Picked my BYD Atto 3 up last Tuesday, and now have done around 1300km on it heading up to Girona and back. Definitely a decent hit to range when on the motorway with me probably getting 380km to a full charge, with a mix of 110-120kph and set to cruise control. Did catch me out a little on the way up, as i'd had the car less than 24 hours and wasn't really organised. We charged at a Tesla supercharger but i didn't go to 100% and then needed to charge again just before Girona as i hadn't realised how much it's drop. On the way home i was fully charged before setting off from the hotel and only needed a single charge on the way back home and finished with around 20% so that was better.
I rarely do such long trips though so it's not something i'll be too worried about in future as will just charge at home which will cover around 99% of my journeys.
Been a lovely car so far though.
