ZF LIFETEC is to showcase a pioneering steering wheel concept at IAA Mobility from September 9 to 12, 2025 (Hall A1, Stand D30).
The concept responds to the transformation that vehicle interiors will undergo in the future in the age of automated driving. The steering wheel system from ZF LIFETEC features an internal electric drive unit that folds the rim downward in approximately two seconds – giving car manufacturers the option to integrate a smooth, silent retraction into the dashboard.
This creates space for flexible, individual interior concepts. The transformable steering wheel offers greater comfort and space in the parking position, as well as in future automated driving modes.
"With the Transformable Steering Wheel, we have developed a forward-looking concept that establishes a context-dependent connection between manual and automated driving," explained Harald Lutz, ZF LIFETEC. "It combines classic functionality with new freedom in interior design."
Quick and quiet switches between driving modes
The concept is based on a traditional steering wheel, complete with all familiar controls. The driver's airbag is integrated into the centre hub of the new transformable steering wheel.
In automated driving situations or in the parking position, the steering wheel rim can be folded downwards. Depending on the vehicle manufacturer's interior concept, car manufacturers can use this to retract the steering wheel rim into the dashboard.
With a folding time of just two seconds, the steering wheel enables quick transitions between driving modes. A light element in the centre uses colour differentiation to clearly indicate the current mode, ensuring easy recognition even in low-visibility conditions such as nighttime driving.

Compact technology for greater interior freedom
Vehicles are being used by consumers for various purposes. They are spending more time inside them, whether for work, relaxation, or consuming multimedia content.
This is particularly evident in Asian markets, where there is a clear demand for spaces that seamlessly blend comfort and functionality. The idea behind ZF LIFETEC’s transformable steering wheel is to support the evolution of future vehicle interiors. It creates additional space during parking phases or automated driving and enables the development of flexible, customizable interior concepts.
With its integrated anti-pinch protection, the steering wheel also ensures maximum safety in everyday use. This system protects limbs – such as fingers or hands – from being trapped during movement.
ZF LIFETEC’s transformable steering wheel concept can be adapted to meet customer-specific requirements, providing flexible solutions for various application scenarios. Depending on the use case, integration requirements can be addressed through a tailored development approach.
