Xiaomi New SU7 Max Dual-Zone Smart Dimming Sunroof Adjustment Speed & Performance
How is the adjustment speed of the dual‑zone smart dimming sunroof on the new‑generation SU7 Max?
The dual‑zone smart dimming sunroof equipped on the new‑generation SU7 Max uses the latest generation of EC dimming glass, and its adjustment speed is significantly improved compared with traditional sunroofs.
Switching between Tint Mode and Transparent Mode takes approximately 2 minutes, and the shading rate in Tint Mode can reach up to 99.85%, delivering excellent sun‑blocking performance.
In terms of materials and craftsmanship, this sunroof features a double‑layer silver‑coated + Low‑E coated laminated glass design, with a 99.9% blocking rate for both ultraviolet and infrared rays.
The PVB material in the laminated glass not only improves the vehicle’s overall sound insulation but also effectively blocks ultraviolet rays.
The silver ions in the silver‑coating process strongly reflect infrared rays, which can effectively lower the interior temperature by 10–15°C under strong sunlight. Actual tests show its thermal insulation effect is comparable to physical sunshades.
We also share a useful tip: while reflecting infrared rays, the silver ions in the silver‑coating process also reflect part of the blue light. Since the human eye is more sensitive to blue light, the sunroof glass will appear slightly blue in Transparent Mode. This is a normal optical effect.
