Xiaomi SU7 vs BYD Seal
The SU7 Max against the BYD Seal AWD Performance. BYD no longer sells the Seal in China.
BYD Seal is a vertically-integrated alternative from China's largest EV maker; SU7 is the consumer-tech entrant. They target a similar audience and price band but make very different bets — battery technology, software, and ecosystem. BYD has taken the Seal off sale in China, where the Seal 08 is now its flagship Ocean sedan, so the Seal price below is its last China list price.

The SU7 Max is the better paper spec. The Seal cost about $7,000 less at its last China list price, is still sold outside China, and comes from a far more established EV maker. In China, BYD no longer sells the Seal new, so a buyer there is choosing between the SU7 and a used Seal. Outside China the SU7 is not on sale yet, so the Seal is the one of the two you can actually buy. China prices checked 2026-09-28.
