and product development around a common digital backbone. This not only accelerates time‑to‑market for new EV models but also creates recurring revenue streams through software licensing and data services, reshaping the profit dynamics of the automotive supply chain.
