Check out spy photos of the new Audi A7 during testing in Porto, Portugal. The story inside.

A sharp-eyed car fan managed to snap a few photos of the new Audi A7 on the road in Porto, Portugal.  The heavily covered-up car was spotted in the city center, showing rear LEDs, and some basic design language tied to the Audi Sportback concept from the 2009 Detroit motor show.

The four-door coupe has similar lines at the roofline and rear as the concept, and side window shape apppears to have been maintained.  It is un clear if the extra glass after the rear side window will still be in place, or if it is simply camouflaged.  Side sculpting looks similar, but toned-down.

Audi is expected to debut the car during Auto Salon Moscow in August.  The Audi A7 should be released in Europe soon after, with a North American release in 2011.

Head over to the Portuguese website Turbo to see all three photos, snapped by Nuno Mansilha.
