On December 2, 2025, Xpeng Auto and Huawei jointly held a media technology sharing session on next-generation range extenders at Huawei's Songshan Lake Campus, announcing the global debut of the Huawei DriveONE full-stack, highly integrated, high-voltage oil-cooled generator in the Xpeng X9 Super Range Extender. This collaboration marks a new dimension in range extender technology, moving from "solving range anxiety" to "pursuing the ultimate experience," redefining the technical standards for "next-generation range extenders."
As the first model equipped with Huawei DriveONE's next-generation range extender generator, the Xpeng X9 Super Range Extender showcases several groundbreaking technologies:
Extremely Long Range: The CLTC combined range reaches 1602km, and the CLTC pure electric range is 452km, completely eliminating range anxiety;
High Efficiency: Equipped with a 63.3 kWh battery and a 60L fuel tank, it achieves a class-leading combined fuel consumption of 2.53L/100km (the lowest fuel-electric equivalent in its class);
Quiet Experience: The range extender's intervention noise is ≤0.5dB(A), and start-stop vibration is reduced by 60% through active cylinder deactivation technology;
Powerful Performance: Equipped with a 1.5T range extender, the rear-mounted single motor has a maximum power of 210kW, and the 0-100km/h acceleration time is 8 seconds.
The Huawei DriveONE full-stack highly integrated high-voltage oil-cooled generator is the core technology of the Xpeng Kunpeng range extender generator. The core components of the super range extender technology possess the following innovative features:
Strong Performance Breakthrough
Ultra-high power density: Continuous power generation density reaches 1.88kW/kg, leading the industry by 40%;
High-efficiency power generation capacity: Operating power generation efficiency ≥92%, fuel power generation efficiency 3.6kWh/L;
Stable output: Supports a maximum power generation of 85kW and a continuous power generation of 75kW, ensuring no battery depletion during high-speed cruising at 150km/h.
Quiet Experience Upgrade
Precise active cylinder deactivation technology: Start-stop noise and vibration reduced by over 60%;
ENC active noise reduction: Range extender intervention noise ≤0.5dB(A), cabin noise 6dB lower than the industry average;
Compact design: Generator Y-axis dimension ≤230mm, achieving high integration without encroaching on cabin space.
Xpeng and Huawei This collaboration addresses several pain points of traditional range-extender systems:
Space vs. Performance Conflict: A highly integrated design combines 82 components, increasing the overall internal X-axis length by 23mm;
Range vs. Efficiency Balance: Achieving an ultra-long combined range of 1602km while maintaining high energy efficiency;
Quietness vs. Power: Achieving NVH performance comparable to pure electric vehicles while maintaining strong performance.
Industry experts believe this collaboration marks a shift in range-extender technology from a "supplementary solution" to a "user experience-first" systems engineering approach. Through comprehensive improvements in power density, power generation efficiency, and NVH performance, it essentially redefines the value of range-extender technology.
The Xpeng X9 Super Range Extender is positioned as a range-extended AI-powered large seven-seater vehicle targeting global families. Currently, it is available in two versions:
2026 Range Extender 1602 Ultra: Starting at RMB 329,800
High-spec version: RMB 370,000
Pre-sales for this model began in November 2025. It is expected to set a new technological benchmark in the range-extended market thanks to its core technological advantages of a "super-fast charging large battery + large fuel tank" combination and the Huawei DriveONE generator.
