Its also ah hem quite handy if for example, you felt like trying to put a V10 S6 into a 4 wheel drift without ESP putting you back right again...

So I've heard..... :rolleyes: :D

:ROFL:
Nice one Ian
So did you managed or not?

Wow i had no idea that this could be done +++ .. so if the ESP is off single press what dose this do if in the snow for example because im sure it would spin all 4 wheels ... what will happen with esp and ASR off in snow as an example .. im not sure i understand the difference ... Blond moment :)

I had all four wheels spinning in the D2 outside my house with ESP switched on, because all four wheels lost traction equally the car believed it was in motion and nothing was wrong. I had to get out and dig the car out with shovel before it would move.

Er, hypethetically... Hells yeah....Easy with the V10 :D....+++

Simply put, ASR is Anti Skid Regulation, aka Traction control. If it thinks a wheel is spinning, it will apply brake and sort it out. With quattro to be honest, you dont see it much on tarmac, just snow / ice etc unless you have north of 400 horses and at least a morning dew... lol.

ESP is Electronic Stability Control, i.e. is the car going in the direction that the steering wheel is pointing and is it all nicely under control. If not, it backs off the power and inteferes to correct it. If you wanted to go sideways, lose the back or generally be a hooligan, you need to turn off ESP...... apparently.... :rolleyes:

Snow is tricky. As said, if all 4 wheels spin at the same rate, it is possible that ASR wont know anything is wrong, until one bites and then all hell breaks loose... +++

ESP in operation can be quite amazing.
I remember the first time I triggered it in my late-lamented PF S8, not long after I first got it, so about a dozen years ago.
I was pootling along, basking in the comfort, on a road I know well and arrived at a mini-roundabout with maybe a tad too much speed. :tuttut:

It was during the daytime, quiet, dry and sunny, no other traffic, and I suddenly realised as I was actually on the roundabout that I had intended to turn right (it's only a 3-way junction, but that's still 90 degrees) rather than go straight on (which was the next exit, no turn off to the left).

So I heaved on the wheel, expecting some sort of drama, and it just went round with a couple of twitches and a LOT of G-force to where I pointed it. And yes, the ESP light did flash!
I remember thinking at the time "bloody hell, that was impressive for a car of this size!"+++

*cough* or a big sootchucker...mmm torque :)
Been there.. done that..

Sure.... if you're happy to wait a few extra seconds for the fun to start... :p

Shh... or they'll all want one :)
