On May 16, the 2026 China Tarim Basin International Rally officially kicked off at Tianshan Grand Canyon in Urumqi. Amid this ultimate test of endurance, the Aerospace Jiye (Extreme Wild) racing car, powered by Yuchai's specially tuned 530-horsepower S07 racing engine, made a strong debut. It tackles the western frontier with high-performance domestic power, marking a new milestone for China's commercial vehicle power to enter top-tier off-road competitions.
Certified by the FIA as Asia's premier Grade A long-distance off-road rally, the Tarim Rally has long been recognized as the ultimate proving ground to test vehicle performance and demonstrate brand strength. This year's event covers a total distance of 7,500 kilometers, including 3,400 kilometers of special stages-setting a new record for the longest course in the rally's history. Extreme heat, sandstorms, and continuous high-load operation place extremely rigorous demands on the engine's power, reliability, and durability.
The specially tuned 530-horsepower Yuchai S07 racing engine is a "Chinese Core" custom-built for extreme racing conditions. The mass-produced S07 engine is already celebrated for its robust power, high reliability, and low fuel consumption. Following exclusive in-depth tuning, its 6.89-liter displacement delivers an impressive 530 horsepower and a torque of over 1,800 N·m. Maximum torque is available at low speeds, making it perfectly suited for complex scenarios such as desert launches, Gobi acceleration, and steep slope climbing.
To adapt to Xinjiang's harsh environment, Yuchai's technical team has made targeted optimizations to the heat dissipation, air intake, and fuel supply systems. These enhancements ensure the engine maintains stable power output and consistent performance even under extreme operating conditions, providing the racing car with strong, reliable power support in all weather, terrain, and working conditions.
The strategic collaboration between Aerospace Jiye (Extreme Wild) and Yuchai achieves in-depth integration of professional racing tuning and top-tier power systems. It also breaks the long-standing dominance of overseas power units in top-level off-road events, further proving that China's commercial vehicle power is not only capable of daily operations but also possesses the strength to compete at the world-class level.
Participating in the Tarim Rally is not only an extreme validation of Yuchai's independent R&D capabilities but also a catalyst for its technological breakthroughs in high-performance power. Moving forward, Yuchai will continue to take innovation as its driving force and quality as its foundation, enabling Chinese power to travel further and continuously unleash the vitality of Chinese manufacturing on the global stage.
