Tesla Motors(NASDAQ:TSLA) vehicles far outpace its competitors' when it comes to electric range capacity. The Model S has a 75 kWh battery with a range of at least 240 miles, while its closest competitors -- the Nissan (OTC:NSANY) Leaf, the BMW (OTC:BAMXF) i3, and General Motors' (NYSE:GM) Chevrolet Bolt -- fall far short.
