Traction control?

So I was out in an empty open road and decided to run my 720s. In normal mode. On third gear as it approached redline the rear starts to spin and drift sideways. I was like WTF. Seriously that episode makes me not trust the car anymore. Car just got out of service with 3,000 miles.
So guys please tell me, does this happen all the time? Never had any car do that in my life with TC on.

That is definitely not good behavior
I would think if you were wot, the shift would produce the car stepping out not as you approached the redline.a violent shift in track mode can definitely cause the car to step out especially when the ground is “cold” and the tires below well warmed.
Damp conditions also can contribute to this action.
But, I would lose my shit if it happened to me as redline in third gear.....you were going fast

What tires exactly?

Personally I always turn on active - and never run 'normal' or comfort powertrain unless you are only driving straight and want to save fuel. It makes the car too unresponsive to drive easily if you are going to use the power. 'Normal' or Comfort handling is OK, it just softens up the dampers.

Also check your settings - there's a menu point for the type of tires fitted. I have a feeling this has some effect on traction control settings. Choose the tire that is nearest to what you run.

Regrading pressures - if you are on standard P-Zeros (not the Corsa version) then you need to do two things:

1. increase warm pressure to about 32-33 PSI
2. buy better tires sooner rather than later.

I think without 'active on' the car defaults to sport/sport anyway - I don't really see the point of ever driving without active on and the aero active.

I drive most of the time in P: Sport and H: Comfort - but switch to H: Sport on the Autobahn.

Race/Race is best for smooth tracks.

I agree the tires were too cold. This is a serious car you have to be aware of conditions. You don't just get to smash it any time you want without consequences.
If you turn it to race mode it will tell you if the tires are warm or not. You don't have to keep it there it just gives you more information.

Good luck and be careful.

Go get a superbike, come back to 720S and read this joke:

Moishe has a problem, so like any good chassid, he goes to visit his Rebbe.
Moishe: Rebbe, my apartment is very crowded. Besides me and my wife, there are also my children and my mother-in-law. I don't have enough room! What should I do?
Rebbe: Bring a goat into the house and let him live with you.
Moishe: But Rebbe, there's no room for a goat.
Rebbe: Bring a goat in the house, I tell you!
In a month's time, Moishe returns to the Rebbe.
Moishe: Rebbe, things are much worse now. With the goat in the apartment there is no place to move.
Rebbe: So get rid of the goat!
The next day, Moishe returns to Rebbe smiling.
Moishe: Thank you, thank you Rebbe. All of the sudden, our apartment is huge.

Our cars are high powered lightweight RWD cars, dont forget that, 720hp alone on a heavy E63S, M5 or even 992TTS with 4x4 won't be the same. You have to be careful on the low grip surfaces (paint, dirty road, etc) especially when the tires are cold, I don't think there is anything wrong with the car, maybe get some better tires and warm them up a bit before pushing.

I don't understand what most of you guys are talking about regarding grip. Traction control is for controlling traction. That's like saying "oh yeah, you can't count on traction control in the rain". Then why does it exist?

Having said that, manufacturers can't seem to figure out how to make traction control (or stability control) that works, and it makes for scary times when it fails to do its job.

What Anthony Said above. You have to learn car control, which is no small task in a car with over 700 HP. Today's cars have so much power, it's important to learn car control, counter steer and other measures. It's worth taking a high performance driving class if you haven't.

Now, Traction Control is and still should be there for those "oh sh*t" moments. Personally, I think McLaren's TC is the best I've ever seen, and I've driven a good assortment of supercars. I think McLaren using race experience has the most well balanced and least intrusive system I've ever driven.
