Powertrain details

The Aiva ME7 is powered by ternary lithium-ion batteries manufactured by CATL.

• Single-motor version: Equipped with a rear-mounted motor (Model QT63TZ220001) produced by Chongqing Qingshan Industrial Co., Ltd., delivering a peak power of 270 kW (362 hp).
• Dual-motor version: Features an all-wheel-drive system. The front motor (Model YY63YS230003), produced by Chongqing Jinkang Powertrain New Energy Co., Ltd., provides a peak power of 150 kW (201 hp). The rear motor remains identical to the single-motor configuration, offering 270 kW (362 hp) of peak power. This brings the total power output of the four-wheel-drive model to 420 kW (563 hp).

CATL put two high-end CTP 2.0 battery pack production lines into operation at Seres’ factory as early as June 2025, enabling local battery production and “production-to-installation” delivery, with nearby power battery systems for flagship models such as the Aito M9 and M8. A week ago, Seres and CATL signed an agreement to accelerate construction of Phase II of the “factory-within-a-factory” project. Phase II is planned to have an annual capacity of 10 to 12 GWh; once completed, the combined annual capacity of Phases I and II will exceed 20 GWh.
