It's no great secret that the European Union's patent office has more leaks than a Soviet submarine, but up until now it's only been small cars that have been able to trickle out (see: the facelifted Mazda MX-5 and Nissan 370Z Roadster). But the dam seems to be giving way as a whole Mercedes limousine has managed to squeeze though and into the public realm, and our European compatriots at Autoblog Spanish have got the sketches to prove it.
Like the spy shots we've seen before, these patent sketches provide further proof that Mercedes is preparing to launch a stretched Pullman version of its new E-Class. Several extension options are apparently being prepared, ranging from a modest wheelbase extension all the way up to a full extra set of doors. Expect all manner of luxury equipment to find its way into the enlarged cabin, from entertainment systems and courtesy lighting to power reclining seats and fold-down picnic tables for that ultimate Grey Poupon experience.
