Aston Martin will launch six models over the next few years, most of them evolutionary successors to the existing line-up. Our spy photographers spotted a possible successor to the DB9 undergoing testing. You can spot the new model sporting traditional Aston Martin styling; it borrows elements of the Rapide such as the new headlights and the bumper-mounted number plate.Technical details are sketchy, though the new model will be developed under the codename Project VH500. It remains to be seen whether the British automaker will continue with the DB9 name, or skip to DB10 or DB11. The successor to the DB9 will reportedly reach showrooms in 2013.Check out our gallery!
