On December 2, 2025, XPENG-W (09868) and Huawei held a joint media technology briefing at Huawei’s Songshan Lake campus to introduce their next-generation range extender. The two companies announced that the XPENG X9 Super Range Edition will be the first globally to feature Huawei’s DriveONE fully integrated high-voltage oil-cooled generator.

As the core component of XPENG’s Kunpeng Super Range technology, this generator sets a new industry benchmark with its industry-leading 1.88kW/kg continuous power density, ≥92% operational efficiency, and seamless range-extending experience.

The XPENG X9 Super Range Edition redefines next-gen extended-range EVs with its "ultra-fast charging + large battery + large fuel tank" configuration. Designed as a global family-oriented AI-powered seven-seater, it demands exceptional performance in its powertrain: long pure-electric range, rapid charging, strong power retention at low battery levels, low energy consumption, minimal noise, and high space efficiency—all while maintaining cabin comfort.

However, traditional range-extender systems initially fell short of these requirements. Existing solutions struggled with inefficient energy replenishment, limited pure-electric range, inadequate power generation, and NVH (noise, vibration, harshness) performance inferior to pure EVs. No off-the-shelf generator could meet the stringent demands of high-voltage platforms, ultra-high integration, peak efficiency, and silent operation.

To overcome these challenges, XPENG and Huawei co-developed the DriveONE fully integrated high-voltage oil-cooled generator. Customized for XPENG’s high-voltage pure-electric platform, this "powerhouse" delivers industry-leading power density and performance, enabling the X9 Super Range Edition to realize its vision of next-gen extended-range mobility.

**Power Meets Silence: Huawei DriveONE Generator’s Engineering Breakthroughs** The DriveONE generator excels in both power and quietness. Its "strength" lies in its unmatched power density, robust power generation, and energy retention. Utilizing multi-segment tooth-spray cooling technology, it achieves a compact, lightweight design with a continuous power density of 1.88kW/kg—40% above industry standards. Paired with a 1.5T range extender, it delivers 85kW max power output, ensuring ample energy even under high-load conditions like highway driving or climbing.

On the "silence" front, XPENG and Huawei’s precision active cylinder deactivation technology reduces start-stop noise and vibration by over 60%, while advanced software algorithms ensure smooth, stable operation across driving scenarios—approaching pure-EV quietness.

**Four Key R&D Challenges Conquered** 1. **Space Optimization**: The X9’s compact front layout required ultra-high integration without compromising cabin space. By minimizing the generator’s Y-axis dimension to ≤230mm and leveraging XPENG’s front-megacasting (82 parts consolidated), the team achieved a 23mm increase in X-axis space utilization—an industry breakthrough.

2. **Efficiency**: To support the X9’s record 1,602km range (longest among global seven-seaters), the DriveONE generator achieves ≥92% operational efficiency and 3.6kWh/L fuel-to-electricity conversion. Combined with XPENG’s 16.5kWh/100km ultra-low energy consumption and 2.53L/100km hybrid-equivalent fuel economy, the X9 sets new benchmarks for efficiency.

3. **Power Consistency**: With 75kW sustained power output and XPENG’s 93.5%-efficient 800V SiC coaxial e-drive, the X9 maintains 150km/h cruising without power loss. Even at 8% SOC, it delivers class-leading power retention, eliminating range anxiety in high-demand scenarios.

4. **NVH Excellence**: Through active cylinder deactivation, joint GCU calibration, and structural optimizations including ENC active noise cancellation, the X9 achieves ≤0.5dB(A) range-extender noise—rivaling pure-EV tranquility.

**A New Era for Extended-Range EVs** The XPENG X9 Super Range Edition, powered by Huawei’s DriveONE generator, marks the arrival of truly seamless "dual-energy" mobility—offering extended range, rapid refueling/recharging, robust performance, and serene comfort. This collaboration not only sets a new standard for range-extender technology but also accelerates the industry’s shift toward intelligent, sustainable transportation.
