I'm sure most of us have heard these rumour at the beginning of the season. Most people are rather skeptical of the idea and Ferrari themself have denied these rumours. Technically by removing the bellhousing and it's component makes the link between the engine and gearbox much more shorter. And being integrarted to work as a unit makes gear shifting to work much more faster and efficient.
From the seconds advantage per lap Ferrari have and the compact rear end of the chassis seems to suggest they might very well have achieved those rumoured technical advancements.
And i'm very impressed by the look of their periscope shaped exhaust exit..cool
