To an extent I disagree. It is probably one of the safest towbars available, but could never absorb the energy of the original dedicated relatively soft progressive crush system that was removed. Nevertheless it does have some absorption characteristics. The main safety cage that protects the passengers is not compromised in any way.

I would confidently say that Volvo has one of, if not the very safest rear end collision scenario cars fitted with a tow hitch.

How long or far down the road would you expect foam blocks or crush cans to last before the hitch dropped off if attached to them?
