Audi RS7: This Is It  Now here's a bit of unexpected test-car
porn. Quattro World readers caught an apparent Audi RS7 test
vehicle in Las Vegas, clad in stealthy matte black and powered
by the same 4.0-liter TFSI V8 as the new Bentley Continental GT.
The new, biturbo powerplant is expected to produce upward of 550
hp, making the RS7 a bona-fide AMG beater.  Look closely in the
photo above (and in the photo below), and you'll see the RS7's
co-tester. If you dream really hard, it might just be the US-
elusive RS6 Avant being prepped for this side of the Atlantic.

Avant. Or, as it's pronounced around these parts, the "do
want."]
