Recently, ZEEKR cooperated with the TOP Safety Challenge Platform of China Automotive Center to successfully complete ZEEKR 009"Double A-pillar"Challenge the dynamic top pressure of the 30-ton concrete mixer truck, and once again defend the industry reputation of "the world's safest MPV".
At the intersection, a large concrete mixer truck with a total weight of 30 tons turned right at a speed of 20 kilometers per hour to drive on a unilateral bridge, and turned to the left side of the roof of the main driver of ZEEKR 009 to form a collision and crushing, and the "double A-pillar" bore the brunt.
The test results show that after suffering from the overload impact of the mixer tank, the front windshield of ZEEKR 009 is only broken at the angle, the body structure is intact, the ABC column of the vehicle does not appear obvious bending, denting or rupture, etc., the doors and tailgates on both sides can be opened and closed normally, the chassis air spring rebounds normally, the erosion of the passenger compartment is not obvious, the head, neck, spine, chest, hips and legs of the dummy in the car are excellent, the vehicle can drive normally, and the safety of the three electric vehicles is normal.
The 30-ton concrete mixer truck overturned and pressed the roof, and the body of ZEEKR 009 was intact.
The front windshield is cracked only at the corners.
Tough "top pressure killer" super national standard 1Double top compressive strength
As we all know, due to the large mass and high center of gravity of large trucks and concrete mixer trucks, once they roll over, they are easy to form a rolling over the roof of passenger cars, becoming a veritable "top pressure killer", and top pressure is often the weak link in the safety design of many models.
As the world's first native pure electric luxury MPV, ZEEKR 009 completely subverts the safety defects of traditional MPVs, with a maximum top pressure resistance of 128KN and a roof of up to 13 tons. In order to verify the safety performance of ZEEKR 009, this test changed the static pressure condition of the national standard to the dynamic working condition, which greatly increased the difficulty. In order to further increase the difficulty, the 30-ton concrete mixer truck completed the rollover by climbing the slope on a unilateral bridge, and the center of gravity was higher than that of flat driving, and the collision energy was greater. In the comparative test before the test, an old scooter was crushed by a mixer truck and instantly became a "waste product".
The old scooter became a "scrap" in seconds
The contact area between the tank and the body is only 0025 sq.m.
Double A-pillarHardcoreEnergy absorptionForge a fortress of safety
ZEEKR's outstanding security performance is no accident. Different from most MPVs that only use a single A-pillar, ZEEKR 009, known as the "Highway T-Krypton", introduces the hidden double A-pillar into the MPV model, creating a precedent in the industry.
The A-pillar of ZEEKR 009 is made of 2000MPa ultra-high-strength hot-stamping steel, and the yield strength is 2 times that of steel used for nuclear submarines and 8 times that of ordinary technology, and CBS composite filling technology is used in the A-pillar. The stable triangular design, four-layer reinforced structure and 480mm back bearing point make ZEEKR 009 have a wider buffer energy absorption area, which can effectively absorb the frontal and longitudinal impact of the A-pillar and reduce the injury to the front seat passengers. Being able to "withstand" the heavy pressure is not only the safety foundation cast by ZEEKR's "double A pillar", but also the proof of the strength of the hardcore to protect the safety of passengers.
Hidden double A-pillar, up and down can be topped, front and back can be carried.
At the second scene, Professor Zhang Jinchang, director of the Automotive Crash Laboratory of the State Key Laboratory of Automotive Safety and Energy Conservation of Tsinghua University, and Yang Heping, a senior safety expert of ZEEKR, witnessed the safety test results of ZEEKR 009 under real top pressure conditions.
The scientific design method of the triangular double A pillar has played an important role in this dynamic top pressure test", "In terms of design, materials, technology, etc., the body of ZEEKR 009 is the best, and it deserves it!".At the scene, Professor Zhang Jinchang Zhang spoke highly of the safety capabilities of ZEEKR 009. "In addition to ensuring the safety of passengers, the safety of the three electric vehicles is also equally important, during the collision, it is not only necessary to protect the all-round safety of passengers, but also to ensure the normal operation of the three electric vehicles," added Yang Heping, a senior safety expert of ZEEKR.

In this live broadcast challenge, ZEEKR once again led the industry's test standards with actions, and built a well-deserved "safety fortress" with the most demanding crash test.
The safest in the worldmpvVerify the "Highway Tankrypton" againNationwide word-of-mouth
For a long time, the safety performance of ZEEKR 009 has been tested by "actual combat" for a long time. For example, ZEEKR 009 once rear-ended a semi-trailer, but the A-pillar did not bend, but tore out a hole in the thick steel plate at the tail of the semi-trailer. Coincidentally, ZEEKR 009 was rear-ended by a double-decker bus and hit the front SUV, only because the front cabin was deformed to a certain extent and the rear window glass was broken, and the frame structure remained highly intact. At the same time, the vehicle can even maintain normal driving, indicating that the three electric and transmission systems have not been damaged.

The double-decker bus rear-ended and hit the SUV in front of it, but it can still drive normally.
Don't be afraid of collisions, don't **" excellent safety genes, derived from the "extreme krypton safety" vehicle 720 ° all-round safety armor protection. In addition to the hard-core "double A-pillar", in terms of battery safety protection, ZEEKR 009 pioneered the "ten-square" battery anti-collision structure, using the industry's thickest aluminum side anti-collision beam, which cushions the battery layer by layer when it is impacted, and relies on NTP non-thermal spread technology, which can effectively prevent battery combustion. The cumulative delivery of ZEEKR products has exceeded 180,000 units, and it still holds the record of "the world's only zero spontaneous combustion", which is the best proof of ZEEKR safety.
"Ten-square grid" battery anti-collision structure.
At the rear end of the weakest traditional MPV, ZEEKR 009 has also successfully built a one-piece die-casting rear aluminum body through the industry's largest 7,200-ton giant die-casting machine, reducing nearly 800 welding points, reducing deformation by 16%, increasing bending stiffness by 11%, and torsional stiffness by 95%, the rigidity of the vehicle reaches more than three times that of the traditional luxury MPV, effectively protecting the rear safety. Not only that, the one-piece die-cast rear aluminum body also sets up a two-stage detachable buffer structure through an innovative four-stage collision zoning strategy, which can greatly reduce the maintenance cost of the vehicle after a collision.
The world's largest mass-produced one-piece die-cast rear aluminum body.
Hardcore guards safety, strength is not afraid of pressure!In the face of all kinds of difficult tests, ZEEKR 009 writes safety into the genes, not only to achieve the all-round protection of 720-degree safety armor, but also to establish internal standards in safety conditions that are not achieved by global standards such as frontal center pillar collision and 15 azimuth side impact tests.
Defining "Highway Tamprypton" with "Extreme Krypton Safety" not only brings users "safety for all six seats", but also raises the safety standard of pure electric luxury MPV to a new height!
