It is well documented that the 8 speed shifts much faster on it's own than it does using the paddle shifters. In auto mode, the computer can anticipate the shift. In paddle shift mode, it can't react until you actually tell it to.

Yeah I was referring to the manual mode that shifted slowly. Auto mode shifts fantastically.

 

[Jerry U]

Hmmmm....I have a 2016 auto. I've never disabled the traction control, and I can break the tires loose at will from a dead stop. It'll also lose traction during wide open throttle shift from 1-2.

That being said, I'm not talking "smoky burnout". I'm also of the viewpoint that losing traction in a sports car is a bad thing. If you want smoky burnout buy a Dodge Demon.

Of course, I'm in the minority that thinks the A8 shifts plenty quick (if in track or sport mode and driven aggressively) so take my observations accordingly. I just don't understand the sluggish shift comments... slower than a DCT? Sure. Slower than a Tremec 7 speed? No freaking way.

I agree. I thought “burning rubber” was “cool” when I was 17 & 18. Was fun with my ‘41 Opera Coupe I stuffed in an Olds engine! For the last 56 years I have thought it was stupid! :unconscious:

I find the same, in Sport I get a chirp on the 1st to 2nd shift with my M7 and the nannies activated. Heck I work hard not to burn rubber with the 8.2 Liter engine in my Street Rod when doing 0 to 60 mph runs. When it’s warm I get two black marks from the 16.5 section width Mickey Thompsons on the tubbed chassis with a 4 bar link rear! Engine is set back and that heavy 9” Ford rear provides 53% weight on the rear wheels.

Maybe the rental agency detuned it so that it doesn't have optimal performance in case renters get crazy.

They may have already saved you from ending up like the red one in meyerweb's post!

 

[Liner Boy]

No issues for me breaking the tires loose from a standing start. In sport mode no less. I have an A8.

 

[Ateupjoe]

Me either. No problem M7

 

[STINGmole]

Also, maybe this warrants a separate thread but there was the engine made a defrosting noise (similar to how your fridge sounds when it shuts off) when I switched from track to eco mode. Is this normal?

I think that's the sigh of relief the engine makes after surviving a hard day of rental abuse. Totally normal.

Let this be a lesson to everyone as to why we shouldn't buy rental fleet vehicles. Also, I'm not sure it warrants another thread.

M7 - There is this one uphill stretch going home I’m in 2nd and drop the throttle to the floor and I can feel the tires beak loose, no noise or burning but the rear end drifts a bit, then I’m at my turn. ? [emoji12] [emoji33]

I don't like to take it that far but if its an uphill pull its fun to run the power.

 

[Mobius]

Since others have chimed in, it's easy with the M7, by modulatin' the clutch and throttle (TC off, of course).

Sounds like some of you are being hard on this guy. I track my Z51 and appreciate traction when I need it, but I have to admit that I also love to spin or chirp the tires on occasion and also frankly like getting a little sideways around corners when nobody is around. So let’s all enjoy our vettes how we like. Back to the original question there are a few steps to let it all hang out. Put her in Sport or Track mode then click the traction control button 1-2 times to turn off the nannies. Then get on it! I am sure you will get the results you are looking for. And yes, maybe the rental does not allow you to disable the nannies.

 

[Apollo355]

Haha hey guys look, I appreciate all your concerns about my safety and all - but I'm not some idiotic 18yr old who doesn't know what he's doing. I've driven very fast cars on tracks before including lambos, ferraris and mclarens. So I'm no newbie when it comes to power sliding and handling corners.

The reason I'm only settling for a Corvette and not anything more expensive is because currently that is all my wallet allows me to. But if it cannot do a simple basic task of breaking tires loose, then that would have been a deal breaker for me.

BUT, I conclude that it is the rental agency that is the culprit here. They detuned it so that the car isn't able to to do this even with the traction control off. Because at 460 ft/torque, they should have let loose with the foot pressure I applied.

So, now I will start shopping for one with ease of mind.

Thanks Petesar1, I'm now 99% convinced that it's the rental agency. Once they sell that car off their fleet, it would probably return to its default performance and will probably do it.

You can't afford what you want so your "only settling for a Corvette". Sorry your "wallet" won't allow you to get what you want. How you gonna shop with "ease of mind" if you don't have the money to get what you want? The rental agency isn't the "culprit here". You are. Not sure your honest.

Yep. Nothing like coming on a forum and telling folks that you are only "settling."

Kind of like going to the father of the girl you want to marry, and saying "I couldn't find anything better." Not going to end well.

 

[Jerry U]

Yes, a bigger horsepower car can break its tires loose more quickly.... And/or perhaps the Hellcat is under-tired, and our Corvettes have the right tires for our suspension and power.

Regarding our Corvettes, disabling traction and stability controls on a vehicle you are brand new too, is not something I would do, nor something I would recommend. It is however, a ticket for crashing into the car next to you or ending up into a ditch.

Agree! Actually big tires on a high powered car can be more dangerous!

On my street rod, with it's set back 8.2 liter engine, 16.5 inch section width (~420) Mickey Thomson sticky tires, 4 bar link suspension, 53% of its weight in the rear but only Positraction, can be scary! On a 0 to 60 run if one tire breaks loose due to a pavement issue etc the other large tire has so much grip it powers the car very quickly to the opposite side. You have about 1/2 second to lift or you're in a ditch!

I'm reminded of that when I watch ProStock cars in a drag race on TV. Even when that happens to Pro's, the car can turn 90 degrees and they may slam into the concrete barrier!

A number of video's where a Z06 does the same and runs off the road or worse! Can always have enough power to break most tires loose! Even my Grand Sport with less power than a Z06 is tire limited off the line!

I never had a reason to turn off the nannies in my 2014 C7. Drove with it set at Sport and a bit too much throttle when merging into highway traffic had the rear step out slightly. When below 45 F used Weather Mode so they caught it quicker in that same situation that I face every day leaving the street where I live merging onto a 4 lane divided highway!

Agree, if you have the skill and know the car! Had a great time with my modified Corvair as the rear end "started" to come around when going too fast into a turn. I was ready with reverse lock! Also drove my Dodge Colt Turbo around corners modulating the emergency brake, holding in button to slide the rear around to match the understeering front. That was in a safe area.

But would not do that with a high powered rental car until I understand how it will react. Reminds me of the folks who rented Shelby Mustangs from Hertz and brought then to a track! :welcoming:

Haha I heard those stories too, and that would be against rental policy to track it. As for me, I did it on an empty stretch of road.

Lamborghini Centenario is what I want, but I had to settle for a Corvette. Sorry if that offends you.

Apollo, get whatever car pleases you, be it a Corvette, Hellcat, or other. Regarding your desire for burnouts, you're an adult, do as you please but be cautious - any of these cars can bite you unexpectedly at any time, especially with the nannies all turned off. Hundreds if not thousands of YouTube videos will attest to that, and I bet every fail started with "I know what I'm doing".

This kind of activity is not for me, frequent tire replacement is not in my budget, but I do have a couple of thoughts: consider the manual tranny as it will be way easier to light up the tires, and save you the cost of a set as well. On an auto tranny, there are 3 levels of traction control in track mode - you actually have to hit the off button 3 times to get everything turned completely off. Good luck, and I hope never to see a news report about you in the future!
