So I just purchased a 2018 Stinger GT1 3.3l twin turbo with only 10k miles on in and i've had it for about 2 months now. When the kia dealer was selling me on it they said it had launch control, it shows it in the user manual (but pictured as a GT2 in the manual). When I turn off EPB and ESC while in sport mode, holding down the break and starting to press down on the acceleration, the engine starts to shake more than I would expect. I also do not get a "launch control ready" when doing so on my hud. Can anyone clarify if the 2018 GT1 has launch control or not? and if it does, are those irregular shakes normal? I dont want to destroy my transmission trying to do something if my car doesnt have it available.
