The answer in one paragraph
The BYD Da Tang EV 950KM RWD is the range-first choice in the new Da Tang family, not the performance-first choice. BYD officially markets up to 950 km of pure-electric range, a seven-seat full-size cabin, second-generation Blade Battery flash charging and rear-wheel steering for the Da Tang EV family. The 950 figure is CLTC, however, and BYD's China flash-charging experience depends on compatible high-power infrastructure. For export, the correct purchase is conditional: choose it only when the VIN-level specification, charging connector, local registration and after-sales plan are all proven.
Choose 950 RWDLongest stated CLTC range and lower drivetrain complexity than the dual-motor AWD version.
Choose 850 AWDTraction and 3.9-second family performance matter more than the maximum range headline.
Choose Tang DM-iPublic charging and high-voltage support are weak, but gasoline and hybrid service are workable.
