At the BYD Fan Carnival held on September 13, Li Yunfei, General Manager of the Brand and Public Relations Department at Byd Company Limited, stated that the company insists on conducting full-dimensional testing to standards that exceed national requirements, with validation covering complete vehicles, subsystems, and components. He emphasized that vehicles are put through extreme global conditions, from the scorching heat of the Middle East and the high humidity of South America to the freezing temperatures of the Arctic Circle, to ensure they are truly battle-ready.

As a global leader in new energy vehicles, the pursuit of safety and quality is deeply embedded in BYD's corporate DNA. For instance, the Yangwang U7 recently completed a 30,000-kilometer endurance challenge in 8 days, 19 hours, and 58 minutes, setting a new world record. Notably, the test vehicle was not specially prepared; it was randomly selected from showroom inventory with no modifications. In Nanning, under 36°C heat and 80% humidity, this production car completed over 350 rapid charge-discharge cycles—simulating 6-7 years of typical user charging compressed into nine days—while maintaining 98.7% battery capacity. This achievement demonstrates that a truly reliable vehicle is unafraid of the most extreme validation.

The Yangwang U7's extreme test is just one example. Across the entire BYD portfolio—from Yangwang and Denza to Fangchengbao and the core BYD brand—safety and quality are seamlessly integrated. Authoritative results provide the strongest proof: the Denza N9 achieved top scores in all C-IASI tests, becoming the first vehicle in nine years to earn the highest ratings in five categories; the Bao 8 received a five-star C-NCAP safety certification from CATARC, the first hybrid body-on-frame vehicle in China to do so; the Han L passed CATARC's electrical safety evaluation with high marks, also earning a five-star certification; and the Seagull 07 EV secured the highest safety ratings in Europe, China, and Australia in 2025, underscoring its globally consistent high safety standards.

More demanding than laboratory tests are the challenges of the real world, where BYD's safety quality has been verified through actual incidents. A Yuan PLUS in Israel survived a missile explosion at close range, with surrounding vehicles destroyed, yet its structure and battery remained intact, and all five occupants survived. In another case, a Tang SUV was struck by a 100-ton truck on the side and fell down a slope, but the passenger compartment remained free of significant intrusion, all airbags deployed, the battery did not catch fire, and the four occupants sustained only minor injuries. Such incidents have earned BYD the nickname "Highway Tank," a grassroots recognition of its safety record.

From its very first day, BYD has elevated safety and quality to a core corporate strategy, integrating it throughout vehicle definition, development, validation, and production. Core technologies such as the Blade Battery, e⁴ Platform, and DiPilot are all built around safety at their foundational level, with every technology undergoing rigorous validation before deployment. On the hardware front, BYD operates over a dozen testing bases in Shenzhen, Xi'an, and beyond, supported by more than 300 specialized laboratories. Li Yunfei noted that the Nanning proving ground is expected to be fully completed by 2027, with its high-speed ring road and durability tracks already in use, complementing existing facilities in Shenzhen and Xi'an as well as extreme-weather sites in Yakeshi, Turpan, and Golmud.

In terms of standards, BYD adheres to a principle of "150-point corporate standards," going 50% beyond industry requirements as a form of self-imposed "extra credit." Reliability testing begins at a minimum of 60,000 kilometers per vehicle, double the industry standard, while complete vehicle durability validation starts at one million kilometers, with the Yangwang U7 reaching an extraordinary 10.49 million kilometers. Additionally, BYD conducts its own "edge-case" tests in areas where national standards are absent, such as slippery parking garage floors and vehicle floatation in water, with hundreds of tests on the Blade Battery alone. These seemingly meticulous investments reflect BYD's unwavering commitment—quality leaves no room for shortcuts, and safety tolerates no luck.

This rigorous quality control ultimately translates into market confidence backed by real investment. To date, BYD's cumulative sales have surpassed 17.8 million vehicles, with nearly a quarter of annual new car sales coming from repeat or upgrade purchases by existing owners. For millions of users, choosing a BYD means choosing a comprehensive safety net that spans from the laboratory to the real world—a layered defense that reinforces why BYD earns trust with every drive.
