The China Insurance Automotive Safety Index (C-IASI) is a vehicle safety evaluation system conducted under the guidance of the Insurance Association of China. From the perspectives of insurance and consumers, it performs real-world crash tests across five dimensions: occupant safety, pedestrian safety, vehicle assist safety, new energy vehicle-specific tests, and crashworthiness with repair economy.
Both C-IASI and C-NCAP are professional automotive safety evaluation systems in China. They condu…
In the C-IASI crash test, the "frontal and side collision" actually refers to a 25% small overlap frontal crash, primarily simulating accident scenarios where vehicles collide with a small overlap area.
The reason the A-pillar and passenger compartment remain undeformed in this test is that the Xiaomi YU7 adopts a strategy of "yielding to overcome rigidity" through "body sliding + wheel rotation + body reinforcement." It disperses collision forces through multiple load paths while generating lat…
The 2200MPa ultra-high-strength steel is applied in 10 locations across the vehicle, covering two core areas:
Four Door Anti-Collision Beams (4 locations): Installed inside the four doors, serving as the first line of defense in side collisions. Compared to 1500MPa hot-formed steel, its tensile strength is increased by 40% and yield strength by 24%;
Embedded Roll Cage (6 locations): The A-pillars and B-pillars embed 2200MPa Xiaomi ultra-high-strength steel gas-expansion tubes, forming an "embedd…
The airbag that deploys for the front passenger is the uniquely shaped front passenger airbag, which comes standard on all Xiaomi YU7 models.
Standard airbags expand into a circular or oval "air cushion." The core difference of the uniquely shaped airbag lies in its side wings—they are significantly larger, expanding like a "wrapping protective cover" that can "cradle" the head, reducing the risk of lateral sliding out. This is a specialized optimization for the head movement trajectory of the f…
The new energy vehicle-specific tests include battery underbody impact and whole-vehicle scraping tests. The YU7 achieved the highest G rating thanks to these three lines of defense:
First Line: 1500MPa Anti-Scrape Bottom Beam. This beam is located in front of the battery pack and sits lower off the ground than the battery pack itself. Rocks and obstacles on the road hit the beam first, being pushed aside or deflected, so the battery pack does not directly bear the impact. Its role is to "clear …
