Honda reveals more details of new Insight prototypeHonda has released new images and more specs for a new Insight prototype that's set for its official unveiling at the Detroit Auto Show next week. In fact, Honda has confirmed the prototype previews a brand new sedan that's set to go on sale next year. It's certainly a lot more conventional in appearance than its two predecessors of the same name, so Honda presumably hopes it will be third time lucky for the nameplate this time.
