BMW M5 CS on tests

An unusual prototype of a high-performance BMW M5 in the CS version passed new tests.​

It was the most powerful version of the car with the prefix CS that was tested.

The business class sedans were tested not at the Nürburgring, but at the BMW M test center. Paparazzi captured a car that has a different spoiler that turned out to be very similar to its counterparts that are present in the M3 and M4 cars in the CS versions. 

Additionally, the vehicle acquired a braking system, created exclusively from carbon ceramics. Add that the above machines also have similar elements.
