The Aston Martin Vantage RS was caught testing on some of the winding roads at the infamous Stelvio Pass in the Italian Alps. We originally saw this car as the V12 Vantage RS concept at the Geneva Auto Salon in March.

The production version will be limited to only a few units, and from spy shots, it looks it will stay fateful the concept. The Vantage RS will be powered by a V12 engine that will deliver 600 hp and will debut in early 2009.
