kinetic energy regeneration systems are being used on this year's F1 cars. for 25kg extra weight, a flywheel energy storage unit can supply six seconds of 60kW of electric-assist. Not only is that an 80hp boost, it's from an electric motor, which means instant torque.

it has just occurred to me that such a boost from an instant torque electric motor could also assist in spooling up an engine. Six seconds is plenty to boost an RB26 until the turbos come online.

I guess the most similar effect would come from nitrous (an 80-shot would be about what you'd get from a single fogger programmed to aid in spoolup, give or take some), but a KERS system would, for not that much more weight, never require tank refills.

F1 reports that the 60kW motor weighs only 8kg...? I wonder if that could also serve as the starter motor? (I actually don't know where the starter motor is on an RB26, surprisingly enough!)

thoughts? I definitely plan to, in some distant (or not-so distant?) future, to convert my car to full electric with 100~150kW motors per wheel. Just requires several generations of battery development...
