Tesla Motors(TSLA -3.55%) 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 (NSANY 0.54%) Leaf, the BMW (BAMXF -0.19%) i3, and General Motors' (GM -0.05%) Chevrolet Bolt -- fall far short.
