Has there been any thought to having a "Ultra-Efficient" model (Accessory Package)? If the price was right, I would pay for a package that included additional efficiency enhancements. These would be things that didn't make the final car because the marketing or pricing folks didn't think they would work but the engineers found improved the efficiency. Things like, rear wheel covers, internal (and running / break) OLED instead of regular lights, an "extended battery pack" instead of a spare tire, a solar charging kit, and other ideas mentioned on this forum.
