Isn't it sudden change in the torque which causes the slip? Once slipping it is easy to maintain This is why you can spin the wheels from pulling away easily. I've not had too much trouble spinning mine at motorway speeds either given a bit of provocation ;-) the joy of FWD :-(
I think the point with the heavy car is you are more likely to be putting more torque on the clutch compared with the lighter one for the same results. Hopefully some of that makes sense.
