O.K. More research, apologies if people have seen this before.
Magneti Marelli has revealed it is to join Flybrid, Williams, Zytek and Bosch in offering an off the shelf solution for Formula 1. Its KERS is capable of a maximum energy storage of 400Kj per lap with a maximum 60Kw power boost as per the regulations. The system itself is fairly conventional, using a single liquid cooled brushless direct current motor generator unit (MGU), which operates at around 120 degrees C. Also included in the system is an in house designed KERS Control Unit (KCU) with a similar temperature capability. The battery pack is an ousourced part due to the complex chemistry involved in its development.
It was developed with a team (many suspect Ferrari) and is fully integrated with that operations powertain and is not an optional extra like some other systems.
It appers you are bang on white blue, those certainly look like connectors for coolant. Do you think there's some planetary reduction box in that billet nosecone? Looks like it's rigged to go onto the crank although it's going to need more support than that eh?...
I can only hope that me muddling through under the scrupulous eyes of those that already know may provide a little information to those others who haven't looked this far into it yet:)
