2017 GT86 vs 2022 GR86 (they have the years labeled incorrectly)
0-60: 7.27s / 6.62s -- + 0.65s
0-100: 18.85s / 15.88s -- + 2.97s
1/4: 15.62s @ 90 / 14.73s @ 95 -- + 0.89s @ 5mph
1 KM: 28.25s @ 118 / 26.67s @ 126 -- + 1.58s @ 8mph
1 Mile: 38.92s @ 130 / 36.90s @ 140 -- + 2.02s @ 10mph
Will be interesting to see if these match up to the real world. The 0-60 for the 2022 GR86 in the game seems slower than what Toyota has been quoting, but there are notable improvements considering the relatively low power gains - more top end would help but that isn't how they tuned the engine; I'm assuming it might be a tad faster in the real world, but probably not by that much.
*** P.S. The trunk looks to be the same size. I recall there being some discussion about it shrinking, but that doesn't seem to be the case.
