How many Corvettes do you currently, or have you owned? How many other GM performance vehicles do you currently, or have you owned?

1. They leave the ABS always on
As does the Corvette.

2. In order for the ABS to work properly they have to leave the traction control on to "monitor" road condition but " unobtrusively" (according to them)
And that's not what the Corvette does. The ABS is tied into the brakes via the input (ie, the pedal) and the wheel speed sensors (they're in the hubs).

3."Unobtrusive" means not intervening with driver input "except" where said intervention is to facilitate the proper operation of the ABS
If they're using the TCS or stability control systems in their respective vehicles to help with ABS, that's all well and good. It's not what the Corvette does.

Lawsuits on Euro car companies are almost non existent and on US car companies are prevalent
Not when it comes to ABS and stability control systems, they aren't. You're starting to pull things out of thin air (or other not-very-nice places).

This is how I came to my LOGICAL conclusion
Your logical conclusion is completely incorrect, full of holes the size of a bus, and based purely on knowledge you only think you have.

All that with a little smirk on their faces and when pressed they always admit its the company "brass" that has the final say on "safety" ( you have to admit this was brilliant)

Lawsuits on Euro car companies are almost non existent and on US car companies are prevalent ..So answer this do you think the CEOs at GM are going to leave themselves in actionable legal positions by not doing what their counterparts do and exposing their customers to harm or partake in the same "ruse" of "Unobtrusive" TC and full ABS ?
I don't agree with the "ruse" but fully understand it ...This is how I came to my LOGICAL conclusion
Funny... the C4's ABS works just fine without any Traction control....
GM isn't Ferrari. They actually have a brain when they design their cars. ABS is monitored through wheel speed sensors, mounted in the hubs. This sends signals back to the ABS controller, which also monitors fluid pressures, and pedal input. The ABS controller then pulsates the brake activation accordingly so that the wheel will be able to maintain traction while continuing to make steering input in the wheel during an emergency, or deep braking situation. It has nothing NOTHING to do with the TCS system. TCS sensors are mounted in the diff IIRC. I know for a fact that they aren't the same sensors that are used in the ABS. And never have been since it's introduction to pretty much any GM performance car.

If you mean the ELSD that's another kettle of fish. And Gm still does THAT differently to everyone else. Rather than working through brake side bias, and the TCS system like everyone else, it controls the actual state of lock or open ratio of the Diff.
If you want to go full on ***** out, you can.

Given the Stingray and the C7 Z06, I'm guessing there are going to be a bunch of new Corvette owners that have never owned or considered owning one. Which is good. It's likely that a lot of these new folks have purchased performance cars from other manufacturers, and are used to the way those manufacturers do certain things. Once of the big differences is the stability and traction control systems on the Corvette.

GM's been putting TCS on the Corvettes (and F-bodies, and other performance cars) since the very early 90s, if not even earlier. Historically, TCS has just had a simple "On" and "Off" setting. In the "Off" setting: it was really and truly off. If you wanted to light the rear tires up or wipe out, you could do it with ease.

During the mid-90s, GM developed their Stabilitrak system. On the Corvette it was called "Active Handling", but it was the same system as used on their other cars. It didn't appear on the Corvette until mid-MY '98. It had 3 modes: On, Comp Mode, and Off. Like the TCS before it: when set to "Off" it was: Off! If you wanted to spin the car, it would stay out of the way and let you.

Trust me: I know this from first hand experience!

C6's Stabilitrak was better polished to include an extra mode, but it still includes an "Off". The PTM on the C6 ZR1 and later C6s also has an "Off" setting that will let you put the car right into the weeds if you want to.

C7's system is no different, it's just full of more polish and more inputs (wheel temps, for instance). But if you want it turned off, you can do it.

The other vociferous participant in this thread isn't speaking from a position of experience with Corvettes or any other GM performance vehicle. If he were, he'd know full well that what he's writing isn't true. Neither of us are presenting opinions (though I did accidentally say he was "opining away"). We're presenting facts. It's just that one of us knows a bunch of facts that aren't true.

Yes. That is exactly what I believe.

If I have learned anything about my CTS-V, it is don't turn-off the TCS until the tires are THOROUGHLY warmed up (just trust me here).

Even then it is dangerous. When I first bought my 08Z06, I went to an abandoned road and punched it. It went straight as an arrow with limited wheel spin. I turned all the nannies off and punched it again. The next thing I knew, I was sideways. I never turned everything off again, just traction control.

I guess TC works...but sometimes you don't want it to work...99% of the time I will leave it on, but when a certain individual down the street is watching me leave "light um up"...JVP i'm satisified with your responses, man this car is going to be fun!

So now I'll offer a suggestion and opinion. If you really want to get under this person's skin, ignore him and drive away. Lighting your tires up really is a childish, stupid, and expensive thing to do.

If you just shut traction control off, you can smoke the tires. Leave everything else on.

I never understood why guys think it is manly to turn off the safety features - when driving on the road.

I get on a track.

But, on the road - it isn't your place to pretend you are a professional driver. The safety features keep you alive and prevent you from killing a family.

I have the A6 in mine and I leave it in auto during hard launches.
A little trick I learned was to turn off the TCS after the first 10 feet or so (while the tires hook-up).
It's easy to do as the On/Off button is on the front of the steering wheel and I can hit it with my left thumb while keeping both hands on the wheel.
It makes for a smokey 50 yards or so with pretty good control.

The whole idea of having a car like the Z06 is to have as much fun as you can (without killing yourself, of course).
