“DURABIO” plant-derived bioengineering plastic adopted for the crystal-shade AI speaker in Dongfeng Nissan’s “Teana”

Mitsubishi Chemical Corporation (Head Office: Chiyoda-ku, Tokyo; President: Manabu Chikumoto; hereinafter “MCC”) announces that its plant-derived bioengineering plastic “DURABIO™” has been adopted for the AI speaker components in the new “Teana” that was launched in China by Dongfeng Nissan Passenger Vehicle Company* in November 2025. 

DURABIO™ is a bioengineering plastic primarily made from plant-derived isosorbide. Compared to conventional polycarbonate resins, it features higher transparency and superior optical properties. While being a plant-derived polymer, the material is also excellent in weather resistance and durability.
 
The top of the dashboard of the new “Teana” features an AI speaker that enables voice-based interaction and operation. The speaker has an inverted pyramid design. When illuminated, six light pillars rhythmically emit light in 256 colors and create a crystal-like, colorful, and transparent texture, bringing a sense of dynamism to the interior of the car.
 
DURABIO™ was selected for its high designability such as superior transparency and optical properties, making it suitable for creating a luxurious and vibrant car interior space, as well as for its high durability that makes it a resin usable without requiring a clear coat.
 
MCC will continue to provide high-value-added products by expanding the DURABIO™ lineup.
 
*Dongfeng Nissan Passenger Vehicle Company is a Chinese joint venture between Nissan Motor Co., Ltd. and Dongfeng Motor Group.
