Aston Martin testing modified Vantage at the 'Ring

Aston Martin is on the verge of a renaissance that stands to be the biggest shift for the British automaker since it went independent in 2007 – if not since Ford took it over in the early 1990s. It's got a new chief executive, a new engine deal in place with Mercedes-AMG, a new platform under development and – if the new Lagonda sedan is anything to go by – maybe a new design direction in the works. And what do we have here? A test mule that could foreshadow one of the first new models of this new era.

Spied undergoing testing at the Nürburgring (where else), this prototype looks for the most part like the existing V12 Vantage S, but with what look to be even wider wheel arches. The question, then, is what those widened wells are there to accommodate, and the most likely conclusion would be that new Mercedes engine.

Aside from the lack of grille slats inside that trademark opening in the nose and the competition-spec alloys inset in those arches, there's not much else to go on. But that Aston is testing such a prototype at all is evidence enough that work is under way on something exciting, so watch this space.
