ah, one more thing, the argument that the mezger engine was the reason for no PDK is not fully correct, the 2012 RSR has now one.

Are you sure? The RSR's gear box is a sequential six-speed gearbox

This is my understanding as well.  Just because the RSR is now equipped with paddles, that doesn't mean it's using a PDK gearbox.  It's a sequential six-speed gearbox (designed for racing), which just happens to be operated by means of paddles rather than a sequential stick shift.  Far cry from a PDK.
