Check out this awesome car. I love Audis, always have, and I can only wish I can own one of these one day. Unfortunately with a price tag of $130,000 or more, this is way beyond reach from us mere mortals.
Here are a couple videos.
This one has a touch of promotional flare, and you don't get to see it much. It was made when the Audi was brought to NY city last year.
A picture slideshow and video showing a lot of cool stuff about the car.
This is a really well done video by Winding Road Magazine. The engine sounds so mean.
Here's a great review of the car with tons of pictures and more information.
