BMW continues to march to the beat of a different drummer when it comes to CUVs and SUVs. In the BMW world they're called SAVs (Sports Activity Vehicles).
Thee brand's early SAVs (X5, X3) were relatively conventional utility vehicles. But things took a more bizarre twist with the introduction of the X6 in 2008 – a somewhat mal-proportioned fastback sedan body style on an elevated SUV platform.
Like a foreshortened X6 it sits tall, with a particularly high tail, and looks compressed longitudinally in profile.
In fact it is just 4,648 mm long, but with a width of 1,915 mm and a height of 1,622 mm, on a 2,810-mm wheelbase.
BMW says the Concept X4 offers a preview of the future of the BMW X family, with the production X4 scheduled to launch in 2014. It will be built at BMW's Spartanburg plant in South Carolina, along with the X5, X6 and X3.
It's not an all-new concept. American Motors offered an actual crossover coupe with all-wheel-drive as part of its Eagle lineup back in 1980. It lasted just three years before being dropped from the lineup.
