The Buick Envision may be built in China but it is still held up to the highest of quality standards and safety is at the forefront of their mind when it comes to the structural design. More than 75% of the body is made up of high-strength and ultra-high-strength steel held together with advanced laser brazing technology for a robust structure.
The blue highlighted “a” and “b” pillars were made to have a yield strength of 950MPa and a tensile strength of 1300MPa. Ultra-high-strength steel was used in the lower half of the a-pillar, what seems to be the interior of the b-pillar, and in the engine area. These plates have highest yield strength in the vehicle at 420MPa-1200MPa and a tensile strength of 780MPa-1500MPa.
Most of the remaining body structure is made from high-strength steel with yield strength of 210MPa-340MPaa and tensile strength from 340MPa-590MPa. If a crash test video of the Buick Envision is ever released, we could see minimal cabin intrusion with the ultra-high-strength steel supports in the bumper.
On top of a sturdy body, Buick has also added two front passenger air bags and two long side airbags spanning the length of the interior passenger area for full passenger protection.
We’ll know for sure if the Envision can live up to the standards set by the North America built Buicks when the Insurance Institute for Highway Safety (IIHS) report comes out.
