The impact resistance performance of the Tesla Model Y sunroof has demonstrated excellence in numerous authoritative tests and real-world evaluations.
According to relevant test data from the China Insurance Automotive Safety Index (C-IASI), the Tesla panoramic sunroof can withstand approximately 9.6 tons of pressure-an impact resistance capability superior to that of standard metal car roofs. This performance ensures that, in scenarios involving falling objects from heights or minor collisions, the sunroof provides effective protection for vehicle occupants, thereby mitigating safety risks.
**Capable of Withstanding ~9.6 Tons of Pressure:** Based on relevant C-IASI test data, the Model Y panoramic sunroof can withstand approximately 9.6 tons of static pressure-a figure significantly higher than the compressive strength of a standard metal roof.
**Equivalent to 5–6 Times the Vehicle's Curb Weight:** Tests conducted by C-IASI and various media outlets have demonstrated that the Model Y's glass roof structure can withstand a load equivalent to 5 to 6 times the vehicle's total weight. Based on the Model Y's curb weight of approximately 2 tons, this translates to an ability to withstand an impact force of 10 to 12 tons.
**"Glass Sandwich" Structural Design:** The design employs a two-layer, high-strength laminated glass structure with a sound-insulating interlayer embedded between them (certain high-trim models also feature an electrochromic film). The outer layer consists of tempered glass, while the inner layer is laminated glass; this configuration ensures that, in the event of breakage, the glass fragments do not scatter.
The Model 3 and the standard version of the Model Y are equipped with a fixed panoramic sunroof featuring the aforementioned standard laminated glass composition. High-trim versions of the Model Y, however, feature a dimmable panoramic sunroof; this variant incorporates an embedded electrochromic film within the glass structure, allowing for the adjustment of light transmittance via electric current, while still retaining the high-strength laminated glass structure for the outer layer to ensure that safety performance remains uncompromised.
