- Xiaomi began deliveries of the updated SU7 in April after securing over 100,000 pre‑orders, adding to the 381,000 first‑gen units sold since March 2024.
- The new SU7 adopts an 800 V charging architecture (752 V on Standard/Pro, 897 V on Max) versus the previous 400 V platform.
- Charging speed improves dramatically: the Max model reaches 10‑80 % in 12 minutes (vs 19 min) and a 15‑minute charge adds 670 km CLTC; the Standard now does 10‑80 % in 20 minutes (vs 25 min).
- Range rises across trims: Standard to 720 km CLTC, Pro to 902 km, Max to 835 km; efficiency improves to 11.7 kWh/100 km for Standard (down from 12.3).
- Standard LiDAR is now standard on all trims, and the SU7’s price still undercuts the Tesla Model 3 in the Chinese market.
Why it matters: Chinese consumers gain a higher‑range, quicker‑charging EV at a lower price, sharpening competition for Tesla in China; the 800 V architecture and standard LiDAR set a new benchmark, while over 100,000 pre‑orders signal strong market demand, and the expanded range up to 902 km CLTC pushes the envelope for domestic EVs.
