Combining some of the best elements of cars like BMW's 6-series (check out the front third of the car) and Audi's R8 (the midsection) with Aston Martin features (rear haunches) and yet coming out with a final product that seems totally original is a feat that has largely escaped the Chinese stylists that have taken a similar approach to design.
Still, it's nothing more than a rendering, and will not be produced by BMW, although some enterprising individual or coach builder could finance a one-off model. One can only imagine what a beast it would be, powered by the V10 from the M5 - or even better, rebranded as an Audi with a mid-mounted diesel V12.
