Electric is going to be the hybrid solution until hydrogen technology is implemented, in my opinion.
Pros to electric motors:
-Zero emmisions
-INSTANT hella torque (electric cars actually make fantastic race cars, just not the daily driver electrics offered to the mainstream)
-Fueling is the cost of electricity
Cons:
-Batteries (at least for now) will need routine replacement, and are quite expensive.
-Range of travel, if dedicated electric
-Technology is still in its infancy so it's prone to some developmental delays.
-no exhaust noise (con for me)

They typically are more expensive to maintain than conventional vehicles, mainly because, as I mentioned before, it's a relatively new technology.
