Here are a few very nice photoshops of the 2009 RS5 made by Quinty. The RS5 is supposed to be launched this autumn at the Frankfurt Motor Show.
Rumors say it will be powered by Lamborghini 5.2 liter V10 engine that produces 500 horsepower in the Gallardo. Audi will fit the RS5 with Quattro all-wheel-drive. The body will take on a much more aggressive look than the S5 along with a sportier interior.
