I have the DS3 Crossback E-Tense. I wouldn’t have another. The buttons resolutely ignore my presses, collision warnings bong regularly for no reason, the tyre pressure monitor regularly flags up warnings that don’t exist and the proximity KESSY is unreliable. Lane keep assist wants to constantly fight me on anything but motorways. I normally switch it off when I get in the car.
Updating the sat nav requires that you download over 17gb of data as there’s no region/nation choice until you’re installing it. What a waste of time and data.
As far as range is concerned it’s fine around town. In summertime I can get circa 210 on mainly urban journeys. Summer motorway is around 150. Winter time drops drastically with lights, heating etc on. About 2.5 to 2.7 is not uncommon.
