I have had the ec4 for 9000 miles since last year. It is extremely well equipped with all kinds of driver aids, the semi autonomous driving is useful in long journeys. Using eco mode is a must for good range. Winter range is about 130-140 miles summer I have seen over 22o.
Remember that the usable battery is 45 kWh not 50.
I have had loads of Citroens with all their idiosyncrasies- this is a real Citroen which suits my tastes.
