## Recent Weekly China EV Sales Data
**Summary:**
In the final full week of April 2025 (April 21–27), major electric vehicle (EV) brands in China saw a significant increase in insurance registrations, a primary proxy for weekly sales volume, especially as deliveries usually surge at month-end[1].
### Key Weekly Results (April 21–27, 2025)

| Aito (Huawei-Seres) | 6,850 | +56.8% |
– **Notable trends:**
– BYD continues to dominate the Chinese EV market by a wide margin[1].
– Tesla remains the leading foreign EV maker, though domestic brands show strong growth.
– Nio and its new sub-brand Onvo posted significant week-over-week gains; Nio Inc’s combined registrations were up nearly 30% versus the prior week[1].
– Aito, a joint brand by Huawei and Seres, also saw a marked jump[1].
### Other Noteworthy Details
– The recent surge aligns with patterns seen every month, where manufacturers push for higher deliveries at month-end[1].
– New entrants such as Nio’s Onvo brand saw registration numbers nearly double in a week, reflecting successful new model launches and delivery ramp-ups[1].
– Industry-wide, China’s EV sector continues to see robust retail penetration rates, surpassing 50% in recent weeks[2][3].
### Additional Context
– China’s total electric vehicle registrations reached 1,237,000 units in March 2025, up sharply from 686,000 in February 2025, confirming the broader momentum in the sector[4].
– The electric vehicle penetration rate approached 53% for passenger cars in recent weeks, underlining the ongoing transition to NEVs (New Energy Vehicles) across the country[3].
### Data Access Changes
– While weekly brand-by-brand sales data was historically published by some automakers (notably Li Auto), the China Association of Automobile Manufacturers (CAAM) recommended halting frequent public disclosures in March 2025. As a result, direct weekly figures for all brands may be harder to obtain going forward, though insurance registration data remains a useful proxy[1][3].
