XPeng’s SEPA 2.0 architecture includes integrated front and rear aluminum die-casting technologies, a practice Tesla has been using since 2020 to manufacture unique vehicle underbody parts.
XPeng said the platform will be compatible with multiple vehicle platforms for wheelbases between 1,800mm and 3,200mm, and can support a variety of vehicle types, from hatchbacks and sedans to MPVs and pickup trucks.
The architecture also incorporates “Cell Integrated Body” technology, which integrates the battery pack into the car body to provide more cabin space, increase battery safety and improve driving performance with an improved center of gravity.
The smart manufacturing system will be built by 2025, the company said, adding that all manufacturing facilities will integrate SEPA 2.0 through technology upgrades.
“We anticipate that this evolutionary smart architecture will lead the development of smart EV technology for the next three years,” Xiaopeng said. “It will make rapid advances in technology available to our customers as standard, with faster software updates, impressive cost savings, and an enhanced product experience.”
XPeng also said the new architectural platform can help make its infotainment service, Xmart OS, available to all owners. Xmart OS is XPeng’s smart cockpit of multi-sensor hardware and software, and a key feature is voice assistant. The automaker said on Sunday that SEPA 2.0 shortens the research and development cycle of voice software by 50% and reduces the cost of voice assistant service by 50%.
“Ultimately, SEPA 2.0 will empower us architecturally in our ongoing quest to redefine the mobility experience with compelling value, excellent convenience, and rich information and entertainment,” Xiaopeng said.
