The X6 is the auto industries only crossover? Somebody better tell Nissan/Infiniti, Toyota/Lexus, Ford/Lincoln, GM, Mazda and Chevrolet to replace their Murano/Rogue, Highlander/RX, Flex/Fusion/MKX, Acadia, CX-7/CX-9 and Equinox.

Since when is the one who arrives last to the party the inventor of the segment? Precisely why BMW has to invent new segments that nobody wants. Still waiting for that Sports-Activity-Bus to be announced, I'm sure that should be another segment buster.

There's basically no difference between CUV and Crossovers.

I suppose Acura doesn't feel the RX's lines are swoopy enough. Except for the rear tailgate, the RDX is probably more sporty and raked than the X6.
