Audi could have a 450 horsepower trick up its sleeve.

An oddity spotted at a Virginia Cars & Coffee has spark a very intriguing question - is Audi planning on selling a version of its RS 4 Avant in the United States?

The internet rumor mill was set abuzz over the weekend after a fan of the enthusiast site QuattroWorld posted pictures of a 2013 Audi RS 4 Avant at a Cars & Coffee event near Audi's U.S. headquarters in Herndon, Virginia. The 2013 Audi RS 4 Avant is currently available in Europe but has never been sold on these shores.

The car in question was reportedly a German-spec model loaded to the gills with every option, including massive carbon ceramic disc brakes. The RS 4 Avant even sported a "You just got beat by a wagon" rear window sticker.

But the real question remains, why did Audi chose to display the RS 4 Avant at the event in the first place?

Although we don't have any concrete answers at this time, it could be Audi's first attempt to gauge market demand for a high-performance - and high-dollar-- performance wagon. The local Cars & Coffee would be an easy and logical place to start to test the waters for a vehicle like the RS 4 Avant.

The again, Audi could just be throwing its hometown crowd a bone by showing up in the only RS 4 Avant currently in the country.

Until Audi indicates differently we'll chalk it up to the latter, but we certainly wouldn't mind seeing a 450 horsepower wagon in U.S. showrooms.
