4.0+8.7/(4.0+8.7)x12.5 = 12.55sec standing quartermile time at 123mph.
Acceleration off the line: 6.737245 m/s2 = 0.69 G = 0.30sec 11.5" rollout
12.55-0.30 = 12.25 dragstrip quartermile.
With terrain-gear launch: 3.2+7.8/(3.2+7.8)x12.5 = 12.05sec standing quartermile time at 124mph.
Acceleration off the line: 9.70209 m/s2 = 0.99 G = 0.25sec 11.5" rollout
12.05-0.25 = 11.80 dragstrip quartermile.

1620 kg curb weight including downforce, so for Komfort models it's 170 kg of downforce while for Sport models it's likely around 270 kg of downforce. In reality, they weigh around the same at higher speeds (say, post-200km/h). The car makes "official" peak power at 6500 rpm, but it really does continue to make more power toward 7500 rpm (its likely fuel cut-off, or 500 rpm above the supposed "redline"). But shifting points remain at 7000 rpm where it makes 484 mhp. The 959 makes 518-519 mhp at top speed.
Note that the test consists of both rounds: the first simulation excludes the "gelände" (terrain) gear ratio, while the other includes it.
