Yep – totally agree fwippers – there are two many of us returning similar figures for it to be written off as people that don’t exceed 50 and are freezing or sweating in eco+ mode.
Overall so far I have averaged 5.1 – at a time when I have tried out sport aircon etc.
Like you I have settled for eco mode but with smart recuperation on – I sometimes use left paddle to come to a complete stop.
When it is hot, which it has been often I use a/c on low and ventilated seats.
