XPeng’s X9 EREV model features advanced tech and collaborations, emphasizing range, comfort, and urban maneuverability.
On Nov. 6, ahead of a technical briefing, XPeng disclosed the supply-chain configuration of its X9 Super Extended-Range model (X9 EREV), covering range-extender, chassis, safety and intelligent systems.
More than 90% of components are sourced from established domestic and international suppliers, including Huawei, Bosch, ZF and Adient.
In the powertrain, the X9 EREV becomes the first model globally to feature Huawei’s DriveONE high-voltage range-extender generation system, designed to deliver “imperceptible range-extension.” Calibration focuses on minimizing start-stop and operating noise, which the company says can be lowered to levels comparable to a library.
The range-extender, supplied by Dongan, is a third-generation unit with a claimed WLTC fuel consumption of 0.15 L/100 km. Start-up noise is said to increase by less than 1 dB. XPeng and Huawei co-developed the system’s algorithms and vibration control to enhance driving range and NVH performance.
The X9 EREV’s control system uses UAES’s next-generation PFI platform, built on the new MG1 torque architecture and intelligent combustion algorithms to improve throttle response and noise management.
Chassis development involved multiple partners. ZF provides rear-wheel steering that reduces the turning radius to 5.4 m, aiming to ease maneuverability of large MPVs in urban environments.
Bosch contributes its latest IPB 2.0 intelligent integrated braking system to support energy recuperation, extend range and enable advanced driver assistance. Nexteer supplies the steering system, while XPeng oversees overall chassis tuning.
In manufacturing, Guangdong Hongtu performs 12,000-ton integrated rear-body die-casting for the X9 EREV. Brake calipers are custom-made by Jingxi Zhixing, emphasizing strength and heat dissipation.
Cabin comfort is another highlight. Adient and XPeng jointly developed second-row zero-gravity seats, with anti-submarine airbags included as standard for the first time. For display, Foryou and XPeng developed a HUD system with a large virtual-image layout to improve readability under daylight and rain-night conditions.
For safety, Autoliv supplies steering wheels and multiple airbags, including surround and wide-angle belt restraints. In NVH, XPeng collaborates with Goertek, leveraging acoustic algorithms and multi-sensor solutions to reduce road and wind noise.
Across the supply chain, range-extension, power control and chassis systems are supported by Huawei, Bosch and ZF, giving the X9 EREV a more mainstream technological path. XPeng aims to balance range, urban maneuverability and quietness in the large seven-seater segment.
Pricing has not been released. Given the X9 BEV’s starting price of RMB 359,800 ($50,372), the EREV variant is expected to come in lower.
The XPeng X9 EREV model will make its official debut at 7 p.m. today, when more detailed technical specifications will be revealed.
