AGC's Light-control Panoramic Roof with Low-E Coating Adopted in LEXUS RZ, Toyota LEXUS' First Dedicated BEV Model
TOKYO, May 11, 2022 /Kyodo JBN-AsiaNet/ --

AGC Inc., a Tokyo-based world-leading manufacturer of glass, chemicals and 
high-tech materials, has developed a light-control panoramic roof with Low-E 
coating, which has been adopted for the LEXUS RZ, a dedicated BEV (*1) model to 
be launched by Toyota Motor Corporation in the second half of 2022. The use of 
Low-E glass (*2) with high solar control and heat-insulating performance allows 
the panoramic roof to provide both an open cabin environment and a comfortable 
cabin temperature, while the elimination of a sunshade contributes to a lighter 
body.

While conventional panoramic roofs let in light and create an open interior 
space, they are susceptible to solar heat and outside temperature, requiring 
sunshades to keep the cabin comfortable and preventing occupants from fully 
enjoying the open feeling due to heat and cold issues.

The special Low-E coating technology developed by AGC recently for automotive 
glass has cleared the reliability evaluation required for the LEXUS brand, 
which pursues high quality and advanced features. It has also achieved 
unprecedented solar control and heat-insulation performance, thereby greatly 
reducing heat in summer and cold in winter, which had been an issue. The 
shade-less configuration also contributes to vehicle weight reduction and head 
clearance (the distance from the top of the head to the ceiling when seated).

Furthermore, a light-control type is also available to instantly control the 
transmitted light and adjust the light environment inside the cabin, providing 
new enjoyment, comfort, and experiential value to the LEXUS brand in the new 
era.

The AGC Group has positioned the mobility business as a strategic business 
under its medium-term management plan "AGC plus-2023." AGC will contribute to 
the realization of new mobility and a sustainable society by providing optimal 
materials and solutions as the functions required of automotive glass diversify 
with the advancement of CASE.

Notes:
(*1) BEV: Abbreviation for Battery Electric Vehicle
(*2) Low-E glass: Abbreviation for low emissivity glass. Glass coated with a 
special metallic film reduces heat transfer by radiation and has high solar 
control and heat-insulating performance.
