Peugeot and Ferrari in KERS development partnership
First, I'd like to know if you really buy that?
Admitedtly, KERS systems for F1 are radically differents from the LMP ones in terms of demands, thus are not "swapables" from one formula to another. Maybe it is possible to simulate some charging/discharging operations etc, but how truthfull would the gathered datas be? Furthermore testing without the SECU, which is the very central piece of the system.
Secondly, if we admit the possibility of such a deal, what would be the interest of Peugeot, running a system they cannot use or even learn from? (OK maybe a massive amount of money from Ferrari is reason enough).
Ferrari have been very clear about what they thought of the implementation of KERS for 2009, and they already warned Mosley and co about the costs of the program, which are in total contradiction with all the efforts to cut the budgets. The supposed association with Peugeot would certainly not help reducing the costs, but is blatantly a way to spit in the face of the FIA, showing them that the respect of the testing ban is down to the good will of the teams, and cannot be enforced by authority.
How long before we see an unofficial F1 testing session at Barcelona, with Trulli onboard the GTone, Alonso testing the Nissan RCP 92, overtaking Kubica's BMW V12 LM and Hamilton at the wheel of the Sauber Mercedes C11... Hey, double-thinking about it, it could be really nice.

But, joking appart, what exacltly prevents one of the constructors to order a R&D program to another company? From that viewpoint, FIA's attempts to control the team's expenses seems so lame...
