Xiaomi New SU7 Built-in Roll Cage: Functions & 2200MPa Ultra-Strong Steel Structure
What is the function of the built-in roll cage in the new-generation Xiaomi SU7?
Across all variants of the new-generation Xiaomi SU7, hot-forming gas expansion tubes made of 2200MPa Xiaomi ultra-high-strength steel are embedded between the A-pillars and C-pillars on both the left and right sides. Each side measures 2.56 meters in length, forming a built-in roll cage structure.
In extreme scenarios such as rear-end collisions with trucks and vehicle rollovers, this structure effectively reduces the risk of passenger compartment deformation and enhances occupant protection performance.
