Time for a helpful hint on this one, I think.
As far as I know, this car existed only as a concept, which was developed over a period of several years. I don't think a full-scale prototype was ever made.
The puzzle photo was scanned from a periodical publication, and I have not been able to find it online.
However, this car is mentioned in at least two articles in a journal which can be read online free of charge. One article has only line drawings, but the other has an artist's impression in similar style to the puzzle photo, which is shown below, but you can see that it looks significantly different. The dimensions and technical descriptions of the two are the same.
In terms of publication date, the puzzle photo is the later of the two, though the one below looks "purer" in style. However, the later one, with proper headlights, a higher waistline and roofline extended backwards to give storage space behind the seats, is clearly a more practical design.
Finding either picture will provide enough information to answer the puzzle question, which is who designed this car, and what was unusual about it from a mechanical point of view?
Good luck!
