Having launched in 2011, the current-generation BMW 6-Series Coupe (F13) and Convertible (F12) should be nearing the end of their life-cycles later in the decade. At this point, the company is hard at work on the design of the next model, due around 2018. But using its imagination, German magazine Autobild has served up its own idea of what the 2018 6-Series could look like. Drawing inspiration from current models and from future ideas like the Vision Future Luxury Concept, they've done a pretty sweet job of it.
