No you haven't...you're a teenager who thinks oversteering is akin to drifting. You have no idea what you're talking about when it comes to handling dynamics and you make that more and more clear every time you make a statement.
So I'll slip outside in a bit, Spin out my touareg in the snow for you (I'll barely touch the steering wheel) and if you don't have 100 in my paypal account, I'll ban you from this site for trolling.
I'm 33 years old. I learned my handling dynamics on a track in my 911 - one that has no airbags, no power steering, no ABS. Just a gas pedal, a steering wheel, and a gearbox. Where did you learn your proper driving technique? There is a giant difference between inducing oversteer for the sake of having fun, and chassis dynamics inducing oversteer for you in specific instances. When people (outside of this forum) talk about whether a car oversteers or understeers, they're not going out to a wet lawn or snowy parking lot to see if they can get the back end to come around. They're exiting the apex on a track in WOT and seeing what happens. They're measuring that on a 300 ft skid pad with even throttle inputs to see which end looses traction first. Somehow - this is what is common knowledge in just about every auto arena outside this forum. But, coming here and people seem to think this car oversteers easily, like it's an S2000. If you want to know what easy oversteer feels like, that's the car to drive.
If you think oversteering in the snow means the same thing as oversteer as a result of chassis setup - you should ban yourself from this site.
Here is some light reading for you. Nowhere in this book, or any book, or any auto engineering circle will you find people out spinning their cars in the snow to see if the chassis is setup correctly. They might use snow, rain, dirt roads, etc to calibrate the ESP, but they're not adjusting sway bar sizes and spring rates because the back end comes around easily in the snow.

I love the treg. It has near perfect weight distribution and a super stiff chassis. Combine that with a well dialed damper setup, and it feels really planted at any speed. Aside from the overly boosted and zero feedback steering, I would say it's a marvel that this car handles as good as it does. But, it has no LSD diff in the rear, soft sways (you could put stiffer ones on, but that would detract from off-road comfort), 50/50 power distribution, not enough rubber, not enough power, and it weighs 5500 lbs. The cayenne turbo has 40/60 power distribution, stiffer sways, more rubber, and this results in almost twice the power at the rear axle. Have you driven one? It honestly defies physics, and you need to be brave to get it to properly oversteer at the track. Even in an autocross situation, it's hard to get it to oversteer. Ever done one of those? Most of the cayenne guys would say the chassis understeers, and people have updated sways to try and dial that out a bit. The only real way to really get it setup is to change out the air suspension for coils so you can dial in the spring rates and damper setups (which some have done).
Here is a vid of a B5 S4 OG (Cole) auto crossing his cayenne out here in Colorado. Basically a stock suspension setup. What do you see here? Understeer. At no point does the back end rotate. And, you definitely want some rotation when auto crossing. There is a reason that most high performance AWD cars have more rear power bias than 40/60, and that's because it's really really hard to not have a car understeer when the front is tugging just as hard as the back. Look at how much tech the GTR has in order to make that AWD monster have almost perfect handling characteristics.
If your touareg oversteers, that's not because the touareg itself is setup for oversteer, that's because of the driver. If you're trying to get it to oversteer - then good job. You've accomplished it. If you're not trying to get it to oversteer, but it does (exiting a corner or carrying speed through a corner without braking or accelerating), then that's because of poor driving technique. When you drive something this heavy, you need to have some serious fines in your braking and turn-in technique because you're shifting around so much mass. You can't just jerk it into a corner like you could a lightweight car. It needs to be buttery smooth turn in. If you turn in real fast, the back end feels like it's stepping out, but it just gets back in line after the weight transfer settle down. I've *never* exited a corner, went WOT, and felt the back end come around. You can easily use that weight transfer to your advantage if you want it to oversteer, but if you drive it like it was meant to be driven, and what would result in the fastest line, and it's going to understeer.
I'm done. When the moderator starts making this personal by incorrectly speculating on my age - I know I'm having the wrong conversation with the wrong group of people.
