Yep, they're really doing this.
Because of the way they're used, pickup trucks should generally be made from materials that are easy to repair. Until a new material can be shown to be easy (and cheap) to repair, pickup buyers are going to be very wary of it, and this is pretty understandable. This is why Edmunds has taken its aluminum-bodied long term test F-150 and whacked it with a sledgehammer. And it must be said right off the bat that this thing is not easily damaged.
We'll have to wait to see the results, but it's safe to say they seem pretty committed to this premise.
