It's competition though is what I did instead. Last year I brought a 7 year old Nissan leaf.
£9,800. 22Kwh battery (probably degraded about 15%, so estimated actual capacity is around 18Kwh) which gives me about 85 miles range with the current battery state. And I get a decent sized boot, 5 seats and 80+mph top speed.
I love my leaf, and use it to commute around 20 miles total each day plus lots of other local travel. It's perfect as a 2nd car for town driving.
However, that 85 mile range is only in good conditions. With the heating on in winter it's range is probably more like 40 miles. I'd say this Citroen's battery is too small for me to buy compared to my leaf. 46 mile range doesn't give you much spare, especially in winter when using heating. Unless charge points become a lot more ubiquitous. It shouldn't take them much to double the battery size though, and then I'd seriously go for this.
(Edit to add, my leaf also has air bags and antilock breaks. What with it being an actual car)
