Right. Open road should be more around 770Km. I have a BYD Han 2023 that has a claimed range of 550Km, and I get just about 420Km realistically, at a steady 110Km/h with a few bursts of up to 150Km/h to get away from idiots doing 80 on a 100 (or just to show off the torque to other types of idiots like BMW and some Tesla drivers 😏). I do still get a bit over the claimed 550 if I don't leave the city and drive as if I was afraid of tickets.
