Is this activated after a service, I can't get it work?

Bear in mind too that US spec cars are slower than (lighter) Euro spec cars.

I don't see any reason why having the car serviced should render LC unavailable. It's a factory feature. If you look at the manual, there are a couple of conditions in order for it to engage, such as keeping the steering wheel straight. Maybe hard in Scotland (with all those wonderful curvy roads).

Must be me then mate I'll keep trying, thanks

I somewhat unintentionally did it recently. I tried a few times, but was afraid to mash the accelerator with the brake depressed...the sound isn't pleasant. When I got it to work, it was due to intending to perform a slight brake boost and then just launch, but I actually ended up pushing the gas too quick to the kick-down before I left off the brake, and it activated LC.

So along with having driven it for some distance to let it warm up (~6 miles), turning off traction, and leaving it in Sport Shift mode...you have to quickly push the accelerator down to the kick-down to activate and then release the brake within 3 seconds. Be prepared for some hard shifts.

Does 0 to 60 really matter that much. Just got the I8 and had my son in the car. When we did Lc he thought it was faster then my r8 v10, which I know it isn't. To be honest it's quick enough and has a super smooth silky feel to it. His words were it feels like a jet engine taking off. The electric motor gives it that huge torque feel.

Go buy a hellcat for 0 to 60 runs. It's an interesting car that I DD to NYC twice this week and thought it was great. Something I would never have done in r8. Also got 38 mpg to boot. Not a bad deal.

Love the super stiff chassis from carbon fiber.

Agree completely. As if life was made up of drag races ...

A Hellcat? Maybe on a prepped 1/4 mile track with slicks and VHT. But on street tires off the line it just spins. RWD front engine too much torque poor chassis.

In the real world, if you want to destroy any car off the line, there is no quicker car with street tires than the PDK 997.2 and 991 Turbo S when launch control is enabled. Here's a simple bolt on 997.2 vs Porsche 918, boosted Lambos, drag bikes, built GTRs, etc on an airstrip which is the same as unprepped "street" conditions using LC:

Nothing stock (and few modded cars) beats a 918. An investor of mine had his tested by a pro driver and I've seen the vbox times. It's insane. It did 4.72 seconds to 100 mph......

My 991 Turbo S when stock launched hard. Almost as hard as my bolt on 997.2 in the video. Yes the 918 will out launch both on a drag strip perfectly prepped surface. But on the street I believe based races against the 918 that the 911 has a huge advantage with all the engine/drivetrain weight over the rear tires. And on a road surface with all the imperfections, rocks, oil, and other crap that accumulates, the ability for any car -except the 911- to launch is impaired.

Maybe U didn't see the vid there are two races against a 918.

Sorry to go OT. I actually don't care about going fast in the i8. My perspective on this car has changed dramatically. I actually enjoy driving it slow.

[Jo-Sta07]

I'm not going to argue the 911 TTS ability to launch on the road as I know it's spectacular. I'm just stating the times I personally saw from the 918 WP test. 0-60 mph in 2.31 seconds, 0-100 mph in 4.72 seconds. 0-150 mph in 10.02 seconds. Crazy stuff.

[Jo-Sta07]

Actual launch control question. I tried it for the first time today. I completely disengaged TC, put the car in manual shift. Stepped in the brake and accelerator and then lifted the brake. It def launched however it felt like car was lurching forward. Does the car sense launch control and engage it? Does something happen on the screen showing launch control engaged (like in many other cars)? None of that happened. Did I miss a step?

Launch control comes up on the hud display if you did it right

Can you tell what step I messed up from my post?

You can't completely disengage TC, you have to just tap the button and disable DSC. And you can't be in Manual, you have to be in Sport mode.

What he said

[Jo-Sta07]

Thank you both. Unfortunately I may have to wait until spring to try it again as the weather in Pittsburgh looks like it finally turned into fall.

For those that have done it, two questions:

Are the shifts harder? I know it's a lot of stress and under full load, but just curious if it's significantly more harsh for other folks.

Do you break loose on the 1-2 shift a little? The couple times I tried, it did. I'm hoping the 9/10 wheel setup will give it the grip it needs.

[Taxdr1965]

It shifts some what harder but not excessive. On the 1-2 shift the tires give a slight chirp as they break traction for a second. I think that's pretty cool

Ok so I tried it a bunch of times yesterday.

The bad news is that for me it comes on only once in maybe four or five tries. Maybe there is a cool down requirement so you can't keep launching.

Technique is like others said. Sport Mode with one quick press of the DSC button to engage sport traction. Hold down brake while at the same time press throttle to the floor to engage the kick down button and release brake. The brake-throttle action needs to be carried out in a quick fluid flow.

First gear chirps but it doesn't chirp on the 1-2 shift. What is interesting is that the car shifts at only 5,000 rpm on the 1-2 shift. Obviously because that's the fastest way to drive it. Anything over 5,000 rpm is painfully slow in this car.

I had the vbox in the car but the data is probably not great because i did my launches around my house and there are no level streets anywhere. Generally without LC my 0-60s were mid 4's and the couple times LC was engaged it was 4.1. Once it was 3.8 but pretty sure it was downhill a few degrees so not a good run. I need to try this again on a flat surface.

[sandrofelisio]

I tried many times but no way to engage LC...

Which is the step by step guide?

Can someone make a video to explain how to do it?

I still can't get launch control to activate. Do I have to press the brake really hard? I'm missing something.
