The PowerWheels cars do not use motor controllers - the current goes directly through switches. Those cars are already know to catch on fire and a larger motor would not help the situation. PWM controllers would be very expensive. Also, high current switches would not be cheap if you decided to go that route.

I know you want electric but I would seriously look into gas as they are fairly simple, easy to implement mechanically, more powerful, longer runing, and can be very economical. They are not dangerous if used correctly.

Could you explain the project a little more so I can get a better idea of what you are doing. I love thinking about and making personal vehicles.
