I did the same Manchester airport run on Friday to pick up my son. A180, m18 m62 6 am freezing, 260 miles round trip. Preheated battery and car while plugged in with 91% charge. We stopped at hartshead moor eastbound for a breakfast bun and coffee while topping up to @95% at one of the apple green chargers at end of the Tesla charging row. nice to see another bank of chargers being installed behind them. Through to airport then topped up at the Tesla chargers to @90% in Trafford centre before running back 130 miles non stop. Heater on, 70mph. Both chargers were fine and we got back with 35% charge left. Compared with the previous iD3 heat pump it was more noticeable drain with heating on to defrost windows on m62. It was cold.
