XPeng’s SEPA 2.0 architecture includes front and rear integrated aluminum die casting technologies, a practice that Tesla has been using since 2020 to make single pieces of vehicle underbodies.
XPeng said the platform will be compatible with multiple vehicle platforms for wheelbases between 1,800 mm and 3,200 mm, and can support a range fo 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 the driving performance with an improved center of gravity.
The smart manufacturing system will be built out by 2025, the company said, adding that all manufacturing facilities will integrate SEPA 2.0 through technology upgrades.
“We envision that this evolutionary intelligent architecture will lead smart EV technology development for the next three years,” said Xiaopeng. “It will make rapid advancements in technology available for our customers as standard, with faster software upgrades, stunning cost savings and elevated product experience.”
XPeng also said the new architectural platform can help make its infotainment service, Xmart OS, available to every owner. Xmart OS is XPeng’s multi-sensor software and hardware intelligent cockpit, and a key feature is the voice assistant. The automaker said Sunday that SEPA 2.0 shortens the voice software R&D cycle by 50% and reduces the cost of the voice assistant service by 50%.
“Ultimately, SEPA2.0 will architecturally empower us in our ongoing quest to redefine mobility experience with compelling value, superb comfort and rich infotainment,” said Xiaopeng.
