I have a 2020 and KIA tech said they tweaked some things.I have an AWD and he said they did some software and tweaks to make it shift quicker along with the AWD tweak which he said also gets it off the line quicker.I only have 2k on mine and it is 95 degrees outside.Maybe when it cools down I will do a run to see.The car is plenty fast for what it is.BTW one of the fastest RWD runs--someone had linked it and at the bottom in micro letters--it said "best of 5 runs".They said a 2020 AWD after break in should hit mid 4 to 60.I also have 93 and 94 octane near me so the gas is very good--which also makes a diffrence. The 2020 AWD and RWD accelerate the same they told me(if they are on even flat pavement--any other surface--rain--or anything else and the AWD is faster).Like the video above--I am sure a mid sec 4 is what the car can do.BTW the AWD will do better overall because it should hit its 60 the same everytime.RWD--you risk wheelspin--and it has to be perfect.You run 5 runs in a RWD stinger and 5 in an AWD and the AWD will probably run on average quicker cause all you do is punch it. And like the other dude said--variables--weather--AWD will go faster on average cause it handles the bad pavement--weather and traction better.
