Looking at this picture of the hybrid system

This is noticably smaller than the porsche system, and dare I say much smaller and lighter than Toyotas ultracapacitor route which Toyota are now admitting is circa 100Kg - cripes, looks quite neat actually, the front motor-generator is quite small, looks about 15Kg-20kg to me, I suspect the whole system is about 60Kg
I wonder if they will follow Toyotas boast of saying they could easily achieve 1MJ between braking points........perhaps they both might start to lobby the FIA/ACO in order to let the hybrid systems stretch develop, but if the y do I think they should reduce the fuel allowance further, as it should add fuel economy, not performance......hmmmmm
