China Fortune Network News - On December 18, the rollout ceremony for BYD's 15-millionth new energy vehicle (NEV) was grandly held at its Jinan plant, marking a brand-new stage in the development of China's NEV industry. The model rolled off the line was the Tengshi (Denza) N8L, launched this year. Coincidentally, this vehicle was also the 15,000th Tengshi N8L produced. This dual milestone not only highlights BYD's robust production strength but also reflects the maturity and perfection of China's NEV supply chain. In this industrial miracle, fasteners—known as the "rice of industry"—play an indispensable and critical role.

It took BYD 17 years to go from 0 to 15 million vehicles, yet only 13 months to surge from 10 million to 15 million. This striking contrast in timelines not only sets a new "acceleration" record for China's NEV sector but also validates the highly efficient synergy of the national supply chain. Throughout the entire vehicle manufacturing process, although small in size, fasteners run through core links such as body assembly, powertrain fixation, and electronic component integration. Their quality and performance directly impact vehicle safety, reliability, and production efficiency. BYD's ability to achieve such rapid capacity ramp-up relies heavily on the precise supporting capabilities of upstream fastener enterprises. From the large-scale supply of standardized fasteners to the technical adaptation of customized high-end ones, a highly efficient collaborative ecosystem has been formed.

Strong market performance is a direct reflection of industrial prowess. From January to November this year, BYD achieved cumulative sales of 4.182 million vehicles, a year-on-year increase of 11.3%. Notably, overseas sales exceeded 917,000 units, far surpassing the total for the entire year of 2024, with its footprint covering over 110 countries and regions. The rapid expansion into global markets imposes higher requirements on vehicle adaptability. Especially under varying climatic conditions and road environments, fasteners face severe tests regarding corrosion resistance, vibration resistance, and high-temperature tolerance. BYD's solid foothold in the global market benefits not only from its own technological advantages but also from the stable performance of supporting fasteners in extreme environments, providing fundamental assurance for global vehicle adaptation.

The root of BYD's rapid growth lies in its long-term adherence to the strategies of "Technology is King" and "New Energy Vehicles." In the first three quarters of this year, BYD's R&D investment reached 43.75 billion yuan, a 31% year-on-year increase, with cumulative R&D spending exceeding 220 billion yuan. This continuous technological breakthrough leads industrial transformation. Within BYD's rich "technology pool," innovative technologies like the "God's Eye" advanced driver-assistance system, Megawatt Flash Charging, Super e-Platform, Yi Sanfang (Tri-Motor), and Yi Sifang (Quad-Motor) have been successively implemented, offering systematic solutions to industry pain points such as safety, range, and handling. The application of these technologies relies entirely on the precise matching of customized fasteners. For instance, in the Yi Sifang system, the four-wheel independent drive and steering require a vast number of high-precision, high-strength fasteners to secure components, ensuring efficient and stable power transmission. Meanwhile, the integrated design of the Super e-Platform places higher demands on the miniaturization and lightweighting of fasteners, driving technological upgrades across the supporting industry.

As the core model of this milestone event, the Tengshi N8L achieved 15,000 units offline less than two months after its launch, marking a new phased achievement in BYD's high-end luxury brand strategy. The excellent performance of the Tengshi N8L is equally inseparable from the hardcore support of high-end fasteners. Thanks to the Yi Sanfang technology, the Tengshi N8L achieved the extreme safety performance of "no rollover in a 210 km/h fishhook test." Behind this achievement, beyond core technological breakthroughs, fasteners in key body connection areas play a vital role. These fasteners must maintain stable connection strength under extreme conditions to withstand immense lateral impact forces, with their material selection and manufacturing precision reaching top-tier industry levels.

In the realm of passive safety, the Tengshi N8L utilizes ultra-high-strength materials up to 2000 MPa in key body areas. Combined with hybrid CTB (Cell to Body) battery-body integration technology and 9 airbags, it constructs a comprehensive safety protection system. The assembly of a 2000 MPa high-strength body imposes extremely high requirements on the strength, toughness, and joining processes of fasteners. Ordinary fasteners struggle to meet the connection needs of ultra-high-strength steel. Through collaborative R&D with upstream fastener enterprises, BYD has adopted special alloy materials and precision manufacturing processes to create high-end fasteners adapted to 2000 MPa materials, ensuring the firmness and safety of body connections and fortifying the vehicle's passive safety foundation. Regarding handling performance, the Tengshi N8L boasts a minimum turning radius of only 4.58 meters. Its equipped DiSus-A (Yunnian-A) and road surface preview systems handle various complex road conditions with ease. This advantage is closely linked to the precise assembly of a large number of high-precision fasteners in the chassis system, ensuring the flexible operation and accurate coordination of suspension and steering components.

Furthermore, the Tengshi N8L offers a super-large interior space of 6.11 square meters and a flexible "4+N" seat layout, perfectly adapting to diverse family usage scenarios. In the design of movable components like seat adjustment mechanisms and interior storage units, the application of small precision fasteners is essential. These fasteners must not only ensure connection reliability but also possess low-noise and long-life characteristics to enhance the in-cabin experience. In terms of intelligence, the Tengshi N8L's AI agent integrates the DeepSeek large model, equipped with the God's Eye B - ADAS Laser Edition (DiPilot 300) and a car-home interconnection ecosystem. The installation and fixation of numerous electronic components and sensors require the support of micro-precision fasteners. These fasteners must feature anti-electromagnetic interference and anti-vibration loosening properties to ensure the stable operation of intelligent systems.

Currently, Tengshi's internationalization strategy is accelerating. It has successfully entered multiple Asian markets including Singapore, Thailand, and Malaysia, and has launched its brand in various regions across Europe and Latin America. In the first half of this year, the Tengshi D9 topped the luxury MPV sales charts in Indonesia, Thailand, Malaysia, and other countries. The global layout of the Tengshi brand is also driving the international development of the supporting fastener industry. Differences in automotive safety standards and environmental adaptability requirements across countries and regions compel upstream fastener enterprises to enhance their R&D capabilities, developing products that meet diverse global market demands and pushing China's fastener industry toward high-end and international transformation.

The achievement of BYD's 15-million-milestone is not just the success of a single enterprise, but a microcosm of the synergistic development of China's NEV supply chain. In this process, as a core supporting component, the technological upgrade and precise adaptation of fasteners provide fundamental guarantees for vehicle safety, performance, and efficiency. As the NEV industry accelerates towards high-end, intelligent, and global development, it will further drive demand growth in the high-end fastener market, compelling enterprises to increase R&D investment and improve product quality and technical levels. In the future, the collaborative innovation between NEV enterprises represented by BYD and upstream fastener companies will continuously promote the high-quality development of China's auto and equipment manufacturing industries, contributing Chinese strength to the global upgrade of the NEV sector.
