I was surprised to see that the rear portion of the car wasn't as heavily damaged, but when they picked it up, I noticed the floor appeared to be one large piece. My guess is, that was able to absorb enough of the crash energy, to bring the vehicle to a stop.

Why???

Money. This was done by a company for their website and probably some of their magazines. But from a personal point, the journalists probably did it so someone pays for their chance to build this beauty, and they let it crash so they can afterwards enjoy to build it a second time..

I have made one of these and it is not one piece. The floor is just very sturdy because it has a lot of long flat bars and is very will connected with a lot of fixings.

The “skin” of the car on the other hand is very flimsy because they had to use a lot of tricks to get all the panels to have the correct angles with only standard LEGO parts. Many of them will flex when you touch them because they only have 2 attachment points.

I can highly recommend making this model. It has a 4 speed transmission with paddle shifters on the steering column. It’s one of the most mechanically interesting models I’ve put together, and yet all of the complexity is practically impossible to see once the model is made.

One question I have, was the speed of the crash test scaled down to factor in the scale of the model or was it done at the full speed of the full size car. If it wasn’t, it wasn’t a very fair test!

The description says 46 km/h, not sure how fair you could make this ;P

So, how many parts were actually damaged after this?(probably only a couple)

And the good bit: you can put it back together again!

This is what they mean with rapid disassembly I guess. One of the problems in the Lego sorting project is how to disassemble sub-assemblies that arrive in unsorted lots and that's a very hard problem to solve due to all the various ways in which the parts can be assembled. This is a pretty nasty way of solving that particular problem but the number of parts damaged would have to be very low for this to be a feasible real world solution.
