I get or exceed the wltp (273 miles) for about 8 months of the year and get less for about 4 months of the year. LRTC 72 model. I drive at about 65mph on the motorway (or less if prevailing traffic conditions make it so) using ACC / MG Pilot. I turn on/off heating / air con as and when required. If the temp is comfortable I will switch it off until I need to turn it back on. When I went to Cornwall last summer, on my journey to Exeter (I have always stayed overnight on the way there, irrespective of car type), I got the equivalent of 270 miles, fully loaded, 4 passengers ( 2 adults, 2 young teenagers) , with a Roofbox (albeit an aerodynamic Thule one designed for EVs). Going to Stockport from Londom last December (28th) in lashing rain (fully loaded with 4 again but no roofbox) , after a journey of about 190 miles , I had about 30 miles left. ( started at 100% charge). I charge using a granny charger at my folks so was not bothered about only arriving with 30 miles left.
