These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the BYD Sealion 7 and Deepal S05 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 204 miles for the BYD Sealion 7 and 231 miles for the Deepal S05 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Deepal S05 goes roughly 27 miles further between charging stops.

Which battery will hold up better as a used buy, the BYD Sealion 7 or the Deepal S05?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the BYD Sealion 7 and 90% for the Deepal S05. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day.
