Xiaomi SU7 EV crash test generates 5 stars

The top variant of Xiaomi SU7 has a robust safety net with 1 lidar, 11 cameras, 3 radars and 12 ultrasonic sensors

After laying a solid foundation for consumer electronics, Xiaomi is now making bold progress in the field of electric vehicles (EVs). The brand’s first electric car was the SU7 sedan, with four versions. The Xiaomi SU7 is already on the list of best-selling electric vehicles in China, requiring a selection of variants to be waiting for up to 12 months. The future prospects look great, as the Xiaomi SU7 is rated as the safest car by C-NCAP. Let’s check the details.

Xiaomi SU7 C-NCAP crash test results

As of now, there are four variants of Xiaomi SU7 – SU7, SU7 Pro, Su7 Max and Su7 Ultra. For C-NCAP crash tests, the SU7 MAX variant was selected. The security kit for the Xiaomi SU7 Max variant includes 7 frames, a 360° security system and a range of ADAS features.

In addition, the sedan uses a lightweight but sturdy steel alloy armored chassis. The SU7 has two formats of autonomous driving systems. While 11 HD cameras, 12 ultrasonic sensors and 3 mmwave radar are common, the largest (Pilot Max) system has an additional HESAI AT128 lidar. As revealed in recent videos, in certain cases, the LiDAR system can perform better than the camera-based ADAS system.

In the C-NCAP crash test, Xiaomi SU7 received a 5-star rating. The overall safety score was 93.5%, 8.7% higher than the average score in the C-NCAP results. While the 5-star safety rating itself is commendable, the Xiaomi SU7 scored the highest score in all the cars tested by the C-NCAP under the 2024 test protocol. It essentially makes the Xiaomi SU7 the safest car in China. It is indeed a major achievement, especially considering the doubts expressed by some critics about the safety of the sedan.

Crew protection

Xiaomi SU7 scored 94.31% in the occupant protection test. It includes side rod collision test, frontal lobe collision test, child protection, whiplash test, electronic call and curtain airbag test. In most of these tests, the Xiaomi SU7 received a full score or nearly full score.

There are only a few exceptions in the Whiplash test, such as 7 points for 7 points. This is relatively low compared to other occupant protection test scores. When assessing child safety, Xiaomi SU7 scored all three of the three points. The total score of the occupant protection test was 106.573 out of 113.

Active safe, vulnerable road users

In the active safety category, Xiaomi SU7 scored 95.25%. On tests that evaluate headlights and automatic emergency braking (AEB), the score was close to 100%. LiDAR plays a key role in ensuring that the SU7 gets high scores in evaluating driver assistance systems.

In the Vulnerable Road User (VRU) test, the Xiaomi SU7 scored 90.42%. These tests include pedestrian leg and head protection as well as AEB functionality. Compared with the C-NCAP average, SU7 performed 13.14% higher in these tests.
