Launch control, what a JOKE..

The LC is very stressful on the drive train, so says the manual. I can't imagine that holding the brake down while pushing on the gas to bring up the RPMs is good on the car either. But as long as it is used as rarely as the LC is designed for, what do I know?

It actually might be easier on the drivetrain to do it that way. When using LC the RPMs build to around 2100. I doubt the ECU will allow the RPMs to climb that high without LC. It'll probably pull power at 1500 RPMs or so.

If I understand what you are describing: the car has built in limitations such that if you hold with the brake pedal while pressing the gas pedal the RPMs won't climb above "1500 RPMs or so". But the LC is a built in system that allows up to c. 1000 RPMs more than that. If I understand this correctly, then yes, holding the brake and pressing the gas at the same time would definitely be easier on the drivetrain: but also not a comparatively effective "launch" of the car in a duel (either with another car or the clock).

Harder or easier on the transmission isn't the primary concern, although it is a concern in the end. A torque converter is a fluid coupling that connects the power output of the engine to the transmission. The transmission "transmits" power to the rear (or all) wheels. In a simple explanation, the torque converter converts engine motion (revs) into heat while the car is sitting still. Energy can neither be created or destroyed, only converted in form. In this case, kinetic energy is converted into thermal energy.

Increasing the revs while holding the brake increases heat in the fluid. Increasing the time of revving contributes even more heat to the fluid over the time that the engine is revved and the brakes are held. (This is why launch control "times out" after 3 seconds or so) It is this heat that breaks down and damages the transmission fluid. The transmission fluid is what lubricates and operates the transmission. So, if you damage the fluid, you damage the transmission ultimately.

This is why so many add, or increase the size of, transmission coolers on their cars if they have increased the power output of the engine.

Holding the brake and pushing the pedal without LC still limits the rpms to 2K

Just for shits & giggles I used the launch control feature today. Very effective - produced efficient, quick acceleration with no drama.

My only real complaint with the Stinger thus far, as juvenile as it may be, is that lack of drama. Even turning off traction control and flooring it without Launch Mode enabled won't produce any wheelspin. Not even a chirp. I feel kinda let down after viewing all the smoky burnout vids, though those cars were likely not the AWD version. It hooks up really well and pushes me back in the seat, but with no noise other than the engine revving. I'm in my mid 50s, so should be over the need for this type of display of wretched excess, but I'm not.
I will never be over this need . I like smokey burnouts and going sideways. Your not alone

I would just see money going up in smoke. Smoking tires offend me, both aesthetically and economically. Efficiency is my joy. Zero to sixty in "4.7" is very, very cool. But please, no "sideways" and no smoke. The Stinger is that kind of car. :D
 
As an AWD owner I can say there's very little perceivable difference in LC between the two models. The difference in time is negligible between the wash of AWD itself vs increased weight. I tested LC on both models and noticed they were just freaking fast no matter what.

Just enjoy what you have, no reason to completely dismiss one trim or model due to a nearly-imperceptible difference in LC...

AWDs are 14 PSI boost and RWDs are 12 PSI boost. So in stock form they are nearly just as fast.

When I get mine, I will most likely pick up spare, cheap wheels for the track - or perhaps get something custom for daily use and put track tires on the stock wheels. Either way, I plan on a LOT of sideways and smoke!! Obviously, not on Pilot 4s!!

It's killing me we have a track day coming up at Road Atlanta shortly. Hmm... anyone local want to see what their Stinger can do? :) Professional driver, closed course, that sort of thing..

This is something I don't want to watch, not even from the passenger seat. When/if my Stinger gets to cut loose, it will be driven by me. I already know its potential: the numerous videos available address that adequately. I will find out what I can do in it.
 
I'm sure you know I was joking. You'd have to be mad to let me drive your Stinger.. oh.. wait..

:rofl:
 
Life is strange. Just the very next day, and I do more than just try the LC. I was on my way home from the NW, and the NAV directed me down through central Oregon, past Burns and heading toward Nevada on Hwy 95.

The forest scenery prior to that was gorgeous and the road very fun to drive. It dropped down to the wide open spaces and should have gotten quicker. But Oregon loves their 60 mph highways. South of Burns all traffic virtually disappeared. I practically had Hwy 78 and 95 to myself.

The speed demon in my head whispered: "Dougy, you know that the NAV brought you here to play." And I didn't argue for even a second.

There was no traffic behind me, and none approaching. I stopped in the middle of the road, disengaged the traction and stability control, pressed the brake pedal and then the gas and let the brake go. The car took off, but not as fast as I had expected in "launch control" mode. What is more, I had forgotten that I had the shifter in manual gate and was supposed to do the shifting. Some "nanny" override compensated for my dumb oversight and killed the acceleration when first gear got into the red line. Man! It shifted up but the "whoosh!" was gone. That felt really weird. The car was in control, thank you Kia: you won't readily allow me to break my car!

After a couple of minutes I found another long, straight spot with visibility going forward and back a couple of miles, and stopped again. This time I put it in Sport (I had been in Smart the first time, which engages Sport when you floor it, that's why the LC worked at all, I guess, heh!). I launched and it went better. I took the top speed up to 130-something and then slowed down.

