How To Launch An Automatic Transmission Car - Torque Multiplication

But doesn't pressing the brake and gas at the same time cause damage to your brake rotors?

I did this and my car stopped and the gas peddle no longer powered the car until I put it in park and put it back into drive….

Best Car channel on the internet, thanks for the content and advice

When I launch my auto, how badly does it actually damage the Torque Converter?

Learned ahlot but I'm never gonna launch mi baby until I get ah back up 😭😭😭

This is one of the best explanations of anything of all time.

Great video. I'm really interested in the application to a car with a turbo. I have a Forester and it's really very sluggish from standstill until the boost comes up. As its AWD and not crazy powerful, wheel spin is never an issue. The trouble is a short run up as you've demonstrated makes no real difference, it's not enough to spin up the turbo. I need to FLOOR it for at least about 3 seconds, then lift off the brake and it rockets away. I've only tried that a couple of times though due to concern about what it's doing to the transmission. It works, but well....

i start in the lowert gear and then move my way up as im laucning like a manual

I have did this a few times in my Alfa Romeo stelvio and when I shoot off I heard the transmission whining like I have a supercharger … It’s a 2021 Alfa Romeo stelvio with 15k miles and no I didn’t beat on it but I did let others drive it and they did drive it like they didn’t care about it ..

Long story short: How To Launch An Automatic Transmission Car - Please, don't do it.

Yea also flip it into sport mode and turn traction control off. And if you have paddle shifter in ur automatic start your launch in first and manually shift thru the gears

Will this hurt the transmission?

Great video!


I am curious how much this affects the life of an S4 2021 tiptronic transmission with 8k miles on it, if you were to do this type of launch 3-4 times, one after another.

One caveat, you only launched it the first time. The rest of the attempts you waited 5-10 seconds until the rpm’s went back down to idle from 3k, then let your foot off the brake because you were waiting for a “launch control” message to pop up, only to find out on a quick google search that tiptronic transmissions don’t have dual clutch and aren’t programmed to LC

I'm not someone you would consider a car guy, but I am in cyber security and my job (hobby as well here lets be honest) requires me to be extremely technical. Recently bought a 718 boxster and I'm really enjoying my journey into truly understanding what is going on inside of the machine I love so much. This is exactly the sort of education I needed. Engineers rock!

Thanks for the explanation. Would this launch technic be recommend on a FWD? And specially, a FWD with CVT?

Thanks

Just redline it in neutral and slam into first gear, just like a manual basically. Lol

Can you do a vid for Fwd Cars ?👍🏼✌

How does this differ from a turbo diesel truck or car?

C'mon it's 2021! Surely by now there are other ways that young men can keep themselves entertained rather than doing stooopid and dangerous things with cars.

Am I being a bit naive here or isn't this a recipe for automatic transmission destruction, especially for a 'well worn' Subaru Forester 2.5 XT with 140k+ on the odometer?
Please don't be a bad influence, ageing repressed 'boy racer' here ;-)

Here's everything you need to know to launch your car.

Oh by the way, don't launch your car.

Can you please shed some light on downhill driving on a TC automatic vehicle?

Buzzkill...

Hi! There seems to be some controversy if this is bad for your transmission. If it is how bad is it. I have a new Explorer ST. I would like to occasionally launch off the line. I do not want to do anything to hurt my new car. Will things break, wear out, etc. etc. if I do this. Thank you in advance!

All this time o thought launching was just flooring it. Had no idea there was a technique to it

Thank you, very well explained

Will holding the foot on the brake for too long, while the engine is working at high rpm damage the torque converter due to heat building up?

I have a feeling that just the fact that this video exists will mean the death knell for many of the "mom and dads" cars that are out there.

Are you going to show us or?

Have fun replacing your transmission if you do this.

Thanks!

Yeah man, it's like you got to use your gas as the clutch and gas . it's preeeeees down then let up and puuuushhh again, feeling the gears shift.

Does anyone think that anything bad might happen to a 2019 Subaru Impreza cuz I wanna try this.

how to change your engine and transmission out?... simply launch it blow the transmission and hope it cracks the input shaft from the engine and simply swap in a more powerful one

Now I need a new transmission, thanks

Well, I just tried this and now my car is broke....thanks Obama

Should i turn off traction control when doing this?

I've did a launch before in my 99 ranger that's automatic
transmission is still fine

Wait, I know a frs/BRZ has a torque converter, and because of that the auto is slower than the manual, why is it so much slower than the manual?

What if I just just release brake and absolutely slam the gas pedal through the pavement at the same time?

Awesome

hey is that the oregon gorge there?

Is this bad in a fwd?

I didnt really care about the math and all the scientific details. Just show me how its done

What about a Dual Clutch Transmission???

So I guess I been doing it wrong by putting it in Neutral, rev as high as I could and slam it into drive mode?

What if you held your rpm in neutral then switch to drive?

you mix the hard numbers and the real action... I love the auto launch disclamer, my car is still under warranty, so i will not try this at home, but i will buy a parachute, so i can be NHRA compliant ;) i love you.

you can borrow my versa it has cvt.... if the warranty is voided or the car destroyed, it is all in the name of science....

Thanks for your great videos, had a question. I think I'm understanding your explanation of torque multiplication compared to manual transmissions. My question is that when we dyno'd cars at the shop I worked at, manuals always made more low end torque than autos with same mods, which is wouldn't what I would expect now that I understand torque multiplication. Could you explain why?
