Getting a good 0-60 time

I had my 2019 out for a drive and figured since the roads were clear and dry and I was running the Torque ODB2 app, I would try for a few 0-60 pulls. Usually with an automatic, since you can't dump a clutch, with my foot on the break, I bring the RPMs up a bit for a better launch. I found this is impossible since the computers seem to dampen this from happening. Until the RPMs raise you really don't get full-on power. Once going, it chirps the tires in second gear. The best I could pull was 6.5, 6.6 which is published as what it can do, but I feel if I could get those RPMs up I could get a faster time.
Does anyone know the secret to launch this better?

Nothing I would recommend to someone who actually likes either their brakes or transmission, but the usual two are:

Use the emergency brake to keep the car still while revving and then drop it. No idea how that works with our electronic ebrake. It might work, when I first got the car I sure did start to try to drive while the brake was up (it took me a second to get used to not having the old regular brake lever/handle). Maybe the auto doesn't let you do that, but nothing stops me from being a dope with a manual transmission.

The other way is to put the car in park or neutral on the transmission, rev like mad, then dump into gear. I knew kids in high school who would do these "neutral drops" all the time on cars their parents leased for them. I drove a clunker and was just happy to have a car that ran.

Engineering Explained at the end of this video shows how Hyundai's DCT handles launch control.

Some DCTs will have a 'launch mode' that gets activated if you hold the break and then press the accelerator all the way to the floor, then off again... but I've never tested anything like that in the Elantra GT, since both of mine have been manual.

If I launch from about 3.5k RPM in my manual I spin the tires briefly, then chirp going into second(as long as traction control is off). Not sure what my 0-60 times are, but a critical part of getting a good launch on these is to have your boost up. Which is still tough to do from launch if you've got no load -- since you're not making a ton of exhaust gases just revving in neutral.

Might be worth doing a like a 10 roll lol after some spirited driving.

I think the e-brake is perhaps maaaaaaybe something to look into, but a neutral drop is not something I am willing to do. I've one these when I was in my teens and with cars built like tanks LOL.

E-Brake is auto release.

Best thing to do is what EE shows at the end of the video.

Or do a 10 roll.

E-Brake is auto release on the DCT? It sure isn't on the manual transmission. Maybe the DCT version of E-Brake operates like the hill assist by default.

I drive the manual and it's auto-release. I'm 99% sure it is on the DCT too.

Keep your ebrake on and come off the clutch slow with some gas. It'll feel awkward but it will disengage. It's possible OP might actually be able to use this this auto-release time to rev up and get a launch.

EDIT: Looks like it's true for the DCT as well.

"The brake will automatically disengage if the doors are locked, the engine is on and the driver shifts into “drive” or “reverse” and presses the accelerator pedal. You will be able to hear the parking brake reset."

That's great news. The second time I tried to pull out of my driveway the brake was definitely on and I felt the resistance and immediately hit the clutch pedal and did a mental dope slap. I probably just stopped before it had a chance to auto release. Now I can stop being so paranoid about the E-Brake.

The e-Brake in mine releases as soon as you touch the gas, so a no go. That video posted was so informative.....thanks.
I guess it is what it is. Between the DC and the Turbo lag and electronic protection, not the quickest to launch.

Yeah I think Hyundai was probably like 'if you'll be launching you'll probably be driving manual' --- cause we have Launch Control built-in.

I think you practiced enough though, you'd probably be able to get a decent tire spinning launch(and then dial it back a bit so there's no spin) using the break and gas in perfect timing.

The other thing you might want to try is fully disabling Traction and Stability. That MAY disable Hyundai's launch prevention on the DCT.. but I literally have no idea.. you'd have to test it.

You do that by holding the Traction Control button for 3-5 seconds. It'll show that both turn off.

Thanks for that tip, I will try that for sure.

Just chiming in with an anecdote:

I tried figuring out a form of "launch control" on this car shortly after I bought it. We previously (unfortunately) had a Ford Fiesta with the cursed DPS6 DCT, and you COULD actually "launch" the car by holding the brake and revving it, then just releasing the brake with the gas pinned. I would rev it between 2-3 grand, then brake-lift. It would slip it quite a bit and rather aggressively and would definitely get the car moving faster than just mashing the gas from a regular stop, as it didn't allow slip for a faster takeoff. There were plenty of times I did that just to get the car moving (not a lot of power aside from crap trans).

Tried it with the '18 Sport, and the '19 N-Line. No dice with either. As soon as you try to rev it with the brake, it just engages the clutch and tries to move forward. Most vehicles have a rev limit programmed if you're on the brake or in Park/Neutral. Typically around 3 grand RPM. Though funny enough it may allow a brake torque. Haven't tried it, though, and not feeling inclined to.

Sport mode maps more aggressive throttle, and bumps idle up another 100 RPM or so anyhow.

Brake torquing a FWD vehicle could be amusing. If only in a silly and ironic sort of way.

On the manual the rev limit in first gear is 5k RPM. I suspect it would be similar for the DCT.

It's WAY too high to launch at 5k with stock tires. You'll spin for days.
