How does the YU7 keep the A-pillar and passenger compartment undeformed during severe frontal and side collisions?
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 lateral thrust for the vehicle, avoiding a "hard clash" with obstacles. To prevent components like wheels from intruding into the passenger compartment, the YU7 uses wheel linkage design to make the wheels rotate and eject in a preset direction under extreme collision energy, ensuring greater safety for passengers' legs.
In addition, the Xiaomi YU7 reinforces the structural strength of key areas in the passenger compartment: it applies a 2200MPa "embedded roll cage," combined with multi-level high-strength materials such as 2000MPa and 1500MPa, to reinforce the passenger compartment step by step.
Final performance: The passenger compartment structure remained intact, the A-pillar showed no deformation, airbags deployed normally, providing ample protection for occupants. Both the driver-side and passenger-side 25% small overlap frontal crashes received the highest G rating.
