I had my best run since received at end of November on Thursday. Coming back from South Coast stopped at Heathrow T5 superchargers to 95%,Not really by any noticeable amount. My best trip so far (since Nov) was doing a steady 50mph on an A road temp 5 degrees for a couple of hours it was doing 225 watts per mile, or range of 270.
carried on home to Bradford at fastest legal speeds (yes there were roadworks) but I was amazed at the final result 205Wh/m. It was about 13 degrees and must have been a bit of a tail wind
