@Declan I noticed my miles/kw.Hr had dropped to 3.3 this week as well. It must be the recent drop in Temps.
Bloody hell! It’ll be fun on those January and February days then!
If I remember correctly, last winter it was about 2.7 to 2.9 and sometimes 2.4.
Doesnt really matter, I still got a steady 200 miles out of a 80% charge.
As I said, its not a problem, when it gets to 40 or 50% I charge it up.
The numbers are not worth bothering about. Keeping the cabin temp at 22 Deg, only uses about 9 miles of range.
