Quite sad indeed. Take the Sauber C9 for instance, my favorite car in GT4. In GT4 the sound of the car was to die for. In GT5 and GT6 it sounds like a dentist drill. I'm still mystified as to how PD could totally screw up the sound of one of the most beloved cars in the game especially after it sounded so good in the previous version.
It sounded wrong in GT4, also. It's the same sample as the TS020 used. It's another perennial, in that it was applied to many of the racing cars in GT2 (e.g. both Lotus GT1s, just from memory). It's a very annoying loop, which might be why it's not heard so much any more (if at all?).
I wonder if that is new way of creating that rasp certain cars have. On some cars its good but on every car using this new method you mention, its more pronounced and more easily heard.
I think these clips are the first hint of what the Red-Bull- / Senna-style sounds could be if they were toned down a bit to be more "realistic". But they only achieved that by including intake sound, which is unmistakable in those snippets.
The crunchiness seems inherent to the method outright, as it's audible in the intake too. We have to remember that it's mixed in with music, speech and other effects in the video, so there is considerable masking; a full "quality" assessment cannot really be made. It might be that it still sounds dubious in practice.
There is the tiniest possibility that this crunchiness won't be present on PS4 (it implies low bit depths somewhere, potentially), and so that might be what Kaz means by "major". But that's really reaching, I think.

Ooh, how did you do that? Reverse image search?
The workspace is "Mastering" something or other (can't read kanji; not that I can "read" kana either).
The file name has a date (1st Feb 2013) then a load of numbers. It's a long file at over 40 seconds, and the non-steady-state recording probably indicates it's not really for generating samples with, only for reference. The histogram probably says something about the adequacy of the recording technique / microphone used.
The highest frequency in the spectrogram is somewhere around 70 Hz; that translates to about 8500 rpm for a four-stroke. Counting the harmonics, we get a strong fourth and an even stronger eighth (plus substantial 16th); there's a lot of energy between the 4th and 8th harmonics at lower rpm. It could be the exhaust sound of something like the HSV-01, or F355 challenge, a GP2 car etc.
