I think the Williams flywheel is too dangerous and to much effort.
It needs to be spun at 100k rpm which means it generates A LOT of heat, which means it needs a vacuum and it's own air intakes. This results in LOTS of space occupied.
It also has a very strong magnet which is used to keep the flywheel spinning which could interfere with other car components, for example, the gearbox.
Porsche used it successfully... but it's all about weight when racing.
Cutting added weight
The weight penalty imposed by the addition of the hybrid system is 285 pounds (130 kg), with the flywheel representing just over 100 pounds (47 kg) and what Porsche calls the "portal axle" assembly up front another 150 (68 kg).
Asked what was next for the 911 GT3 R Hybrid program, Armbruster said that integrating the mechanical components (and cooling systems) would make sense.
The goal would be to get the hybrid GT3 down to the weight of the standard GT3, to make it possible to compare the two cars' fuel consumption and performance directly.
And, Armbruster added, "we will build a new car shortly with a new system" that will "get rid of the added weight."
Yes but it was packed in a 911 which is technically still a road car converted into a race car (or the other way around depending on your loyalties). However as you would expect an F1 car has a much tighter package meaning that if the flywheel is installed there will have to be a compromise in some other aspect of the car.
Also, i think that the mass of the batteries may be easier to place in the car in regards to the C of G as i assume they will require less volume and can be placed quite low, maybe under the fuel tank. Whereas the flywheel with all its components may not require more volume.
I loved watching that Porsche down the straights, absolutely awesome.
Everything i am saying is pure assumption, none of this is based on any raw informationSebastian Vettel, Youngest WDC!
