The Audi A5 was unveiled at Geneva to much fanfare, and within 30 seconds of pictures hitting the net the elegant coupe was been surrounded by rumors. We knew the S5 was part of the package, but since the newest Audi had two doors, cabrio conjecture wasn't far behind. Perhaps the most anticipated A5 talked about is an RS version, which could include either the high-revving 420-hp 4.2L V8 found in the RS4, or the Lamborghini-sourced 5.2L V10 found in the S6 and S8.

The scribes over at World Car Fans point out that the RS version typically one-ups AMG and BMW M cars, and with a 480-hp CLK out there, the Gallardo V10 would make a nice trump card. We're inclined to agree with that hypothesis, since Audi already has the powerplant in the corporate parts bin, and there isn't much tuning necessary to get it back up to 500 HP. Audi has also shown just how serious it is about keeping a power edge against RWD competitors after it had the lug nuts to slap twin-turbochargers on the V10 destined for the RS6 Avant. Either way, Audi is no longer interested in being an also-ran in the luxury market, and big-horsepower coupes will only make the brand that much more appealing to enthusiasts.
