High drama in the electric car world: According to the New York Times, electric sports-car manufacturer Tesla is suing Henrik Fisker and Bernhard Koehler of Fisker Coachbuild, charging that Fisker “fraudulently” signed on to design Tesla’s “White Star” sedan, sabotaged the sedan project by doing substandard work, then stole confidential information and went on to build a competing car—the Fisker Karma.

GM announced yesterday that the company plans to release its electric car, the Chevrolet Volt, by the end of 2010, despite concerns from employees that the date might be too ambitious.
