Next to all the major automakers debuting vehicles at the 2011 Frankfurt Motor Show is a lesser-known firm from Russia that operates under the curious name of Yo-Auto (ë-Avto).

The quirky Yo-Concept, unveiled today in Frankfurt, is one of four hybrid vehicles the Russian automaker is reportedly working on. And even though the Yo-Concept is not destined for production, execs say this unique concept previews the company's stylings and that it will function as a design model for all of Yo-Auto's future vehicles.

The Yo-Concept reportedly features some sort of extended-range setup similar to the gas-electric plug-in system that powers the Chevrolet Volt. Of course, the Yo-Concept's trickest feature has to be its novel curved doors that slide up and to the rear of the vehicle. Refresh your memory on how the Yo Concept's doors work by clicking past the jump to watch a brief video, then check out live pics in our high-res gallery and drop us your (yo?) thoughts in Comments below.

      Despite it has zero practicality, funky and creative door design.

      I would leave the doors up and wear a red batman suit.

      I still want to know if it's been designed to allow you to drive with the doors open.

      Not so sure about those doors. Looks like any crap on the exterior (mud, water, etc) would be wiped off and promptly deposited on the interior and passengers upon opening the doors.

      Super cool concept and lots of respect for the designers. And now for anonymous Internet criticism: The doors take too long to move if it's pouring rain out; the windows go down and you and the interior get soaked waiting for the doors to beautifully glide open and closed.

      A slight accident and it would also double as a coffin!

      And yet, they will continue manufacture 1960's FIATs known as Lada until the oil runs out.

      I don't know if it would work in the real world, but it's kinda fun to look at.
