Hi @LenaT
Contact a Motability approved adaption installer and they will answer this for you.
It’s rare for a car not to be able to have a hoist fitted, well one that lifts less than an 80Kg but if lifting something more than 150Kg it might be a problem. I’m only talking about experience using a hoist in a ICE car but EV’s should not be any different.
Don’t bother contacting the manufacturers as I too find their websites confusing to say the least but find an installer near you and give them a call, there very helpful.
