No.
Flywheels are useful when you have a fixed installation with no weight constraints because you get certain benefits over LiPo cells, namely longevity. As a matter of energy density though, they are awful compared to LiPo and could never efficiently be used in a vehicle. Also, the gyroscopic forces would be such that it would be impossible to steer the vehicle.

That's a solvable problem, and has in fact been solved by F1 teams that have used it - Mclaren won two titles with their KERS equipped cars. The cars are demonstrably far from 'impossible' to steer...
- mikeash 8y agoAll you have to is mount two of them rotating in opposite directions to cancel it out. The axles need to be able to handle the load but the rest of the car sees nothing.
