Well, it's just a game
VAZ E11011 was inspired by Mini Moke, which was used by one of the factory officials to drive throught the plant. It was based on VAZ E1101 Cheburashka prototype mechanicals, so it was a front wheel drive car with a small displacement engine. VAZ produced five bodies, only two of which were used.
On the pictures you can see the 1:5 mockups - first and second versions accordingly. First version, with sharp edges, was taken as a basis for a project. Third picture shows both mockups together. Further there are real cars - yellow and red ones. The car was called 'Autoroller' among the factory workers, but that was not a model name, but rather a vehicle type. Designer himself called the car 'Letuchaya Mysh', i.e. 'the Bat'.
The pictures are taken from an awesome book about VAZ factory and cars which I don't have (but the Internet does). There are a bit too many unseen cars to uncover it, sorry, but maybe the interested ones would find it on themselves
