Quick Takeaways
  • Smart glazing is now moving from concept to showroom reality as FORVIA HELLA and Fuyao scale up production in China.
  • The technology directly improves cabin comfort and EV efficiency while opening new possibilities for connected interiors.
FORVIA HELLA intelligent glass was officially confirmed to be in mass production in China following a joint development program between Hella GmbH & Co. KGaA (FORVIA HELLA) and Fuyao Glass Industry Group Co., Ltd. The advanced glazing solution is already being delivered to multiple Chinese automakers, marking a significant step in smart automotive interior technology.
This FORVIA HELLA intelligent glass solution merges Fuyao’s large-scale automotive glass engineering capabilities with FORVIA HELLA’s electronic control expertise. The result is a switchable glass system that allows real-time adjustment of transparency while also providing active protection and comfort functions across multiple vehicle glazing areas.
FORVIA HELLA intelligent glass for smart vehicle glazing
The technology is engineered for use in panoramic sunroofs, side windows, and other transparent vehicle surfaces where adaptive light control and privacy are critical. By integrating electronic control units directly with the glass system, the solution enables fast and precise switching between different transparency levels based on driving conditions and passenger needs.
Key functional advantages include:
  • Wider outward visibility with reduced glare
  • Adjustable natural light levels inside the cabin
  • Instant privacy control for passengers
  • Enhanced thermal and UV protection

The intelligent dimming capability automatically adapts to weather conditions and user preferences, blocking ultraviolet and infrared radiation when required. This lowers heat buildup inside the vehicle, reducing the workload on air-conditioning systems and improving overall cabin comfort.
Energy efficiency and EV range benefits
By limiting solar heat gain, the system helps decrease energy consumption, which is particularly important for electric vehicles. Lower cooling demand allows EVs to use less battery power for climate control, supporting longer driving range and improved energy efficiency without compromising passenger comfort.
The electronic control unit integrated into the glazing architecture also enables future-ready digital functions. Beyond managing transparency, it supports communication and entertainment-related features, allowing the glass to become part of the vehicle’s connected and intelligent interior environment.
With mass production now underway and supply already reaching domestic automakers, the collaboration between FORVIA HELLA and Fuyao demonstrates how electronics and materials innovation are converging to redefine how vehicle glass contributes to comfort, efficiency, and digital experiences.
