Opel has been kind enough to release a teaser image (seen above) of their upsoming Geneva Concept, but they have released absolutely no information! Here is what we have found out. It will be the new Opel Vectra / Vauxhall Insignia / Saturn Aura. Opel is aiming to have these three models share the same platform (currently the Aura uses an extended Epsilon platform), and so this concept will be what the MY2011 cars will look like somewhat anyways. First car to be built on the new Epsilon platform, the Aura Wagon. See more spy photos of the Vectra test mule after the jump. Special thanks to Guido for the tip and photos!
