Please forgive my bluntness, and allow me to cut to the heart of the X6-dissenter argument right at the top. Yes, BMW will sell you a 2015 BMW X5 M that is the motive twin (I assume) of the X6 M you're here to read about, that is also cheaper, roomier, and more conventional in appearance.

For many of you – especially the old guard that hears the descriptor "Sports Activity Coupe" and proceeds to unlock the gun cabinet – that's all you need to hear. Because, although the fickle community that consumes and comments on internet car culture seems to be fine with typical-looking SUVs and wagons packing performance-enhancing goodies, the idea of slanting the back of one turns them right off.

And yet, BMW continues to sell the things; more than 250,000 units have be delivered in the X6 series' history. As if that weren't proof of concept enough, blood-rival Mercedes-Benz has unleashed theGLE, a coupe-like crossover of its own, complete with AMG pedigree.
