I think bootspace numbers can be deceiving sometimes, I know a lot of cases where the car with the less L has more practical space if that makes sense.
I know what you mean, but 466L is substantially less volume. Our Volvo spends 95% of its time with the rear seats folded flat so I’ve been comparing luggage capacity for all these cars with the seats folded too, however that figure for the Ariya is conspicuous by its absence, even on the Nissan site.
Re looks of the iX1 versus the Q4, from the front I think the Q4 just looks ok, whilst to my eyes the BMW looks like a caricature.
