We just got the official Audi press release for the Frankfurt Auto Show, which like all the automakers pre-show releases reads like they're teasing us with a tease of the press conference. Meaning that they're cryptic and although in this case we're told Audi's world premiering two new — somethings — they're not telling us what they are. Now, we know one of them's the new Audi A4, which we've already seen revealed on the interwebs. But what's the other one? We're hearing from a source who heard it from a source at Audi of America that it'll be the new Audi RS6 that's rumored to be running with 600 horses. We guess we'll find out in person on Tuesday, September 11th. You on the other hand, will be able to find out by keeping your peepers wide open here.
