Both car had strong similarities : both
from Dural, both developed by aircraft industries, both 350cc 2-stroke
engine based on the popular Jawa engine as applied in the Jawa
motorbikes, both sliding roof, both driver placed central in the front.
From the Moravan 2 or 3 prototypes have been built, at least 1 still to
exists, from the Avia 10 prototypes have been made, at least 3 still to
exist. ( prod.no. 3, 6 and 10 ).
About the Avia have been many publications, the car has been shown many
times in public, magazines etc. This must have been a very serious
project.
This drawing of the 1st prototype shows
a rather symetric car, body parts could be exchanged in order to reduce
costs of moulds.
However the next prototypes didn't show this advantage anymore.
