Lingxi Drive Mastery, Craftsmanship Empowers: The Power Core Secret of the Huajing S

Huajing S Makes a Powerful Debut

On May 8, SGMW's all‑new flagship large six‑seat SUV, the Huajing S, was officially launched. Powered by SGMW's self‑developed all‑new generation Lingxi Drive 3.0 hybrid system, it serves as the core pillar for the model's performance and experience upgrades, and represents a major achievement in the brand's commitment to "precision R&D breakthroughs." With its solid capabilities, it delivers on the promises of "ultra‑powerful, ultra‑economical, ultra‑smooth, and ultra‑reliable."

The Lingxi Drive 3.0 was first mass‑produced and launched on the Xingguang 730, and has since earned two prestigious industry honours from CATARC: "High‑Quality Hybrid" and the "2025 China Heart Top Ten Engines and Hybrid Systems." Its core component, the electromagnetic clutch, was recognised as an "internationally advanced" technological achievement, earning broad market recognition for its stable and reliable performance.

Lingxi Drive 3.0 High‑Power Version Certificate

The Huajing S is equipped with the Lingxi Drive 3.0 high‑power advanced version, featuring a 1.5T DHE (Dedicated Hybrid Engine) + ten‑in‑one DHT (Dedicated Hybrid Transmission) architecture, delivering a comprehensive leap in power performance. It has also received the CATARC "High‑Quality Hybrid" authoritative certification.

The engine optimises combustion efficiency through a high EGR (Exhaust Gas Recirculation) rate and low‑friction technology, achieving a production thermal efficiency of 43.2% with broader high‑efficiency operating range coverage.

High‑Integration Ten‑in‑One Electric Drive

The fourth‑generation ten‑in‑one DHT features an oil‑cooled flat‑wire high‑speed motor with ultra‑thin silicon steel sheets, achieving a peak efficiency of 97.5%. Combined with a full‑domain ring‑type oil‑cooling structure, rated power has been increased by 30%. The electronic control adopts a modular power brick design with next‑generation power chips and advanced laser welding technology, delivering a 20% increase in power density and a 15% reduction in stray inductance for more stable system control. Its operating temperature tolerance reaches 175°C, surpassing the industry mainstream of 150°C, with lower current loss. It has also passed ASIL automotive functional safety and ASPICE in‑vehicle software standards certifications. Equipped with the industry‑exclusive electromagnetic clutch, it achieves an ultra‑fast response time as low as 0.1 seconds, enabling smooth and seamless power transitions. The gear shaft features a high‑contact‑ratio compact design, fully adaptable to diverse driving conditions, with significantly improved NVH performance. The entire powertrain architecture integrates multiple cutting‑edge technologies, achieving dual breakthroughs in performance and space, setting a high‑value benchmark for driving experience.

With "precision breakthroughs" as the core direction, the R&D team established a multidisciplinary task force to complete the full‑cycle R&D process from technical validation to mass production.

Technical Solution Review

The team underwent multiple rounds of simulation iteration and bench calibration, breaking through key engine technologies including high‑tumble‑ratio intake and high‑pressure side‑mounted direct injection to improve combustion efficiency. They simultaneously conquered critical technologies such as precise EGR control and integrated thermal management, achieving faster warm‑up and lower emissions through systematic optimisation and precise control.

The team focused on developing the new‑generation multi‑in‑one integrated DHT. After multiple rounds of solution selection and refinement, they finalised a stacked design for the power module and charge/discharge module. Through a series of initiatives including integrated packaging, customised connectors, and housing topology optimisation, they significantly reduced installation space, improved system space utilisation by over 10%, and reduced housing weight by 8.5%. Ultimately, they achieved precise adaptation of the DHT system to the vehicle and piping, optimised energy transmission pathways, and comprehensively enhanced product competitiveness.

Engineers at Work

SGMW, in collaboration with Saike, innovatively developed an island‑style production line layout, laying a solid foundation for the assembly quality and production consistency of the ten‑in‑one DHT. The R&D and production teams formed a spherical organisation to manage key assembly parameters throughout the entire process, achieving real‑time alignment between design and mass‑production processes, significantly improving technology implementation efficiency and product consistency.

Joint Review by the Spherical Organisation

The production line employs full‑process intelligent control, achieving 100% automated assembly for critical processes and end‑to‑end quality traceability, providing a solid foundation for large‑scale, high‑quality product delivery.
