It won't even be released in Europe for another month -- and it won't get to the U.S. until next year -- but already, sales for BMW's (NASDAQOTH:BAMXF) electric i3 have been strong. BMW's CFO said this past week that the company already has 8,000 preorders for its first mass-produced electric car -- and BMW is already looking at increasing its production capacity.

Does this mean that electric cars are finally ready for prime time? In this video, Motley Fool contributor John Rosevear looks at how the new BMW stacks up against Tesla Motors' (NASDAQ:TSLA) hot Model S sedan -- and at how the i3 could be BMW's first step in a big push onto Tesla's turf.
