I'm very interested in the hardware of KERS in the M3. F1 cars KERS systems weigh 25kg but are limited to 20% efficiency in order for the system not be overwhelmingly beneficial. At 100% efficiency KERS must be amazing. BMW will hopefully keep the weight of the hardware to a minimum so that KERS don't become dead weight during driving when you don't need a boost.

Only the Merc F1 KERS does weigh 25kg, other systems are heavier, even in F1. I concur on your other points, though.

Let me say 7:40 on the ring. 4.400 cc. That's all for now.More news before those dates. We all hope all I was told, will happen..

Sounds so great

4.4 liter would/shoud/could result in around 460 hp, if they keep 105 hp per liter

Ahh... but they will not, not for real, they will say that they do, but that will only be true if you take the power from KERS in account - and we don't
