An anonymous reader writes: Back in September, Porsche unveiled a prototype for an electric vehicle. They were trying to gauge interest and figure out if they have the technical know-how to build one. Now, they've made the decision: Porsche's "Mission E" project will put an all-electric vehicle on showrooms by the end of the decade. Wolfgang Porsche said, "With Mission E, we are making a clear statement about the future of the brand." This is a reference, of course, to Porsche's parent company, Volkswagen, which has been in trouble for tampering with emissions standards recently.
