I actually bought the Hot Version v157 video with the 2019 NSX comparison. I haven't translated the video yet, but the cars were a 2019 NSX on Sportcontact 6 tires, 2019 GT-R Premium on Dunlop GT600 tires, and a 2019 991.2 Carrera S on P Zero N1 tires.
Individual lap results were:
1) 911 - 1'02"488
2) NSX - 1'03"589
3) GT-R - 1'03"654
There were three different drivers for all three cars, the DK "green" guy in the NSX, and two others for 911 and GT-R.
The "Green" guy drove the NSX (like last time), and he also tries the 911 along with a different guy, and they both got about the same lap times. So hopefully the above results are not due to different drivers.
In the earlier video, it was a 991.2 Turbo S and a GT-R track edition, so not the same cars this time.
The 911 was pretty impressive relative to the other two, especially including it's base price of 105K USD.
The "battle" between the three was (with best lap time):
1) NSX - 1'03"342 L2
2) 911 - 1'03"085 L2
3) GT-R - 1'03"650 L4
Overall, the NSX seems to have of the same problems on track as before in the earlier video. Doesn't seem like it wants to allow the traction control to be fully turned off, and regularly intervenes at an awkward time.
In terms of what the 2019 changes mean for non-track street performance in the video, it's hard to say. Translating the commentary may be helpful. Or maybe they will post it to YouTube soon
