From what I understand, carmakers have average emissions quota across their whole range (95g/km of CO by 2021).
Having electric vehicles in the range is a way to meet the quota even if they don't sell really well.

If a car manufacturer actually makes and registers low-emission cars just to keep the average of their fleet down, there's not really a point in just having them sit around collecting dust, so they might as well sell them.
