When I was considering the Mitsubishi Outlander PHEW last year the problems concerning my scooter and hoist was the lack of space.
The boot space was its downfall for me but if the boot floor and rear door aperture is big enough then everything will be fine, but yes, electric motors under the boot floor can cause problems with hoist and scooter loading because the petrol and diesel version of the Outlander did not have that problem.
I’m just hoping by the time I order my next car that technology has moved on and designs overcome this problem, but then, maybe the problem is only a problem for hoist and scooter/wheelchair users so not a big priority for manufactures.
