It is difficult to look more late 70s/early 80s than this car :)
But interestingly, the blue car behind it in this picture looks almost like the design of a modern city car from today to me. So that's where the real vision was?

EDIT: I might be wrong, I assumed the photo was from the 1980 Paris Salon show due to the article text above it, but it's probably from later. Oops.
