en.Wedoany.com Reported - On June 5, Tesla Vice President Tao Lin discussed window glass topics on Weibo, stating that Tesla engineers have adopted chemically tempered glass for the windows, reducing the inner glass layer thickness to 1.1 mm, increasing overall hardness by approximately 25%, and reducing the vehicle's weight by 2 kg.

Tao Lin pointed out that the industry's commonly used double-layer laminated windows stack two 2.6 mm thick glass sheets together, making them extremely difficult to break from the inside in emergencies. Tesla's solution reduces the time needed to break the window for escape in critical situations by dozens of times compared to traditional window glass. Tao Lin stated that these figures may not appear in the specification sheet, but engineers will do their utmost to ensure safety.

Xiaomi founder, Chairman, and CEO Lei Jun subsequently reposted Tao Lin's Weibo, stating that the inner glass layer of the double-layer windows in Xiaomi YU7 and the new SU7 also uses 1.1 mm thick chemically tempered glass.

Lei Jun commented that, after consulting engineers, this solution is consistent with Tesla's current approach, both using double-layer laminated glass, which improves NVH and lateral sun protection performance while ensuring safety and quality.
