I think conversion kits will be go-to solution, assuming the costs of batteries and charging both drop as predicted. Batteries generally have fewer physical constraint limitations than internal combustion engines, so you can shape such batteries in ways that physical engines can't. You can always go with a hybrid approach as well, if adding torque was your objective.

I think we have about twenty years or so before we are far enough off the peak of global peak oil (which I believe we hit about fifteen years ago now) that gas for ICE vehicles is going to be too expensive for all but the wealthiest car owners, and in my experience, for every one of those people who looks at burning expensive gasoline as an indication of their wealth, there are five or six people who see it as senseless waste.
