Great car for those who entertain or drive people around a lot. The V10 is very gutsy and has great pick-up, although it feels very restricted. The car becomes more lively in second gear and seems to accelerate with a ferociousness once it gets above ~5200rpms. The car is very heavy (my guess is about 4200lbs unladen) and can be felt when pushing the car hard, both in braking and turning. Once again Audi's Quattro is very confidence inspiring, and their 40:60 split helps dial out some understeer, although it still can be provoked easily. The interior is where this car really shines, though. With bucket seats that give great support, and look great, your ass wont be moving at all once you go into the corners. Audi has also used neat little touches to the interior for at night. Such as lights that dimly light-up the other arm rests. Its the little touches like the aforementioned that helps keep Audi near the top.

This is the best car i've ever driven. Period.

Great engine and superb build quality. I have owned many German luxury sedans but this is easily the best one I have owned yet. The Lamborghini sourced V-10 gives the thrill of an Italian supercar with the reliability of a German built sedan. Very precise handling.

I love this car!!! Gets many compliments, very fun to drive, very safe to drive. The V10 has a ton of torque, the car is about 5000 lbs so it is a very very sturdy car. Plenty of room for 5 adults comfortably.

Coming for a smaller but still powerful 4.2 S4, even if still AVANT version, I find this one being more roomy inside and more powerful in within... It's quite difficult to keep calm so many power horses...
