BYD — to Romania, in my area I have to recharge 5 times.
Audi Q5 — to the same place I refuel only 2 times.
At the end of the merry-go-round, if diesel doesn’t rise again, I can say I travel with peace of mind in the Audi — both on price and comfort 😆😆😆. If I switch on the air conditioning in the BYD, I’m totally screwed; for 1,350 km I’d need solar panels just to keep costs down.
But if I only drive around the city and do short runs, all praise to BYD.
