Hauling capability is being able to tow safely. Thats the bare minimum. The other big thing is how often do you have to stop for gas. If you are towing a car trailer for example, you have quite a bit of drag. No matter what the power train is, your mileage goes down. Then you introduce things like mountain passes into the mix, and your mileage goes down.
With EV you have to stop and wait to recharge, and at the mercy of the chargers being available.
If battery cells and interfaces were standardized every single gas station had ability to swap cells, then it would work. But we are far, far away from that.
So there are 5 other "pure" EVs with class IV or V hauling capability for sale, and many SUVs. What does "actual hauling" mean?
