These are the first photos of the new Audi A7 on U.S. soil. The new four door sedan, set to compete with the Mercedes CLS, is expected to be revealed later this year at the Frankfurt Auto Show. Colorado, having some of the highest paved roads in the world, provides a perfect spot for high altitude testing of new vehicles. It's expected that this mule will proceed onto further hot weather testing in Death Valley later this month. Details on performance or engine options are still limited, but we're keeping our fingers crossed for the first diesel four-door coupe.

It was in November of last year that spy shots leaked to the web with the car in full production form. To see those photos, click here.
