Did find this on the transmission:
All through the development of the 2012 Pagani Huayra, there has been rumors regarding the transmission selected for the car, but Pagani decided to fit an automated manual system for the car which is ideal for a race-bred car like Huaya, but at the same time he came to know that the dual clutch gearboxes of the car are still limited by their torque capability. So, finally the Huayra comes with a quick-shifting single-clutch automated manual transmission, which is pretty much like the one that we’ve seen in the Lamborghini Gallardo LP570-4 Superleggera and Audi R8 5.2 FSI. The car comes with a 212-pound, 7-speed transmission built for Pagani by XTRAC, which also provided the transmission for the Pagani Zonda R.
Wouldn't pretend to understand it all !!!!
e.g. what ever this means:
