IT Home News, March 26 - Xiaomi Auto released its 133rd Q&A session last night, addressing questions about what C-NCAP is, what it means for SU7 to have a comprehensive score rate of 93.5% in C-NCAP, and the impact of plateau environments on vehicles.

IT Home has attached the Q&A content from Xiaomi Auto as follows:

C-NCAP stands for China New Car Assessment Program. What are the differences between the 2024 version of the new regulations and the previous testing rules?

C-NCAP is the "China New Car Assessment Program" initiated by the China Automotive Technology and Research Center.The aim is to conduct comprehensive and rigorous safety performance tests on vehicles, including occupant protection, vulnerable road user (VRU) protection, and active safety, in order to provide consumers with more systematic and objective vehicle safety information.

The 2024 version of the C-NCAP evaluation regulations includes a total of 23 changes.11 new items、12 revisionsThe overall testing dimensions are more comprehensive and the difficulty is higher, for example:

• Full-overlap rigid barrier collision: Impact speed increased from 50 km/h to 56 km/h.

• Deformable Moving Barrier Side Impact: Collision speed increased from 50 km/h to 60 km/h, barrier weight increased from 1400 kg to 1700 kg.

• Side pole collision: Add rear row child dummies, distant occupant assessment, etc.

Even so, the Xiaomi SU7 still achieved a comprehensive score rate of 93.5%, ranking among the tested models in C-NCAP (2024 version).First placeXiaomi SU7 has achieved top marks in all safety tests, completing the full set of safety certifications.

• C-NCAP五星 certification, with the highest comprehensive score rate in the 2024 regulation version.

• The only sedan to date to have achieved a G/A rating in the new C-IASI tests.

• 2024 China Smart Car Index highest rating, achieved 4G+ excellence.

• 2024 Annual Top Ten Vehicle Body Evaluation by the China Automotive Technology and Research Center, awarded the "Best Structural Award" and "2024 China Top Ten Vehicle Bodies" authoritative certification.

Xiaomi Auto will continue to work hard, constantly improving safety performance to deliver high-quality, safer vehicles to everyone.

The comprehensive score rate of Xiaomi SU7 in C-NCAP being 93.5% means what? (The original sentence is a question, and the translation maintains its interrogative form.) For a direct statement without the question format: The comprehensive score rate of Xiaomi SU7 in C-NCAP is 93.5%.

Xiaomi SU7 in C-NCAP evaluation resultsThe overall score rate reached 93.5%.The Xiaomi SU7 ranks first among the tested models in C-NCAP (2024 version), achieving an excellent score that fully demonstrates its outstanding safety performance. Additionally, the Xiaomi SU7 also ranks first in the 'VRU Protection' and 'Active Safety' testing categories among the tested models in C-NCAP (2024 version), while its score in 'Occupant Protection' is the highest among all tested passenger vehicles in C-NCAP (2024 version).

Xiaomi汽车始终坚信，安全没有捷径，我们始终坚持以最严苛的安全标准来设计我们的产品。Xiaomi SU7的铠甲笼式钢铝混合车身在碰撞时能有效分散和抵御冲击力，在碰撞测试中均表现出色；在设计上，我们也充分考虑了对乘员及行人的保护，能有效减少事故伤害。此外，Xiaomi SU7Standard configuration of 16 active safety features., which can real-time dynamically monitor various vehicles, pedestrians, and two-wheelers in the forward and side rear directions of the road, promptly issue warnings, and intervene in braking or steering correction when necessary, to尽可能避免或减缓碰撞事故。 改正后的翻译： , which can real-time dynamically monitor various vehicles, pedestrians, and two-wheelers in the forward and side rear directions of the road, promptly issue warnings, and intervene in braking or steering correction when necessary, to avoid or mitigate collision accidents as much as possible.

It is worth mentioning that Xiaomi Automobile isSafety with low-end and high-end configurations from the same source and no optional packages.The safety design goals for all models are top-tier high standards.

What upgrades have been made to the active safety test items in the C-NCAP 2024 version?

In addition to the conventional testing items for active safety features such as AEB (Automatic Emergency Braking), FCW (Forward Collision Warning), LDW (Lane Departure Warning), LDP (Lane Departure Prevention), ELK (Emergency Lane Keeping), and RCTA (Rear Cross Traffic Alert), the C-NCAP 2024 version regulations pose greater challenges to active safety functions. New tests have been added for pedestrian crossing scenarios at intersections, AEB misactivation scenarios, and the speed requirements for night-time pedestrian collision avoidance have been increased.

Even though the new regulations are more challenging, Xiaomi SU7's active safety still...95.25% score rateThe vehicle ranks first among tested models in the C-NCAP (2024 version). All Xiaomi vehicles are equipped with 16 active safety features. With breakthroughs in sensor perception performance, fusion algorithms, and actuator response, they can comprehensively and real-time monitor the complex situations around the vehicle and provide early warnings and braking for potential collision risks in complex road traffic environments. For example, the AEB function supports warnings and braking for forward stationary and crossing vehicle targets at risk of collision, while the LDW, LDP, and ELK functions can alert or correct unintentional lane departures to minimize the risk of the vehicle deviating from the lane.

High plateau environments generally have what kind of impact on vehicles? （注：您的句子在中文中似乎不完整。如果您想问的是“高原环境对车辆有哪些影响？”那么翻译如下：） High plateau environments generally have what effects on vehicles?

The main characteristics of high-altitude environments are low temperatures and low air pressure. The low temperature primarily affects the range, charging, and discharging performance of pure electric vehicles; while low air pressure poses challenges to the sealing of battery packs and the adjustment performance of air suspensions. But rest assured, whether it's the Xiaomi SU7 Ultra or the Xiaomi SU7, we have conducted thorough road tests and durability tests before the vehicles are launched to ensure their performance.All functions can operate normally under extreme conditions (such as extreme heat, extreme cold, or high altitude).。

The thermal management system of the Xiaomi SU7 Ultra is capable of staged heating for three heat sources, ensuring optimal charging and discharging performance of the battery in low-temperature conditions and effectively enhancing the vehicle's driving range in cold climates, while maintaining a comfortable in-car environment temperature. Additionally, the battery pack of the Xiaomi SU7 Ultra has been specially designed for sealing under low air pressure conditions and has undergone extensive testing to ensure its sealing performance in high-altitude regions. Furthermore, the air suspension system standard on the Xiaomi SU7 Ultra operates in a closed system, with both inflation and deflation occurring within enclosed piping, thus unaffected by external air pressure. Consequently, it maintains the same lift and lower speeds in plateau areas as it does in plain regions.
