As deliveries of the Xiaomi SU7 commence， a common dilemma for new car owners arises: whether to apply window tinting. While most vehicles benefit from aftermarket tinting for enhanced heat and UV protection， Xiaomi has proactively addressed this concern regarding the SU7.

Xiaomi’s official response to user inquiries clarifies that additional window tinting is generally not necessary for the SU7. This recommendation stems from the vehicle’s advanced integrated glass technology designed for superior thermal and solar rejection.

The company emphasizes that optimal sun protection and heat insulation are primarily determined by the performance of the sunroof and windshield， as these glass surfaces are exposed to direct sunlight and have the largest surface area.

Xiaomi SU7’s Front Windshield and Panoramic Sunroof: A Technological Advantage

Across all SU7 models， the front windshield features laminated glass combined with a triple-silver-coating process. This advanced construction achieves an impressive 99.5% UV rejection rate and a 97.6% infrared (heat) rejection rate.

For the Standard and Pro versions of the SU7， the panoramic sunroof also utilizes laminated glass but incorporates a double-silver-coating process. This results in a 99.9% UV rejection rate and a remarkable 99.1% infrared rejection rate， offering substantial protection against both harmful UV rays and external heat.

Further enhancing the thermal management， the Xiaomi SU7 Max model boasts a next-generation electrochromic (EC) dimming sunroof. This feature not only provides maximum light blockage of 99.85% but also achieves a superior 99.9% rejection rate for both UV and infrared radiation， significantly elevating the cabin’s thermal comfort.

The attention to detail extends to the side windows. All SU7 models are equipped with laminated glass on the four doors， offering a 99.9% UV rejection rate. The front side windows have an infrared rejection rate of 77.23%. To further improve passenger comfort and privacy， the rear windows employ privacy glass， which boosts the infrared rejection rate to 80.09%.

Real-World Performance and Smart Features

In rigorous testing， the Xiaomi SU7 was subjected to a 38°C (100.4°F) environment for 1.5 hours. The results indicated that the interior temperature remained lower than that of some vehicles equipped with physical sunshades， underscoring the effectiveness of its integrated glass technology.

Based on these specifications and performance data， Xiaomi suggests that the SU7’s glass offers excellent solar and heat protection， sufficient for the needs of most users， thus making additional tinting an optional consideration rather than a necessity.

To further enhance occupant comfort， the Xiaomi SU7 is equipped with an in-cabin high-temperature protection feature. Should the vehicle be parked under prolonged heat exposure， users can activate this function via the settings menu. The system will monitor the internal temperature and automatically engage the climate control system to actively cool the cabin， ensuring a more comfortable environment upon re-entry.
