I cant beat your efficiency. That's impressive numbers esquire. I am rocking 3.1 miles per KWh with mainly urban and A roads and a little motorway (hilly but with up and downhill so should theoretically even out id have thought). I do have an F-sport so don't know if that makes things worse. Real life I am getting early 50's now in electric so happy with that. My May stats are 450 miles with 79% EV and 243 MPG (most of my daily (return) trips are inside the electric range). Out of interest how do you use the car? Start in EV and let it run out? Manually switch between EV and HV or put it in auto and let it decide?
I am beating you on the charging front....got the Hive charger and years free charge offer. Just hope the smart charge is still about when I come off it!
