You have the Sports Utility Vehicle (SUV), you have the Crossover, or Compact, Utility Vehicle (CUV), and then you have the Sports Activity Vehicle (SAV). The final of these autos is a BMW creation, which spawned the X6 Sports Activity Coupé and now the X4 Concept. These two sculpted vehicles are attempts to basically combine a two-seater sports coupe with an SUV. BMW didn't release any information on the specs, but it's expected to be built here in the U.S. and should go on sale later in 2014. Hit the jump for the full release.
