The Audi Sportback Concept appears to be pushing market segmentation to the limit. Always wanted an Audi luxury crossover that wasn’t tall like a Q7 but bigger than an A6? Read on.

To us, the Sportback, due for an official unveiling at tomorrow's Detroit Auto Show, most closely resembles the BMW X6, just a fair bit shorter. Details are still slim, but expect this to preview a production Audi A7 for some point in the future. That vehicle will rival the BMW X6, Mercedes CLS, R-Class and a swift kick in the pants when it eventually goes on sale. [Fourtitude via Autoblog]
