car safety has always been one of the most important factors for consumers when buying a car. not long ago, chery group's high-end new energy series star era medium and large pure electric sedan, the 2025 star era es, completed an ultra-high-speed 120km/h three-car clamping collision test in tianjin, refreshing people's perception of car safety with its unimaginable hard-core performance.
an extreme challenge that exceeds the national standard by 6.36 times
this test was led by the china automotive technology and research center (catarc) to simulate a real-life collision scenario. a star era es was used as the test vehicle, and two bullet cars hit each side at a speed of 60 km/h, simulating the dangerous situation of being sandwiched by vehicles on both sides of the lane when turning. the test speed far exceeded the 50 km/h collision speed of the 2021 version of c-ncap side collision, and the impact energy was equivalent to the energy of 117gtnt explosion. the test difficulty exceeded the national standard by 6.36 times.
security strength, all-round protection
after the collision, the star era es showed excellent safety performance:
occupant protection: the side airbags, side curtain airbags and distal airbags were detonated in a timely manner, the seat belts were pre-tightened in a timely manner, and there was no obvious deformation of the seat mounting points and the frame, effectively controlling the dummy's injury value.
body structure: the passenger compartment is intact, and there is no structural failure in the a, b and c pillars, providing sufficient living space for the occupants.
battery safety: the high-voltage system automatically cuts off the power, and the battery pack does not shift, leak, smoke, catch fire, or explode, achieving the ultimate in safety quality.
accident rescue: the hazard lights are turned on in time, the e-call emergency rescue function is automatically triggered, and the doors are automatically unlocked, preserving a life-saving passage for rescuing the occupants in the car.
safety "fast" concept, creating hard-core strength
the reason why star era es has such outstanding safety performance is inseparable from its "safety fast" development concept, which aims to achieve the safety goals of "0 damage, 0 spontaneous combustion, 0 leakage, 0 intrusion, 0 loss of control, 0 gradual freezing, and 0 isolated islands".
body structure: it adopts a cage-type space capsule 2.0 high-performance body, with high-strength steel accounting for up to 88%, and torsional rigidity increased to 46000n·m/deg, providing solid protection for the occupants.
restraint system: equipped with active motor pre-tensioned seat belts, 7 airbags as standard, and the longest side air curtain in the industry, providing all-round protection for occupants.
battery safety: it has a 1+8+1 super battery safety protection system, uses high-strength composite materials and ultra-high-strength steel, and is equipped with explosion-proof valves, mica boards, high-temperature resistant insulation materials, etc., to effectively prevent thermal runaway and fire and explosion.
electrical safety technology verification: obtained the "nesta six-dimensional electrical safety" certification of the china automotive technology and research center's new energy vehicle electrical safety technology verification system, covering multiple dimensions such as charging safety, electromagnetic safety, functional safety, high-voltage safety, battery safety, and fire safety.
conclusion:
the success of the star era es not only demonstrates chery group's hard-core strength in the field of high-end new energy, but also sets a new benchmark for the safety of new energy vehicles in china. i believe that in the future, the star era es will bring more users a safe and comfortable driving experience with its outstanding safety performance.
