I've autocrossed a Golf R, what an amazing car to launch. You get multiple launches and once you preset everything all you need to do is hold the brake pedal and your foot on the gas and it's on.
It lets you pick the rpm with your right foot, let go the brakes and it launches at your desired rpm.

Really easy, it feels almost as if you're loading the DCT at whatever RPM you chose using your right foot on the gas.

None of that driving 1.5 mile or so before you could use the launch control again.

Also you could launch at as low as 1,500 rpm if you want to. BMW minimum RPM for launch control can be too high in some surfaces and on older tires.

I plan on getting an awd G82, thanks!

Thanks

This 911 turbo has over 500hp and over 500 lbft of torque. Watch this guy do 50 launches in a row.

The unlimited "smokey burnout" on the F8X right now is pretty hard on the rear diff, half shafts, probably worst than a proper launch.

Do not compare a 911 turbo to a Golf R, just don't.

Where in the hell did you get the idea that i was comparing a Golf R to a 911 turbo?

He was addressing the claim that repeated launches is prohibited by power and torque which it clearly isn't as example by other more power cars like 911 turbo and I would add tuned rs3 to that list.

Of course that's because they have a dct and the g80 will have an zf8 Speed auto with hopefully m-xdrive.

Here's the link to the article about the actually properly designed PDK in the turbo:

https://www.roadandtrack.com/new-car...-65-7-roa0314/

"There is no limit." That's what Porsche chief propeller-head Wolfgang Hatz said when someone asked him how many violent, Bugatti-quick launches the 911 Turbo S can perform before grenading itself.

I autocross my M cars, you get 6 runs somtimes back to back. No different than having a manual with back to back launches at a desired rpm.

The Golf R let's you pick the RPM you want to launch at every time, that's very useful! If the surface has good grip you can launch at 3,000 rpm. Sometimes 1,800 rpm gives minimal wheel spin.

I have autocrossed for years in 5 different states and have never once met a driver who uses launch control out of the start box. Unless you're at a drag strip, launch control is pointless, and even then it's a gimmick at best IMO. Just brake boost the car, no different than launch control if that's what you really want.

Will the ECU allow it? As far as I know, my M3 will still cut power when the brake is held and the engine is rev'd up higher than some relatively low RPM.

Furthermore, no braking should be necessary to launch a car. It just adds needless stress to those components. Launch Control allows you to disconnect the engine from the rest of the drive train, rev it up, and then reconnect quickly similar to how you would with a manual transmission.

As long as we can agree there is at least one legitimate use for that type of activity (and I think we all do), the Launch Control feature has merit. Now whether it is important enough to be as robust as what Porsche or other manufactures may provide is an open question, but I don't see why someone shouldn't express the desire for that to be the case.

I have done it with all the nannies off IIRC, but I could be mistaken. I agree there is at least one arguably valid use (drag racing) but other than that, it's really pointless IMO. Granted, everything else you said in your post is valid however, re development etc.

I like to qualify my posts to say it's my opinion. I get that he wants to voice his want/need and I never meant to admonish him for that expression, but then I should be able to voice my opinion as to why I think that want/need is no different than wanting a third cup holder. IMO it's a gimmick other than for the very few of us that may actually go drag race the car. But that's just it, it's my opinion.

I would be very surprised if you can get any sort of acceptable results using this method (brake torquing). If you can, please report back because that would be a new discovery and big news IMHO.

That's fair - you are entitled to your opinion.

I will say that I doubt you will have a very large percentage of the enthusiast populace agreeing that Launch Control is merely a gimmick. Although few use it regularly, it is a fun thing to use on occasion when out hooning around in the car for enjoyment.

Also, to the extent that 0-60 times or other metrics for acceleration are important, so too is getting a clean launch. While LC does not guarantee the best launch, it does make for fairly consistent and repeatable results.

I don't really care too much about 0-60 times or track times. But launch control can be pretty fun. You've gotta launch your car every once in a while when you have the opportunity.

I'm still buying the manual though.

Exactly my experience. Every autocross course I've done has had two hard 90 degree turns right before the timing start light specifically to prevent people from hard launches right at the start. You do a hard launch at an autocross course and you're going to be on the brakes before you've even started your run.

At the Nationals and most SCCA clubs follow the 90 degree turn but some SCCA and most NASA clubs dont follow it.

That's exactly how i launched the DCT Golf R, it works great.

The M4 cuts the power when you try to do that.

Good point. It's definitely not possible to brake boost a DCT M, but hey, it's the interwebz...

I guess now that they're going to a slush box, launch control wont be needed. You could just launch it like a Steptronic.

BMW still includes Launch Control with their AT equipped vehicles, including the new F90 M5. I don’t know any details about it though, including how it compares to launching the car without it.

They can't really say it's a launch control if it creeps!