I was done with launch control. I wanted to try taking off from "auto hold". I put my left foot on the footrest, positioned my right foot just so over the gas pedal and gave it the guns (remembering to shift this time). Better! I did this a couple more times, trying out letting the car shift for itself, and then alternating using the paddle shifters.

I found the area between 4K and 5K RPMs to be the best shifting point; it doesn't waste any time shifting there; whereas if you take the RPMs up close to the red line (or c. 6K RPMs), it tends to shift with a little more delay, which kicks the RPMs even higher. So, I enjoyed all of that.

Then I decided it was the time and place to test speed. On two of my launches I had taken the speed up to well above a hundred. This time I was already going pretty quick, c. 70-something, nobody was round, fore or aft, so I put my boot in it, using 7th gear, watching the RPMs climb slowly and indicator clicking up and up, slowing as it passed 140. It reached 150 and I kept at it; the acceleration was still pretty good, about a mile per hour per second, I think. So in another c. five seconds I saw the indicator (the display, I wasn't watching the speedometer in any of these "tests") reach 155, my spontaneous "goal", and I backed off, and used the brakes to bring my speed down quickly (prior to this I had just let the car decelerate on its own without brakes).

That run was a rush! The car had been loping along the slightly undulating road surface, stable, smooth and quiet. I am sure I had a stupid grin all over my face.

Just a couple of minutes later I saw a sign that said, "Go slow. Prepare to stop." So I did that. And up ahead I could see a roadside guy with a Stop sign flipped toward me, and a single car already sitting. We sat for over five minutes while a mere trickle of opposing traffic came by. Then a truck with a "Do Not Pass" sign in lights facing backwards took station in front of us (there were at least three of us by then) and led us for a few miles and then turned off and let us go. I have no idea what that was about. The speed rush was still with me and I was satisfied with the day. I tried no more foolishness. There wasn't another opportunity anyway, there was traffic again; no spaces; no solitary road just for me.

Reads like an article from a reputable automotive publication. Well done! I am getting the sense from many posts here on the forum that the launch control isn't much of asset. The few times I have done it, I have to say, I was left a bit disappointed. It did not feel at all different from regular acceleration from a stop to me. In the case of the Stinger (no dual clutch tranny or trans brake), I feel it is little more than a gimmick.

On a side note which may be food for another thread, I'm a little curious about how braking at 155 felt. Any unevenness in brake force seems to be amplified at higher speeds in my previous cars. I had a Genesis that would pull from side to side when braking lightly to moderately at elevated speeds. Ever since then, I very gently apply the brakes at any velocity over 100 mph. Did the car track true when the brakes were applied?

Perhaps it was included as more of a "gimmick", to someone experienced with actively "launching" their own cars. Anyone with drag/dueling experience would just ignore the LC; that's what I think now. I have no dueling experience, and plan on that remaining true (you know what "they" say about, "The best laid plans of mice and men", heh!). However, after reading on this forum about LC, I suspected exactly as you say: not an asset, just included in the list of cool features/abilities of the Stinger. Someone not competent in putting his/her foot down might find the LC an assistant in getting accustomed to the feeling, then go from there, as I have so recently done. At least now I know that LC isn't going to freak me out with some sort of massive "G force". If anything, it is less than what I can perform on my own any of several ways.

A "non-gimmicky" launch control would rev the car close to the peak torque and then release the transmission either through a clutch drop or releasing the trans brake. This is an example of a "real" launch control...

While I was still "pinging", I shot this video. Dropbox - MOV07225.MPG In it I expound on my experience a bit more. Enjoy being in the presence of an enthusiastic tyro. :p

I see that there was rather more opposing traffic than I remembered: it explains why there was nobody coming toward me during my fun; making it possible, in fact; without the long delay up ahead, I'd never have had the road to myself, and I would never have tried out all of that fun Stinger performance stuff! Serendipities of Life: and sometimes we actually notice soon enough to take advantage of them.

(Until this morning, I thought that I had lost the video, or rather, failed to shoot it at all; because when I ended it (c. a minute beyond the cutoff point), I looked at the back of my camera and it showed "REC" in glaring red; which means that instead of turning the video shoot OFF I had just turned it ON. But on reviewing my camera contents I discovered the video intact. Then I remembered that for some esoteric "reason" Sony dictated that their Cybershot should only take videos that are a maximum ten minutes long. Heh!)

Well , I must say after one month of ownership I believe I made the right choice over the 2018 Mustang GT . Many times this car puts a smile on my face. Still learning this car and more mistakes will be made. Driving this car because I'm Happy, like a room without a roof LOL..
 
I finally tried this. Twice. So rare to get a spot alone an anything resembling a "highway" around here sometimes.

Anyway, the first time, it seemed to take forever and at the same instant it finally said "Launch Control Engaged", or whatever it is, I released and it took off. Eh, it was OK. I told myself I needed to really wait for that message next time and tried it, but got impatient and released at almost the same time again.

So, I have no confidence I've done it properly. It seems to take a solid 3-4 seconds to engage and that's just nerve-wracking on a public road, hoping nobody's coming. LOL

I'll try it again sometime soon.
