Going on a group color tour this weekend and may have an opportunity to stop at a local drag strip with an opportunity to take my Z06 down the track. I have looked at the owners manual and don't see much info on the different modes (track, sport, touring etc).

I am wondering, if I get my nerve up, which would be the best mode to leave as many "Nanny's" on as possible for the additional assistance.

Also, should I jump on it right out of the hole or do something like 50% off the line with a gradual increase to full throttle down the track, or some variation of this?

Also, Also... Can anyone give a description of the difference between Track, Sport and Touring as far as the stability control functions that are on or off in these settings?

Thanks much.

I think a lot of starting line technique will depend on how prepped the track is. If well prepped you'll be able to very aggressive. If unprepped you're going to have finesse it. Much of the fun is figuring out what it takes to wrestle this beast off of the line.

In any case, while not designed for it this car is a BLAST to run down the quarter mile. Enjoy!

Here is a matrix that I found here on the forum that I saved since it was a great way to visualize the different modes.

M7 or A8?

A8, mash and go...

M7, feather the throttle and clutch off the line. Like a hard street start. You should be full throttle rather quickly, assuming a decent burnout...

Since you sound a little nervous, here's what I'd do.

- Put the car in D
- Put the mode in Sport
- When the last yellow light turns off, floor it

That's all you need to do, and the car will have ALL of it's nannies on. If it gets sideways at all, lift, don't try to save the run. If anything ever feels weird, gently lift and steer. But you'll effectively be driving straight down a two-lane highway.

I'd say that''s your lowest risk, safest way to try it out. With factory tires on a decent surface should be no riskier initially than a freeway onramp, so have fun!

With little or no drag racing experience I would suggest that you use the "launch control" feature. It tells you in the manual how to use it. Just go around the water box and don't do a burnout. If you do want to heat-up the tires that is going to make your staging prep more complicated. IE you have to turn TC off and then worry about getting it set back into a launch control setting. LC is fairly consistent, but an experienced racer can better its performance. But for those who dont have much experience it's a good option.
Please let us know how you do. You will have a great time. These cars are true super cars. They usually have a big crowd following so be prepared to answer a bunch of questions.

I did an autocross in July with my car and that is the first time I did any launches with it. Since I was instructing my two grandsons in autocrossing the car I always ran it in Sport 1 (Turn console **** to Track, push the center of the button twice and then use the **** to select Sport 1). This will turn off traction control and leave some stability control in place. When I drove the car I would move it to the start line, bring the revs up to ~ 2300 and when given the green flag let out the clutch. I had Hoosier R7s tires so the car would initially spin the tires slightly, followed by them grabbing as I was letting the clutch out and rolling onto the throttle. Within 40 to 50 feet I was wide open. From the outside it sort of looked like I was using Launch Control since the wheels were doing a similar spin and grip like you see launch control do but I didn't have the throttle wide open since I was starting on a down hill slope which required applying the brake to keep from rolling through the starting line. As soon as I took my foot off the brake I used it to bring the revs to 2300 before the car could move more than a few inches.

Here is a video showing the rpms going up close to 3K just as I let the clutch out.

As you can tell I wasn't getting an excessive slippage coming off the line, however, the Hoosiers probably gave me a little more grip than stock PSS tires. If you have the Sport Cup2s they will be closer in performance. Notice the car went where I steered it since the rear tires were gripping. Oh, by the way PTM was active which may have reduced slippage. PTM is great since once the tire gets traction you go.

I have an A8

I have an A8.
The overall message is...
Put in in D
Sport mode
Stomp it when the light turns green
Ease off is it gets squirmy.

Thanks all.

Not to confuse you but nobody has had success running their A8 trans Z by just putting it in regular sport mode without turning traction control off. You cars computer will just kill all power to the engine with traction control on as soon as it detects and spinning of the tires and you will embarass yourself with a terrible elapsed time (ET) if you keep ALL the nannines on. THerefore, you will want to put it in sport mode and hit the traction control button once quickly to take off traction control (but still keep active handling on to assist you if the car gets squirrelly).

Most have had success by doing what I reference above but but keeping it in touring mode (turn of traction control only) and then launch b/c the less stiff suspension probably allows the car to squat better in the rear upon launching quite possible leading to a better 60 foot time which ALWAYS Leads to a better Elapsed Time (E/T)!.

Thanks all!

I can only give advice if you have A8... if so do burnout in manual mode 1st,2nd gear shift back in drive.... tack it up 2000 rpm and stab and stear.... if the tracks good you should not have a problem pulling 1.65 60 ft or better that's what I did on stock mpss

Mopar Jimmy

What mode do you run in (TC and Active Handling both on)?

What's was your best et and mph with that great 60 foot times on stock tires?

Anthonys_Zo6

I was down in Florida at the time weather is a lot different from up north.. we did a track rental at pbir I made like 15 passes Tried every mode car seemed to run best in sport mode just traction off.. hit button one time... best I can get was 10.75 @129 1.65 60ft... down in Florida hot heat muggy humid

Mopar Jimmy

WOW, outstanding congrats, I'm jealous, just went today and could only muster a 11.20 at 124.9 in good air (500 DA)!

Anthonys_Zo6

thanks.. where you live? What was your short time? Try that method I told you if tracks good it will hook

Mopar Jimmy

I had only one GOOD 60 ft time out of 4 runs spun like chit on the other 3. That one good 60 foot time on NITTO drag radial was a 1.649 and yielded me my 11.20 but low mph for some strange reason 124.12 (thus costing me my 10 second time slip that I was very confident I was going to get).

This was run at Great Lakes Dragaway in Union Grove WI (South/ East WI) with GOOD Da of +500, on a picture perfect 57 degree sunny day. My theory is that I spun at 1/2 track a bit and active handling kicked in and killed my mph as the car seemed to short shift.

I did run in your EXACT MODE and could not hook up on that run (regular sport mode T/C off). I am PISSED off that I did not run the car with both TC and Stablity track off when I ran my good 60 foot time b/c that could have given me the extra mph (power) that I needed to go a 10.9x time slip, however, on a positive note the car did skate a bit at half track and maybe the stability trac saved my *** (I don't know), i do know I hate that cement wall right next to me and HATE more that my $85K dollar car is not INSURED on a race track.

I thought active handling was off if tc was off unless you're in track mode? So S mode with tc off also has AH off.

Mopar Jimmy

No. In regular sport mode if you just turn off traction control off by hitting the center console once real quick stabilitrac/active handling is still on. This is the same case when you are in touring, sport, or track mode. To turn off both Trac. control and stabiltrac/active handling in these mode press the center console button for about 6 or 7 second straight and then you will have turned both nanny features off.

Dfwz06

I tried just tapping the trac button today in S mode. Hit it in 2nd gear, and was all over the place. I never felt active handling kick in.

Good stuff
