Even the most mundane econobox will have prototypes built that cost way more than Porsche, they're driven, tested, fatigued, crashed and then cut up into little tiny pieces so the competition won't be able to get they're hands on anything that they could learn something from.
For every Porsche than Porsche crushes I expect Ferrari, Mercedes, Aston etc do too or at least the third party Engineering firm they've hired to gather the data does.
Still sad to see though.
