Audi in terms of AWD is high-end! My father borrowed me his car couple of days ago, I'm talking about a A6 2008 3.0 tdi quattro. I approached an extremely tight corner at around 110 km/h (trust me the corner was very tight usually 80 km/h is more than enough to lose control) and the car when started to slide away towards the other cars from the opposite way, the car simply kept its line and track.
I would have been seriously injured or dead if I had driven an FWD or RWD in that moment. Amazing machine! No wonder why their motto is "We build cars! " I would say " We build cars not toys.." You can entrust yourself in their outstanding systems especially when it comes to quattro.
