It’s strange the interior being identical between the x1/2 we drive the x1, only sat in the x2 but the x2 do seem bigger and slightly more shoulder width, seems to give the effect of being a larger space.. Very quiet & peaceful place to be seated I noticed..
We had the exact opposite impression @ajn 😂 The front felt the same in both cars (which it’s is) but the rear of the X2 is significantly more cramped than the X1 due to the raked roof line. I really struggled to get into the back of the X2 and had to really crick my neck, whereas it was dead easy in the X1. The boot in the X1 is also bigger due, again, to the different roof lines.
We need space for a wheelchair and want to be able to carry adults in the rear occasionally, so the X1 would be far more practical for us but if, like @joss you don’t need to do either of these things then the X2 is the one, as it has a much nicer looking rear end 😂
Unfortunately, when we were last changing it was only the iX1 and iX2 that were available, and having had a few on extended test drives I didn’t like the EV driving experience, as it didn’t feel like a BMW to me. Had the X1 been available I think we would have gone with it.
