It has all of that, which makes for a relaxing motorway cruiser (which is why I bought mine). But it also has: No feel at all in the steering wheel - you know when you lose grip because the power cuts as TC kicks in, or you get a fairly sudden lurch in direction as the electronic 'diff' brakes a wheel. No feel in the brakes - spongy would be fairly accurate. Again, you only know you've approached the limit when the electronic aids kick in. The throttle response is also typical VAG turbo diesel - smooth is one word, but unresponsive is another, it's not a nice linear response to your foot, instead you move your foot and it smoothly catches up with you, which means that gear changing takes longer than it should otherwise and you don't have the fine control over the throttle that you do on more linear turbo-diesels.
So yes, it's very refined. But even my 10yr old Astra DTI had more driver feel and control, and in uncertain grip conditions I would actually prefer it to the Audi, as it behaves predictably rather than a computer interfering without advanced notice.
Oddly I only find it understeers under power - there's too much torque for the front wheels to do accelerating and turning at the same time
On roundabouts the ESP actually seems to work really well, tucking the nose in very nicely without you feeling it do much. I had a shock when the courtesy golf understeered horribly on my first roundabout
So for my current driving and back condition, the Audi is perfect. It feels and behaves like a big car, and the driver is very detached from what's going on with the wheels, which makes for a very relaxing journey. But I'd be the first to agree it's very dull to drive. The power is the only thing that's grin-worthy.
