On the face of it, the BYD Sealion 7 has it all: it’s shockingly quick, immensely spacious, feels beautifully built, and has an impressive range, and it even looks the part, too. But don’t sign on the dotted line without driving one first, because in the flesh you’ll encounter its less-than-perfect ride and fiddly infotainment screen. You’d do well to remember its range and efficiency aren’t the best, either.
