I agree Hybrids need to be more efficient, I doubt very much wether this Ferrari has an off the shelf Ferrari system.
Car like the Prius and now the Honda CRZ are cars with supposed green credentials, but when driven in the real world they lose the plot.
Stop start is about the only difference.
But, I think with refinement, Car makers will learn to use the tech alot better.
Its interesting that Luca DM has said this is not to get Ferrari "green". He wants it to be used in addition to the power of fossil fuels, much like KERS.
Personally I think this is flawed.....much like the 599 hybrid
