Glos Guy I would say almost certainly the 78cm length would fit if placed seat to door but the 105cm width side to side might be a big ask for the xc40. My wife’s wheelchair is 77cm in each direction and fits in the boot. I think you should do what we did and try your wheelchair at the dealership. I think you would like the inside of the xc40, I know your not keen on the shape, and the b4 engine is quite nippy.
