Yes, this car is called 'Ponghwa-ho' (봉화호).
And a description from my DPRK archive:
Illustration of a propaganda/parade vehicle shown in a North Korean art manual. Left hand drive and Japanese-inspired. Note the roof opening and the rear doors placement. There also seems to be no room for a trunk or a rear hatch opening. The inside seating contains a special seat and desk for the propaganda person to use the loudspeakers through a microphone and the rear seats are foldable. Its name '봉화' means 'Lodestar' in rather archaic English. This car doesn't exist. It is just an example of art design.
Name comes from: en.wikipedia.org/wiki/Ponghwa_Revolutionary_Site
