Converting from RWD to AWD on facelift US-market Kia Stinger GT1 using weight adjustments on HPWizard ONLY (with improvements from TorqueStats-estimated acceleration and distance times for RWD version)
Normally, I would use TorqueStats first and then HPWizard, but I also like trying something different. I've been getting too used to seeing all solutions remaining equal and wanted to try out some new (and relatively creative) things.
Curb weight: 1670 kg (RWD) -> 1868 kg (AWD)
F/R weight distribution: estimated 52/48 -> 55/45 for AWD models
Solution for the two entries above: 1670x(55/52)^2 = 1868, + 75 = 1745 kg for RWD and 1943 kg for AWD (!!!)
0-60 mph: 5.4 sec -> 4.1 sec
0-100 mph: 11.8 sec -> 11.3 sec
1/4-mile: 13.4 sec @ 111 mph -> 12.5 sec @ 109 mph
Top speed: 170 mph -> 168 mph

RWD: (((((((900/(30/25)x(1745x2.20462262))/0.052)/421))/1.17)x0.70x0.73)x4.5 = 25.9 sec @ 0.86 G
AWD: (((((((900/(30/25)x(1943x2.20462262))/0.052)/421))/1.17)x0.65x0.76)x4.0 = 24.8 sec @ 0.93 G

RWD: ((20600m/(250km/h/((192m)x0.3048m))x(1745kg/421hp)/1.17g)x0.0095x0.625 = 8:09
AWD: ((20600m/(250km/h/((193m)x0.3048m))x(1943kg/421hp)/1.17g)x0.0095x0.575 = 8:24

RWD: ((3682lb+75kg)/421hp)x((1.75mi)x12)x.70x.73x0.9 = 1:26
AWD: ((3682lb+75kg+198kg)/421hp)x((1.75mi)x12)x.65x.76x0.85 = 1:27
The GT2 may be much slower than the GT1 and a bit closer even to standard-for-US-market GT-Line due to added weight from features and especially when equipped with all-season tires.
