Current version has 440 litres of trunk space - but the usability (think about having a dog) is far from megane 3/4 estate version:
I know that current manufactures hype is SUV. But on the road I see a lot sport wagons (passat, megane, bmw 3/5, volvo,... most of them are just estates). And there is no "affordable" estate EV. I believe there is market for this and megane with its thin battery pack has the potential to be converted to estate version. And IMHO estate is more efficient than SUV.
