Using a VBox on my fastest run of 3.04 I had 1.318Gs. But most of the time it’s 1.0 or .9x.The difference in g-force:
0-60 in 3 flat (P3) is 0.91g
0-60 in 3.5 (LR AWD w/boost) is 0.78g
0-60 in 3.9 (LR AWD no boost) is 0.7g
I find those differences noticeable but not jaw dropping any one versus another...
For contrast, a P100D in full ludicrous 0-60 in 2.28 is 1.2 gs and that's still a pretty holy crap/neck snap feeling compared to any of the others.
Edit: The 3.04 was with a 1.55 meter incline.
