This heavily disguised BMW test car has triggered rumours that BMW is working on a production model of the CS concept car. The spy shots show a large sedan, like the 7-series, but with unique elements at the front-end and a generally more sportier impression.

The luxury four-seater was intended as a rival for the Maserati Quattroporte and upcoming Porsche Panamera. But last month, BMW announced that it would be focusing on smaller cars, with which the production CS, likely to be called the 8-Series, was out of the picture. However, the latest spy photos most likely show further development of the super-sedan.
