    is "better", yes.  But when you total up all the losses in the electric generating and distribution system (batteries, chargers, transmission lines, coal fired boilers) you get back to the more basic question:

    Is internal combustion more or less "efficient" than external combustion?

    There's a reason "steamships" and "steam locomotives" were replaced by diesel, and that reason has to do with efficiency.  It is not at all clear that the whole-system efficiency of electric cars in any higher than internal combustion . . . particularly when the ICE is coupled with on-board hybrid support to increase its efficiency even further.  So it's not at all clear that electric cars bring any benefit in CO2 reduction, unless the electricity to run them comes from somewhere other than fossil fuels.  At present, in most places, it doesn't.  Most electric cars are in fact coal burning cars (or natural gas burning at best), and they are in fact "dirty".  Hybrids are, in fact, "cleaner".

     The "solution" to the transportation CO2 problem is not "electric", it is carbon neutral synfuel, coupled with smaller and more efficient engines in the car.  I get 31 mpg overall in a Scion xB . . . a "hybrid" engine of the same output would give near 50 (look at the Ford C-Max).  An "electric" motor (and batteries) giving the same power and range would weigh 500-1000 lbs more and cost far more to operate unless provided with subsidized electricity and free battery replacements.

    It is not "more efficient" to simply pass those costs on to someone else.
