Concept cars are like unicorns -- they're so prevalent and vaporous, they're hardly worth remarking upon. Every so often, though, one pops out into the ether that's really worth a second look. Lotus' Evora 414E Hybrid concept certainly fits into that category.This plug-in car boasts (or would boast, should it come into existence), 1.2 liter, three-cylinder engine, independent electric motors for the rear wheels, with a range of about 300 miles. The glass engine cover pictured above, however, is just one of the features we find ourselves double-taking here. The Evora 414E would also pack some 'vroom vroom' noises by way of its audio system to take care of the ever-pressing danger of silent auto engines. The engine can operate on alcohol-based fuels or regular old gasoline, and the battery-only range is in the neighborhood of 35 miles. The Lotus Evora 414E hybrid will be unveiled at the Geneva Motor Show.
