It´s unusual nowadays to get more than you pay for, so realistically I was looking at around 280/290 miles in summer and nearer 250 in winter. To be achieving an average in excess of 330 is very good indeed and the weekend before last obviated the need to charge the car at all. I use the car in eco mode mainly, not to save energy as the difference between the modes is quite small, but I find the car a more relaxing drive. Again on the motorway, 65 is sufficient for me, although on my return journey I did up it to 70 for the final 3o miles or so.
Range is the key for many, so to get around 80% of the WLTP in summer would be an issue for me .
