Rumors reached fever pitch that Toyota is set to green light its futuristic Endo supermini, when the tiny concept car was spotted during testing in Japan. The Endo is Toyota’s answer to the Smart fortwo. It amazingly offers space for four passengers, including the driver, in its compact size. The stubby looking concept debuted at the 2007 Frankfurt Auto Show.

Other unique features of the Endo include a vertical tailgate, wrap-around windscreen, two-tone body work and doors that hinge away from the car’s body to improve access to the cabin. The concept car even featured an avant-garde flat screen dashboard. However, if the Endo will indeed see production, it will have to be in a more conventional approach to keep the costs down. As for now, the Endo production model is expected to hit the markets as soon as 2007. Or will it? We’ll see next year.
