No it was different. A certain company did the design job for Kikkoman. The soy sauce bottle gained international design fame and is now part of the collection of the Museum of Modern Art in NY.

The team/studio that designed that bottle is also responsible for the design of this urban vehicle. I don't know if there's any source which mentions this particular car, but for sure the studio is mentioned on various sites.

is this GK Design Group's Small Car from 1975?

Yes, that's already worth a point.

To complete this puzzle you have to find the name of the car which apparently cannot be found on their site, but in my source, so another point is waiting.

GK-0 by GK Design Group's Small Car from 1973

[Allemano]

That's right though they named it actually ZERO not simply '0'. 
The final mock-up was completed in 1975 not 1973, but as I didn't ask for the year the point is yours anyway.
